I have had a pot of calla lilies that i put out in the spring and take into garage in fall. This year I got beautiful healthy green but no flowers. Is there something I can add to the soil now to help next spring?

There have been many questions this year about plants not blooming. One has to wonder if weather has something to do with it. The first thing that comes to mind for you is the pot. This fall or next spring, slide the rhizome out of the pot. It may be too large for the pot at this point or the potting mix, which deteriorates, may need to be replaced. It is hard to keep roots from over-heating in pots when plants need full sun. Perhaps avoiding terra cotta and pots with dark glazes will help. Mulch the top to lessen sunlight/heat to the soil and help maintain consistent soil moisture. Try a fertilizer with less nitrogen than the one you are currently using. e.g. instead of 10-10-10, try 4-10-4. I've included an article on dividing calla lily. https://www.gardeningknowhow.com/ornamental/bulbs/calla-lily/dividing-calla-lilies.htm
