Coffee Grounds are great for Hydrangeas, Camillias and Roses!

Put your Used Coffee Grounds to use in the garden.

Don’t throw out those used coffee grounds.  There are lots of ways to put them use in your garden.  And more to the point, there are certain plants, such as hydrangeas, Camellias and roses that just love them!Don't throw those used coffee grounds away. See how to use them in the garden! thegardeningcook.com

So you have brewed yourself a big ole cup of Joe and have a pile of used coffee grounds. What do you do with them.  Well, you know me, I just don’t seem to be able to throw away  kitchen refuse, if it can be used in a compost pile, so that is the least that you can do with them. save the grounds from your morning coffee for your garden

But there is no need to wait for them to compost.  Used coffee grounds work great right away but just digging them into the soil near your nitgrogen loving plants for some extra nourishment.

This works especially well camellias, hydrangeas, and roses. Not only will you have healthier plants, but you will also save money on garden fertilizer, and know that you are being “green” as a gardener. Hydrangeas and other acid loving plants like used coffee grounds

Blueberries, cranberries and other citrus fruit like used coffee (and tea) grounds added to their soil since they help to bring it closer to the 3.0 -5.0 PH that these plants need.

It is not just nourishment that used grounds bring to the soil though. There are a lot of other benefits:

Deter bugs.  Coffee grounds are also known to deter slugs and snails, so sprinkle them around plants that these pests love, such as hostas and broccoli and Brussels sprouts.  They are the perfect organic DIY snail deterrent.Used coffee filterLiquid feeder. Coffee grounds make a great liquid feeder.  Place a handful of coffee grounds into a bucket of water and leave them for a day or two.  This will create a nice amber-colored liquid that you can use to feed house plants as needed.

Greens for the compost pile. I also throw my coffee grounds, filter and all into my compost pile.  They are considered a “Green” component.  Coffee grounds an excellent garden source in this regard, as are many vegetable scraps, egg shells and other kitchen refuse items.   The coffee grounds have a 20 to 1 ratio of nitrogen to carbon, which makes them ideal for helping grow plants such as tomatoes.put your used coffee grounds in the compost pileMulch for plants.  If you have acid loving plants, some gardeners say to forget the mulch.  Just pile up the grounds around the plant to keep the weeds away. (I would add them to other lawn refuse such as grass clippings or leaves.).

Where to get used coffee grounds.  Some coffee places such as Starbucks will give away their used coffee grounds if you just ask.  So make friends at your local coffee house if you need more than you have at home.

Vermicomposting. Do you vermi-compost with a worm bin?  If you do, worms LOVE used coffee grounds for their food.

    Truck drivers have continually parked on a piece of private property that I got approved by tge owner and the City of West Valley in Salt Lake County to turn it into a garden. Ten trees are being delivered to me in the fall from Arbor Day Foundation. I called the cops last night and they said I can have the trucks towed away. So I put out a NO TRESPASSING sign last night. Have to check on it now.

    Thanks for the tip! I’ll have to use my coffee grounds around my roses. I’ll have to look into my laurel bushes would like them, too. (I am trying to encourage them to grow into a privacy hedge.)

    chop up banana peels & add to your coffee grounds, I did this & some of my roses that always have 2 or 3 blooms on them, are blooming thier butts off.9 that’s what my 5 yr old Grandson says.

    Coffee grounds are long known to enhance azaleas. They love acidic soil and coffee grounds provide the acidity.

    Can you use them for azaleas too? We planted 3 in our front yard by the steps, but one has died, the second is barely holding on, and the third is okay, although not as big as she should be. And my hydrangea is all but dead. We don’t have much shade in our front or back yards. Our house faces NE and it’s SW on the back. We put it in the shadiest place we could find, but I’m not sure it’s right for it. Any help you can give us will be GREATLY appreciated.

      Have you considered planting a few shade trees? Azaleas & Hydrangeas prefer shadier areas. The Arbor Day Foundation has a great website with LOTS of info about varieties of trees. Remember to consider the rate of growth and the size it will be at maturity. In the meantime, what about creating some type of summertime awning using cheap canvas drop cloths draped over a DIY pergola to add shade to an area?

      Try to put up artificial shade if possible until you can move your plant. I had a hydrangea off my patio which had sufficient shade until wind took out two large limbs in my neighbors maple tree. I put my patio chairs around and up over my plant to help shade during hottest part of day. I plan on moving plant later this fall or early spring. Hope temp. shade helps.

      Do what I do if you have no shade trees. I buy those large umbrellas and open them in the early afternoon and leave them open all day to shade my plants from the sun. Put the umbrella close to them so they will get a lot of shade and close the umbrellas in the evening. But you really should plant some fast growing shade trees not only for the plants but to shade the house and cool it off. Save on the electricity. The more the merrier.

    Thanks for all the comments everyone. Basically all acid loving plants can benefit from coffee and tea grounds.

    Isn’t it great to use things that would normally make it to the trash to make something grow better?

    I have a question about hydrangeas. The coffee grounds do work really well. I would love to cut the flowers of my hydrangeas but I am worried they won’t bud back again. Would they?

    • admin
      06/19/2013 at 9:52 am

      It is best to cut them before august to insure that you will get blooms next year. If you cut them after August, you may cut of buds that have formed for next year’s flowers.

      Hi Barbara,

      Each animal is a bit different. Once they discover the garden and how tasty it is, it is very hard to keep them out short of fencing or caging or netting.

