Why lemons won't turn yellow?
We have a Meyer's lemon tree. Recently, we've been getting large lemons that won't turn yellow. These lemons have been growing on the tree for 3-4 months. One lemon, in particular, is approx 9" in diameter (size of a small grapefruit) and is very green. Other lemons on the tree are approx 6" in diameter but also very green. What causes lemons to grow to such large sizes but not turn yellow? Thank you for your help!
