Its a black mold i get it to

so, does neem work or general fungiside? how hard is it to get rid of it? my plants are indoors for now for prolly another month, it's still cold here. i want to keep them on heat mat and tented for extra humidity - which caused this to surface. but i can untent them and still keep them on the mat - would that work better?

I would untent them the mold is a sign of to much humanity. I clean it off by hand with very lightly soapy water and a cloth. Down here during the rainy season I get it the worst on my gardenia and it can be hard to get it off of that gardenia because its in the shade.

ok, did that already - put them on a heat mat untented - but now have to water ev day, of course...i'll xfer them into mix now - then it's a little less worry that they will dry up.

am having fun with croton cuttings this season - rooted may be 10 diff varieties. that is i tried to root more, but some did not take - had no heat mat while i was in fl. but still may be 70% took, so i am content for now.

thanks for replying!
