How can I keep the ants off my stepover apple tree?
I'm looking for ideas on how to stop ants (and their aphid livestock) wrecking my little stepover apple tree.
In the past, on other trees, I have used those sticky bands around the trunk, which have effectively stopped the ants. But this is a stepover tree, planted last winter, and it has stepover support, ie a taut horizontal wire to train it along. The ants don't go up the trunk, they go up the supports and along the wire. At any given time there's a non-stop train of ants going to and fro fro. Both ends, and the tree is really suffering.
I've tried wrapping sticky bands around the wires and supports - just can't get them tight enough to stop the ants circumventing them :-(.
