Helping Damaged Trees after an Ice Storm
If your oak trees were damaged by a recent ice storm, you may be wondering what you should (and shouldn’t) do to clean up the damage while also protecting them from oak wilt.
While painting fresh wounds on oak trees is important to prevent the spread of oak wilt, wounds that were caused by the ice storm are no longer fresh. In cold conditions, trees quickly stop exuding sap and sap-feeding beetles are not active, so it is unlikely that oak wilt will spread as a result of an initial ice storm event.
- Broken limbs on roofs, fences or other structures
- Limbs blocking driveways and travel lanes
- Hanging limbs that could cause personal or property damage if they fall
Prune safely within your ability and DO NOT remove limbs on or near power lines. For work you cannot complete safely or that is beyond your ability, find a Certified Arborist.
Be sure to immediately paint any new wounds on oak trees that are created during cleanup using wound dressing or latex paint. Immediately means make one cut then paint it before making the next cut. Clean all pruning tools with a 10% bleach solution or Lysol before pruning a different tree.
Additional cosmetic pruning of oaks should be delayed until summer, once the threat of oak wilt spread has diminished. Avoid pruning oaks February through June! Any trees that are not oaks can be pruned at any time and painting the wounds is not necessary.
When disposing of debris, burning should be delayed until spring green-up when wildfire danger is reduced. If debris must be disposed of immediately, a chipper is recommended.
