This is probably not too helpful for your conditions, but I grow them in pots here in southern California and they're like weeds. I give them almost no care and they seem to survive in the climate conditions we get here just fine. If the winter is very dry, I'll give them supplemental water since they're in pots, but that's about it. I used to fertilize them, but they made so many offsets that I had to re-pot them every year. Even so, every couple of years when I dump the pots out, about 3 inches down, it becomes a solid layer of flat disks stacked on each other covering the entire cross section of the pot. This doesn't seem to bother them much because they all sprout the next fall and bloom as well. But then it really needs additional watering since there are so many plants growing in the one pot. I grow them in 1 gallon pots. Also, I found out by accident that the bulbs are really tough during dormancy. I had set aside a bunch one year to send to the BX and forgot about them for more than a year. Even so, although they had sent about a 1/2 cm of leaf out the top the previous fall when it got cooler, they stayed that way until the following fall when I put some in some soil and then watered them and they grew just like normal. Maybe that's how they were converted to summer growth. I would think that during dormancy you'd need to keep them inside or someplace else very warm and dry. Then when you wanted them to grow you could set them outside in the Pacific NW where it would think it was a South. Calif. winter since it's so cool there in the summer. But I think you'd need to bring them into someplace where it was even warmer (80s or 90s F.) in the fall to induce and then maintain dormancy during the winter. --Lee Poulsen Pasadena area, California, USDA Zone 9-10
