I don't know if your plant healed itself. If it did you got lucky. I would google broadmites on african violets and read all you can. There are a lot of articles on it within this forum also. Good luck! Rosie

Rosie, thanks for the information. my plant didn't look as bad as the one in picture. if it is impossible for an AV to recover by itself. maybe it didn't have mite. May it's other issue.

You're welcome and good luck! Rosie

It's not impossible it can recover on it's own. There are several things you can do. Take leaves to wash with soap and water and restart the plant, discarding the old. Or you can spray it with a quality miticide like Forbid, then dome and isolate it from the rest of your collection. But the best thing you can do for any plants you think have mites is simply BAG THEM. Raising the humidity substantially is quite enough by itself to kill off the mites, oddly enough. It also promotes the proliferation of predatory mites that feed on broad mites and other forms that would feed on your plants. No miticide required in that case but for best results, I do /both/. Spray the plants and bag them for at least a month (three is better because mite life cycles hatching from eggs can take 6 to 8 weeks.) Doming may be sufficient but only if the humidity can be kept high, which isn't always easy if your domes aren't well sealed. If the crowns are lost, the plants will produce suckers which you may then remove and pot up later, faster in some cases than restarting from leaves but not always. Good luck and remember to shower and change your clothes after handling plants you think are affected - it's easy to spread the mites and not know it. Washing your hands helps but isn't enough if you happen to touch your clothing.

Hyn,

Thanks for the information. Glad to know that humidity can control mite. I finally treated the infected plant with forbid and removed the crown. It pop out several suckers quickly. Some of the new leaves are curl down and brittle. So, I patiently waiting for it to give me some normal sucker.
These mite seems like covid, need to wash hand and take shower after exposed. 😅
