Dear Vicki,

Thank you for contacting Ask Extension about your snake plant. Plants that receive either too much or too little water often look the same because in both cases they are unable to deliver oxygen and nutrients to the foliage.

It is possible that your plant may recover if the roots are not totally affected by the root rot. The plant will need to develop new roots, so keep the soil evenly moist (not too dry or too wet.) Make sure there is excellent drainage from the pot, and do not allow it to sit in any excess water that drains out the bottom.

You may already know this, but best practices no long recommend placing any drainage materials (stone, pot shards, etc.) in the pot since this actually prevents the excess moisture from draining out. I generally recommend using a pot with holes and placing it on a trivet over the drainage dish. 

I hope this information is helpful and that your snake plant recovers. Please write again whenever you have questions.
