Neil Sperry 2 1 3 2 Texas A&M AgriLife Extension Service – Collin County Volume 7, Issue 1 Snow and Ice Damage to Trees sleet sticks to wet limbs and foliage, causing the rain to freeze. If you already have snow buildup on limbs and leaves, the sleet adds to the weight. A Certified Arborist’s View on the Recent Storm by Steve Houser Editor’s Note: This article about the December ice storm is reprinted with the author’s permission. It originally appeared on December 12, 2013 in Neil Sperry’s e-Gardens. It is the time of year when all good arborists start to worry about the ice and snow damage to our trees. The weather events of the past week justify those concerns. Often times, we are so excited to actually get a little snow, we overlook the potential damage that can occur. The dramatic change of a little snow is welcome, until it just keeps coming down. Joy quickly turns to fear as your live oak snaps a limb — and it falls on your favorite holly. If you were a tree, your biggest concern beyond the effects of humans, would be the effects of Mother Nature. Deciduous trees that have not dropped their leaves have a difficult time supporting the weight of ice and snow accumulations, and are likely to suffer broken limbs. Photo by Bill Seaman Photo by Steve Houser If your landscape has only deciduous trees, those that lose their leaves, you may think you have no worries. However, the recent ice storm tells us otherwise. Enough ice can build up on limbs without foliage to cause breakage. A half-inch of ice on a limb will dramatically increase the weight load on limbs, trunks and roots, leading to structural failure. Although we had great fall color and warm fall weather, the mild weather slowed the drop of leaves. As a result, trees that did not lose their leaves had more surface area for the ice or snow buildup, increasing the odds of breakage. The same situation applies to some deciduous trees, such as Texas red oak and blackjack oak, which go dormant but may tend to hold their leaves all winter. Although the tree is dormant, it is much more susceptible to damage. Sleet, following cold rain, is also a problem because the The best defense against ice and snow damage is to work diligently now to minimize any future impact. Extremely severe weather can cause the loss of most, if not all, trees in an area, regardless of any efforts to reduce the damage before it occurs. Damage from less severe weather can be lessened by inspecting trees for weak branching habit that is likely to fail. In some cases, weak areas can be reinforced with cables or bracing rods. Ideally, poor branching structures — tight V-shaped forks or attachments, should be removed when the tree is small. Doing so eliminates the risk of that fork splitting as the tree matures. For trees with spreading canopies, selective end-weight reduction pruning can significantly reduce damage from heavy snows & ice. Photo by Bill Seaman — continued on page 4 3 4 6 5 Texas A&M AgriLife Extension Service – Collin County Volume 7, Issue 1 Snow and Ice Damage to Trees (continued from page 3) Beyond resolving weak branching habit, be aware that longer limbs in trees tend to have broad, spreading canopies, should have the end-weight reduced to lessen the surface area exposed to ice, snow, sleet or high winds. Professional tree climbers are trained to climb out to the ends of the limbs to reduce the weight. Bur oak trees have stout limbs and a branching habit that supports the load of ice and snow with minimal damage. Photo by Bill Seaman Arborists also consider the strength of the wood for each species of tree when determining corrective actions for structural deficiencies. An oak will typically have a strong wood, whereas a maple will be weaker-wooded and more likely to break. Ice, sleet, and snow buildup can cause tree limbs to bow to a great degree without breaking. The affected branches will return to their previous position once the ice and snow melts. In some situations, however, the limb can contain internal cracks that are difficult to see, or the vascular system may be damaged to the point that the limb permanently retains a bent shape. Once you have an ice or snow problem, little can be done until the weight load melts. Low limbs on larger trees or smaller ornamental trees can sometimes be braced with wood or other materials. However, doing so can put someone at great risk should the tree or limb fail during the process of propping it up. Once the severe weather event is over, standard tree care practices should resume. This includes removing broken and damaged limbs by making proper pruning cuts, evaluating any splits or cracks in trunks or branches, inspecting and adjusting cables or bracing rods on mature trees, and adjusting staking hardware on newly planted trees. The snow and ice can be beautiful, but when it comes to the risk it may present to your trees, the adage “Be careful what you wish for” applies.

