if its in a pot.. its in media ... not soil.. but if the leaves are showing.. they could be FROST/FREEZE ... you will have to wait.. or protect them on any given night ... as i asked.. how warm is mother earth??? ... an inch or two down ??? .. some bulbs dont mind a refrigerator.. others.. the more tropical.. might not ... i doubt you are going to get a specific answer.. because this is all about your little micro climate .... ken

To be more specific and answer your question, after LAST frost I would put the pot outside. You are in zone 6 right? Keep in a sunny location, water well and after 1st frost follow previous advice. Here's what I include with bulbs I've given away or donated plant sales: Zantedeschia albomaculata: Calla Lily Form: Tender bulb. Exposure: Full Sun. Height: 24" (to 30" bloom). Spread: 18-24". Zone: 8-10. Flower Date: June-July. >Planting Reqs: Plant 4-8" deep and 18-24" apart when all danger of frost has passed (last week of May in ELong.). I plant those in back 4" deep and those in front 6-8" then cover all with 2" of compost/mulch. Fertilize using a 5-10-10 or 5-10-5 fertilizer. >Lifting Reqs: Lift the rhizomes after first frost, cut back stems, clean off excess soil, let dry out of the direct sun for a few days and then store in a dry location that remains between 50 and 60 degrees F. They can be divided before storage as long as the cut portions are allowed to dry. Doing so will prevent the open wounds from rotting. I use perlite in a PAPER bag. Check in late January. If rot is evident cut, scrape and clean off all rot. Coat cut surface liberally with powdered anti-fungal or cinnamon pushed firmly into flesh. Let dry and store. >Soil Reqs: Slightly acidic (6-6.5) well drained, humus enriched sandy loam. Adding mulch to the soil will help maintain a constant soil temperature. This will help keep the plant stress-free. Mulch will also improve the texture of the soil and help hold in valuable moisture. Calla lilies thrive in well-drained, loose soil. >Pruning: Remove spent flower stems to tidy up your plants and strengthen leaves and corm. >Note: Watch out for Japanese Beetles. Hope this helps.

Hi Deanna, I'm hoping someone who's experienced your exact circumstance chimes in. One question. Was your Calla exposed to temperatures in the 30's? I typically plant my Calla tubers in mid May, in ground and pots, and lift in Autumn just before or after first frost. Storing dry is very easy so I don't consider these annuals by any means. I've never purchased a potted Calla, in bloom or not, so an early dormancy isn't something I've experienced. My GUESS is by keeping yours indoors until your outdoor soil temp is in the 70's and after last frost you can get it to break dormancy. I'd keep it on the dry side until you've got new growth. Then normal Calla treatment. Lots of water, regular feeding and part sun if potted (or daily watering in full sun). If in ground, full sun with a good cover of mulch to keep the roots cool and wet. Are the leaves sword shaped, lanceolate?

I am up in Canada and have the Voodoo Lily a number of years I had originally one bulb but now several A few years ago I tried a couple of the bulbs outside in a sheltered spot and not only did they survive but bloomed. Stinky rotten meat smell, was the bloom, and lots of flys around it but it has a striking flower The other bulbs I have in large pots that I bring in over winter and put out in mid May. They make striking foliage all summer but I never get the flower from them
