GUNNERA OVER WINTER

What you do is in the autumn before the first frosts, break or cut the leaf stems (or bend them if they'll go) over the crown of the plant. This protects it from the cold. If you are in a very cold area, pile straw on top as well. Leave them there until the spring, then uncover and dispose of the leaves. The new shoots will be appearing. I remove the old soggy flowers and generally have a tidy-up, too.

Great, thanks

I think you should let it sleep peacefully, ready for all that energetic enormousness in its growing season! Maybe a few gentle lullabies?
