Help! Suffering lemon tree
This little lemon tree seemed to be thriving until last summer when everything started to go downhill. The leaves started to appear burnt around the edges. It dropped almost all of its leaves in winter. I live in AZ and this year it got hot MUCH earlier than usual in late February so the poor thing went through two bloom cycles about a month and a half apart. The tree produced a TON of flowers and a handful developed into tiny lemons, yet when they got to about the size of a large bead, they turned black and fell off. I’d noticed the same thing last year with the fruit but didn’t have any issues with the leaves so I thought it may be a fungus and sprayed an antifungal with no effect. This year I fertilized in winter, and it looked like it may have been making a comeback with that first bloom cycle. I plucked most of the blooms so it could focus on recovering instead of making fruit, same for the second bloom cycle, but I just keep seeing these charred edges around the leaves, even new growth. I haven’t really changed anything in my watering habits. Am I overwatering? Please help!
