I moved into a home and inherited several roses last summer. Some struggled but were mostly pleasant additions to the garden. I noticed near the sick rose ants everywhere, and was told that the ants have a symbiotic relationship with aphids...that this might be the problem. Well I flooded the nest and the ants seemed to dissapear however, I am discouraged to find them near almost all of the roses this spring. they are in multiple garden beds, and I am concerned the healthy roses will weaken as the first rose did. The kicker is, as far as I could tell, no aphids! I havent seen an aphid on a single thing since moving in last spring. Im confused any help for ants and/aphids? My roses and I thank you.
