Ants farming blackfly on my cherry.
I planted a cherry "Stella" 3 or 4 years ago and have had a problem with ants/blackfly since. I have tried lots of organic remedies including : rhubarb leaf + soap tea as a spray, planting tansy, chives,mint to dissuade ants, a chalk-like powder around the base of the tree, grease bands (the ants just walk over the grease)...
As the tree seems relatively happy except for the leaf distortion, many blossoms this year, should I just leave nature to it now or will it ultimately harm the tree?
