I remember seeing someone burn his on a Gardener's World programme a few
weeks ago. If you decide to set fire to yours now, do remember that
hedgehogs often choose to hibernate in them.

Don't burn the Pampas now! The dead leaves from this year's growth will
protect the new shoots from frost. Burn off in March and new growth should
come through sometime fairly soon afterwards. Cutting back now will just make
the plant look tatty (in my opinion).
