At the Green Square Growers event last Saturday, my friend Sabena (and fellow G S Growers co-founder) gave me a bag of discarded coffee grounds.
Coffee grounds are a waste product for cafés and many home kitchens, but they are a very useful resource for a gardener.
As coffee grounds have a high nitrogen content they are a brilliant addition in your compost heap. They will not only help to attract earth worms (if your compost has direct contact with the ground) but will also help to raise the compost temperature – which speeds up the break down process.
Snails and Slugs
Apparently slugs and snails hate caffeine. Turn coffee grounds into a diluted liquid and spray onto your plants to repel those pesky intruders. Remember to reapply after rain.
Pumpkin, corn, zucchini and cucumbers are all examples of edible plants that require high amounts of nitrogen. It’s a good thing that coffee grounds are high in nitrogen – sprinkle the coffee grounds on the ground around these nitrogen hungry plants (or add into the soil before planting).
Very soon, you too will be asking café owners if you can have their wasted coffee grounds.
