Snake plant white stuff
Hi i’ve had trouble finding out what this is and im not sure how to fix it. The main mother plant has these white stuff with a blackspot in them and it was killing the plant. I decided to cut the rhizomes apart and left with the little one on the right (first pic).
The main plant is indoors and left beside a windowsill with afternoon sunlight. I only ever water it every 3-4 weeks when the soil is almost completely dry
There were still some of that white stuff so i dabbed a cotton bud and wipe it off myself on the spots that had it. I left it to callous and after a few days the white spots returned again.
Not really sure what this is and how i can get rid of it. I wanted to clear this up before repotting it back into soil just in case.
Any help is really appreciated 🙏🏻🙏🏻
