Dying Grapefruit Tree
My poor grapefruit tree is dying. I've had it for 10 years and it has always been strong. Last year I lost a Lemon tree; this year the Grapefruit is doing the same thing. I don't know how to help this poor tree. Please help me.
The image in the link is what the plant looks like right now.
I'm in Southern California if that matters.
