daffodils smaller this year
I have some sort of generic yellow trumpet daffodils (one of those bushel basket deals) that I planted about 4 years ago. They are looking significantly smaller this year, as they begin to bloom. I know it's common for blooms to be slightly smaller the second year in the garden, because our gardens may not have the optimal conditions of the Dutch growers, who were responsible for that first year bloom.
But these are ALOT smaller. A few things I've considered: 1) Crowding. But I don't think that's it, mostly because the clumps blooming so far of this type actually seem very skimpy as far as foliage, too. 2) Rotting bulbs. We had a very wet 2009 here. Could alot of large bulbs have rotted, and I'm looking at blooms of immature bulbs? (My Dutch Masters seem to be pretty much the same size as last year, by the way.) 3) Moving. I did move these bulbs last summer, but I waited till the foliage was pretty well yellowed. (This is also the other reason I don't think they're that crowded.)
Ideas? Thanks in advance!
