  1. Twice a day I take my used espresso puck and throw it into my roses or succulents or orange/lemon trees or bougainvillea...any plant. I throw it onto the base of the plant and just dig it lightly into the dirt. I make a pot of coffee...the same thing with the grinds. It is very very beneficial.
    The plants LOVE it. Any good compost benefits from coffee grounds...it helps to keep the soil aerated and provides a good acid base.

      Good to layer coffee & filters around house plants. Get some decorative moss to go around plants & then just lift up an area & tuck the grounds & filter in there & cover up again with moss.

      Toss in a pile if you don't have a compost bin & keep doing that until you have quite a pile & then just take a couple shovels of dirt & pile the dirt on top of the grounds & filters & keep on tossing. Water this pile often & pretty soon you will have some good rich dirt.

      You could also do this in a large plant pot..just keep layering & putting dirt & keep watering. If doing in a pot, use some good dirt like Miracle Grow or whatever. In no time you will have the pot ready to put a plant in.

    2. The local Starbucks gives it away in 5 lb bags.
      Good acidized for flowers.

        Yup, I've filled up the trunk of my car many a time with Starbucks grounds (trunk smells great!). Our soil is highly alkaline, so the acidity of grounds is a big hit. Plus, the acid-loving camellias love grounds. And, especially when I add cocoa mulch, garden smells great!

      2. I heard that worms love to eat it and therefore will hang out in that area of your garden, which is a good thing.

        1. I use quite a bit of used coffee grinds.

          I actually put a trash bin at my job site where they have coffee brewing all day, and designated it for used grounds and filters. So, at the end of the day I take a nice bag home. I'll sometimes throw a couple handfuls out into the garden and dump the rest right into my composter.

          I also collect the company's shredded paper once a week to combine in the composter for 'browns'.

          1. I've heard that coffee grounds are good all the replies here confirm that. Just a follow up question, I don't have a garden but hope to experiment with a few herbs and vegetable balcony planters this year. So far I just have a small potted basil pant, will herbs also benefit from this, and how much is too much?

              Coffee grounds provide both organic matter and nitrogen. Most herbs do better without too much nitrogen as it promotes rank growth and low flavor intensity. Use coffee grounds quite sparingly. Exceptions include most mints but you could make their normal aggressive growth even worse. Coffee grounds are best in situations were nitrogen and acidity are positives.
