Are Your Oaks Looking Bad? They are Still Recovering from the Freeze!

May 06, 2021

The unprecedented winter weather in February 2021 will have a lasting effect on North Texas. Many trees and plants have already failed to come back from the freezing temperatures and had to be removed. Others may be showing signs of new growth, but are still struggling. The Texas A&M Forest Service and other experts have reiterated the need to care for freeze-damaged and stressed trees to give them the best chance of recovering.

WHAT CAN YOU DO? KEEP WAITING!

Freeze-stressed trees, especially oaks, may be putting out some new leaves, but are much less vigorous than in previous years.

Continue to monitor them, and do what you can to alleviate stress.
Water your stressed trees properly, and make sure not to flood the roots with overwatering.
Avoid preventative insecticide or fungicide treatments; treat only those pests that are currently active in the tree.

RECOVERY WILL TAKE A LONG TIME

Whatever the progress of your tree’s recovery, it will take months and possibly years to regain the health it had before the winter storms.

If a tree has shown no signs of new growth by July, it will likely never recover.
Trees with sparse growth may be able to leaf out normally in a year or two, so consider waiting to remove.
As always, contact an ISA Certified Arborist to evaluate your trees’ progress and make recommendations for care.
