Thanks Mike,
As if you couldn't tell it is raining here today, and I am stuck inside (explains all the posting).
I only have to cover my plants for a few days at a time, the temp. just drops down below freezing normally for short periods. This time the plants will be covered from Tuesday afternoon through Friday morning. Being the plants have individual covers not an entire area covered I think even for a more extended period the moisture level would be fine.
I do have a few daylilies and "Regular Lilies" under plastic that have been there since early in the year when I bought them and those I do have to water on a regular basis. I do get concerned about the plants under pots that don't let the light penetrate, don't know what effect that might have on them.
