Hi Gents,

We have coffee machine at the office and we gets tons of coffee beans leftovers.

Did anyone tried before those leftovers as fertilizer??

Is that OK to try it??

On tropical fruits seedlings

I make slow drip coffee and put all my used grounds around all my trees and potted plants. I believe they will break down and will release some nutrients. They may also deter some insects and lower the pH slightly.

I think coffee grounds is high N I mix with a little bone meal and give to my plants which seem to love it tilled in to the first couple cms

[amitzauber]

can u plz tell me more about this mix??

[stuartdaly88]

Just 1:1 bone meal and dry coffee grounds couple handfuls tilled into the soil arounD the plant artichokes, tomatoes, roses and cape gooseberry really seemed to like it a couple times a season in addition to regular fertilising. When I had a rabbit hutch and used their pellets at the same time as the bone meal grounds mix my plants have never been happier.
I used to work promoting delonghi coffee machines at this time and had unlimited grounds.
But the grounds also make a good edition to compost heaps:)

At the very least, they're going to add a little organic matter and make the soil less alkaline--both good things.

I regularly use spent coffee grounds on all low PH loving plants, blueberries, Citrus, Miracle Fruit, Jaboticaba. It's free low dose fertilizer that many coffee shops will have waiting for you if you ask about spent grounds. I see a positive response from everything but the Miracle Fruit which I can't seem to figure out exactly what it wants, or I don't have those conditions anywhere.

Ants also run away from Coffee ground,

You can go to any Starbucks and ask them for coffee grounds and they will gladly give them to you.

I mulch with spent coffe grounds from my coffeemaker and Starbucks.  However, I'm debating whether I should continue doing so, because pesticides are heavily used growing coffee beans
