I'm really not sure if I needed to bring everyone in again, but I'm firmly in the "better safe than sorry" camp. The temps are predicted down into the mid-40's here for at least the next week. I do know that all my plants did bloom and grow better last year after I brought them indoors than they did the years before when I didn't. Who knows if it was the cold protection, or new fertilizer, or the early spring warm-up or what?
Anyway, it's a jungle in here, and I do notice the air is really nice to breathe with all these plants in the house . ..
