Bugs (maybe thrips) eating dahlias - what to do?!
Hello, I am seeing advice oh how to treat one of my dahlia plants for a bug infestation. The plant's blossoms are coming in deformed because of an infestation of little black bugs, possibly thrips. They are only attacking one plant and I have tried to cut away the affected blossoms, but they keep coming back. I've been trying not to use any chemicals on them but I am ready to do whatever is necessary before it spreads to other plants. I have included pictures of the bugs and the damage. I would be so grateful for any advice you can offer. Thank you! Andrew Billi 911 Gott St., Ann Arbor, MI 48103
