River birch tree

Question

My river birch has many suckers all around the base. I have cut them off but they grow right back. Do I just leave them or keep cutting them off? And the leaves are a pale green to yellow. Is that normal? Thank you.

Answer 1

Keep removing them! I have to get a few off mine too!
Iron deficiency may occur, especially in alkaline soils. This is evident by yellowing of the leaves. This problem is called Chlorosis and can be treated by introducing iron tablets into the soil.
