I have planted a rose in a heavy clay soil. I mixed in some perlite to hopefully help with the drainage and put some gypsum in the base of the hole. other than that I have not done much. The rose is alive but the new leaves came out deformed and now are yellow and wilting. the leaves at the base look green and happy. Is this a root rot situation? nutrients? maybe a pest? Was thinking about digging it up and actually mixing it in with decent soil but wanted to see what you thought.
