ell, spring is behind us, and what a spring it was. From the weather to the sales, it seemed to be a great season for everyone. It seemed, like all spring seasons in the nursery industry, that it went by too fast, but by all accounts, plants were becoming more and more scarce, regardless. With plants in short supply, I think we're all looking forward to a long and productive growing season. Let’s keep our fingers crossed that the weather cooperates and that we are all able to refresh and restock.

With the sudden increase in business after what were a few down years, I believe everyone is just trying to keep up with demand these days. I would encourage all our members to work together to help tackle the demand for trees together. Here within the TNLA, we have a very diverse membership base, and I'm sure you can find what you're looking for. As every nurseryman and landscaper can attest, no single grower can supply everything, and cooperation helps everyone.

As we dive into the summer, it is important to turn our attention to the Tennessee Green Industry Expo. This year, the Expo will be held on October 5–6 and will once again feature the same type of social events that were held last year, along with a great forum to meet and network with potential customers. We here at the TNLA take pride in creating a great environment that lets clients get to know you and your business, and the TNGIE is an ideal tool for both new and established businesses. Plan on attending and inviting potential customers to come out and see what your business is all about. Booth space is limited, so reserve yours before they are all spoken for.

In closing, I would like to wish all our membership a great summer and productive growing season. I look forward to speaking with you all at the TNGIE. Know that we here at the TNLA are always available to help our members with whatever issues you may have.

By Susan Hamilton, Ed.D., Director of the UT Gardens; Beth Willis, Trials Coordinator; James Newburn, Assistant Director; Holly Jones, Kitchen Garden Manager; and Jason Reeves, Curator of the Jackson UT Gardens, The University of Tennessee

REMARKABLE ROSES Dream Come True™ grandiflora rose One of the most stunning roses because of the pale-yellow bloom that is edged with a ruby-red blush. This rose develops huge flowers atop long stems.

Firefighter® hybrid tea Honoring firefighters is especially poignant for us in Tennessee this year. This beautiful deep-red hybrid tea was the first sponsorship rose of the “Remember Me” garden fund, a program to honor and raise funds for 9/11 victims. An added bonus is the beautiful fragrance of this selection. A classic red rose with a classic rose smell.

‘Good as Gold’ hybrid tea A favorite with the Beall Family Rose Garden interns in Knoxville, this hybrid tea is as good as it gets. From the bud stage through its bloom period, this rose is outstanding. A deep peach-colored bud opens to a yellow-orange classic hybrid-tea double bloom that then fades with hints of a deep-pink blush along the petal edges.

‘Julia Child’ floribunda This was our favorite yellow rose this year. Our shrub was absolutely covered with blooms, even in the hottest part of the year. Rich, buttery yellow clusters of blooms held their color well before slowly fading.

South Africa™ Sunbelt® grandiflora A selection from the Kordes Sunbelt series that tolerates the heat and humidity of the South, this rose is a prolific bloomer with large blooms of dark golden yellow. tennessee greentimes Summer 2017

TREMENDOUS TREES & SHRUBS Acer japonicum ‘Aconitifolium’ — ‘Aconitifolium’ Full Moon Maple A dwarf, multi-stemmed shrub or small tree that typically grows slowly to 8' to 10' tall. Specimens are valued for their sculptural form and incredible fall foliage display, ranging from orange to crimson colors. Foliage requires lightly dappled shade in Tennessee. Leaves will scorch in full sun in our hot Mid-South summers.

Plants perform poorly south of USDA Plant Hardiness Zone 7, since they prefer cool summer conditions, so carefully select the site. Not suited for west Tennessee conditions. Stake the trunk for more erect growth, or leave alone for its spreading effect. Easily grown in average, mediummoisture, well-drained soil. Use as specimen plant where form and foliage color are the focal points. Landscape up-lighting will accentuate the sculptural form and brilliant fall foliage color.

Acer rubrum Redpointe® — Redpointe® Maple A rising star on the shade-tree horizon, Redpointe® Maple is tailored for today’s streetscapes and landscapes. The trees are heat resistant and vigorous growing, and they are a colorful choice for sustainable landscapes. This selection was the top performer among seedlings from in the J. Frank Schmidt & Son Co. Acer rubrumbreeding program. The tree is pest and disease resistant and is easily maintained.

It has demonstrated superior resistance to leaf chlorosis and improved resistance to anthracnose, spider mites and leaf hoppers.

Well-behaved, balanced growth eliminates the need for a lot of pruning and shaping to develop a symmetrical canopy. A straight, dominant central leader assures uniformity. Strong branch attachments with ideal angles mean that less labor is needed to develop a pyramidal street tree shape. Smaller and more refined than those of Acer xfreemanii, leaves are deep green, heat resistant and fresh looking all summer. Brilliant fall color appears early and is reliably bright red.

