Hello, my speedwells looked so healthy and flowered beautifully their first round of flowers. When I deadheaded them to encourage a new set of flowers I noticed they appeared to have some black spot on their leaves, like I've seen roses get. Can speedwell get black spot too and how can I prevent it from getting worse? Thanks!
