Your Calla Lily can be planted outdoors and left year round if you live in zone 7-10. In colder climates, dig up after first frost and care according to points 1-3 above.
This is a really cool process called “Gutation”. Gutation occurs when more water is absorbed by the roots than can be evaporated through the leaves. It is a perfectly natural situation, but put a protective dish under your plant to prevent any water damage to your furniture.
Your plant has started its dormancy phase. Its time to start the process to re-flower it. Follow the instructions at the top of this page in “What to do when your Calla Lily stops blooming”.
Ask your favorite florist, garden centre or grocery store to contact their buyer and ask for Homestead Growers Calla Lilies. Our network of distributors travel through most of the US and Canada.
