Got a coffee habit? I sure do. The day doesn't truly start until after the first cup and I generally revisit the coffee pot several times over the course of the work day. I'm at peace with it, and as the spent ...grounds pile up, they make a nice addition to the compost pile.
Coffee grounds are acidic, nitrogen-rich and have plenty of minerals like copper and magnesium and the compost heap is a fine option for putting coffee grounds to good use, but these days I'm finding other great uses for the by product of my favorite vice that may have it beat.
Once you've had your morning cup, before emptying that filter, check out these great ways to use coffee grounds that go beyond the compost bin.
The same qualities that make coffee such a good candidate for composting can also be put to use by adding directly to planting soil. The minerals help keep plants healthy and the acidity of coffee will give a boost to crops craving lower pH levels.
Last summer I spent some time experimenting with natural wood stains and one of my favorites was the warm, mellow hues coffee grounds bring to natural wood. You can use the leftover coffee from the pot or soak spent grounds for a couple of days to get rich tones ready to use on woodwork.
Boil coffee grounds in a large pot, remove from heat and submerge natural fabrics in the pot to get a beautiful beige or brown. The longer it soaks, the darker it will become.
The nitrogen in coffee grounds is a surprisingly effective ant repellent. Sprinkle grounds around doorways, windows or foundations to keep ants out of the house or use around the garden to create a natural barrier against invading ants.
Like tea leaves, rubbing coffee grounds on your hands will remove objectionable odors like garlic, onions or fish.
If any or all of these great uses for leftover coffee grounds spark your interest, but you don't indulge in Canada's favorite hot beverage, you're not out of luck. Check with your local barista. Many coffee shops save their grounds for gardeners looking for a soil boost and are happy to share the wealth.
