. It is sad, and I'm not sure why. Please help me make my grapefruit tree not so sad and nearly dead. Details inside.
I gave this 5 gallon tree to my parents a year ago or so, and it lived outside in Santa Barbara, CA. It survived a move to New Mexico, but it got cold here, so we brought the tree inside, and now it is sad and nearly dead.
It gets water, and it lives near a window. The room is warm, and the tree even blossomed for a while. Then the blossoms died, and the few leaves started falling off, too.
I know the room isn't a death trap for plants, because this orange tree
is right next to the grapefruit tree.
What can I do for my grapefruit tree? One thought: the soil has washed away from the base of the trunk, exposing the top of the roots a bit, but it's been this way for a while. Could more soil help at this point?
