My neighbor just sent me the LCRA weatherman's prediction for next week..and it looks like we'll be in the 20's for a few nights. His suggestion was to use the next few good days to prepare for it. I have two heaters in the gh in the photo, but I think I'm going to run some row cloth along the bottom of the front of it. The north wind blows straight across the yard and I have a lot of pots on the ground in there. Wish I had bought some bubble wrap to string along there. We get so few freezing nights, but I guess it only takes one to ruin my spring!
