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: http://planetoblivion.de/img/Katherine_Small.JPG/ Actually, I think they're more beautiful if not stuffed as close... -- Martin ---------------------------------------------- Southern Germany Likely zone 7a Am 19.03.2016 um 21:53 schrieb Dennis Kramb: > I've tried different reticulata varieties from big box stores, but they > never persist in my garden.
