PRESIDENT’S MESSAGE Have you ever stopped and consider what or who has influenced you in your green industry career? For my business I have had several people: 1.

2.

Dean Ricci

My wife, who is my economic and business sounding board that I needed to make it through the tough times. She also helps me wordsmith my Presidential letters.

My Dad, who actually worked with me for eight years while the business was struggling through employee issues and developing trade best practices.

3. Monroe Porter and Dan Kohler, my business consultants, who showed me the way to run a profitable business and who helped me hone my business and people skills.

4. George Brenn, “The Godfather of the IAH”, who taught me to become a Master Indiana Accredited Horticulturist and involved me in the INLA organization.

5. Wayne Gruber, who has consistently pushed myself and my organization in better and innovative plant design and use.

All these people have helped shape myself and my company to what it is today, however I would like to focus on Wayne Gruber. At the 2022 IGE show this January, the INLA allowed me to present the Award of Merit to Wayne. It was a privilege to give this award to one of my influential people and a close friend. Looking at Wayne’s work history, accomplishments, and his passion for the industry, it is clear why he was deserving of the Award of Merit.

Wayne is an innovator in his field, and his commitment to improving our industry is unmatchable. I want to thank him for sharing his vision with me and inspiring me and my team.

EXECUTIVE DIRECTOR’S MESSAGE Welcome to my new rendition of a favorite past-time event, even though it was on hiatus for one year. Naturally, I am referring to the Indiana Green Expo, the 2022 version. As they say, you never know how much you miss something until it’s gone, but when it returns it gives you a greater appreciation for the emptiness, to find ways to hopefully never let it go away again.

Seemed like ages ago we had to do all the planning through completion for the Indiana Green Expo. I guess it was a good thing we still had checklist to follow, but I must admit, I found items that I Rick Haggard had left off until the event was actually extremely close to taking place.

After hearing about other similar trade shows, being impacted directly or indirectly by the Omicron COVID variant, I was kept awake nights worrying that our event might suffer the same fate as others. Not our event though!

Workshops started Monday, January 24, 2022 and coincided with move-in for our trade show exhibitors even though it was bitter cold and had a slight dusting of snow. Overall turnout and progression of exhibitor setup, as well as the educational workshops, continued throughout the day. I had never seen as many anxious and possibly surprised faces on exhibitors actually setting up booth spaces, some appearing in shock this was actually happening in-person, while others had that infamous befuddled look akin to a deer in headlights on how their display goes together.

There is more detailed information on the trade show and award ceremony in the Indiana Green Expo recap on pages 8-18. (Please do not worry there are pictures to keep you entertained instead of just my eloquent verbiage to digest!)

I would like to take a moment to update our membership of some interesting additions that will help keep everyone more current on INLA news and events. In the very near future, we will be having a new social media platform to keep all members better connected and enable better communication. The plan is to create a more palatable and up-to-date posts that all members in various areas of the state can access by visiting the INLA Facebook and Instagram pages. Yes, even this dinosaur has become accustomed to social media and realize that the magazine is great to have, but an event, either planned or spur of the moment, needs social media to create a must-attend atmosphere and to reach members throughout the state more easily.

Another little bit of business regarding the INLA membership fees. After hearing from members about our fees and classifications, the following is a proposed dues fee structure for Regular/Active members starting with the next fiscal year. The new dues will be sent in mid-May and due June 30, 2022. They are as follows and please select based on gross revenue not net profit: Classification Annual Dues New - Platinum (over $3,000,000.00 gross)....................$ 450.00 Class A ($1,000,000.00 to $3,000,000.00 gross).............$ 375.00 Class B ($500,000.00 to $1,000,000.00 gross)................$ 300.00 Class C (250,000.00 to $500,000.00 gross).....................$ 250.00 Class D (0 - $250,000.00 gross).......................................$ 200.00 Satellite Company * ........................................................$ 100.00 * any company with same name but different location(s) per location Please feel free to contact me if you have any questions.

Indiana Green Expo Live – 2022 Recap

Photos by Meghan Gillen and Mary Breidenbach

Rick Haggard, INLA Executive Director A truly heartfelt Thank You for making the 2022 Indiana Green Expo a true success story.

