Safe to say that you're probably here thanks to your love (or obsession...we won't tell) with all things coffee. Not only does it work miracles on doing humany things, but coffee is also a bit of a star in the garden too...check out some of the clever ways to use your grinds in the garden.
Before you load up on powders, sprays and other chemical nasties to keep the pests at bay, simply sprinkle your used coffee grinds around the base of your garden plants, the abrasive texture and acidity in the coffee makes a great deterrent for snails, slugs and even the household (or neighbourhood) cat.
Used coffee grounds add nitrogen, potassium, phosphorus and a boost of magnesium to the soil. If you grow acid loving plants like roses, azaleas, hydrangeas, rhodies, blueberries, currants and gooseberries coffee grounds could be your best friend. Mix your coffee grounds with dead grass clippings, brown leaves or straw to neutralize some of the acidity and then spread around your plants. Or you can dig them into the soil at a depth of 10-20cms. If you want to have the benefits of using coffee grounds without increasing the acidity of the soil you can rinse them with water once or twice more.
Carrots powered by caffeine? Carrots love the extra boost provided by using coffee grounds. When you go to sow your carrot seeds mix in a little dried coffee grounds. They’ll get a kick start and pests will be deterred too!
Used coffee grounds make great ‘green’ matter in compost since they are high in nitrogen. Throw it on the compost heap, the mixer or even the worm farm. Worms love the coffee and will be drawn to your compost heap and if you have a worm farm the ‘worm dirt’ will pack an extra punch. Don’t go too overboard on the coffee grounds or you’ll throw out the green to brown ratio.
If you have a Spring garden project on the go collect some used coffee grounds when you grab your caffeine fix at your local Coffee Culture. If you have photos of your coffee boosted gardening results, I'd love to see them. Simply flick me an email with your photos of your garden having the caffeine treatment and I’ll see if I can arrange some caffeine for you too.
