I have a calla lily, which i seem to have overwatered. The leaves turned yellow and started to come off at their base. I repotted today and noticed, that almost all the roots were rotten. I removed the rotten roots, and the rhizome seems to be healthy, so I cleaned it from soil. However there aren't too many healthy roots, and the foliage is still large. How can I save the plant?
I see my options as follows:
- repot: since there aren't too many roots, it can't take up much water, and because of the large foliage, it is going to evaporate a lot. I'd probably need to reduce foliage. But I fear, that root rot is going to come back again.
- cut off leaves, dry rhizome and store until next year: the plant might not have had enough time to store enough energy
- put into water and wait until it regrows some roots, then pot: i have successfully saved some alocasias this way. But I'm not sure it works with calla's.
All the info i found about recovering from root rot online, seems to be clickbait.
