In the midst of cold winter weather, keeping frost-sensitive plants alive can be a challenge. Although this year has been a warn winter so far, we expect some cold weather over the next couple of months so here are some helpful tips to guide you through those frosty nights.
* Plants should be thoroughly watered, especially those in containers, several days in advance of the frost. However, do not saturate the plants while the temperatures are extremely low, as this will result in frost heave and ultimately injure the plants. Light watering in the evening hours, before temperatures drop, will help raise humidity levels and should help reduce frost damage.
* Do not fertilize with quick-release nitrogen in the winter months. Actively growing plants are more susceptible to frost damage.
* When possible, cover tender plants. Frost blankets can be purchased and, depending on thickness, can add 3 to 7 degrees of warmth for plants. You can also create tents over plants with space between the protection barrier and the plants.
* Passive solar protection may help. Place jugs of warn water or dark plastic objects near plants to absorb warmth in the day and then let off that heat at night.
* Mulch will protect some frost-sensitive plants. When mulching, try to keep it at a depth of 2 to 3 inches. Call Allison Lawn & Landscape Services to add or refresh your mulch.
* If plants are damaged by the frost, we will wait to prune them until spring. They need to remain dormant, rather than expend energy to heal pruning wounds.
