Hello, Dan from Niagara. I have looked throughout this site for many months and this is my first post. I have 3 citrus trees; a meyer lemon, kumquat and a mystery lemon. I have attached some photos of the mystery lemon, I cant seem to find anything on this tree. The leaves are different then the meyer, waxier when young and much rougher when older. The older leaves are also dark and light green as seen in the pictures as compared to my healthy meyer lemon. The Italian man I bought them from didn't know what it was either. My second question is, on my meyer lemon tree I've been noticing some brownish yellow foilage on the lower part of the plant. I have some comparison pictures with healthy leaves. Can someone identify if this is a nutrient deficiency, natural or something else. I use a general purpose fertilizer 20-20-20( I think), water deeply once every few days or until soil looks dry. Thanks, Dan
