This dracaena and trailing pelargonium are overwintering, dry, dark, in the garage. It is attached so doesn't freeze.
The brugmansia overwintered in this spot last year, same garage. The cannas were dug up this tijme because several died or did very poorly with overwintering outside last year. Some pelargonia and zantedeschia are overwintering in this situation as well. The more tender zantedeschia dont survive winter here, but take to the dry/dark/cool method very well.
This is the spare bedroom that, until a month ago, had a carpeted floor. You cant see the spot here, but there is a 1X3 foot plywood patch on one side. The rest is a nice hardwood oak floor, full thickness tongue and groove oak. I need to get saucers under a couple of pots (as soon as I finish this posting). The cacti (Epiphyllum and a coujple of opuntia) should be OK here since they have wintered for several years in the room. The citrus are a bit anemic but as long as they survive, that's OK. There is also a small brugmansia - we'll see how it does, a cavendish banana - last year it died down to the container, and I would like to keep more of it alive if possible. An aloe, and two gingers are also present. the gingers may be OK outside or in the garage, but i wanted to see if I could maintain them green for a head start next year.
