Some of my Daffs aren't blooming!
I planted a good number of different varieties of Daffodils in clumps of six throughout my front garden beds. The oldest of these are Dutch Master, planted about seven years ago. I've never divided them and this is the first year they have no flower stems . . . lots of leaves, but no buds. Here in Zone 7 they should be blooming now.
I've fertilized them with Espoma's Bulbtone, but haven't done this every year. Their location is full sun and half-day sun, so I'm not sure what's wrong. They look healthy. What do you think is wrong? Do you think they need to be divided?
