I'm living in an apartment right now and would like to build a small enclosure to try to overwinter some plants. The picture below is the area I would like to try it, it's 6-7 feet tall at the top. I'm thinking simple, black tarp along the back and ground for some added warmth (I'm in Oakland, CA so it will rarely, if ever frost here). The wall faces south, and with some 2x4's, a couple shelves, and some plastic sheeting I should be in business.
Any tips on materials, design, layout, best way to ensure some ventilation but maintain warmth, access ideas, etc.? Since it an apartment building I would like to be as delicate as possible, as in not putting holes in the building with screws or nails if possible.
Number of plants isn't all that important as long as I can keep a handful (5-6 would be great, the more the merrier).
I just moved to Oakland, CA and have some plants in a raised bed I'd like to try to keep alive over winter. My place is an apartment and I don't have room for them indoors.
Can I transplant to fabric pots and put them in a place where it gets some sun (thinking the roof)? Oakland is Zone 10a 30-35 degrees. i can cover them at night if needed. Overnight lows in winter are usually in the low 40s with occasional 30s but it doesn't really frost here.
Anyone else keep their plants alive outside with these temps?
