Hi Dennis,

in my experience, the reticulatas are quite greedy. I'm usually a bit on 
the lazy side considering fertilization and had both plain reticulatas 
and the Katherine Hodgkin Hybrid weakening and disappearing over several 
years - until I planted some together with Hyacinthus Orientalis 
cultivars, which I fertilize with a bit of plain "Blaukorn", the cheap 
synthetic 12/12/17 + 2 stuff. Seems that did the trick for Katherine 
Hodgkin as well, they nearly exploded this year:

Actually, I think they're more beautiful if not stuffed as close...
