I started the plants indoors from tubers in March and then took them out in spring. They made good progress and bloomed mid June but developed this disease (hopefully fungal not viral) early July and the buds stopped growing and blooming. Initially there was spotting on leaves from spider mited in addition to leaf yellowing in diffuse patches more like random discoloration. I sprayed with soap water and neem oil. I also fertilized I think alongside my other flowering plants. A few days later the leaves were wilting and looked like I was going to lose them. It was unclear if it was the spraying, fertilizing or the excessive rain. Anyhow, I moved them to shade and withheld water and fertilizer thereafter. One stem died but the rest regained turgidity but the blooming stopped as the new leaves became narrower, reddish and the buds refused to grow and bloom. I read up and it seemed like it might be an incurable fungal or viral disease and I was supposed to destroy the plants. I left them alone apart from removing spotted yellowing leaves. Now there is a lot of new growth both from the tuber and from older stem(at least one plant is producing buds that are growing and blooming). But the majority are still in a state of growth getting deformed and stunted. I could try another neem spray but previous experience is a deterrent. Any suggestions from veterans?
