Extreme weather events and changing climate conditions result in chronic stress to our woody plants. In many areas, we have seen decline and death of even well-established mature trees. Here are suggestions to promote the health of trees and shrubs, and to protect them from temperature extremes.
Apply and maintain a 2- to 4-inch layer of organic mulch at the base of woody plants, extending out to the drip line if possible. Wood chips are one of the best materials to use. The combination of leaves, twigs, bark and wood is similar to the natural mulch found in a forest setting. This layer of mulch allows water penetration and decreases evaporation, and protects roots from extreme temperature changes. Mulch should be left to decompose in place rather than removing and replacing with new mulch each year.
Providing water during drought is very important. Trees and shrubs, especially evergreens, are at a great disadvantage going into the winter months, suffering drought stress. Be sure to continue irrigation until cold temperatures arrive.
Ask your Bartlett Arborist Representative to sample your soil for nutrient content and pH level. Fertilize only if your soils are nutrient deficient. Adjusting soil pH may be necessary to improve availability of some nutrients. Multiple treatments may be needed to make adjustments in soil pH. Fall is the perfect time to begin these services.