    Can this be done for all plants? Will it be beneficial for herbs as well? I am having a really hard time trying to grow my first plants in pots, lavender isn’t doing great, and thyme also.. Seem like they are dying. Something is eating away at my mint and basil leaves although they are flourishing… Thanks to any advice!! Lauren

    • admin
      05/31/2014 at 11:57 am

      Hi Lauren,
      Yes, they will help herbs too. I’ve never tried to grow lavender but thyme grows easily for me. If something is eating your mint and basil, it’s likely caterpillars. Inspect the underside of the leaves to see if you can find the critter. Sometimes they are green and sort of camouflage themselves.

    Hello all, I have hacked a flower garden out of my tiny backyard. An eclectic mix of flowers that are native to my area. No room for a compost heap. Thinking of purchasing earthworms to improve the soil & using coffee grinds to encourage the earthworms & perk up my roses. Does anyone know if the coffee grinds will help protect my sunflowers? I do not use pesticides because of my cats. Something is eating on my plants :(
    Thank you

      Hi Beth Plain composted (rotted) coffee grounds make excellent fertilizer. they have a natural anti-fungus effect and also help keep the soil moist. No extra benefit for sunflowers that I know of. Carol

    My roses and hydrangea’s are fed a steady diet of coffee grounds, banana peels, egg shells and green and herbal tea bags. I also add some organic matter once a year, like worm casings, kelp meal, epsom salts. Oh and some alfalfa pellets. That’s it and they thrive like crazy.

    Does the coffee grounds have to be used or can they be new right out of the can?

    • admin
      04/19/2015 at 9:40 pm

      Hi Betty,

      You can use them new but this would defeat the recycle idea of reusing them. Carol

    I’m new to the whole planting experience..I live in the city but, I’m still a country girl at heart. So, I have many 5 gal containers that I’ve planted – I have 9 total of tomatoes with 3 different varieties, 2 pepper plants, 2 eggplants, 2 cauliflower, & 2 broccoli. I was wondering if I could use the coffee grounds on container plants also or if this would be an issue. I’ve never planted anything before and I think they’re doing pretty good so far. Thanks for any help or advice with this.

      06/13/2015 at 1:46 pm

      HI Barb. The coffee grounds are really more for plants that liked to have a more acid soil such as the hydrangeas , camellias, berries and roses. I don’t think I would use it on vegetables.

    I do, in fact, use tea grounds as well. It’s funny how organic waste could help your garden in many ways, and I sometimes feel like I should go around and collect it from my neighbours and use it in my garden, haha! When I’m not lazy I also collect eggshells and use them in pots(since it would take too much time for them to have any impact in the garden).

    Regards, Rosie

    my daughter lives in Indiana and has never planted hydrangea’s. she loves the white and green colored hydrangas. she has planted Annabelle,Snowflake and Lilli Hydrangea’s. and we were wondering if the coffee grounds will change the color? and the banana peel and the egg shell will that mess with the color? what is a good fertilizer for these white Hydrangea’s? thanks so much, Sunnie

    • admin
      08/05/2015 at 10:51 pm

      HI Sunnie, One thing I have learned about hydrangeas is that the color comes and goes. Mine were peachy colored one year and very blue the next. I did nothing to the soil at all. They do like an acid soil, and coffee grounds help with that but I don’t know if it affects their color. Any kitchen refuse is fine for most garden plants. I don’t use any chemical fertilizers, so I can’t comment on that. Carol

    Can you use too much (many) coffee grounds? Can you use them year round? Thanks!

  21. Carol
    11/06/2015 at 9:56 pm

    Hi Carrie,

    I would not put them into the soil near the same plant over and over. I would alternate between plants and perhaps not fertilize during the colder months when many plants are dormant.

    I have some potted roses on my windowsill, one is actually quite large. I occasionally add a spoonful or two to the pots (much less for the smaller ones). My question is how often can or should I add coffee grounds to the soil in potted plants? How often can you put coffee grounds on outdoor plants like hydrangeas or rhododendrons? Thanks for the information!

    • Carol
      02/15/2016 at 11:01 pm

      Hi Stacey, I have never used them on potted plants so I would not know how much to suggest. Out side in the garden, I’d suggest 1 tablespoon of coffee grounds around each plant, lightly working it into the soil once a week.

    • Carol Drescher
      06/10/2016 at 11:36 pm

      I had planned on using coffee grounds around a hydrangea bush but how much is enough, or too much?

      • Carol
        06/11/2016 at 3:33 pm

        It is hard to say just how much. Most people just sprinkle them around the plant. I have read that a suggested ratio is 1 part coffee grounds mixed with 3 parts dried leaves and then place around the plants. Carol

    I use an empty coffee can close at hand when cooking and dump everything in that like I would do for a compost pile. It’s easier for me to handle (can’t turn an compost pile). I date each can and make sure I use the oldest first. I use a couple of large scoops to make ‘tea’. Also I use a used coffee filter in a colander to strain my tea.

    • Carol

      Hi Jane, I have never tried flavored coffee grounds, but I doubt it would matter. Clematis likes lots of nourishment and coffee grounds are often recommended for it. Carol

    When I learned this I started saving them from when we meet in the lounge for coffee every morning. Have 5 rose bushes and the fellah whom told me I could plant one of my roses in his garden also has growing 3 tomato plants so he told me to put it around them too. Then where I got my drift rose this other woman whom I know has 2 hydrangea plants growing there as well so will ask her if she wants any around them. So often do I put it around them and how much? I also have to mix it in with the soil right?

    • Carol
      07/27/2016 at 10:18 pm

      Hi Karen. The grounds break down in the soil. I would just alternate it between bushes and give them a rest in between. Not something to do all the time, any more than you would fertilize with commercial fertilizers often. I’d give it a month rest perhaps. Yes. Mis it in with the soil. Carol
