  1. I have been a very successful gardener. I am not bragging. I still grow an amazing quantity and quality of wholesome organic food.
    Btw. I am that “weirdo”:) who just left a civic meeting with a trash bag of fresh coffee grounds in tow.
    50 people, drink a lot of coffee. And, love the produce I often bring with me. A calling card, if you will.
    At the property I am living on presently, I am not “there” yet.
    I had an epiphany, very early on. I really do not think about specific plants that do well, or not, by “throwing” coffee grounds down on them.
    I only think about soil (the mineral dirt, and the life within the soil) health.
    Healthy soil makes my thumb’s green. I can be a dweeb in the garden regarding plants, plant care, but with very healthy soil, I nevertheless, have great success. People far smarter than me are on Quora. I am just an amateur pedologist, soil scientist, with green thumbs as a result.
    I have incorporated probably well into the 1000’s of pounds of spent coffee grounds into my soil.
    I “had” and still have clay soil, though it is far more loamy now. That loam that is so great, carrots and dandelions both grow roots very deeply, it’s spongy and drought resistant.
    Where I have intensively amended it, it feels like walking on a sponge, if I venture off the wood chip paths.
    Carrots and dandelions can both be pulled out intact. Whole roots.
    Coffee grounds are very good for introducing more organics to you soil. They are small in size. Break down fairly easily. Worms love them, as do fungi (a good and bad thing). And, they offer trace minerals and moderate nutrients to stimulate growth.
    Coffee grounds are “bad” piled up. Close to seedlings in particular, they can create a substrate for fungal diseases, that can kill your seedlings. In fact, once sterilized, I grow edible mushrooms in them. The edibles have to outpace the “nasties”, molds and mildews.
    There is a myth about increasing acidity. Spent coffee grounds have a minimal impact to modest impact on soil acidity. Meh.
    Here are three ways I use them for every plant in my garden.
    I compost many first. Adding them to my hot compost piles is the first way.
    In many beds, I dig them in, weeks to a season before planting. I let earthworms digest them first. Worm black gold comes out the back end.
    Worm poo. Or castings.
    I let the tunneling worms aerate, and fertilize my soil, later my plants, on a diet of coffee grounds.
    Here’s a scenario. I am rotating potatoes. I am preparing beds for them in October to be planted on St Patties’ Day, or reasonably close.
    The second way, I “bury” 2.5 gallons, half a 5 gallon pickle bucket, per planting hole. Filters and all. I let the worms incorporate, and let the soil rest covered until Spring.
    Bingo. Very loamy soil. Perfect nutrient balance. Add a bit of powdered sulfur to increase acidity. Plant my potatoes a week or two later.
    For individual filters full of spent coffee, I throw the coffee grounds across my ground.
    The third way is simply broadcast application of small amounts. Large sections of my garden are mulched. Sheet composted and cold composting. I put the filter paper, with a rip or two, right on or in a separate hot compost pile.
    My soil still needs organic amendment. I have put tons of compost on, and in it. I sheet layer a top protective woody and partially composted mulch to protect it, to keep down the weeds, and to prevent erosion.
    That’s my home for today’s coffee grounds. They were applied by broadcasting them across the garden’s woody chipped top layer, to let the rain wash them in.
    “All” plants love the finished product. Good rich loamy soil.

  2. Coffee grounds contribute to the acidity of the soil, so you don’t want to use them in plants that prefer alkaline conditions. Alkaline Tolerant Plants
    Among houseplants, as far as I know, they all prefer a certain amount of acidity.

  3. Hello no i would not think so lets look at what i mix up for acid loving plants in south florida which is every plant for the amount of sand down here. Ok. I use 2 parts coffee after use grounds 1 part epsom salt or u can spend money get magnesium sulphate and 1 part potash from charcoal or wood ash mix together and a 12 6 8 fertilizer or blooming plants with 5 10 15 it really makes things go spring thru fall it works great if ur planting flower beds or veggie gardens work into ur soil without granules but instead add bone and blood or just blood meal to that and ur fruits or veggies will reward u
