A Letter from the President Dear Members,
W
riting these presidents letters is always a challenging exercise. I have always felt that it provides me with a forum to present the agenda of the NLA to you, the members. Humor and a positive outlook have been the general underlying tone of all of my previous messages, because as an organization in the throes of tough times, these principles seem to me to be the best approach at a difficult situation. Obviously, markets across the board are at risk of potential ebbs and flows as the economy shifts, and we my friends are in the ebb. This is not new information; it is as prevalent a topic in day-to-day conversations as the replacement ref’s in the NFL. And the NLA, being only as strong as its membership, is not immune to these fluctuations. It is to this point that I now turn, because I am witnessing what, although it may have been there all along, I feel to be a potential breaking point for the NLA and its members. We as a board are constantly bombarded by the criticism of how we are providing value to the landscape industry. Well, this year’s golf tournament provides us with a spot-on representation of the precarious position that we currently find ourselves. This year, we scaled back the tournament and moved it back to an afternoon tee-off. We checked local calendars and confirmed that we were not bumping up against any local industry events that would cause attendance conflicts. We lowered the price dramatically to make it easier on the collective pocketbook. And most importantly, we attached a very personal, industry focused, charity aspect to the tournament. We had the opportunity to help Ole Marin, a long-time local landscaper, who suffered a stroke earlier this year, with the debt that he incurred while in the hospital and during his convalescence. It seemed like the perfect fit for the NLA to show how important supporting the local industry and our members was to us. I also provided a way to quell the “what-have-you-done-for-me-lately” criticism that I alluded to before. The result was that three landscape companies fielded teams at the golf tournament. We were so lucky that we had three at-large local member vendors (Western Nevada Supply, Hunter Irrigation and Crop Production Services) as well as three national vendors (Agrium Advanced Technologies, Colombia Seeds and Syngenta) sponsor the event. Thanks to these vendors, the NLA is still going to be able to donate $935 to Ole and his family. It is sad to think what this could have been. As I stood in the pavilion at Wildcreek Golf Course, where in years past I have witnessed standing room only crowds at this very tournament, I could only apologize to our sponsors and rue the fact that I was more than likely attending the last NLA Golf Tournament. I apologize for the rant, but this organization means a lot to me; primarily because this industry means a lot to me. I watch the day-to-day struggle, from the largest companies down to the smallest. The burden is all of ours to bear together and I intend to continue the fight. The Trophy Awards are the next large event on the NLA calendar in the first part of November, and even though the application process is closed, it would be great to see all of you at the banquet for a couple of cocktails. Good luck in the next couple months!

