Ceres Cactus Leaves Turning Brown On Ends…

Question

Please help….some of the older leaves & now a newer leaf is turning brown at the ends…?

I know it got over watered this summer (plant sitter) but now its back to only every 4-5 days (its potted)….

Answer 1

Once it gets overwatered, it must also be treated for infection. It will happen, almost, always once overwatered.

Only correcting the watering habits still leaves an infection that will continue to worsen, and grow inside the plant and soil.

Correcting with a fungicide will be your first line of defense. This article will help:

Once you take care of the infection, it will start to recover, but probably quite slowly. New growth will come out clean once the infection is gone. Old growth will not recover, but will not spread.
