To ensure your shrubs make it through the winter damage-free, there are several things you'll have to do and in the process you’ll be preventing many landscape-associated headaches come spring time. There are three main threats to shrubs in the winter months and those are wind damage, snow-weight damage, and salt damage. I'll start with wind damage. Please check back tomorrow for information on snow-weight damage and salt damage.
What you need to know about wind damage:
The cold winter wind is capable of excessively drying out the shrubs that maintain their foliage in the winter. This is called desiccation. During desiccation, the drying process is caused by transpiration of the water within the shrub’s foliage.
Another easy remedy is to wrap your shrubs in burlap, or creating a burlap screen for your shrubs to shelter them from the wind. Damaging winds will be blocked by the burlap therefore protecting your tress from additional water loss and drying. Burlap application is another service that your local tree care company should be able to offer you if you don't want to tackle this yourself.
