We are in a fairly mild climate, but do get cold/freezing weather in winter. I bring in my asparagus ferns (though I do leave some in the beds and they do fine), my bouganvilla, cactus, wandering jew, and geraniums. I have a south facing dining room window and also one in the garage with a shelf and my storeroom has a small south window and we put an old door with glass panes on also, so it gets lots of light.
I hope to get some lettuce in the ground this week if it dries out at all. We have had our annual rainfall a couple of times over this month. Very strange, but nice. If I get the lettuce up, I can cover it with bubble wrap and harvest well into the winter months. Our first freeze used to be around halloween, but the last couple of years has been around Christmas.
