We have a 2yr old weeping Caragana Arborescens in a large pot in front
garden, and snails are determined to killl kill kill.

It's a case of picking off 20+ every night, and last year they succeeded
in destroying all new shoots, and bypassing a cardboard collar I fitted to
stop them climbing up.

What other ideas to stop them do you have?

thanks,

Why cardboard?

Solid copper collars work very well - not 100% because they travel under as
well as overground.
