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,
lol



Get a large pan and fill with water, create an island in the middle
and stand pot on it, the water gap will stop them as long as its
over 2". make sure the pot is not in the water.
Spray plant on dry evenings with a liquid slug & snail killer

Good idea thanks, theory is sound but not practical - this is about
an 18" tub, I'd need to be into landscaping a pond to put it in.

Just found reference to copper strips as a barrier, does that really
work, or simply a cash crop at garden centre tills?

lol


It is supposed to work. it might be interesting to try a band of copper
separated by a few mm from a band of aluminium foil (or a strip cut from a
tin) round the trunk. A snail crawling across should cause a voltage to
appear across the different metals, and that should be enough to dissuade
it. If you do try it, please let us know if it does or does not work.