10 Most Frequently Asked Urban Forestry Questions 1). Do I need a permit to remove a tree on my property? No, however a Tree Work Permit is required before removing, pruning or planting trees within City Rights-of-Way or on other City property. Call the City of Reno Urban Forestry at 321-8371 to request an inspection, which is required before we can issue a permit. Keep in mind that we may not issue a permit to remove a tree unless the tree is dead, diseased or poses a public safety hazard. 2). When do I need to hire a Certified Arborist? A Certified Arborist is required for the removal, pruning, or planting of trees on City Right-of-Way or other City property. You may also hire a Certified Nursery Worker or Certified Landscape Technician if you are going to have any tree(s) planted on public property. You are not required to a hire a Certified Arborist for work on private property, but we highly recommend that you do. Call the Urban Forestry Office at 321-8371 for a list of Certified Arborists who own or work for tree companies in our area. 3). There is a City tree along the street that has dead limbs, when will it be pruned? We try to prune neighborhood street and parks trees on a rotational schedule once every 10–12 years however, it is a challenge for us to keep this schedule given the 22,000 plus trees we have to maintain and the limited staff we have to accomplish the task. After we inspect the tree(s) in question, we will determine its condition and pruning priority in relation to other trees requiring pruning. If the tree needs immediate attention, we will dispatch our tree crew to the site. 4). My sidewalk is cracked and being lifted up by tree roots, will the City repair or replace it? The City does have a limited budget to repair and replace sidewalks damaged by tree roots if the damage is caused by a City tree. If the damage is caused by a tree on private property, the property owner is then responsible for the cost of the repair or replacement. Call the Urban Forestry Office at 321-8371 to determine if a tree is on either on public or private property. 5). My neighbor’s tree is growing over my side of the property line, can I prune the branches on my side of the fence? The best advice is to talk with your neighbor first. It may also be a good idea to contact a Certified Arborist to evaluate the overall condition of the tree and then recommend a course of action. If you prune tree limbs hanging over your property and the tree is damaged or dies, you may be held liable. If your neighbor is not willing to cooperate in any fashion, you should contact your homeowner’s insurance agent for assistance in the matter. 6). There is a dead tree on my neighbor’s property that I am worried will fall onto my house or in my backyard where my children play. Can the City remove it? The City does not remove trees on private property but may require property owners to do so if a tree poses a public safety hazard. Call Reno Direct at 334-2099 to report the problem.
7). Does the City sell firewood to the public? Yes, firewood is sold to the general public during the months of September and March on Tuesday’s and Thursday’s only from 7:30 am to 1:30 pm. Customers should be prepared to cut their own rounds which requires a chainsaw and personal protective equipment. Customers must pay in advance by check or cash only and must sign a waiver of liability in order to enter the wood yard. Waivers can be obtained at the Park Maintenance Office at 2055 Idlewild Drive in Idlewild Park. The wood yard is located at 190 Telegraph which is off of Greg Street just behind the Grand Sierra Resort. The cost for the firewood is $75 per cord. 8). My elm tree is losing leaves, does it have Dutch elm disease and should it be removed? It is likely that your elm is infested with elm leaf beetles. Adult elm leaf beetles and worm-like beetle larvae feed on elm leaves which cause leaves to turn brown and prematurely fall from the tree in mid to late summer. Although elm leaf beetles cause a mess, elms seem vigorous enough to put on new sets of leaves each spring. The beetles can be controlled with the foliar sprays or systemic insecticides. Contact a Licensed Pesticide Applicator for control recommendations and services. 9). Why is topping bad for my tree? Topping trees is not an accepted practice for several reasons and is not allowed on City trees. Topping trees creates bigger problems for trees when major limbs are stubbed back. This causes a flush of growth which has very weak attachments, leading to more limb breakage. Most trees will decline within a few years and may die because the majority of the leaf canopy has been removed. Without enough leaves, trees cannot manufacture the sugars and carbohydrates needed to sustain growth. You will likely end up having to pay again to have your tree removed. If your tree has major dead limbs or simply has outgrown its space, better to have it removed and replant with a tree that will fit the site. An alternative to topping which can reduce the size of a tree within injuring the tree is called “Drop Crotching”. Certified Arborists are familiar with this method of pruning and can professionally evaluate the condition of your tree in order to suggest the right course of action. 10). Where can I find information about caring for trees in the Truckee Meadows area? You can find a host of information about proper tree care in our local area by visiting the Truckee Meadows Community Forestry Coalition Website at www.communityforestry.org. You can also call the University of Nevada Cooperative Extension at 784-4848, local nurseries, or a Certified Arborist in our area. For a list of Certified Arborists in Nevada visit the International Society of Arboriculture Website at www.isa-arbor.com. For a list of Approved Street Trees or other information call the Urban Forestry Office at 321-8371.

all is approaching rapidly and the pace and rhythms of the busy summer months are about to change. Work is slowing and gears are shifting from the hectic activities of summer landscape maintenance. That said, there is still plenty of work to be done before snow removal is the only landscape task at hand. Among other fall tasks are the planting of new trees. Not only is the cooling weather perfect for new tree planting, but garden centers and nurseries have great discounts this time of year. Along with the planting though is the issue of whether or not to support the new trees with stakes. Do they really need it? And if so, what is the proper way to do it to ensure optimum health of the tree and its root system? First, trees don’t naturally need stakes. There’s never been a case of a naturally sprouted tree requiring a stake for proper development. Of course, digging up the tree, putting it in a container or binding the roots in burlap to replant it is anything but natural. Supporting trees with stakes until established is often, but not always necessary. Furthermore, even when staking is necessary, if the stakes are left on too long or are improperly Stakes should not protrude into installed, they can cause more harm than good. the canopy where they can I like to use the analogy that stakes are like damage tender branches. a full leg cast on a person. The cast serves a Photo by Leslie Lyles purpose to aid in healing, but once the break is healed the cast comes off. If a cast were left on for years, all the muscles in ones leg would atrophy and the person would not be able to walk on their own once the cast was finally removed. Staking, in a sense, does the same thing to tree if its strength is artificially provided by restrictive stakes—the trunk and its root system are weakened. Understanding the purpose of staking trees is critical to doing it properly. Of course the primary purpose is to ensure that the tree does not topple in the wind while waiting for the roots to develop enough to support it unaided. But in order for the trunk and roots to develop properly, the tree must be allowed to sway in the wind. The movement of the tree as it sways stimulates cell growth in the trunk, therefore aiding in the development of a stronger, well tapered trunk. Additionally, root growth is stimulated as the tree moves, thus helping to provide proper anchorage for the tree—it turns a root ball, into a

