When Is The Best Time To Trim Trees? - Texas Tree Surgeons

Why is it important to use a company with certified arborists to trim your tree?

Every tree is different. Two trees of the same species planted next to each other may still react differently to their surroundings. Having an ISA Certified Arborist examine your trees before trimming is crucial to ensuring proper care. In a yard with different tree species, there may be a range of trimming needs. A certified arborist can assess each individual tree to make the best recommendations for trimming, taking into account species, environment, disease or pest activity, and the tree’s natural life cycle. Improper trimming at the wrong time of year can cause a tree’s health to decline substantially. A certified arborist’s knowledge of tree biology and trimming best practices leads to the best trimming recommendations for your trees.

Is there a best time to trim a particular species of tree?

While it is generally best for all trees to be trimmed in the fall and winter, it is important to be aware of issues particular to a given species.

Oaks:

• The best time to trim oak trees in Texas is in the fall and winter.
  • It is critical to avoid trimming during oak wilt season (February-July) if at all possible.
  • Live oaks typically do a leaf exchange in late winter so it is better to trim them in late fall or early winter.
• Dead and broken branches can be removed at any time.

Maples:

• The best time to trim maples is fall and winter.
  • Pruning in the early spring can lead to sap leaking from the pruning cuts.
  • Maple trees are one of the few trees that have fall color in Texas so pruning after the leaf drop is usually preferred.

Elms:

• Elms are hardy and native to Texas. They are typically the first to get their leaves and the first to lose their leaves. Trimming elms in the fall and in the winter is best to avoid sap leaking.
• Elms are prone to rotting where large pruning cuts are made or poor puts are made so conservative trimming is best.
• In the parts of North America where Dutch elm disease is present, elms should be trimmed before March.

Crape Myrtles:

• Crepe Myrtles produce flowers on each year’s new growth.
  • Trimming in the fall leads to more blossoms in the spring.
  • Trimming in the late spring will reduce the number of flowers the following year.
• For the health of the crape myrtle, the best time to trim is winter.
  • Topping crape myrtles is never a good practice.
