Good morning all, one of my Achillea's is not doing so well and I've just found it covered in tiny bugs. I'm wondering why my other one are fine. Thanks

yes its a type of aphid. keep an eye on the other ones and spray them with liquid soap solution. if you see any ladybirds else where in the garden move them across to this plant. If they are hungry they will stay there and eat and hopefully lay their eggs.

Aphids you can just shoot them off with the garden hose.

Black fly with a vengeance. Type of aphid, so so whatever you normally do for aphid infestations. Liquid soap is as organic as anything else, but lots of ladybird larva are better.
