Garden Pick-Me-Up

Someone at work is collecting coffee grounds for their garden. How do I know this? Well, my super sleuth skills have honed in on the plastic container on top of the coffee maker with a label that says “coffee grounds.” If they are not for their garden, what else would they be for?

Actually, there are quite a few uses for spent coffee grounds—odor absorber, abrasive scouring and cleaning agent, skin exfoliant, and yes, cellulite reducer.

But, coffee grounds are best used in the garden. Here’s the why and how:

• They are a compost pile wonder. Just toss in, filter and all (teabags, too!) Consider them “green” not “brown” material (even though, yes, they are in fact brown), but they are full of nitrogen, which essential for plant growth. 
• Create a natural fertilizer by applying grounds directly to beds and working into the soil. Plants that prefer more acidic soil, such as rhododendrons, azaleas, roses and even fruit trees will particularly develop a caffeine addiction. Or, use this recipe to create a fast-acting liquid fertilizer. Dilute coffee grounds with water at a rate of ½ lb coffee to 5 gallons of water. Mix and spray!
• Rumor has it that grounds repel slugs, snails and ants. Chemical-free pest control!
• Use as a mulch in beds or containers.
• Amend your soil (pre or post planting) to improve the texture and pH, and attract worms.

So, stock up because whether you use your own, collect from the office or visit your local Starbucks, you really can’t have too much. (Note: I’m not entirely sure, but I think you can still go to Starbucks and take as much as you can carry. I’m sure any local coffee house would give away grounds for a good cause. Ask around!)

I’m not going to get into all the facts and figures about coffee ground waste in landfills. Just check out this page, which gets into the science, and sustainable and social causes behind grounds.
