Q.Does My Lemon Tree Have A Disease?
My lemon tree’s leaves have always had a problem turning yellow, and I always thought it was a magnesium deficiency. Today, however, I found some brown spots on a branch and think that my plant has a fungus or disease. Problem is I am having trouble identifying it. I am hoping you guys can help. Much thanks in advance.

There could be several problems going on such as insects, overwatering, or fungal issues. Spraying the plant with Neem oil should get rid of any pests and it could help with a fungal infection, too.