root system. Improper staking actually hinders both of these processes. When staking is required, it is best to use the least restrictive support necessary. One stake placed outside the root ball on the windward side of a smaller tree that can’t stand on its own may be plenty. For larger trees that must be staked, two stakes placed perpendicular to the prevailing winds with ties set 6 to 8 inches apart will allow the trunk to sway sufficiently to stimulate root growth and strengthen the trunk without allowing the tree be blown over. So, which trees really don’t need staking when planted? The smaller the tree and root ball, the less likely it is to need support. When there is very little canopy and the root ball will hold firmly in the soil with moderate winds, staking is unnecessary. Also, the more protected from the wind the tree is, the less stakes are needed. Evergreens that have a relatively large root ball and their center of mass low to the ground, such as pines and spruces, also rarely need staking unless they are in a high wind area. In such a case, the stake ties should be attached in the bottom third of the tree, where they can lend the most support to the tree’s root system. Do not leave stakes on too long as it will not only weaken the trunk and root system, but will strangle the trunk over time. Ideally, most stakes should be removed after the first full growing season. Fall is the perfect time to remove the stakes that have lent support to trees that were installed the previous year. The best time to remove tree stakes is after the leaf drop so that there is less movement of the canopy in the wind. And since significant root growth occurs in the dormant months, stronger root growth will be further stimulated, increasing the anchorage in the soil. There are few things to remind your planting crews of when it comes to properly staking trees. It is imperative to, NEVER leave a central “nursery stake” on trees at planting. These are meant for added protection during transport and will damage the tree if left on. Stakes should always be driven into the ground outside of the root ball to prevent unnecessary root damage and they should be short enough not to rub on and damage the trees scaffold branches. Finally, make sure that the tie material is soft enough not to damage the tender bark and is not applied so tight as to cut off the vascular flow in the trunk as the tree grows. Proper staking, along with good planting and watering practices, is essential to ensuring the long term survival of new trees. After all, the goal of planting a tree is for it to thrive and survive to maturity.

» Tree Construction Zone
& Root Protection Strategies
A
By Steve Churchillo City of Reno Urban Forester Certified Arborist #RM-0475A
s an Urban Forester for the past 32 years working in New York City, Boise Idaho, and Reno, I have been directly involved in dozens of tree protection projects involving
all kinds of construction. Examples of these different types of construction-related projects affecting trees have included new playground installations and renovations, street/ curb/ gutter, and sidewalk re-construction projects,
“Remember, ‘What goes on below ground is seen above ground.’”
sewer mainline and lateral replacements, building renovations, utility installations, and site-demolition work. Although these construction type projects are different from an
engineering standpoint, tree and root protection strategies typically follow the same set of techniques and practices. The first and most important step for protecting trees during any construction project is COMMUNICATION! Before a project even begins at the planning stage, all the stake holders and their roles need to be identified. This typically includes the property owner or representative, general contractor, subcontractor(s) such as the concrete guy, electrician, architect, and landscape contractor. Others may include utility or governmental inspectors. An ISA Certified Arborist should be, but is not always, consulted. More times than not an ISA Certified Arborist is not called until after work begins and tree conflicts become apparent. The next critical step is PLANNING stage. This is the time to have the stakeholders on site to discuss the project, how it’s going to occur, who is doing what, timelines, what the desired outcomes are, and what potential conflicts exist, (i.e.: Trees in the way of equipment access, trenches near tree root zones, trees too close to structures, etc.). Projects vary in size and scope, many of which require architectural and/or engineering plans and specifications. Others may not require any written plans at all but may still require permits and following approved industry or governmental specifications such as how much base material and how thick the concrete has to be when

replacing city sidewalks. When there are trees and landscaping to be preserved in the area of construction, a Certified Arborist should be hired by the property owner to evaluate the condition of the trees and work directly with the general contractor to develop protection strategies and monitor the work to ensure trees are not damaged.

