What's wrong with my grapefruit tree?
Our little grapefruit tree was planted seven years ago. The first few years, we didn't let any fruit grow, figuring we should let the tree strengthen a bit. For four years now, the tree blooms every year, then everything just dries up -- no fruits at all. Not even one!
We've watered regularly; we've put in some nutrients (those "stakes" that are knocked into the ground) ... nothing.
It's beginning to dry already this year as well. What can I do to save them? This year? For the future?
