Unfortunately, my DH is a little OCD about things being organized. He is one who strongly believes that cars should be stored in a garage, yada, yada, yada.....He did provide a metal shed for potting/storing plant supplies, etc., completely set up with shelving and lighting, but unfortunately, it does not work for overwintering tenders. It will freeze in there and there is no ventilation. He's putting off getting me a greenhouse.
But he knows that he will have to sooner or later.
I prefer to keep my dormant/semi-dormant tender plants in the garage, as I know that they are protected from freezing. I just need to get things organized--shelving and additional lighting. At present, I only have one under the counter fixture in there and one window, although it is not a sunny one. That was sufficient enough to get by last year, but not now. I was recently gifted some large aloe veras, a tall pencil cactus, and some baby kalanchoes,etc. So I have to make room for those as well.
I'm working on removing unnecessary clutter in the area, so that I can store my plants, which keep increasing in number each year. Houseplants had to be rushed in the garage, because we suddenly had 2 nights of frost last week. They need to be debugged before I bring them in. A work in progress.
