Rust on Pelargoniums- Anyone have results with corn meal?
I've had a fungus on my pellies this year. I think it's rust. It starts with rust colored spots on the underside of the leaves, then yellow discoloring shows up on the top side of the leaves. Doesn't appear to be killing plants, but sure is unsightly. We had a very wet spring, and that's when this started.
I've cut affected plants back severely, and am picking off affected leaves. Also washing hands between plants. But that's getting putsy, and this keeps coming back. I read on another forum about using corn meal/flour to control fungus, so I am trying this. I just bought a bag of corn flour and liberally sprinkled it on the plants. I'm going to go out and shake the excess off, then water. (Our wet weather has ended, now we are actually quite dry.)
Has anyone else tried this? I'm trying to get my pellies ready to take cuttings for overwintering plants, and I'm hoping to not bring any of this fungus into my sunroom for the winter.
Also, does anyone have any idea if this fungus would be harmful to pet rabbits? I know this is a bit off topic for a gardening forum, but our three bunnies are partners in the pelargonium growing operation. They provide fertilizer in exchange for pelargonium leaves. Three or four pelargonium leaves is the bunnies daily treat all winter long. (The bunnies and pelargoniums live in the same sunroom all winter. It's a little slice of heaven in there when the snow is piling up outside. Cute bunnies, pretty flowers. Life is good!)
