Help! My dwarf Lemon Tree is sick
Ive had a dwarf Lemon Tree for 5 years, I havent had a great deal of fruit from it, but ive noticed lately, the branches are dying off and then turning white Also white specks appearing on the leaves. See picture.
Ive cut the dead branches all off now, down to a green part of the branch, but im worried it will take over the plant as i dont know what it is :(
I have bought a larger pot to re-pot it in fresh helathy soil, but before i do that, is there anything else i can do?
(im in Australia)
