_Posted by Helena on 2025-01-15_

Do you think this is a fungal disease on my Hoya Obovata? At first I thought it might be sun-stress as I had moved it under grow lights. But now I am thinking fungal. If so what is best treatment?

Looks like fungus! Arbor has a fungicide! Although I’ve never had to use it so maybe others have a recommendation for that.

I haven't tried the Arber fungicide, but loving their pesticide, and I've heard good things. I use Growsafe lately, it's both fungus, mold, pest, mites.

Have you checked the roots? Just a thought - It might be worth loosening the plant from the pot and taking a look there first. Remove any damaged roots, rinse the remaining with a mix of peroxide and water, and then repot with fresh soil.

I used the Arbor fungicide.  
What should I expect? Spots go away or just no additional spread?
