Winter is here and most of the deciduous trees have shed their leaves. The early January freeze reminded us what a winter is supposed to be like. Trees have an appreciation for a good freeze. For the first time in a couple of years, we have had a freeze that last more than a couple days. This slows down the biological processes of trees and allows them to go into full dormancy. As arborist, we love this time of year as well. We can better see structural defects, mistletoe and perform more invasive tree surgery that we have been holding off, until now. The winter is the perfect time to consider tree pruning and other ways to care for your trees.
Structural Tree Pruning
During the dormant season, we are better able to see and correct structural defects in trees. We have trained our arborist and technicians on how to identify structural defects such as: co-dominant stems, included bark, and poor branch attachments. These defects may lead to tree failures if not corrected.
Mistletoe is a parasitic plant that is often identified in Cedar Elms, Hackberries, and many other species of trees. While the trees are dormant, we suggest removing mistletoe prior to blooming to prevent further spread.
The window for pruning oaks is closing soon. We recommend pruning your oaks prior to the middle of February and after the middle of June in the Dallas-Fort Worth area. This is to prevent an established disease known as Oak Wilt.
Supplemental Support Systems in Trees
Since it is easier to see structural defects throughout the tree canopy in the winter, it is the best time to install a supplemental support system. This may include extra-heavy strength cables, bracing rods, or even props for very old, low branching trees. Support systems help trees withstand the high winds, ice and rain that occur throughout the year. Not all trees need supplemental support, but this should be determined by a trained arborist.
Winter Dormant Oil for Trees
Applying an organic winter dormant oil is an environmentally friendly way to reduce insect and mite populations in your garden. Dormant oils have been used for many years as a proactive method to reduce pest populations. These oils suffocate overwintering eggs of destructive pest. The eggs are laid in the cracks and crevices of your trees and shrubs. In the spring they emerge and feed on succulent plant tissue. This treatment greatly reduces plant injury caused by foliar and stem feeding pest.
