Weather is always all over the place in March. It’s cold. It’s hot. It’s windy. It’s dry. Do I wear shorts? Light jacket? Trees feel the same way. I know because we talk. Warm days welcome the flowers and buds, and cold evenings can shock them into freezing. It is most visible on fruit trees but Pistache, Redbud, Raywood Ash, Vitex, Desert Willow, to mention a few, can really struggle.
Whitewash can help the trees deflect the warm sun, so the cold is not so shocking. Whitewash is white latex paint mixed with water at a rate of 50/50. Now is the time to whitewash.
If your fruit tree freezes, you can possibly lose your fruit. My Apricot is fully flowered. I plan to place a 100-watt lamp under my tree to keep my tree warm and cozy during the crisp mornings.
• Old fashioned Christmas lights will keep your tree nice, and toasty as will placing a 100-watt beam lamp under your tree.
• Soaking you tree the day before an expected freeze will help. The sun warms the soil, and the heat is dissipated at night.
• If your tree is small enough, you can cover it with a sheet or tarp.
Mulch was the big discussion at the most recent Tree Conference. A professor from WSU gave an interesting talk. Ground covers should, among other things, help to conserve soil moisture, reduce compaction, moderate soil temperature, enhance plant growth, enhance beneficial soil organisms, control pests to reduce pesticide use.
• Layers of cardboard or plastic below the surface with soil on top is TERRIBLE. Besides suffocating trees, cardboard is treated with chemical to help them stay waterproof and plastic has been found to have toxic properties as well. I often see these in vegetable beds.
• There is rubber mulch, cut and colored to look like wood chips or just pieces of tire that people are using, sometimes under a swing set or in other areas of the yard. While these last, God only knows what it is does not enrich the soil. In fact, I am leery of any synthetic. Further, these retain heat. We sometimes see the little rubber mats around trees. These synthetics allegedly hold moisture, but they also create a habitat for bugs that are not good.
• Wood bark and pecan shells are also very popular. Bark and shells both had the same task in life; to keep moisture out. They are both hydrophobic meaning they do not help the landscape retain moisture.
• The Professor deduced that WOOD CHIPS are the best mulch. As they decompose, they leave the environment richer than when they got there. They are available, inexpensive, retain moisture, provide nutrients, easy to replace as they decompose, and they smother weeds while allowing trees and shrubs to breathe and grow. Have I mentioned …