In the Garden

Lagerstroemia indica ‘Royalty’ — ‘Royalty’ crape myrtle This medium-sized crape myrtle growing 6' tall and 8' wide is covered with panicles of crinkly royal-purple blossoms in the summer. Green foliage turns orange-red in autumn. Dormant plants display attractive gray-brown exfoliating bark on upright stems. A nice medium-sized shrub, it’s great for use in group plantings or as a single specimen.

Cryptomeria japonica ‘Gyokuryu’ — ‘Gyokuryu’ Japanese Cedar A wonderfully mid-sized Japanese cedar that is ideal for a smaller landscape. Slowly forming a dense, irregular pyramid 5' to 10' tall and 3' to 7' wide, this is a great evergreen for use as a foundation plant, screen, mixed border or single specimen.

Distylium A relative newcomer to the landscape industry, Distylium is the result of years of trials and selective breeding in an effort to come up with worthy specimens that are evergreen, adaptable and virtually immune to the majority of common pests and diseases. A hybrid from the witchhazel family, it was developed and bred to provide selections that have growth habits and sizes that fit a wide array of landscape uses. Noted for being pest and disease resistant, as well as tolerant of both drought and wet soil, it will thrive in full sun to partial shade. Landscape uses include as evergreen hedges, foundation plantings, containers and single specimen. ‘Vintage Jade’ is one of the lowest-growing selections, to just 2' tall and 5' wide, with an arching, somewhat mounded habit. ‘Cinnamon Girl’ grows 3' tall and 5' wide; bronze foliage appearance is the main distinction that sets this selection apart. ‘Blue Cascade’ is slightly more upright than other selections, growing 3' tall and just as wide.

Lagerstroemia indica ‘Sacramento’ – ‘Sacramento’ weeping crape myrtle A compact crape myrtle, growing to just 2' to 3' tall and just as wide. Its mounding, weeping habit makes it great as a ground cover or as a decorative container plant.

It can also be used for border plantings and in mass. The rose-pink clusters of blooms smother this super-compact selection and are on display from late spring through summer. New growth pinched during the growing season will increase branch numbers and inflorescence production. Deadheading spent flowers during the season will encourage a second flush of flowers!

Liquidambar styraciflua Happidaze™ (syn. ‘Hapdell’) — Happidaze American Sweetgum

Sweetgum is a beautiful tree, but most homeowners won’t grow it because of its messy fruits. Thanks to this fruitless selection, messy “gumballs” are no longer a problem. This is a beautiful tree, too; the leaves turn lovely shades of burgundy and maroon in fall, and mature specimens develop oval to rounded crowns with age.

Grows 60' to 80' tall and 40' to 60' wide.

Plants are intolerant of shade, yet are easily grown in average, medium moisture, well-drained soils in full sun. Prefers deep, moist, fertile soils, but seems to tolerate a wide variety of soils.

Viburnum nudum ‘Brandywine’ — ‘Brandywine’ Possumhaw Viburnum ‘Brandywine’ is a deciduous viburnum cultivar with glossy foliage that turns stunningly dark maroon-red in fall. White flowers in spring become clusters of vivid pink and blue berries in fall. It will have a good berry set without a pollinator plant, but adding cultivar ‘Winterthur’ will really amp up the number of berries. Has good deer resistance and attracts birds. Grows 6' tall.

Viburnum plicatum var. tomentosum ‘Summer Snowflake’ – ‘Summer Snowflake’ Doublefile Viburnum A deciduous viburnum that is perfect for adding seasonal interest in the landscape.

Use for spring flower, late summer red berries and fall foliage. It’s perfect in a mixed border or a single specimen in the landscape. Its upright growth habit matures to 5' to 8' tall. White lacecap-like flowers bloom in spring (late April–May), but they continue to bloom sporadically through summer (hence the cultivar name) and sometimes into early fall. Red berries appear in late summer. Fruit, a few flowers and autumn foliage color may all be simultaneously present in early fall, making quite a show in the landscape.

The dark-green leaves turn burgundy-red to purplish-red in fall.

INCREDIBLE EDIBLES

Viburnum lantana ‘Variegatum’— Variegated Lantana Viburnum Dark-green leaves are flecked with light green, chartreuse and white that add depth and interest to this slow-growing, 5' to 8' shrub. It does best in afternoon or full shade to keep variegation prominent with no burning. It tolerates dry conditions.

Fruit forms in clusters and ripens from red to black, reminiscent of lantana, which gives it its species name.

