Fred, Based on my own experience only, *Nothoscordum dialystemon *blooms best with rather heavy fertilization during active growth, especially during emergence. I consider it one of the 'heavy feeders', and use a high phosphorus, dry, organic fertilizer. I've read that it never wants to completely dry out during dormancy. I water the pots that contain the bulbs plus other plants (*Gypsophila aretioides*) during the summer, and these bloom best. However, I try to keep these pots on the less watered side. The soil in the pots containing only summer dormant bulbs is kept dry during dormancy, but never completely devoid of moisture. These bloom well (with the fertilization), but not quite as well as the ones that get some summer watering. All that said, the bulbs do seem to respond well to rather heavy watering during the period from emergence to bloom. As an aside, although this doesn't pertain to your bulbs which have been in the pots for years - in my experience, *Nothoscordum dialystemon *bulbs take a season or more to bloom after being divided. Occasionally they will not even emerge for a whole season after division, but will come out of dormancy the following season if left alone. This is one of my favorite small bulbs, with its bright, sunny yellow blooms during a drab time of year that fill the whole hoophouse with their fragrance on the very occasional sunny days that heat up the hoophouse. This is all based on my growing conditions in my minimally heated (at times, temperatures drop below 32℉) hoophouse, in western Washington zn. 7 (relative-Mediterranean), and my mixed success in growing bulbs in pots. The *Cyclamen coum, *various* Galanthus, Eranthis, **Scoliopus bigelovii* *and Crocus tomm*. were in glorious bloom two weeks ago before being covered by 25" of snow, which is melting very s l o w l y.
