I have read thru the info page on Rodo's but I cannot find anything that seems to match my plants conditions. I have 3 plants only one is sick the other two are seperated from it by two evergreen bushes. The sick plant has small black spots on the leaves. The leaves are turning yellow, then brown patches, then brown curl up and fall off. HELP PLEASE.... IM KINDA NEW AT THIS.
there is a possibility that the two evergreens are robbing your rhodie of water and nutrients. in hot weather especially, they need deep water. also, did you plant the crown to deep?
