Expecting near freezing temps next 3 nights

Zone 4 | drptech1 added on April 8, 2012 | Answered

We are expecting near or freezing temps the next 3 nights (28 degrees to 34 degrees). I have covered most of my perennials that are a least a month ahead of schedule because of our mild winter and early spring temps. How long can I leave them covered, or do I need to uncover them daily and then re-cover? I have lots of plants and not a lot of time. I guess my question would be, can I safely leave them covered with paper sheets and buckets for 3 days?

No, you cannot leave them covered. They must be uncovered each day, or they may suffer for the lack of light.
