So the lady over watered one of my favorite plants and it started dying! I took out the ones I could, chopped off the infected roots and added some root hormone to the bottoms after spraying with neem oil. Have reported them in fresh soil, but looks like one has root rot again! The others look ok. Anyone else have this issue ever?

Sanseveria, tough plant. Should recover. Give well draining soil. Large pots can encourage root rot, only because the larger mass of soil stays moist longer when there is not enough plant to use the water.

The roots have been severely damaged by inconsistent watering. It is hard to under water, but easy to overwater this plant, especially when it is potted in garden soil in a large pot, as Sally wrote. A single episode of heavy watering will not cause root rot. Keeping it constantly damp will.

Root rot is not the same as having a fungus problem. There is no reason to treat yours with neem oil because the roots are not diseased. Pot them separately or together in a small pot in a very porous Cactus type potting mix. Keep the mix just slightly damp to promote new root growth. Good sunlight and warm temps will also help.

Ok thanks - looks like they're recovering but this one still seems to have fungus, killed leaf. But the rest of it is growing well - any ideas what I should do? Thank you

It will take several months before you can be at all sure about recovery. When these plants are kept too moist, they often develop watery, mushy, stinky leaves as shown in your photo. It is not a fungus, but you should remove it and keep the soil just barely damp.

Did you have any success with saving?
