Kalanchoe leaves look healthy but fall off when touched
I have a kalanchoe that has been doing reasonably well until a month or so ago when it started showing white powder all over. I did some web search and I found out that neem oil based fungicide would work. So I applied it 5 days ago. Everything seemed fine, until today we see that the bigger leaves simply fall off when touched. The plant has become very bare except for the really small leaves!
Any ideas what is happening?
