Non-blooming daffodils - now what?
Over the past 2-3 years fewer and fewer of my daffodils have bloomed. This year probably about 70% of them have healthy foliage, but no buds. They get plenty of sun in the winter and early spring, before the trees leaf out; thereafter they are in partial shade. I do let the foliage die back naturally every year rather then cutting or tying it up. I planted them with Bulb-Tone, but haven't really done much to fertilize them since. Is that the problem? If I fertilize them properly this season, will they return to blooming next year, or are they a lost cause, to be yanked out? And when should I fertilize? I'm willing to give them one more season, but if they don't bloom next spring they're toast!