To all individuals that offered assistance to be sure this event happened without any major setbacks, even though we were faced with another COVID variant. To all the speakers that enabled us to have an educational session that would rival any national show. To Donnie Duke of Arborgold Software, and formerly of Engledow Group, for offering his services as the ICPI Educator for the two-day workshop to increase proper training for hardscapes. To the exhibitors making the effort to have a trade show that was almost 90% capacity, and to Randy Brehmer and his MRTF/INLA volunteer entourage for strategizing and expediting of movein and move-out of exhibitors and their accompanying displays. To the registration staff with the educational registrations coordinated by Ashley Breed and Colleen Flynn, and trade show/exhibitor registrations primarily handled by veterans Julie Gillen and Vickie Newell. Naturally, with the volume we had, other assistants and staff mentioned above helped wherever needed.

To our passionate Sponsors that help offset the cost of putting on an event of this magnitude. We had the stalwart corporate sponsors of Blue Grass Farms and Brehob Nurseries, as well as new corporate sponsors of Estes Material Sales and Townsend Arborcare! Thank

Attendees answer questions to win gift certificates provided by IGE's four Corporate Sponsors before the opening of the 2022 Trade Show.

you once again to the Engledow Group for the exquisite lounge assemble and to Schuetz Insurance Services for sponsoring the lounge refreshments during the trade show. Also, special shout out to Syngenta for sponsoring the lanyards and to Proven Winners for being a session sponsor.

Many exhibitors that had displayed in the past were not able to come to our show and we missed them. Hopefully, seeing the pictures of the show traffic will bring them back next year. Some had safety concerns even though I mentioned that the Convention Center is one of the top five convention centers in the United States to host events safely. Visit Indy reminded me that according to USA Today readers, Indianapolis ranked #1 in the Top Ten Convention Cities in the United States.

I truly hope to see all of you again next year at IGE 2023 — tentatively

planned for January 30 to February 1, 2023. There is a slight issue with the hotel space at this time, as there is a “small” city wide event that would require 2,500 hotel rooms. The hotels reserving a bulk of those rooms are The Westin, The Hyatt, The Omni, The Marriott, and The Hilton.

We are working diligently and with Visit Indy to secure a block of rooms at either another hotel, such as the Embassy Suites or Crowne Plaza. The other possible option is a smaller block of rooms at the above hotels, that adjoin the convention center via skywalks.

Please enjoy the pics!. More photos posted on INLA's Facebook page.

INLA AWARDS RECAP – INDIANA GREEN EXPO 2022 Finally, Kent Wilhelmus, Awards Committee Chair, was able to announce and present the Green Excellence Awards to our recipients, in front of over 100 attendees.

The Green Excellence Award winners received the posters of their 2020 Winning submittals and the 2021 Green Excellence winners received plaques and posters inperson. Due to the virtual nature of the 2021 Indiana Green Expo, the 2020 Green Excellence Award Winners finally received their 28" x 44" posters, as their individual plaques were dispersed to the winners after the 2021 IGE Virtual event. The only absentees unfortunately were Andrew Marrs Landscape Design for their Special Project and John and Suzie Platte of Perennials Plus, for the Nursery and Landscape Achievement Award. I plan to visit them soon and get a pic when presenting their actual poster.

I was honored to give Robert Johnstone his Award of Merit Plaque as the designated winner for 2020. Robert was President of the INLA in 2014 and his dedication of raising money for Indiana Nursery Endowment Fund to be utilized by vocational schools, industry related certifications and scholar-

ships has continued to embellish the professionalism of our industry. Thank you Robert for raising the awareness that our future comes from the youth we acknowledge and give support towards their career.

One of the changes we made in the interest of time, was to bring up the companies and hand out the plaques based on the number of winning entries they had. Also, Automatic Supply sponsored the 2021 Lighting Category and Rick Hughes, Automatic Supply's representative, gave that category's award out for the evening to the winner, Franco Landscaping.

INLA Annual Nursery and Landscape Awards 2021 NURSERY AND LANDSCAPE ACHIEVEMENT AWARD

Mark Goss & Tom McGee To be awarded annually to individuals with good standing in the industry who have given freely of their time for the strengthening of the green industry in Indiana.

