Frost on Plants.

 I think I was spared last night. If you weren't, you should know by the end of the day how much damage was done. Minor damage in some plants, could take a few days before you can visually see the damage, some may be immediate. Frosted perennials are really not much of a problem. If some of the tissue has died back, using a scissors, cut it back to healthy tissue. Like some other garden equations, it's a temperature x duration factor as to the amount of damage you may have. perennials are tough and will re-grow. Tomatoes, peppers or other warm weather crops, not so lucky. Warm weather plants will not survive frosts. According to the zone 4 climate, which is here in southern MN, we can have frost into mid May. That's the problem with an unusual season, folks get over confident.

You can cover plants like shown above. You can also use pails or buckets. You want to make sure you bucket is large enough that it is not touching the plant. Frost only happens on calm nights, not windy, so you shouldn't have to worry about pails blowing into the neighbors yard. Lightweight fabrics are okay, and some 'frost blankets' are designed just for this purpose. Rugs and heavy stuff should be avoided as they will likely crush small plants. Frost in predicted here for tonight again. Brrr.
