This years Rhubarb has gone very thin and it was well manured with horse/household compost as it is every year. It was also split about 3 years ago. What can be done to improve it?

The main problem with rhubarb is shading from trees and the taking of moisture from the soil by trees. This gets worse are the trees expand.
If this is not the problem, it may have been caused by honey fungus or wilt disease. If there is no improvement, you will have to start with clean stock.Â
