Does anyone else grow and overwinter their tender bulbs (I have glads, dahlias, eucomis, acidanthera, oxalis, calla, canna, Peruvian daffodils, Amorphophallus, Zephranthes, and a few others) right in the soil in pots?

I got sick of digging and planting, digging and storing, a few years back. So, I potted them all, and now I just cut off the tops after frost, let them pots dry out a few weeks in a dry place (garage or greenhouse), then store in my basement or barely-heated attached garage.

They store MUCH better this way than when dug. I used to have problems in particular with glads and dahlias rotting. Not now.

Of course, it does take a bit of room. I've got about 30 pots of various bulbs, most are in 18" square containers, and a few are larger tubs about 22". I just tuck the pots under of behind things, and I also stack them 2 to 3 deep if possible.

They go back outside in mid to late April after the danger of hard freezes is over.
