I planted dutch masters in the fall of 2001, and had flowers every spring. Then in the summer of 2005 (or 2004?) I redid that bed, and replanted the bulbs. Perhaps I divided them into smaller ones, but all of them? In any case, they come up every spring, and I definitely have more, but last year and it looks like this year again, no flowers. Is it just a matter of time until the bulbs get large enough again? Other bulbs in the bed have bloomed - tulips (turkestanica, chrysantha) and lilies.
