Composting with coffee grounds

I had the pleasure of writing a blog piece for the awesome Epic Gardening blog at the end of October (How to Compost with Coffee Grounds). Did you know that coffee grounds are great for your garden and add loads of lovely organic matter to your soil? They also have other uses in your garden such as slug and snail repellents or mulch around plants. No need to feel guilty about your coffee habit… your garden will love it!

Below are a few points about composting with coffee grounds from the blog piece. The full article is available here.

Can I add coffee grounds to my bokashi bucket?

Coffee groundsYes! Definitely! Adding coffee grounds is simple. Add the coffee grounds (and coffee filters) along with all of your other food waste once every day or two and sprinkle on some Bokashi Living compost accelerator (bran). Continue to fill your kitchen composter in the usual way. Enjoy great homemade compost in just 4-6 weeks.

But aren’t coffee grounds acidic?

Many gardeners are concerned that coffee grounds are acidic. However, studies have shown that much of this acidity is soluble and will therefore end up in your cup of coffee. The used coffee grounds are fine to be added to your garden without altering the pH. However, if you are expecting to add very large quantities of coffee grounds to your garden (more than 25% volume) you may start to see changes in the acidity of your soil… but that is a lot of coffee, even in a small garden!

Where can I get more coffee grounds?

Don’t just stop with the coffee grounds produced in your own home. There are lots more sources of used coffee grounds that people are often very happy to give you for free. Coffee shops and restaurants are a great source of free coffee grounds.

Starbucks are probably best known for this having introduced their Grounds for your Garden program in 1995 offering free bags of used coffee grounds to their customers. But just ask in any coffee shop and they are often more than happy to give you their used coffee grounds.

Why not add a can by your office coffee machine and collect those too?
