Coffee Grounds???

I hope i'm not posting a redundant thread, but the search function is the one thing on this forum that leaves something to be desired.

Anywho, I have heard that using used coffee grounds is great for adding pretty much everything the plants need, such as nitrogen, potassium, phosphate, caffeine, etc.

My question is, has anyone tried using this? if so, pros? Cons? Ratios?

I know my great grand mother swore by it, and she had a pear tree that grew some of the best pears known to mankind, but not sure how it would fare with my ladies.

Thank you in advance for any advise and suggestions.

It isn't strong enough to be the sole fertilizer, but it works great as an addition to your soil. I like to feed it to the worms in my bin, and then use the processed worm poo.

If you want to mix it into your potting soil use it at 5-10%. You can go up to 20%, but I didn't notice any benefit to adding more than 10%. Make sure to mix it in well to make sure that you don't have pockets of just grounds.

thats cool,,,, i'm wondering if the grounds are too weak as a fertilizer, what if i diluted some brewed coffee (cooled down to room temp of course).
Any thoughts?
