Q.my raspberry ice is inside and dropping leaves
My bougainvillea raspberry ice plant that I just transplanted and moved inside, because it is getting cold at night, is now dropping leaves. It has new ones growing. It’s standing in front of a window. I don’t know what to do. Is it normal for it to do that?

Whenever you move any plant from a place of higher light to a place of lower light, it will lose leaves, because there is not enough light to support them all. One way to avoid this is to acclimate the plant slowly: https://www.gardeningknowhow.com/houseplants/hpgen/acclimate-plants-indoors-winter.htm
If you live in zone 9, you may not have to move the bougainvillea inside, unless you're expecting a freeze. Here's more info on keeping b-- indoors: https://www.gardeningknowhow.com/ornamental/vines/bougainvillea/bougainvillea-in-containers.htm
