When powerful winds come through with a storm like Hurricane Isaac, they can do more than just cause a bad hair day. They can delay flights, cause power outages and result in varying kinds of damage to trees, ranging from foliage loss to broken limbs.
Trees differ in their ability to withstand strong winds. The density and strength of the wood, the branch structure and expanse of the roots are factors influencing wind tolerance.
Ways to minimize storm damage to your trees include pruning to reduce deadwood and canopy density, along with installation of flexible steel support cables to strengthen weak or problematic branch unions. These are not a guarantee but are proven to minimize wind damage.
To revitalize wind-damaged trees, experts recommend removing dead and broken branches; cutting damaged or exposed roots to enhance regrowth, keeping roots moist through mulching and watering, and fertilizing with a slow-release nitrogen source.
Corrective actions can often alleviate damage and revitalize trees.
