Rich in potassium, coffee grounds act as a natural fertiliser, boost plant health and help repel pests like slugs.

Not only do they improve soil quality and attract earthworms, but they can also be used indoors to freshen up your home.

With so many benefits, it’s clear that coffee grounds are a versatile household and gardening essential, and the Facebook account David Attenborough Fan is among many enthusiasts raising awareness of its many uses on social media.

They advised: “Throwing away coffee grounds is one of the worst things you can do they're an invaluable resource for both home and garden.

“Discarding coffee grounds is a mistake, as they have multiple practical uses. Rich in potassium, they act as a natural fertiliser, enhance plant resistance, and are excellent for composting.

“Additionally, they attract earthworms, improve soil health, and help repel pests like slugs and moles.”

But it’s not just gardening needs that coffee grounds can fulfil, as according to the social media user, they can also be used indoors for a variety of purposes.

They said: “In the home, coffee grounds effectively absorb odours, making them useful for freshening the refrigerator and other areas.

“When mixed with essential oils, they also provide a pleasant aroma. Furthermore, they can cover scratches on furniture, naturally darken hair, soften hands, and help maintain the colour of dark clothes in the wash.

“One-line summary: Coffee grounds are a versatile household and gardening essential, serving as a natural fertiliser, pest repellent, and deodoriser.”

The post seems to get a good reception from other gardening fans, who started sharing a list of other uses for coffee grounds.

Becky Harsh said she uses them to keep cats out of her garden, as they “apparently don't like the smell. It worked.”

Kristine Byrne added: “I've used my coffee grounds for over 20 years on all my MANY house plants. No other fertiliser. They all thrive.”

For those who don’t drink coffee who are wondering where to find grounds, Facebook user Julie Reifenrath recommended asking coffee chain Starbucks for theirs as they “will gladly give you bags of grounds.”

Ellen Hanses further suggested: “Two things: use the kind of pods you fill and empty and you can save coffee grounds in a cooler or your freezer til ready to put in compost.”