Here is a list of some basic things that should or should not be done to protect trees and roots during construction: 1.
Do an inventory, (species, quantity, size, and condition), map, and take pictures before work begins.
2.
Write a set of specifications, review w/ the contractor, and have the contractor sign and follow them.
3.
Consider potting smaller trees for replanting later and transplanting/relocating larger trees that may be in the way and could be damaged.
4.
Remove any trees that are in poor health, have structural problems that may cause tree failure, or are leaning over a structure or other targets. Prune others as needed per ANZI: Z-133 Standards.
5.
Fence off tree root protection zones to keep equipment from driving over and compacting soil within the drip-line, (area under the tree canopy). If equipment must drive over the root zone, make sure the soil is dry and spread several inches of wood chips over the entire area.
6.
Do not store any chemicals, stock pile materials, or equipment within the tree protection zone.
7.
For larger trees, place 2”x 6” inch boards vertically around the trunk and strap them together to protect the bark and cambium from being hit by equipment even though the area is fenced off.
8.
Keep any leveling, cutting, and filling of soil to a minimum where possible to protect roots and not change the natural flow of water. Be sure that water flows away from trees and does not collect at the base of trunks.
9.
Consider building retaining walls if significant grade changes are unavoidable in order to save as much of the root zone as possible.
10. Minimize any root removal as much as possible. Do not allow equipment operators to rip through areas where roots are suspected. Instead, have them lightly scrape areas and/or then hand dig around large roots to expose them. 11. Avoid having to cut roots. Look at possible bridging, posts and footings, steel plating, decking, tunneling, boring, or moving the excavation area if trenching for sprinklers or utilities services. If you must cut roots, use a hand or chain saw for a clean cut as you would do for a limb. Do not use an axe. Cut all smaller feeder roots with a sharp hand pruner or loppers. Refill the area as quickly as possible and keep moist. 12. After the project is completed, make sure that irrigation systems are working properly and trees are getting adequate water, (another subject). Compacted areas may need aeration. Look at deep root feeding using a fertilizer high in phosphorus to encourage root growth. Mulch areas to moderate soil temperatures, hold moisture, and add organic matter to soils. Continue to monitor tree health on an annual basis and treat any insects or diseases that could damage trees if you are a licensed pesticide applicator. (Check with the Nevada Department of Agriculture for licensing requirements.)
Remember, “What goes on below ground is seen above ground.” A final note about working nears trees and performing any work within City of Reno Public Rights-of-Ways: • Any work taking place in the right-of way requires an Excavation and Encroachment Permit from the City of Reno Engineering Department. Contact Travis Truhill at 334-3333 for permit information. • The City of Reno Tree Ordinance requires that a Tree Work Permit be obtained from the Urban Forester when doing any work within 10 feet of a city tree. A Tree Work Permit is also required when removing or pruning any city tree(s), or when planting a tree(s) within the right-of-way. To request an inspection prior to the issuance of a permit or to check a right-of-way, call the Urban Forester at 321-8373. The City of Reno Tree Ordinance, Approved Street Tree List, and additional tree care information for the Truckee Meadows area can be found at www.communityforestry.org.
When possible, large roots should be tunneled under rather than cut. Photo by Leslie Lyles

Protecting Plants From Winter Damage begins in the fall By Leslie Lyles, M.S. Stewardship Horticultural ISA Certified Arborist #WE-1220A
W
e’ve had a wonderful summer and beautiful mild fall, so protecting your client’s plants from winter’s damage is probably one of the last things on your mind. However, now is the time to start preparing plants to help reduce winter injury. There are three key things that can be done this fall to help keep landscape plants healthy and lessen damage from winter injury. First, there are several irrigation chores that shouldn’t be neglected. Before shutting down and draining irrigation systems, advise your clients to run their irrigation programs through several extra cycles; this can be easily done by using the ‘Manual Start’ feature on most irrigation time clocks. “Additional irrigation will Additional irrigation will build soil moisture and help sustain the plants going into winter. Also, once the build soil moisture and plants have dropped their leaves and gone dormant it is still important to water landscapes if natural precipitation is lacking. Supplemental fall and winter watering help sustain the plants is particularly important for young landscape trees and evergreens. A good rule of thumb is to deep water to a going into winter.” depth of at least eight inches if there has been less than a half inch of precipitation in a three week period. Second, avoid pruning trees and shrubs in the fall before they go dormant! I can’t stress this point enough. Pruning stimulates growth; if plants are pruned before they have been signaled that ‘winter is coming’ the plants will respond by using up energy reserves to continue growing, at a time when they should be storing energy for the winter. The new growth will inevitably be damaged when winter arrives and stored energy reserves that the plant relies on for growth in the spring will be depleted. Finally, to protect sensitive plants and evergreens, consider spraying them with an anti-transpirant such as Cloud Cover® or Wilt Proof® this fall. Anti-transpirants can be purchased at your local nursery or home improvement store and will help protect plants from winter desiccation. Plants that would benefit from extra winter protection include any newly planted evergreens, broad-leaved evergreens such as rhododendrons, laurels, euonymus and photinia, as well as delicate plants such as heavenly bamboo and roses. Remember, before you put your clients’ landscapes to rest for the winter, there are a few key chores that you can do now that will improve the health and beauty of their landscape next year. A healthy landscape will ultimately improve your client’s satisfaction with your services.
3 Key Things: 1) Irrigation Chores. 2) Avoid Pruning Before Plants Go Dormant! 3) Spray With Anti-Transpirant.

Landscape Nevada
Before pruning, ask yourself “What is the purpose of this plant in the landscape?”Remember:
Ornamental grasses and shrubs such as Caryopteris, and Rugosa rose are planted for their winter interest. Pruning now will destroy that winter beauty. Spring flowering shrubs should not be pruned until after they bloom next spring. Fall and/or winter pruning will remove the blooming wood, depriving your clients of a spectacular spring bloom.
