Protect Your Trees Against Winter Weather
As the weather gets colder, it is the time of year to be aware of major snow events and understand the impact that these storms can have on your trees. The buildup of snow, and precipitation that turns to ice, can be too heavy for some trees and can produce the dreaded “crack” resulting in critical damage.
Assess the Damage
You’ll want to wait to make sure the storm has passed and that it is safe to go outside. Once you’re able to get outside, you need to understand what has been damaged; Are there small branches that have been damaged? Are larger branches damaged? Before you go any further, it is important to make sure there are no tangled or downed power lines. It’s also important to understand if the tree is on your property or if it is the responsibility of your city; If that is the case, you’ll want to phone the city directly to advise them of the situation.
Don’t Shake the Branches
Once you’ve assessed the damage and can understand how much of your tree is intact there is a natural tendency to shake the branches so that you can remove the stress on the tree from the accumulated snow or ice. Don’t do this. We can’t stress this enough. Shaking the branches may actually cause them to snap and more seriously damage the tree.
Instead, gently push branches upwards from below with an extension pole; Watch for falling snow when you do this. If the branches are covered in ice, wait for it to melt naturally.
