It's finally looking like time to start hardening off plants. I'll start moving things outside for short periods during the day. I'd rather expose them to morning sun, but our mornings are still pretty cool.
I have a few Dragon Wing begonias, and a few tuberous ones that I started in the house. What's the coolest temperature they should be exposed to? I'm thinking about 55. Or are a few hours of 50-ish OK?
