Dormant Plants Still Need Water
Winter-hardy plants in our area generally go dormant for the winter months. Even though the plants aren’t growing, they require water. Regular, but not excessive, watering keeps them alive for their spring renewal. Watering your lawn remains important for the same reason.
It’s particularly crucial to water trees and shrubs during winter drought conditions to keep them healthy. Long-term drought conditions compromise a plant and can cause it to die. It’s best to water when soil temperatures are above 40 degrees Fahrenheit to avoid freezing the plants’ roots which can damage them.
Potted Plants Need More Protection
Plants in pots and containers are more prone to winter damage. The relatively small amount of soil around the roots offers less insulation. Keeping potted plants in protected areas during the winter, such as in a greenhouse, enclosed porch or next to a windbreak helps to protect them from temperature extremes. Covering vulnerable plants can also help.
Winter Wind Ravages Plants
In addition to the problems of extreme temperatures and winter droughts, Old Man Winter blows strong winds that whip through a landscape. Wind causes cold temperatures to have a more extreme effect in what’s known as the ‘wind chill factor’ and the force of the gusts can break branches and even destroy some plants.
Wind also increases the risk of dehydration. Houses and fences provide a wind break for some plants, but if you are worried about particular plants, you can cover them with burlap for added protection. Just make sure to remove it early in the spring so you don’t inhibit its growth or have problems with mold or mildew.
Saturated Ground Leads to Frozen Roots
When the ground becomes saturated and then freezes, the plant roots freeze, too. This can kill landscape plants. One of the best defenses against winter plant deaths is adequate draining. Mix mulch and sand into the soil so that it drains faster. For best results, water only when air and soil temperatures are above 40 degrees Fahrenheit with no snow cover.