Price Nurseries originated in 1927 and in 1990 it was purchased by the three amigos — Tom McGee, Mark Goss, and Jim Kenny and they have been providing beautiful plant material, garden design, and installation since then.

What I really appreciate the Price boys for is their energy to learn and their commitment to relationships. All three have been a sounding board for me (as I'm sure many of you) during these events to listen and freely share their tenured experiences and knowledge with anyone that would ask.

Tom McGee served as INLA's president in 1994. The company, Price Nurseries, has exhibited here at the Indiana Green Expo since the early 90’s and even hosted the summer meeting in the 50’s.

Tom McGee, Mark Goss, and Jim Kenney

And if you have never seen any of Mark’s work in person, I would contest he could have been born with a set of FELCO 2's in his hand because the espalier and fan pruning he does is second to none.

So get to the point right…

What I'm saying Tom and Mark, is that many would say you two are as good as gold to which I would agree and say, "Yes!" Shalom to you men and may you be blessed.

Rick Haggard, Tom McGee, Mark Goss, Dean Ricci, and Gabe Gluesenkamp

Taming Invasive Species with Plant Breeding It is welcome news that people now recognize the threat of invasive, exotic species that can displace native species and alter our native ecosystems. Gardeners, nurserymen, landscape architects and other land stewards should all see the need to act responsibly to preserve our native ecosystems. No one wants to be responsible for the next purple loosestrife, kudzu, or multiflora rose, all well-known examples of problematic, invasive species. We can all see that the proverbial Pandora’s box has been opened and now the question is how do we close it.

State and local lawmakers are attempting to solve the problem with legislation that bans the sale of invasive species. Most of us can agree to give up kudzu and garlic mustard, but should gardeners and landscapers be forced to forgo some of our best performing ornamental plants? The question might be irrelevant if we better understood that weedy, seedy species can be tamed with plant breeding.

Plant scientists, horticulturists, farmers and gardeners have been selecting and breeding cultivars since the dawn of agriculture. Historically, cultivars have been developed to produce greater crop yields or larger, more colorful flowers. These same techniques can and have been used to produce well-behaved, environmentally friendly plants that are not invasive threats like their parents. There are essentially five methods of taming an invasive species; flower doubling, male clones, wide crosses, triploids, and mutation breeding using chemicals or irradiation. One of the oldest methods for taming a weedy species is to create fully double flowers, where the reproductive organs (stamen and pistil) are turned into petals. Double flowered cherry trees (Prunus sp.) are an excellent example. Have you ever seen fruit on Kwanzan cherry tree? Doubled flowers typically first occur as chance mutation and are then exploited by plant breeders to increase the petal count by transforming all the stamen and pistil. Typically, the more petals you have the greater the degree of sterility. Rose of Sharon, Hibiscus syriacus is a good example of a weedy garden plant that was tamed by means of doubled flowers. There are a number of fully double flowered cultivars in a range of colors and none of them set much, if any, seed.

Selling and planting cloned male plants is another very simple way to eliminate seed and thus invasiveness. Male plants produce no fruit or seed and are rarely invasive. Unfortunately, this method is limited to plant species that are dioecious, having male and female flowers on separate plants. There are a number of plant species we could tame using this method, including Amur cork tree (Phellodendron), bittersweet (Celastrus), mulberry (Morus), poplar (Populus) and willow (Salix).

Creating a mule, or making a wide cross between two distantly related species can solve invasiveness. Mules rarely produce offspring. The key with this method is finding parents with the proper amount of genetic distance. If they are too closely related the offspring can be fertile. If they are too distantly related, it’s impossible to make a successful cross. Dr. Tom Ranney at North Carolina State University has used this technique on several potentially invasive species. He developed Sunjoy Todo® Berberis x ‘NCBX1’ (see Table 1, page 24) and Golden Ticket® Ligustrum x ‘NCLX1’ using the wide cross technique to reduce fertility. Dr. Dennis Werner, also from North Carolina State University, developed the Lo & Behold® Buddleia series utilizing wide crosses.

