Hi Aaron.
to NGA
Plant them now. Its a little late but next spring will be really late.
How big are the pots? I would think 3 bulbs would need at least a 12 inch wide pot. Callas do go dormant in the winter so be prepared to winter them over somewhere cool and dry OR lift them and store them in the refrigerator in peat moss until next spring. They need 3 months of dormancy.
