Garden help needed- ants in roots of coneflower
I have a coneflower plant in a container on my patio. Today, while potting it up, I noticed tons and tons of black ants around the roots. I think they're living inside the root ball, but i'm not sure. I don't have any ant colonies on my patio, so there's nowhere else for them to be living.
Are these ants a problem? Will they harm my coneflower plant? If so, how should I treat for them without harming my plant?
Thanks so much!
