I need help knowing how warm to keep my greenhouse over the winter if I want to keep things like hibiscus, coleus, caladiums, double impatiens, fuscia, and begonias. Every spring I spend a fortune on these plants and I'd rather just keep them alive than throw them out or keep the rhizomes. But this is our first full winter having the greenhouse, and so I wondered about:
What temperature?
How much do I water?
How do I care for plants that usually aren't kept over winter?
Are there any plants that just don't do well in your experience in a greenhouse?
Can you keep tropicals and others together in the same greenhouse with the same temperature?
I would appreciate answers to any of these questions. Thank you so much!
