The leaves have been drying, but haven't quite dropped yet. I have been spraying them to help out and I did soak in some ashes with the initial planting last Sunday.
I will find some high K fertilizer. Don't know how quickly ashes are usable by the tree.
If the leaves are as good as gone perhaps just let it go to sleep, as Kiril suggests. The K won't do any good once the leaves stop circulating nutrients, correct?
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage,,, I wonder what does...