To evaluate female fertility, plants were arranged outdoors in a completely randomized design prior to flowering in Mills River, NC. Study plants were intermixed with 40 additional Berberis taxa to ensure for optimal cross pollination conditions utilizing natural pollinators. Individual branches were marked and the number of individual flowers on each branch was record. Fruit were collected when mature. Seeds were extracted, counted, sowed, and stratified for 90 days at 43° F. Pots with stratified seeds were then moved to a greenhouse maintained at approximately 70° F for 90 days and the number of seedlings were counted for each replicate.

One of the more useful methods for taming an invasive species is to create a triploid (3x) plant, which is one that has three sets of chromosomes instead of the normal two, called a diploid (2x). This was the technique used to create the seedless watermelon. The process starts by treating young seedlings with colchicine or oryzalin which doubles the chromosomes, creating a tetraploid (4x) plant. The tetraploid plant is then crossed back with a normal diploid plant.

The resulting triploid seedlings are often rendered sterile or nearly sterile. Double Play Doozie® Spiraea japonica ‘NCSZ2’ is a seedless triploid as well as a wide cross. One of the potential added benefit sterility is that the plant puts its energy into flowering instead of setting seed.

With Double Play Doozie® Spiraea the results are flowers all summer long.

Seedless plant mutations can also be induced by using chemicals or radiation. For example, seedless oranges, grapefruit, lemons and other citrus fruit have been created by using gamma radiation. Dr. Ranney used irradiation to develop the seedless Sunjoy Todo® Berberis x ‘NCBX1’. All of the aforementioned techniques have been used to create seedless ornamental plants that were otherwise considered weedy or invasive. We now have seedless ash, barberry, bittersweet, buckthorn, butterfly bush, mulberry, privet and rose of Sharon, and plant breeders are working on Amur maple, Bradford pear, Norway maple, as well as other useful, but invasive species.

Promoting an exclusively native plant agenda underestimates species that are not indigenous. Gardeners, like environmentalists, are proud of our natural heritage and want to preserve native habitats. They want to do what is morally right, but they also want to create beautiful gardens in our man made habitats. Cities and suburbs present challenging growing environments and exotic plants often perform better than native plants. Contrary to popular dogma, native plants are not more adaptable than exotic species, and they are not more resistant to insect and disease attacks. Quite the contrary, exotic species are often used by plant breeders to create new, pest-resistant cultivars that reduce the use of pesticides.

The cultivar solution is the answer to the complex problem of invasive species. We need to embrace and promote safe, seedless cultivars regardless if the species has been banned in our state or market. The time to act is before a plant species is banned. Legislation by state governments that restrict the sale of invasive plant species should include a means for exempting non-invasive cultivars regardless of species. As the green industry, we need to lead and show others that we are serious about the environment.

Jackson’s Nursery, Inc. Mary Breidenbach, INLA For over 50 years, Jackson’s Nursery, Inc. has been growing to become a leader in the nursery and landscape design/build industries in southeastern Indiana. Today, secondgeneration owners, Carl and Rhonda Jackson run Jackson’s Nursery, which offers a garden center, a wholesale nursery, and design/build landscape contracting services.

Carl’s father, Eugene, who enjoyed propagating and growing plants on his farm as a hobby in Greensburg, Indiana, started the business in 1965. In 1974, Carl joined his father as a partner. And today, Carl and Rhonda’s son, Gene, works with them as the landscape crew manager.

For the Jacksons, success has come with a lot of hard work and innovation. This is evident in all areas of their business and in their most recent additions.

For a garden center to operate in the countryside outside Greensburg, it takes some bold moves to be successful. To do so, the garden center provides a large variety of new plant introductions from Bailey Nursery and Proven Winners that their customers can’t easily find elsewhere, along with providing customers expert planting guidance. To reinforce this, the garden center’s outdoor digital sign aptly describes their unique new plant offerings by flashing the message, “Not your grandma’s landscape plants!”

The wholesale nursery side of the business offers 70 acres of shade and ornamental trees, junipers, and 16 varieties of arborvitaes, with hundreds of larger arborvitaes available.

Jackson’s Nursery regularly ships multiple semi-loads of nursery stock to surrounding states.

For over 40 years, Jackson’s Nursery has offered landscape design/build services for industrial, commercial, and residential projects. Carl and his son, Gene work closely together on all the design/build projects. So much so that Carl often refers to Gene as “his second brain.” Recently Jackson’s Nursery won the 2019 INLA Award of Excellence in the Special Projects category for one their design/build projects.

