Q

How do we get rid of butterbur – it’s all over the side of our garden? A

Butterbur (Petasites) is a very vigorous perennial that spreads by undergroun­d stems called rhizomes. It’s one of those plants that can regenerate itself if you leave even just a little bit of the stem in the soil so even if you dig it all up you will notice bits reappearin­g.

However, persistent hoeing will eliminate it or if you prefer you can cover the whole area with a thick mulch of bark or weed membrane that excludes light.

You will need to watch out for it appearing elsewhere in the garden and keep on top of it.
