How To Save Your Trees During An Ice Storm

With the threat of an upcoming ice storm in the Sioux Falls region, here are some things to remember when dealing with ice on your trees. There is little anyone can do during the storm (other than pray), but there are things that can be done before, some tips to remember during, and keys to repairing damage after the storm.

BEFORE THE STORM

The best medicine for having trees survive an ice storm is prevention. Ice storms will expose trees with weak branch attachments, co-dominant trunks, and other “defects” that a qualified arborist would find and work to correct or remove during a pruning program or  structural tree risk assessment. A tree with a strong central leader or strong branch attachments and for for its species will hold up far better in a ice storm or other severe weather better than a tree. This may not help for the imminent storm, but planing for the future and your young trees will save a lot in the future for the next storm.

DURING THE STORM

During the ice storm event and until the ice melts, there is nothing that you should be doing. Do not try and knock off the ice as this will likely cause the limb to break from the shock. Trees are designed to stretch and bend. Any quick shocks or instant bends will cause them to break far easier than if they bend slowly. Do not spray more water on the trees to try and melt the ice and or snow weighing them down. Also, do not try and prop up and bending or satin limbs during the storm. Just touching them with the weight of the ice could cause them to break. Your best options is to sit on your hands and wait for the storm to be done and the ice to melt off the trees before you start cleaning up any damage that happened.

AFTER THE STORM

With any weather events there will eventually be tree damage depending on the severity. I would first suggest that any restoration pruning wait until after the ice has melted or the situation is safe enough to be out working on the trees. Additionally, any ice that is still on the trees while working on them can cause further damage from the weight of the ice. Avoid leaving broken limbs in your trees and make sure the broken or torn parts of the tree are pruned back to branch union or ‘crotch’. That will promote sealing of the wound by the tree and reduce any future threat of decay or excessive sprouting. If you are hiring an arborists they should be familiar with storm restoration pruning and retrenchment pruning. These are industry standard definitions that will be the best options for the tree to repair and  recover from the damage. Finally, all trees should be visually inspected for any structural cracks or damage that could result in future tree failure that may not be obvious to the untrained eye (especially large mature trees near homes or other high rtarget areas).

Warning! 

It is sad that I have to mention this, but if the storms are bad enough and there is a lot of cleanup needed. Beware of people posing as arborists to do the work for a quick buck. Hire only reputable businesses that have the Sioux Falls license, have proof of insurance to provide before they start work on your property, and wear helmets and other safety gear while working. Also, avoid paying up front for any work to be done and be wary of people knocking on your door offering their services.
