Coffee Grounds and Gardening with Slugs
I had a new gardener tell me of her slug controlling exploits in the garden using coffee grounds and pouring coffee around and while I didn't exactly tell her she was wasting her time spraying yesterday's coffee on them to "kill them", I didn't exactly tell her she wasn't.
I took the road of least resistance and gave her this url to read. This is hard data from experiments on slugs and coffee grounds. And even if this used material doesn't kill slugs (it might deter them a little) it can and should be used in the garden.
Which is good news because I surely like my morning coffee.
And the rock beside the pot is a long-ago Father's Day present from some kid I know. :-) Where else does one put a rock ?
