This spring has definitely been different, so it should be no surprise that we would have a late Spring frost. Some hardy plants can handle light frosts, others can handle the dips below freezing. Few, however, can remain intact when the temps drop much below 32 degrees.
I recommend covering young plants as best you can, and if you have potted plants, bring them inside, or even under a covered patio or garage.
Here are some materials you could use to cover:
- Old sheets, drop cloths, tarps, burlap, or newspapers.
- Cardboard boxes, open them on one end, turn them upside down and place them over your flowers. Tape any cracks to keep out the cold air.
- Empty pots, buckets, milk jugs with the top cut off, or other containers made of wood, plastic or clay to cover your plants (just be sure they’re tall enough to fit over plants without crushing them.
- Pre-made row covers (from a gardening store)
- Place covers over your plants before the temperatures hit freezing. If you’re using plastic covers, wait until twilight to avoid the sun cooking your plants through the plastic.
- If your cover is lightweight enough to blow away in the wind, weigh it down with rocks or bricks.
- Remove cardboard or fabric covers as soon as the weather warms up.
- Remove plastic covers as soon as the sun rises.