Blackberry ‘Triple Crown’, Rubus fruticosus ‘Triple Crown’ This thornless variety was released in 1997 through a joint breeding program with USDA-Beltsville and the Pacific West Agricultural Research Service. It has become a standard for growers due to its outstanding flavor, productivity and vigor. It has proven to be sweeter and more productive than the other three varieties grown in our kitchen garden over the past four years.

Garlic Chives ‘Geisha’, Allium tuberosum ‘Geisha’ With larger flower heads and wider leaves, this 2015 AAS-winning variety outperformed the standard garlic chives in the UT kitchen garden this year.

Flowers appear towards the end of the season and are hugely popular with honeybees. C

Tree Health After the 2016 Drought

By Wayne Clatterbuck, Ph.D., Professor, Silviculture and Forest Management, UT Forestry, Wildlife and Fisheries

A

tree strives to maintain equilibrium within its environment. Any time the tree is not in equilibrium, the tree is stressed and must spend extra energy to survive. Many trees can become stressed by prolonged periods of hot, dry weather that result in drought. The term “drought� denotes a period without precipitation during which the water content of the soil is reduced to such an extent that trees suffer from lack of water. Water deficits in a tree are formed when transpiration (the process by which leaves emit moisture) exceeds the water supply available to the leaf. Trees need a drink of water, too!

Although drought conditions are common in southeastern landscapes, the absence of rainfall in east Tennessee and other adjacent areas during the late summer

and fall of 2016 was unusual. Knoxville has averaged about 50" of precipitation a year for the last 6 years. In 2016, total rainfall was less at 42", but the temporal distribution of the rainfall fluctuated. From August 22 through November 28 (71 days), rainfall accumulation was only 2", less than 1" per month. The Chattanooga area had even less rain. Knoxville then received 5.5" in two days on November 29 and 30, with almost 7" following in December. These late-season rainfall events allowed annual precipitation to approach the normal range for the year, even though the monthly rainfall pattern was skewed.

In the future, conditions like we experienced in Tennessee during 2016 are expected to become more common. What happens when environmental impacts are

compounded with greater likelihood of water shortages and usage restrictions that may be enacted in many urban areas?

Prohibitions on city-water use for irrigating landscape trees can mean that planting trees that are more tolerant to drought conditions will offer the best long-term solution to a healthier, low-maintenance landscape.

Trees often become long-term investments in landscape sustainability and ecosystem services. What can be done to make landscapes more resistant to drought or to protect landscape tree resources? One good approach is to select trees that use water efficiently, particularly if sections of landscapes do not receive frequent watering or irrigation.

In the short-term, drought conditions disrupt food production (carbohydrates) since photosynthesis is reduced and

Pictured above: The late-season drought in east TN in 2016 caused many leaves on the branches and twigs of white oak trees to die and turn brown on branches without the leaves abscising or shedding. This photo (taken in early April 2017) shows those dead leaves from the previous year still on the trees while the buds are beginning to enlarge and new leaves emerge. (Photo credit W.K.

carbohydrate distribution becomes limited.

As trees try to conserve their moisture resources, visual symptoms of drought stress include wilted leaves, premature defoliation and discolored or brown leaves.

Other physiological processes also change, like timing and rate of flower and fruit production. Drought often compounds other pre-existing stresses such as mechanical injuries (wounding), chemical injuries (pesticides/herbicides) and tree decline due to age and pests (insects and disease).

Drought leads to decreased rates of diameter and height growth with most of the variation in tree growth associated with water supply problems. Sustained drought can also lead to poor resistance to other stressors. Drought stressed trees 14

tennessee greentimes Summer 2017

often die during the next growing season.

Trees try to re-leaf or re-foliate with reduced leaf size and sparse density crowns, further depleting any energy reserves remaining from the previous drought year.

Once those reserves are exhausted, the tree succumbs. Older trees that are nearing the end of their lifecycle, as well as newly planted, young trees that have limited energy reserves, are the most susceptible.

Although there is not an ideal droughtresistant tree for every landscape, many trees that have adapted drought-resistant features — like smaller leaf size, more leaf surface wax, fewer leaf stomates and vase-shaped and multi-layered crown forms — are more capable of tolerating dry conditions. When seeking trees that

are most likely to use water efficiently, consider that: • Native trees are better adapted to local soil, moisture, climate and pest conditions than non-native trees.

• Trees with small leaves (linden, elm, willow oak and cherry) are more easily cooled and have better water-use efficiency than trees with larger leaves (sycamore, cottonwood, basswood, yellow poplar/tulip poplar, sweetgum and redbud).

• Upland species (many oaks, pines, elms, beech and hickories) are usually more drought-resistant than bottomland, riparian species (walnut, box elder, river birch, red and silver maples, black gum, southern red and

pin oak, bald cypress and hackberry).

• Early successional species, those that colonize old fields and disturbed sites (pines, black locust, elms), use water more effectively than late successional species (sugar maple, oak and beech).

