No wonder they are such survivors - I have a sneaking admiration for
their persistence! I've given up on putting the plant in the
conservatory - it will go back to the greenhouse. I'll root a cutting,
and grow that on - in ant-free compost!

I have always used Nippon liquid, a few drops on a piece of slate or
glass or even a plant label placed where they are running.
It's never failed for me