Collin County Master Gardeners present the 11th Annual Plant Sale Saturday, April 12, 2014 at the Texas A&M AgriLife Research and Extension Center Pavilion Building 17360 Coit Road, Dallas, Texas 75252 Watch the Garden Wise Gazette and our website ccmgatx.org for details. 4 1 2 3 Texas A&M AgriLife Extension Service – Collin County Volume 7, Issue 1 Vegetable Garden Takes Root at Myers Park article by Jamie Upson, Collin County Master Gardener photo courtesy of CCMGA This spring, the Earth-Kind ® up at Myers Park in McKinney. The research garden is designed to determine if EarthKind® principles by measuring the impact on soil fertility from decomposing mulches during the growing season. The Vegetable Research Garden is sustainable through and through. But what, exactly, constitutes sustainable gardening? Master Gardeners employed Integrated Pest Management techniques, or “squishing every bug we see and crossing our fingers.” They pulled weeds regularly and used no synthetic fertilizers. The spring garden contained twelve types of vegetables, including four tomato varieties, cantaloupe, peppers, squash, eggplant, cucumbers and zucchini. The plants lived in six raised beds constructed of yellow pine planks. The boxes measured forty-eight feet long by three feet wide and were tilled to a depth of eight to ten inches. Four to six inches of fully aged, vegetative compost was tilled into each bed. Plants were watered weekly using a drip irrigation system. Three types of mulch were used in this trial: partially composted hardwood mulch, leaf mulch and regular hardwood mulch. Soil fertility was tested at the start of the trial prior to the addition of compost, immediately after compost and at the end of the growing season. Why rely on a “compost and mulch only” approach for fertilization? We know that microorganisms decompose or “breakdown” organic matter to obtain the nitrogen and other essential nutrients they require to live and grow. Garden plant materials respond to the essential plant nutrients released during the decomposition process the same way they respond to the addition of fertilizers. Organic mulches not only help conserve soil moisture, suppress weed growth and maintain uniform soil temperature; they can also be a source of natural plant nutrients by releasing nitrogen, phosphorous, and other essential plant nutrients into the soil. What about the results? Despite heavy spring winds, extreme summer temperatures and a swarm of grasshoppers and squash bugs, the garden thrived. Over 700 pounds of vegetables were harvested and donated to local food pantries. Staff at Allen Community Outreach was especially grateful for the fresh produce as they receive mostly processed food donations and yet, want to teach their clients about the importance of including fresh fruits and vegetables in their diets. What does the Vegetable Research Garden's future hold? To continue this effort, and to support the increased interest in our community in sustainable vegetable gardening, Collin County Master Gardeners are building a potager style demonstration garden. A potager garden is the French counterpart to the English kitchen garden, but with an emphasis on growing vegetables. The potager will have intermingled vegetables, fruits, flowers, and herbs. Master Gardeners envision the garden serving as a hands-on space for outreach and teaching in the future — a place for the community to smell, touch and occasionally taste. It’s therapeutic to be around growing things, and in addition, there’s a lot of science going on in a small amount of space. CCMGA looks forward to sharing this with the community. 5 1 2 3 Texas A&M AgriLife Extension Service – Collin County Volume 7, Issue 1 Image courtesy of Simon Howden/FreeDigitalPhotos.net Garden Checklist for January and February Plan: • • Make flower and vegetable garden plans now before the rush of spring planting. Time spent in armchair gardening before the fireplace will pay off in improved plant selection. Besides, it is fun to page through the garden catalogs. Select and order gladiolus corms for February/March planting. Plant at two-week intervals to prolong flowering period. Fertilize: • • Prepare: • Prepare beds and garden area for spring planting. Plant: • • • Now is an excellent time to transplant mature or established trees and shrubs while they are dormant. Sow seeds in flats or containers to get a jump on plant growth before hot weather arrives. Petunias, begonias, and impatiens should be sown in early January. Warm temperature plants, such as tomatoes, peppers, marigolds, and periwinkles, should be sown indoors in late January or early February. When buying plants, the biggest is not always the best, especially when dealing with