Most definitely. I've had 2 yellow/pink bicolors that dwindled over the years, under the same conditions many were multiplying like mad. They were Billy Graham and Fidelity. BG is still hanging in there, there are 4 or 5 blooms after having it 10 years. I'll dig them this year and move them to an amended spot with bone meal. I rarely go to any trouble with Daffs as far as fertilizing is concerned, aside from an occasional light broadcast of bone meal over the whole bed. But if I'm giving one tlc to try and bring it back, I'll go to some extra effort for a really pretty one. Fidelity died out completely. It was in a spot where there was too much shade and competition from tree roots, where Ara had also dwindled. A tree and some big limbs were removed and there's plenty of sun now.
