As an admitted plant geek, it hurts my heart to look around at the battered landscape we are left with after Hurricane Michael bombarded us with unforgiving winds. At the same time, I am uplifted by all the emails and online threads I see asking “How can I save my tree?” Every situation is different, but here are some quick tips to help you assess and mitigate damage to your landscape trees.
- Is this a newly planted tree (less than one year)? If so, it is a good candidate to push or pull upright and stake for stability.
- How big is the tree? Trees that are 4 inches or less in diameter are more likely to have the ability to regenerate a stable root system than larger trees. Diameter of 4-8 inches could be staked but may become a hazard later. It is not recommended that trees greater than 8 inch diameter be stood up because the risk of instability is high.
- Are large, major roots severed? Large diameter roots (greater than 1”) do not regenerate roots as well as smaller roots.
- All trees that have had root disturbance will need adequate moisture to encourage regrowth of roots. During periods of dry weather, apply 2-3 gallons of water per inch trunk diameter as needed. Do not overwater, saturated soils can inhibit root growth.
- If soil below the rootball was blown away leaving air gaps, replace with native soil. Avoid piling soil on top of roots. Mulch lightly with a natural product such as pine straw or wood chips if fibrous roots are exposed.
- Remove any broken, twisted, or split branches from the tree canopy to prevent further damage to the tree or property below. Remove as little woody tissue as possible; the tree will need stored energy in living wood to help it recover. Prune back to the trunk, branch, or node depending on what will leave as much tissue as possible but reduce risk of injury. Make smooth, clean, angled cuts that preserve the branch collar or next viable bud. Sprouts generated after pruning should be left to help support the tree.
- Do not top trees.
If broken trees are not threatening injury or further property damage if left alone, consider leaving them in place. Snapped tree trunks and fallen trees can provide important habitat for wildlife and birds. Cavity nesting birds like some species of woodpeckers, nuthatches, and chickadees make their homes in dead and decaying wood. Snags are also used as perches by predatory birds like hawks and owls. Squirrels, possums, raccoons, salamanders, and a variety of insects find homes or food in and around decaying wood like snags or fallen trees.
