I have just finished reading an article from a garden designer that I haven't seen before and thought I would pass it on to you all.
What do you do with the spent/used snail shells??
If we have a year like last year with an invasion of snails and slugs then this tip might just help. Use the used snail shells as cane protection. Better/Prettier than the green rubber things sold in garden centers, and free!!
Hope this is useful. Good gardening.
