My only point is this little experiment is to learn if "spent" coffee grounds repel slugs and the coffee grounds in pots as a weed barrier.

They have a small charge of N and are an excellent source of organic matter and usually free. The fact that worms seem to like them proves the organic process is working and when it is we have little to do except water and figure out how to kill the slugs.

And I still remember when some 40 years ago and I was a 23 or so year old princess, when I got someone to save me coffee grounds and I put them in my beds ( wasn't growing hosta at the time) and my FIL the farmer told me I would ruin my soil with all the oils in the grounds....and...I BELIEVED him and stopped adding coffee grounds to my beds.
Oy....we get so soon old and too late smart.
