Starbucks and Peet’s Coffee Grounds for the Garden
Do you remember Starbucks giving away prepacked bags of used coffee grounds for the garden? When we began using them, our roses started blooming beautifully. Now, we throw coffee grounds in our vegetable garden too, and our tomatoes love it!
Sunset Magazine commissioned a study about gardening and coffee grounds. Used coffee grounds contain high levels of potassium and phosphorus, and they produce nitrogen when they degrade – all of which help plants thrive. I’ve read elsewhere that spent coffee grounds also apparently deter slugs and cats, whereas worms, which amend soil, flock to it like candy! We add it to our compost bin, but we also spread it around like mulch in our garden.
The next time you go to Starbucks – ask for a bag of grounds for your garden. Christi Earhart at Starbucks (in the Raley’s Shopping Center) suggested that customers bring in a bucket with their name on it that the staff can fill throughout the day. What a great green idea!
I recently read an interesting NY Times article online about BTTR Ventures; two UC Berkeley grads founded BTTR Ventures (pronounced “better”) and began using Peet’s coffee grounds as an integral part of their mushroom business. They sell their mushrooms (available at Whole Foods in the Bay Area) as well as mushroom kits (I’ve seen them at Peet’s in the past).
Peet’s also has an article on their website about gardening using their coffee grounds. Every time I’ve gone in to Peet’s at Quarry Ponds without my hubby, one of the guys has offered to carry the coffee grounds out to my car for me. How great is that?!
Try it out – and let me know whether you think it makes a difference in your flowers and plants.
Happy Gardening!
