Diseases in Roses
By:Darcey
I have 3 x standard roses and 5 x other variety (unknown), they have all been very stunned in growth this season with 2 looking almost dead. There are red dots on leaves of all the roses - I think it's a magnesium deficiency Any ideas on how I can get rid of the red dots and why 2 out of 8 are not growing?