Innovative Solutions After Hurricane Ike came through Greensburg in 2008 and Jackson’s Nursery lost power for three days, they began to investigate generators that would provide water for irrigation nine months out of the year and keep heat and computers working during the winter. Following their initial solar installation in 2016, the Jacksons finally decided to expand their solar power system to produce their energy needs along with a Generac® power storage system for emergency and off-hour power needs.

“We couldn’t be happier with our decision,” said Rhonda Jackson. “Solar power reduces future electric bills, offers tax benefits, and is an investment with continuous financial and environmental returns.”

The Jacksons worked with Micah Lohrum, of Lohrum Electrical to design their solar system (which offset their electric usage by 108%), to streamline their two meters (connected to two separate pumps) down to one meter, and to install a standby Generac® generator. Rhonda added, “The savings we earned through tax credits covered the price of the Generac®. I’d encourage others to consider this power option.”

We are a recruiting agency specializing in seasonal to permanent staffing services for U.S. companies.

Several factors have left Puerto Rico with unemployment rates well above national average.

Since Puerto Ricans have been U.S. citizens since 1917, they are not subject to the many visa labor restrictions. While there are regulations with the Puerto Rican Department of Labor, we have developed a program to obtain the necessary approvals to recruit in Puerto Rico and provide Puerto Rican laborers. We have also established recruiting networks in other areas of the United States that persistently sees high unemployment and an excess of laborers.

In addition to the solar power system, Jackson’s Nursery realized they had an issue with the weeds growing on a steep ravine that was difficult to mow. The weeds were spreading to their nursery and garden center plants so they knew they had to find a solution. Rather than spray herbicides or mow a dangerously steep incline, in 2021 Rhonda and Carl decided to purchase goats to control the weeded area.

Having both grown up with livestock, Rhonda and Carl knew what to expect and how to take care of the animals, which helped in their decision. They ended up purchasing 15 goats (some goats were headed to be slaughtered) — no billy’s and all beautiful.

The results were phenomenal. Not only did the goats clean up the ravine in one season, but they were a hit with garden center customers and children in particular. “The children love to visit them. The goats are an added attraction and our goal now is to become a destination nursery,” said Rhonda.

In addition, they named the goats after plants. To make sure it was okay to use the names, they checked with the nurseries for their approval. Here's a sample: Penstemon "Blackbeard"

Hibiscus "Cherry Choco Latte"

Echinacea "Sombrero Salsa Red"

Phlox "Red Riding Hood"

INLA Membership The Jacksons have been Indiana Nursery and Landscape Association members for almost 50 years and have found that attending INLA meetings and education events, reading trade magazines, and networking with green industry innovators have helped them to grow their business.

Rhonda added, “When the pandemic hit in March of 2020, we were grateful for the guidance and information from INLA that helped keep our business open. Confused customers called to ask, ‘Are you open?’ We were proud to say that we are members of the Indiana Nursery and Landscape Association and that we were following the guidelines given to us by our trade organization to keep our business open. Reassured customers flocked to our garden center and we were blessed with the best year ever. Then 2021 topped 2020!”

EDUCATION

Take Time to Smell the Roses, and Inspect Them Too! Kenneth W. Cote, Indiana Department of Natural Resources, Division of Entomology & Plant Pathology Life is just a bed of roses. There are two different ways to consider this statement.

On the one hand, roses truly enhance the beauty of our landscapes and there is nothing that is more eye-catching than roses when they are in full bloom. Fragrant varieties add a positive stimulus to our experience in the garden. However, there can be drawbacks to having roses in the landscape. Many are labor intensive and prone to insect pests and diseases. Over the years there have been numerous improvements in the development of disease resistant rose varieties that require less maintenance than their earlier counterparts. These plants have preformed better in our landscapes, but we still find pest issues even on improved varieties. Roses and the rose family are susceptible to many different disease and insect pests, therefore it would be impossible to discuss all of them in an article.

However, I would like to share some of the more common problems that I encounter during nursery inspections.

Black Spot Black spot (Diplocarpon rosea) is one of the most common diseases of roses.

