Denver Hail Storm: Swingle CEO Addresses Property Owner Concerns

On the evening of July 13, 2011, hail stones that reached the size of baseballs stranded about 1,000 travellers at DIA and wreaked havoc on Denver and Boulder, Colorado, metro area trees and plants.

“Hail storm damage can continue long after the skies have calmed,” said Tom Tolkacz, CEO of Swingle. “Property owners should arm themselves with good information, then act quickly and properly.”

Here are some things we'd like our customers to know about Colorado hail storms and what to do after they hit.

Can hail damage kill my trees/shrubs?
NO.

What will hail damage do to my trees/shrubs?
Hail damage alone typically does not affect the long-term health of trees or shrubs. It can compromise the plant’s ability to produce energy, consequently stressing the plant. Hail damage strips leaves that make sugar (energy) for the tree. Producing new leaves uses stored energy which is added stress on the tree, leaving them more vulnerable to pests and poor environmental conditions. Hail damages twigs and branches causing hundreds of small wounds on the tree. Trees such as honeylocust and poplars may also develop small cankers where the branches were damaged. These wounds disrupt water flow and opens wounds for disease. Trees and shrubs will repair themselves, but this takes energy.

Will my trees/shrubs get new leaves?
When plants are severely defoliated, a healthy tree will produce new leaves in 2-3 weeks. The tree will likely look “sparse” for the remainder of the year. Trees that are in poor condition may produce fewer leaves and take longer to do so.

Should I continue insect control treatments on damaged trees/shrubs?
It is very important to continue to protect your trees and shrubs.  The remaining leaves and any new leaves that the tree is producing need to be protected because they are vital to produce energy for the tree and helping it recover.

What can be done to minimize long-term effects of my plants from hail damage?
The most important way to mitigate hail damage is to reduce the stress and help the tree recover by proper watering and fertilization to promote root growth.
