With much talk in the news about the impact we’re having on the planet, no doubt there are many homeowners out there keen to do as much as they can to reduce the amount that’s sent to landfill… and no step is too little in this regard.
If you’re a big coffee addict, make sure you don’t chuck your coffee grounds away as these can be used to help fertilise your garden and keep your plants growing big and healthy. Just ask your North London gardening service – they’ll tell you just how good coffee can be for plant growth! Don’t bin your filters either, as these can be used in compost as well.
It couldn’t be easier to do – simply put your coffee grounds right on top of the soil as a form of fertiliser. Do remember, however, that while your old grounds can add nitrogen to your compost, they won’t add it immediately to the soil.
You’ll likely find that water retention, drainage and aeration is improved by using coffee grounds in this way. If you’re new to this, perhaps consider rinsing your coffee grounds first as fresh ones are quite acidic. Once done, work the grounds into the soil around the plants – and you can even use leftover diluted coffee in a similar way as well.
For your indoor plants, take particular care. If you’re not an experienced gardener, it might be worth leaving the grounds for plants outside. As the coffee grounds decompose, fungi will grow and this can attack and even potentially kill your plants. Your soil may also be kept too moist if you put a thick layer of grounds on top and this can damage the roots of your plants.
Plants that like acidic soil
Because coffee grounds create more acidic soil, do some research to find out which plants would benefit the most from this kind of fertiliser.
According to Gardeners’ World, the top ten plants that thrive in acidic soils are magnolias, lilyturf, Japanese anemones, Trillium erectum, ceanothus, Calluna vulgaris, Piieris japonica, bilberries and camellias.
If your garden (indoor or out) doesn’t support the use of coffee grounds, you can still recycle these in other ways if you’re really keen for them not to end up in landfill.
For example, you can put them in a small open tin or container and keep it in the back of the fridge to help absorb bad food odours. They’re also a natural abrasive and can be used on an old cleaning cloth to scrub away stubborn dirt on your worktops or dishes.
Or what about a fun project over the Christmas holidays, using your old coffee grounds to make homemade candles? You’ll need some candle wicks, some wax, some old mugs, a saucepan and a funnel to get the job done. You could even add essential oils to create a few different smells… a good festive project that could double up as a gift for someone as well!
