Peach Tree's With Leaf Curl
I have a Peach tree and Nectarine tree in our garden both of which are potted in large containers. I have a problem with leaf curl though which is affecting both trees. I am sure there is a treatment of some sort which can be applied to the soil in the container rather than by spray application to the tree itself but cannot locate anything. Does anyone have any ideas or suggestions of what would be best to use for this problem?
I have already treated both trees with winter wash and copper sulphate mixture but this has had no real effect so far.
Many thanks, Peter
