Using Coffee Grounds For Growing Vegetables
Is it beneficial to use coffee grounds as side dressing for growing vegetables (tomatoes, peppers, cucumbers, potatoes, lettuces, etc.) in my back yard? Some of the websites I've read say YES and some say to compost the coffee grounds first. Just trying to get an answer I can trust! Thank you.
Coffee grounds are a nitrogen source but are best composted with a carbon source in a compost pile. The grounds need to break down before they are truly a benefit to plants.