bare-root plants. The medium to small sizes (4 to 6 feet) are usually faster to become established and more effective in the landscape than the large sizes. Apply a light application of fertilizer to established pansy plantings. Use one-half pound of ammonium sulfate per 100 square feet of bed area. Repeat the application every 4 to 6 weeks, depending on rainfall. Dried blood meal is also an excellent source of fertilizer for pansies. Don't fertilize newly set out trees or shrubs until after they have started to grow, and then only very lightly the first year. Prune: • When pruning shrubs, first prune out any dead or damaged branches; then thin out by removing about one-third of the canes or stems at ground level, removing the oldest canes only; and last, shape the rest of the plant, but do not cut everything back to the same height. Roses: • • Hold off on pruning bush roses until February or early March. Use good shears that will make clean cuts. Remove dead, dying, and weak canes. Leave 4 to 8 healthy canes, and remove approximately one-half of the top growth and height of the plant. Now is an excellent time to select and plant container-grown roses to fill in those bare spots in your rose garden. • Climbing roses should be trained but not pruned. Weave long canes through openings in trellises or arbors and tie them with jute twine or plastic/wire plant ties. Securing canes now prevents damage from winter winds, and contributes toward a more refined look to the garden when roses are blooming. Wait until after the spring flowering period to prune climbing or onceblooming shrub roses. Other Tasks: • • • Check junipers and other narrowleaf evergreens for bagworm pouches. The insect eggs overwinter in the pouch, and start the cycle again by emerging in the spring to begin feeding on the foliage. Hand removal and burning of the pouches are ways of reducing the potential damage next spring. The life of the plant received as a Christmas gift can be prolonged with proper care. Keep the soil moist, but provide drainage so that excess moisture can flow from the pot. Keep the plant out of the range of heating ducts and away from heating units. Keep in a cool room at night, preferably at 60 to 65 degrees F. Water foliage plants as well as other containerized plants only when needed and not by the calendar. 6 1 2 Texas A&M AgriLife Extension Service – Collin County Volume 7, Issue 1 The International Award Winning Research & Demonstration Gardens at Myers Park & Event Center – McKinney, Texas photos courtesy of: the Collin County Master Gardeners Association Upcoming Events Spring into Vegetable Gardening Saturday, January 25, 2014 8:30 am – 12:30 pm The Collin County Master Gardeners will present a program on spring vegetable gardening on Saturday, January 25, 2014.

Because Texas is so large, there are several dates of the last freeze date (LFD) says Brent McRoberts of Texas A&M University. “In the panhandle area, the LFD is not until early April because it is not uncommon for Amarillo and other areas to receive snowfall as late as May,” McRoberts, explains. “And in the Rio Grande Valley, it almost never freezes so there really isn’t a LFD to speak of. Much of Central Texas and a large part of the state have an LFD of March 12-15. But remember, these are average dates, and a freeze can certainly happen much later.” Has the LFD date remained the same over the past century? County Extension Agent: Greg Church, Ph.D. Email: [email protected] Garden Wise Editor: Bonnie Landon Email: [email protected] Collin County Master Gardeners Association http://ccmgatx.org http://collin-tx.tamu.edu A quick answer is that it is probably occurring earlier, McRoberts says. “It’s been proven the Earth is getting warmer over the past 100 years, so that means that the last freeze probably occurs earlier and it starts getting warmer sooner, say in February or March,” McRoberts adds. “If a freeze should occur later than usual — near the end of March or early April — it can really do some serious damage to trees and plants that are starting to bud and bloom.” The above information was excerpted from Weather Whys in the tamuTimes. Weather Whys is a service of the Department of Atmospheric Sciences at Texas A&M University. An excellent website for learning the first and last freeze dates for North Texas is: http://www.srh.noaa.gov According to Dr. Greg Church, Collin County Horticulture Extension Agent, “This is interesting information about the first and the last freeze. Good information . . . relevant for landscaping, gardening, fruit crops and agriculture.” You’ll want to check the website for the average last freeze date for our Dallas/Fort Worth area when you start planning for your spring gardens.
