Ms. Fox: or perhaps if You can't or don't want to move Yours You could put something over it to shelter and protect it when it rains? a translucent tarp held up with some kind of sticks or a trellis-like rig or something, maybe? something to serve as an instant and temporary greenhouse.

i'm sure if such a thing is commonly done, Ms. ajtgirl will be able to tell You about it...
