The warm weather we had earlier this week was a welcome break from the winter temperatures, but it may have caused problems for some plants.
During the winter, a couple of days in a row with abnormally warm temperatures, will cause dormant plants to lose their tolerance to cold.
If a warm spell is followed by a quick drop in temperatures down to the single digit range, damage is likely to occur in some plants. The temperature in many locations in our area did drop that low — well over a 40 degree difference.
Plants will get back their cold tolerance if the winter temperatures stay cold. We’ll have to wait until spring to find out if any plants actually were hurt.
