We are having 2 nights of unexpected freezing temps. I found a bunch of large Monarch Cats on milkweed. Some had moved to the large salvia right next to the milkweed and moved down lower to the ground on the plant. I covered the 2 plants and cats. I dont think the freeze will last more than a few hrs each night. The day temps will bounce back up. Will they be ok this way?
