Just bought two bushes to plant by my caravan in Cheshire. Acid soil,
freezing cold for days at a time in winter. Have supply of bonfire ash which
I believe they quite like. Anyone know how I would propagate them?
I'm keen to have more but don't want to pay as they're a bit expensive (and
I'm mean).

Bonfire ash is far too alkaline for them. If you need to apply potassium
use the sulphate or nitrate salt (avaible from garden centres).

Layering in spring is probably the easiest way to propogate them.
