Hi all, I have a Forsythia at the top end of my garden that I cut back to the ground last year due to the fact that it was pretty neglected.
This year the growth has been ok but as I've been up there doing some work I've noticed that the trunk at the base is all black with a few white patches in it.
This seems to have made it weak with the branches basically falling off in my hand and the leaves are all wilted.
Does anyone have any idea what could cause this?
I know that it's been the wettest Summer in 100 Years and the soil in my garden is Very heavy Clay, I have no idea if this would contribute to it.
