Hi, I have a sweetheart Lychee tree that has put out flower spikes for the first time since I've had it. Its outside and I live in Alameda, Ca. I think we will have a cold spell in the next few weeks/days down to 38 degrees. I'm not sure if I should leave the potted Lychee outside? At what temperature shouldI bring it inside. Its also been rainy, should I protect the tree in any way (ie wrap tarp around the base? ) or just leave it? SHould I try to prevent too much rain from saturating the roots or will it be fine through our normal rainy season. I heard that Lychee are river side trees so I'm thinking the water won't hurt it as long as it's got drainage? Any advice really appreciated!
