These are loved by slugs and snails and we grow them inside large rings (or two rings joined together for large plants). However, once the leaves get going, some hostas are so low growing and pendulous that they grow over the ring and touch the ground on the outside of the ring. This will make a bridge for slugs and snails, so we trim the long lower leaves back.
These can be protected with a ring around the base of the plant or you can stand the whole pot inside a Slug Ring.
Climbing plants such as clematis and sweet peas need protecting with small rings when they are young. Make sure that any training poles are inside the ring.
