Perhaps this is the worst that winter will deal us this winter. Be prepared! There is no guarantee of that. Low temperatures for the next two nights are forecast to be in the single digits. One thing to note: Plants do not feel “wind-chill”, that is reserved for us mammals…without fur. Do not let “wind-chill” forecasts overly alarm you with regard to your plants…but the wind does dry them out so don’t forget to water, when the weather warms early next week.
Typically the plant’s roots are protected by the earth itself. This is very tolerable for most plants. There is one area of exception: Containerized plants. Since I covered this last week, I will not re-iterate.
Perennials deal with winter by letting the cold kill off the parts of the plant above the ground. The roots survive the winter. Trees adapt well. It's normal for some water to freeze inside tree trunks during the winter. Fortunately, all trees are completely dormant.
Conifers, such as arborvitae, juniper, yew, pine and spruce, don't lose their needles because they have so much natural antifreeze in them, therefore naturally resistant to freeze. Even though the needles don't drop off, they can lose moisture to the winter winds. Occasionally we experience browning on evergreens caused by desiccation (drying out of foliage).
Have a safe and warm holiday!
