Katsura leaves turn brown
What makes my Katsura leaves turn brown? Every summer after the leaves have come out, it isn't long before all the leaves are turning brown. I first thought it was a fungus so I sprayed it with a spray for brown spot and tree disease that did not help. Then I sprayed it an insecticide in case it was caused by insects, that did not help. I really need help or I'm afraid I will lose it.
Make sure your tree is planted properly, not to deep.
A little bit of shade protection is the perfect spot to plant.
Mulching is helpful.
