COFFEE grounds don’t belong in the trash, they belong in your garden.
Packed with nutrients like nitrogen, potassium, and magnesium, they can work wonders for vegetables, turf, and landscape plants.

In Florida’s Space Coast, where hot weather lingers through September, experts say the morning and evening hours are best for yard work.
Used grounds benefit many plants, from vegetables to acid-loving species and even some houseplants.
In Brevard County, Florida, gardeners are discovering coffee grounds as a simple way to boost soil health while reducing waste.
Acid-loving plants thrive with a touch of coffee.
Blueberries, azaleas, rhododendrons, hydrangeas, camellias, gardenias, and roses all respond well.
Veggies and fruits also enjoy the nitrogen boost from grounds.
Carrots, radishes, potatoes, strawberries, and leafy greens like kale and spinach can flourish.
Even some houseplants like African violets, peace lilies, pothos, Christmas cactus, and philodendrons benefit.
But not all plants like coffee.
Geraniums and asparagus ferns do poorly with it, though ferns being invasive, gardeners may still spread grounds around them.
Compost or charged biochar can also be scattered in the yard to enrich soil.
September is also the last call for poinsettia pruning this year.
Herbs to plant this month include chives, fennel, garlic chives, sage, sweet marjoram, thyme, mint, oregano, and rosemary.
Vegetables ready for planting in September include arugula, beans, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celery, Chinese cabbage, collards, cucumbers, eggplant, endive, kale, lettuce, mustard, onions, peppers, radish, spinach, squash, Swiss chard, tomatoes, and turnips.
