copper pennies around plant stalk to deter slugs

I read that some people were putting copper wiring around the base of their plant stalks to slugs wouldn't climb up and eat the leaves...

I didn't have any wiring, but figured pennies might work...the pennies that were minted before 1982, since those ones are 99% copper


I still had a slug on one of my plants this morning...I'm not sure if it was there before I had put the pennies around the plants though...


Anybody else do this, with success?

i would stack up the pennies so they all touch.

you can get speaker wire and strip the plastic off the outside.

boom. copper cables.

copper has worked decent for me this rear i use wire though. the only probs is branches touching the ground especialy after heavy rain.