• Trees with deep, upright crowns are more effective in water use than those with flat, wide-spreading crowns.

• Trees with multi-layered crowns having many branches and leaf layers (oak, ash, gum and hickory) are more water efficient than those trees with leaf canopies that concentrate leaves in single layers along the outer edge of the crown (beech, dogwood, sourwood, redbud and magnolia).

• Drought-tolerant plants usually have thick bark and leaf waxes (cuticle), efficient stomatal control and extensive root systems.

Some landscape tree options, including many tree species native to Tennessee, are not particularly drought-tolerant. For example, black cherry, basswood, beech, birch, buckeye, cottonwood, dogwood, sassafras, sugar maple, sycamore and yellow poplar or tulip poplar trees respond to drought by shedding leaves prematurely or wilting. These trees can benefit by being planted in locations where they are only partially exposed to direct sunlight and prevailing winds during the day. Limiting exposure to direct sunlight in open areas, for example, provides some drought relief.

Shade-tolerant trees are more tolerant to drought than shade-intolerant trees.

Symptoms that trees need water are leaf curling, leaf discoloration and browning, and leaf detachment. Trees should be watered once or twice a week during the growing season if there is limited rainfall. A few high-volume waterings are more beneficial than many light and shallow waterings. Light waterings encourage shallow rooting, which can lead to more stress during lengthy droughts.

Light watering also tends to benefit the fibrous root systems of turf near the surface of the soil rather than the root systems of trees. Greater volume and deeper watering at less frequent intervals are recommended during droughts for trees.

Refer to the following UT Extension publications and web addresses for more

information on trees with drought-tolerant attributes, why trees become stressed and die, and recommendations for watering trees.

Irrigation Success Story

the switch to drip

saved water and fertilizer

J.

Frank Schmidt and Son Nursery relied exclusively on overhead irrigation to provide water to their field-grown liners. They hand-moved lines from field to field to permanent risers.

Between the inherent inefficiency of overhead irrigation systems, minimum wage increases, overtime needed by the irrigation crew, safety concerns from moving heavy pipes with wet, slippery surfaces and water-quality decline in certain wells, it became logical to consider changing to drip irrigation.

So, Sam Doane, Production Horticulturist at J. Frank Schmidt and Son Co., prepared a labor-savings analysis for the owners that showed the return on investment for the infrastructure expense was two years, what previously required 16 people could now be done by 3 workers, and, by the end of the third year, water use would decrease by 30%!

Sam began converting the Canby, OR, farm to drip irrigation. By switching to subsurface drip, Sam noticed that the application was much more efficient. The

J. Frank Schmidt and Son Nursery next step was to develop an irrigation program suited to this more efficient delivery. Sam worked with Rich Regan at Oregon State University to use soil moisture sensors that provide real-time measurements and to develop crop coefficients in order to determine how much water the plants needed.

They currently use 10-HS and GS1 soil moisture sensors with Em50 data loggers (Decagon Devices, Inc.) as the basis for irrigation decision-making. By using several probes at each location, this equipment provides volumetric water content (VWC) of the soil at different depths.

Instead of using the numerical values for VWC, Sam has found that monitoring trends is far easier and just as reliable. To use the sensor readings as absolute values (irrigate when the soil reaches a certain VWC), each sensor would need to be calibrated to the unique physical properties of the soil. By using relative comparisons over time, Sam is able to see when peak water uptake occurs (the probe readings are going from higher to lower VWC over

Previously J. Frank Schmidt and Son Nursery used solid-set irrigation that had to be moved from field to field throughout the season and installed in each new location. Photo by Sam Doane.

time) at each depth and when water uptake slows (probe readings are relatively stable over time). Decreasing water uptake implies that the soil is drying (or that the plant is done growing or the root has died) and signals the need for irrigation.

Previously, J. Frank Schmidt and Son had switched from broadcast to banded fertilizer applications to conserve fertilizer. While converting to drip irrigation presented a challenge for watering in a granular fertilizer application, it opened the door to a new possibility. Sam could deliver fertilizer right to the root zone by injecting fertilizer through the drip irrigation system. By simultaneously irrigating and fertilizing, J. Frank Schmidt and Son Nursery lowered overall fertilizer use by 30%! Sam calculated that the return on investment of adopting fertigation was less than a year!

Success story provided by Sam Doane, J. Frank Schmidt and Son Co. For more information, see http://c.ymcdn. com/sites/www.oan.org/resource/resmgr/ imported/pdf/JFankCaseStudy.pdf. C

The nursery adopted a battery-powered soil moisture sensor system to schedule irrigation and fertigation applications delivered by drip tape, which stays in place the duration of the crop. Photo by Sam Doane.