Many older cultivars are highly susceptible to this pathogen, but it can infect many varieties. Symptoms typically start to first appear in mid- to late-spring and appear as circular black spots with a diffuse margin.

They typically start towards the bottom of the plant or inside of the plant where there is poor air circulation. Symptoms develop at night when it is above 60⁰ F with leaf wetness. Therefore, it is a good idea to protect leaf tissue with a fungicide application 30

before such conditions occur. The pathogen can over winter on old leaves and stems.

Dormant applications of sulfur and good sanitation can reduce inoculum. Younger more tender growth is the most susceptible to infection. However, the practice of pruning roses frequently to generate additional flowers tends to keep roses producing new succulent growth. Pruning practices, cultivar susceptibility, and environmental conditions in Indiana that are favorable to black spot, make the requirement of multiple fungicide applications throughout the growing season necessary. Remember to alternate fungicides and know the FRAC codes of the product you are using in order to manage resistance.

Leaf Spot Diseases Many of the new cultivars are resistant to black spot; however, there always seems to be a tradeoff. Rose varieties that are more resistant to black spot seem to have more issues with other types of leaf spot diseases that can infect roses. Yes, believe it or not, there are other leaf spot diseases that can infect roses. Rose anthracnose (Elsinoie rosearum) is a leaf spot disease that can cause purplish spots with sharp margins.

The spots can be angular or somewhat circular. As time progresses, spots can coalesce, and can develop a greyish center.

Anthracnose typically thrives in cooler, wet weather but can cause defoliation and serious leaf spotting on certain varieties.

Cercospora leaf spot (Cercospora rosicola) can also occur on roses and looks similar to anthracnose. However, Cercospora is more typical during hot weather and prefers

INDIANA NURSERY & LANDSCAPE ASSOCIATION • www.inla1.org

temperatures above 85⁰F. It may require a lab diagnosis to discern which pathogen is truly present. Fungicide applications may be necessary to prevent defoliation from these diseases.

Black Spot

Powdery Mildew

Powdery Mildew Powdery Mildew is frequently found on roses including, Knockout Roses and Drift Roses. Many of the black spot resistant varieties seem to suffer from powdery mildew. Powdery mildew is a unique pathogen. It actually does not like leaf wetness but prefers relatively high humidity levels. These types of conditions usually occur in late-summer and earlyfall in Indiana. However, I have observed powdery mildew on plants at almost any time during the growing season. When you think of powdery mildew, you often think of the white growth growing on the topsides of leaves. High population levels of powdery mildew can also cause reduced growth, leaf cupping and leaf redness resulting in general plant stress. It may not directly kill your plants but can add to plant stress.

Downey Mildew

Downy Mildew A more serious issue is downy mildew of roses. Downy mildew is caused by the pathogen (Peronospora sparsa). Downy mildews are not true fungi but are closely related. This pathogen poses a serious threat to plant health and can become systemic in the leaf and stem tissue. Once it is there it is very difficult to control.

If plants are found with this during an inspection a destruction order is written.

Symptoms do not appear as a white growth on the undersides of leaves. They look like irregular leaf spots with a tannish center.

In some cases, early symptoms can look (Take Time to Smell the Roses continues page 32.)

INDIANA NURSERY & LANDSCAPE NEWS • MARCH/APRIL 2022

31

Take Time to Smell the Roses (continued from page 31) like phytotoxicity and vise versa. As downy mildew symptoms progress, symptoms become more apparent. The leaf spots and necrosis associated with downy mildew can be quite large and coalesce over time.

Symptoms on the stem tissue appear as red streaks. Infections can lead to abundant leaf drop. We frequently find this in plants being sold at garden centers in spring and it is moved around the nursery industry.

Rust During May of 2020 I had a verbal report of rust on roses from a new garden center in Vigo County, Indiana. I had never observed rust on roses in my 25 years of working with plant disease issues. However, rust was confirmed on Pink Knockout Roses in Putnam and Vigo Counties in 2020. The Putnam County location was found on tree roses that were overwintered for several years at this location indicating that this was not a new introduction but probably due to environmental conditions.

