It is perhaps the best times to plant trees since they will have ample time to start getting established prior to the heat of Summer. It's even a good time for an application of certain tree fertilizer formulas to grow roots and kick start the new growth in the Spring.
Mostly, it is a great time to prune and trim trees. Here are some key reasons why:
1) Low stress - Since both deciduous and evergreen trees are in their dormant period, removing limbs has less impact on the near-term and long-term health of the tree. In addition, more frequent rainfall and cooler temperatures means the soil holds a greater amount of moisture for the roots which is like a protective blanket for the tree. Winter is like a general anesthetic for the tree when it is being "operated on." When the tree comes out of its sleep in Spring the tree has already started its healing process from any cutting that has been done.
2) High visibility - For deciduous trees, their branch structure becomes quite visible and structural issues can be more clearly identified and addressed. Overlapping or rubbing limbs can be removed before the problems become more significant. Areas where the canopy needs thinning become readily apparent. Mistletoe can be identified for removal in Cedar Elms, Hackberries, Oaks, and Bois d'Arcs.
3) Low risk - Cutting trees makes them more succeptible to a variety of pests like insects and disease. During Winter months insects are also dormant and not actively seeking out new territory to infest. Beetles, aphids, caterpillars, etc are sleeping through the winter cold. Fungal diseases such as Oak Wilt and Cotton Root Rot have stopped their life cycles temorarily as temperatures drop. Cuts made in Winter months are far less likely to become conduits for pests to infest your trees.
I know that this topic begs the question, "Why would I want to have my trees pruned in the Summer?" The answer is this -Trees can be safely pruned any time of year by tree professional taking the appropriate precautions. Such procautions would include sterilizing equipment, painting tree cuts, and application of water and nutrients.
