Will slugs cross coffee grounds to get to suculent leaves? Yes.

Another popular theory, debunked.

Exhibit A: a big fat slug in a styrafoam box with a kale leaf surrounded by coffee grounds.


Exhibit B: the same scene, about an hour later. The slug not only went for the leaf but managed to move it to the other side of the box.

For a list of all of my slug control experiments, please see this page.

It would be interesting to try the experiment again to see if the coffee grounds change the slugs preferences. ie, if there are leaves that are not surrounded by coffee grounds, does it eat those first? Or, if there are less preffered leaves, will the coffe grounds be enough of a deter it from the preffered kale?

That would be interesting. Perhaps I will try that soon. But for now my next experiment will be testing out beer methods and how to make them work best.

okay, so coffee grounds and DE don't work. Boo. Have you tried more coarsely crushed eggshells? I'm anxiously waiting for your beer trap results. Please let us know!

Definetely I want to try out crushed eggshells. :-) Will post when I do!

also doesn't work: ground egg shells. have you read The Truth About Garden Remedies, by Jeff Gillman? he's done a lot of experiments similar to yours. i've tried the egg shells anyway, and had no difference in slug damage.

I have read the Jeff Gillman book. It's been a few years but perhaps I should pick it up again.