This was at first thought to be a new find in Indiana. However, rust has been reported on roses over 20 years ago, but it is not common in the state. Apparently, rust is a major problem on Knockout Roses in the western United States. There are nine species of rusts that have been reported on roses in the United States. Samples were sent to Purdue University where genetic analysis of the samples determined the rust to be Phragmidium tuberculatum. There are two other rust species that are known to occur in the Midwest, P. mucronata and P. americana. Rust was again found on roses in 2021 at several locations and it appears that this disease may be getting moved around on nursery stock. In some of the cases plants were traced back to out of state nursery sources. Providing plants with additional nitrogen can help plants grow out of the damage. Be on the lookout for this disease as we are starting to see more of it at Indiana nurseries.

Rust

Rose Mosaic Virus Rose mosaic virus is another disease of regulatory concern in the state of Indiana.

This is not a single virus, but symptoms can result from multiple viruses and are often called the rose mosaic virus complex.

Symptoms appear as bright yellow mosaic patterns on the leaves of infected plants.

There is not any cure for viral diseases, so if it is found during an inspection, plants are destroyed to stop the infestation from spreading. Often it is found scattered in nature or on a particular variety. If it is found throughout a shipment or symptoms are widespread at a location it could be an indication that an environmental condition is causing symptoms that mimic viral symptoms. Usually, I only find this on a few plants at time. It never seems to be a serious issue, but it is not all that hard to find in the nursery industry.

Sawflies Diseases seem to be more of an issue on roses than insect pests. However, there are some insect problems that can cause significant issues on roses. Several species of sawflies will feed on roses. These sawfly species are slug like in appearance and are sometimes called rose slugs or rose slug sawflies. Feeding injury caused by these insects typically appears in May as etching or fine skeletonization. Knockout Roses are particularly susceptible to damage from sawflies. They can often be found feeding on the undersides of the leaves. The rose slug (Endelomyia aethiops) is quite common in late spring and has one generation per year. Larvae are slug like but have an orange head with a green body. Another species that feeds on roses is the bristly rose slug (Cladius difformis). This insect causes similar injury to the rose slug but has two generations per year, which can allow it to cause more significant injury over time.

The larvae of the bristly rose slug differ from rose slug by having small hairs covering their bodies.

Spider Mites During hot dry periods in mid- to late-summer you may find spider mites infesting your roses. This is especially true for greenhouse grown roses. It is more than likely that the mite infesting your roses is the two spotted spider mite (Tetranychus urticae). These mites have a cream colored body with two dark feeding spots that are located on their sides. This species can cause serious injury to your rose if left uncontrolled. Overhead watering helps reduce mite populations but also promotes disease on roses. Large populations of this species can produce webbing, stippling, leaf yellowing and leaf drop, and eventually plant death. Control with a miticide may be necessary in some cases if environmental conditions are favorable for mite populations. Be aware of the type of fungicide you are using on roses and the control option for mites because there can be incompatibilities between fungicide residues and miticides that could result in phytotoxicity.

Thrips Thrips are another insect that can infest roses, especially the flowers. They have elongated tubular shaped bodies and can be dark colored or cream colored depending on the species. They feed on both leaves and flowers. However, they seem to prefer feeding on the inside of flowers.

Thrips feeding can cause small dark streaks on white flowers and small white streaks on dark colored flowers. This often results in shorter bloom time for a flower. Control of thrips can be difficult because they like to live inside flowers where they can feed on pollen and plant tissue. A few thrips can almost always be found in flowers, however if flowers are failing and you find hundreds of thrips in one flower it may be an indication that thrips are the culprit.

Japanese Beetles Japanese Beetles are a nuisance on roses. However, large populations can cause leaf skeletonization and defoliation of plants. Japanese beetles are often found in pockets in the environment. Some areas will have heavy infestations while others do not see many adult beetles. Adult Japanese beetles tend to congregate and feed on flowers. This causes flowers to have a shorter life span and can be a source of

frustrtation to customers wanting to buy roses or have roses on their property. There are numerous insecticides labeled for control of Japanese beetles and during the peak flight it may warrant an application to keep them out of your garden center sales area or to meet the needs of a concerned client. Overall, they are not usually a serious threat to the health of the roses.

Growing roses can be a challenge that offers great rewards in the garden. Consider the type of roses you wish to install and the amount of maintenance that is required to get healthy, abundantly flowering plants.

