I have some of the pink surprise lilies, and one group has refused to bloom for over a decade, despite growing healthy green leaves that I always leave in place until they dry out. The other groups bloom. I think I have figured out why. I live in what is mapped as Zone 7a (minimum temp. 0°) but colder winters, single beow zero digits, occasionally make us 6b. I planted this non-blooming group on the south-facing side of my house and I think it's in a microclimate there that is considerably warmer, plus these bulbs were probably planted too deep to ever reach a minimum temperature they require to bloom. I just dug them up (I know, wrong time of year) and planned to give the bulbs a brief hardening off/drying period before replanting in a spot out of the microclimate. But also debating whether to wait until fall to replant. Anyone have more suggestions on planting time?
