It’s not yet officially winter, but the vegetative world is napping. Do you miss the aphids? Do you miss them enough to get a greenhouse for them?
Prices have come down significantly in recent years, some of the most modestly-priced from Harbor Freight. A 6-by-8-foot greenhouse is on sale at times for $299 through this vendor. Check for shipping charges on any greenhouse you want to buy, because those charges can be substantial.
You can also build your own of polycarbonate panels or recycled materials, but there are a number of other things to consider too.
