    I have 16-18 jades I've been moving in and out of the house as seasons change. Two or three of them have developed black spots on the leaves. They're maybe a quarter to 3/8ths of an inch in diameter and are a little fuzzy, with white matter surrounding their perimeters. Does anyone know what this is and what I can do about it? Thank you.

    It does look like mold, doesn't it. Thanks. Any further suggestions on a fungicide?

    I use a copper based fungicide, but I'm sure any would work. For a home made fungicide, I have used cinnamon, I use it when cutting the tap roots of my adeniums to prevent root rot, but just the powder, I imagine mixing it with water would work, but I couldn't give any ratios...

    Now I think we want one. Came to mind after reading this. We want to get live plants going inside again. I used to grow Jade Plant back when I was like 20, years ago. Never had spots like that though.

    Do you grow yours where the humidity in the room is substantial?
