I have had a hosta for years that is usually a fasbulous, full and healthy plant each year. However this year I noticed the leaves were drooping and the edges of the leaves were a yellow colour. Some of the leaves had holes eaten in them. So I spent days & evenings popping out and checking through the plant and I found 1 vine weevil in the plant. I remamber my mother having them in her garden years ago and telling me they had to be stood on to get rid of them. I have since found 2 more vine weevils beside the large pot the hosta is in. What can I do to save the hosta? And is there any other way of getting ris of the vine weevils?

You might want to use the Nemasys biological control, or Provado which is a chemical.
If when potting all plants in pots, indoor and outdoor, you use half to two thirds unsterilized garden and half compost, there will be few, if any, vine weevil larvae found.
