How can I stop ants running along the trunk of my Japanese maple?
Our Advice
The ants are probably farming the aphids feeding on the plant. Spray the bush with an insecticide such as Sprayday Bayer Greenfly Killer'>Greenfly Killer from SBM to control the aphids. If the ants remain placing a Tree Grease Band around the stem to prevent the ants crossing over it. Ants trapped by the grease band will soon be eaten by birds.
