I had Calla Lily bulbs planted in planters and some also planted in the ground. We have had so much rain lately so I decided to empty the pots of Calla and discovered some of the bulbs are rotting. Then I decided to dig up what was in a raised bed and some of them were also rotting.

My question is can the bulbs be saved it I clean them up and dunk them in a solution of bleach and water? If you have a better way of dealing with them, please let me know. Thank you in advance.

Same happened to me last spring when I potted them earlier than I should have and over watered them. Took garden hose with a jet type nozzle and sprayed off all soft parts. Let them sit in dry area under house with no soil. Month later, when warmer, placed them in pots with no soil covering their tops, all started growing, planted all in garden and they flowered. Did not use any chemical solutions.

Calla Lilies don't like wet soil or poor drainage. If the bulbs are starting to go dormant and there's been lots of rain, they will easily rot. I would just salvage the ones that aren't rotting as there's not much you can do with the rotting bulbs. You will need to dig them and store them for winter any minute now anyway.

Thank you Steve and Daisy. I did hose them off with a nozzle sprayer and put them under the deck on a picnic table and let them dry. I'm so glad you commented because it reminded me that I need to bring them in because we are going to get our first frost very soon, and I don't want to leave them outside. Now I will inspect them to see if there are any other soft spots on them and get them ready for winter storage.