There are numerous cultural practices that help improve the general health of roses.

These practices have not been discussed in this article but should be considered when designing and installing roses. Good air circulation, ample sunlight, adequate and balanced nutrition and proper pruning all are important in maintaining healthy roses.

Being aware of the potential problems that can occur on roses will help you better manage roses through efficient monitoring for pest and disease that can prevent you and your clients from enjoying the desired purpose of having roses a landscape. Keep all of these points in mind when working with these plants and life will be a bed of roses.

Chapter 1 – Plant Structure, Growth, and Development (part 1) How plants work: Parts of a plant

Shoot system = vegetative and reproductive parts

Root system = all vegetative (growing) parts Balance between shoot and root system is essential for plant health. Root / Shoot Ratio Internal parts of the plant CELLS = building blocks: many different specialized cells with specific functions.

Growth processes occur inside cells.

TISSUES = organized groups of cells

Epidermal Tissue = plant “skin”

Meristematic Tissue = growing areas

Vascular Tissues = plumbing

ORGANS = groups of multiple tissues

Vegetative Organs = leaves, stems, buds, roots Leaves = factories: manufacture food, etc. Comprised of blade and petiole Epidermal layer = bread (Stomata are in epidermal layer) Palisade parenchyma cells = peanut butter (diagram on 3rd page) Mesophyl cells = jelly (most photosynthesis occurs here)

Leaves are attached to stems by the petiole at a node.

Stems = support for leaf and distribute food & H2O in & out of leaf.

1st year stems are called shoots.

Leaves are attached to the stem in alternate or opposite positions.

Stems contain the vascular system, comprised of Xylem and Phloem.

Xylem = vessels carrying H2O, nutrients & O2 from roots to leaves Phloem = vessels carrying products of photosynthesis within the plant

Xylem & Phloem placement is very different in Monocots and Dicots.

Dispersed throughout monocot stems (diagram on 3rd page)

Arranged in continuous ring around pith in dicots Stolons and rhizomes are modified stems.

Buds = the growing points of the plant; contain immature plant parts.

Vegetative buds = immature stems & leaves Floral buds = immature flowers

Different buds occurs in different locations: Terminal (Apical) buds @ end of a shoot Axillary (lateral) buds @ node in leaf axil Adventitious buds form in other locations (when a tree is topped) Roots = “anchor” for plant stability + entry point for minerals & H2O, and storage.

Taproot = thick, unbranched downward primary root, (some dicots) Fibrous Root = net-like mass of secondary roots (dicots & monocots) Fleshy Root = like taproot, but branched (perennials) Root Hairs grow from meristem (behind root cap): absorb H2O & nutrients.

Michorrhizae = root fungus (good) living amongst root hairs in symbiotic

relationship with root system: each benefits the other Adventitious Roots form on leaves & stems (rooted cuttings, layering).

Reproductive Organs = flowers, fruits, seeds Flowers = Sex organs of the plant: showy and smelly to attract pollinators Sepals = cover flower while in bud stage Petals = colorful to attract pollinators Stamens = ♂(male) produce and hold pollen (anthers and filaments) Pistils = ♀ (female) holds ovules (stigma, style and ovary) Complete Flowers = all 4 parts are present Incomplete flowers = 1 or more parts missing Perfect Flowers = have both ♂ and ♀ parts present Monecious = imperfect (♂ only and ♀ only) flowers on same plant Dioecious = imperfect (♂ only and ♀ only) flowers on separate plants

Hollies are dioecious (Ilex m. Blue Prince and Ilex m. Blue Princess) Fruit = the mature ovary from a flower: protects developing seed and is a vector for

dispersal of seed (via birds, animals, etc.)

Ornamental qualities often lasting longer than flowering aesthetics Seed = the next generation: contains embryo, has protective cover = seed coat

Laying a Foundation for Inspiration “A beautiful outdoor space should stand the test of time, every time.”

50 years ago, our founder had a dream. When Ed Bryant introduced the UNI-Stone® paver to the North American market, he essentially established the hardscaping industry here. Since then, we have continued to innovate and grow.

As a result, we are proud to have played a part in creating countless beautiful spaces, from backyard patios to landmark destinations across the continent. And we’re just getting started.

We know Ed would be proud.
