I was out in the garden the other day and noticed that my stonecrop has black spots and they aren't doing well. I have about 20 of them and three are "infected". I suspect it is mildew. Would you yank the infected plants and start over?
I've mixed up a bottle of water, bakingsoda and dish soap to spray on them but I'm wondering if that will really work. They all have nice new growth at the bottom, but I don't want to risk the plants next to these getting the same stuff.
any thoughts as to what you might do. I might post a picture, but it take forever for me to download, resize, up load and all that....I'll see.
