have I killed my Dahlias?
Hey guys Hoping to get some advice here on my dahlias. So I purchased some online last Sept and they arrived Friday. All neatly packaged etc but I was expecting tubers and these were young plants. Never mind I thought and followed the instructions of what to do with them to bring them on. Having had huge success with the tubers year in year out I thought this would be no different but after I potted them up and watered them I noticed a couple had started to flop. I put this down to shock and most plants recover after a few more days. But these have just got worse. The smallest ones foliage turned a very ashen shade with dark patches in the middle of the leaves and the others quickly followed. Today they are at their worse, most of the leaves are limp and dead. I've tipped them up and the root systems look healthy but the leaves are horrendous. I'm really hoping they will recover. What should I do?
