I have a Meyer lemon that I keep outside in the summer. The forecast is saying it will get below 50 degrees Friday night. I can't remember where but I think I read that Meyer lemons can't take weather below that temp. I checked the USDA zones Meyers like and the zones can get a lot colder than that. What do you all think? Should I leave it outside and see if it's ok? I normally keep it out a few more weeks into September but I'm worried about the sudden chill. I have a Bearss lime too but I think they are a bit hardier or am I wrong about that?
I'll probably just play it safe and bring them both in but I'd like to let them enjoy the outdoors as long as they can.
I think I remember reading somewhere that all citrus plants stop growing when the temperature drops below 50 degrees which may be where you came up with that figure. But I think all citrus will be OK as long as it stays above freezing, just that the plant will not grow until the temperature is above 50.
My Improved Meyers Lemon can handle low 20's before it loses leaves. It starts to get branch damage in the upper teens. If it is in a pot, then just bring it in if it gets below freezing or push it up against the house with the pot covered in a blanket. If you go below 26F in a pot, you are asking for trouble.
