Garden With Coffee Grounds

Love your morning cup of coffee? I sure do! Don’t toss those grounds from your morning cuppa in the garbage or down the disposer! Instead, put some zip in your garden with coffee grounds.

Why would you do that? Actually, coffee grounds have a lot of benefits for your garden. They can help amend soil texture, add valuable nutrients and even feed your compost – worms love them.

And that’s not all. There are some natural fungal colonies on coffee that seem to suppress some of those common fungal rots and wilts. These bothersome rots, include Fusarium, Pythium and Sclerotinia species, which cause yellowing and wilting of the leaves and eventual plant death.

How else can you garden with coffee grounds ?

Here are some suggestions that gardeners have found valuable.

  • Sprinkle them around your fruit and berry plants as mulch or top-dressing. Nitrogen lovers like tomatoes, your green leafy veggies, blueberries, roses, camellias, and azaleas will all benefit. Keep the grounds to about a quarter inch in depth, or they may get mouldy.
  • Use them as an amendment to clay or compacted soils. Not only will they improve the tilth and soil drainage, they’ll add organic matter. Dig them in well.
  • Layer them between straw or grass clippings if you’re building a lasagna garden. Believe it or not, worms seem to love coffee grounds, so you’ll be attracting these little friends upward into your new garden bed.
  • The carbon-to-nitrogen ratio of coffee grounds can be as low eleven to one, an ideal ratio for plant and soil nutrition. Sprinkle them alongside your garden crops for a slow release fertilizer.
  • Add them to your compost pile. That ratio mentioned above makes them a ‘green’ element in the compost. Dig them in well, since they tend to clump up.
  • Soak the coffee grounds in water for 24 hours, strain, and use the water as a foliar spray. The nutrients dissolved in the water will boost your plant health.
  • Problem with slugs? If you garden with coffee grounds, they’ll help deter those slimy little pests. The grounds are scratchy, so the slugs don’t like crawling over them. So place a circle of coffee grounds around any plants that are slug-magnets.
  • I haven’t verified this one, but some gardeners claim they also repel cats that are using your garden as a big litter box. Wish I’d known that!


What can you do if you’re not a coffee drinker?

One of the best tips I’ve read is to ask your local coffee shop if you can collect their grounds. If they agree, give them a 5-gallon container to dump used grounds in, and collect it regularly. Some coffee shops already have ‘grounds for your garden’ programs, so check with your local coffee shops.

So there you have it –are you ready to garden with coffee grounds?
