Lime (only) leaf drop
Having discovered gritty mix through this forum, I was thrilled to have my citrus stop dropping leaves and survive. Through summer and fall they all did great (except for a key lime, which somehow ended up with root rot. I repotted it in new gravel mix and it seemed "ok").
Now, some of the citrus have partial leaf drop, ESPECIALLY the Kaffir lime. It spread from the trunk outward, and now has stopped. The dropped leaves are all green and healthy-looking. I'm suspecting the light level change had something to do with it, but would appreciate your (more knowledgeable) opinions. Do you normally acclimate citrus slowly to moving indoors?
