Is it good to put coffee grounds on your lawn?
Benefits of Using Coffee Grounds as Fertilizer This nutrient can help improve soil structure when composted or lightly worked into the soil. Nitrogen also helps plants with photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to create energy. Adding coffee grounds directly to the soil as a fertiliser can be a good option. Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser.To use coffee grounds as a fertiliser sprinkle them thinly onto your soil, or add them to your compost heap. Despite their colour, for the purposes of composting they’re a ‘green’, or nitrogen-rich organic material.Spread your used coffee grounds in a thin, even layer on a baking sheet lined with newspaper or paper towels. Place the baking sheet in a sunny spot outdoors or on a windowsill that gets plenty of direct sunlight.Coffee grounds can most certainly be added to your compost and also directly to your soil. Instead of simply tossing them out though, you may wish to incorporate them a bit more thoroughly by digging them in.
How often should I use coffee grounds as fertilizer?
Do not sprinkle more than a thin layer around your plants, or the coffee grounds can become impenetrable, preventing water from getting into the soil. If you evenly sprinkle coffee grounds around the plants once a week or so, the amount will likely be okay. Do not sprinkle more than a thin layer around your plants, or the coffee grounds can become impenetrable, preventing water from getting into the soil. If you evenly sprinkle coffee grounds around the plants once a week or so, the amount will likely be okay.Use them as a general fertiliser Mix your coffee grounds in with your mulch or potting soil to add growth promoting enzymes and minerals. Tip: Don’t use coffee on its own. It tends to clump together and creates a drainage barrier.With coffee ground fertilizer, a small amount once a week is beneficial, but for larger quantities, try to do so sparingly, such as once a month.Add coffee grounds to your compost, or spread dry coffee grounds directly on your lawn or garden each month to slowly nourish plants and improve soil quality. Acid-loving plants, such as azaleas and blueberries, thrive with coffee grounds, but they may harm other plants.Coffee grounds are neutral to slightly acidic (pH can range from about 6. H. Acidic-loving plants such as azaleas, blueberries, hydrangeas, rhododendrons, and roses will benefit from a sprinkling of coffee grounds around the base of plants.
When should you not use coffee grounds in the garden?
Coffee grounds contain caffeine, which can be harmful to some plants. Caffeine acts as a natural pesticide, which can inhibit growth, particularly for seedlings and young plants. This is especially true for plants that are sensitive to caffeine and tolerate acidic soil poorly. Plants that prefer alkaline soil, like lavender and lilacs, can be harmed by the acidity of coffee grounds. Plants that are sensitive to caffeine, such as geraniums and some herbs, can also be affected by the presence of coffee grounds.The plants that like coffee grounds include roses, blueberries, azaleas, carrots, radishes, rhododendrons, hydrangeas, cabbage, lilies, and hollies. You’ll want to avoid using coffee grounds on plants like tomatoes, clovers, and alfalfa.In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass.Myths about acidity After brewing, they’re close to neutral — around pH 6. Any pH change in the soil is temporary, Brewer said. That means coffee grounds won’t lower soil pH enough to benefit acid-loving plants such as rhododendrons, azaleas, blueberries, gardenias and blue-flowering hydrangeas.Slugs, snails, and other bugs are said to hate caffeine. Use coffee grounds for an all-natural and double-use ingredient. Lightly sprinkle the grounds over your soil and around the plants to deter smaller bugs and animals while enriching your soil with organic compost.
Which plants do not like coffee grounds?

You’ll want to avoid using coffee grounds on plants like tomatoes, clovers, and alfalfa. Are Coffee Grounds Good for Plants? Coffee grounds contain several key nutrients needed by plants, including nitrogen, potassium, magnesium, calcium, and other trace minerals. These are all nutrients that plants need to grow. The grounds are particularly rich in nitrogen, making them a great addition to compost.However, there are some plants that you should avoid using coffee grounds on. Plants that prefer alkaline soil, like lavender and lilacs, can be harmed by the acidity of coffee grounds. Plants that are sensitive to caffeine, such as geraniums and some herbs, can also be affected by the presence of coffee grounds.Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants. Mold: Wet coffee grounds can attract mold, which can be harmful to plants. Caffeine: While caffeine is not toxic to plants in small quantities, it can be harmful if used in large amounts.COFFEE GROUNDS FOR INDOOR PLANTS Houseplants can also benefit from the use of coffee grounds, though some may benefit more than others. Houseplants that prefer acid soil will be more receptive to coffee ground use. These include African violet, croton, gloxinia, monstera, peperomia, and philodendron.Worried that too much used coffee grounds might affect the pH of your soil? Like with any organic waste product you add to your compost, be mindful of ratios. Provided used coffee grounds are composted and make up less than 20% of total compost volume, they will not lower the pH of your soil making it acidic.
What are the disadvantages of coffee grounds as fertilizer?
Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants. Mold: Wet coffee grounds can attract mold, which can be harmful to plants. Caffeine: While caffeine is not toxic to plants in small quantities, it can be harmful if used in large amounts. Since the coffee grounds contain caffeine, they can inhibit the growth of the plants they are around. Just as coffee grounds are recommended as fertilizer, they are also recommended to control weeds.Use in fertilizer coffee grounds are much too acidic to add directly to soil as a fertilizer. But, coffee grounds contain potassium, magnesium, and are super high in nitrogen. By mixing coffee grounds with lime and organic matter in a compost pile, you get a shot of nutrients while cutting coffee’s natural acidity.Since the coffee grounds contain caffeine, they can inhibit the growth of the plants they are around. Just as coffee grounds are recommended as fertilizer, they are also recommended to control weeds.
What to mix with coffee grounds for fertilizer?
Don’t sprinkle too many dried coffee grounds; otherwise, they will block water absorption and airflow by making a thick layer over the soil. Apply as mulch on top of the soil: Combine used coffee grounds with shredded dry leaves, straw, tree bark, and grass clippings. Coffee Grounds as a Mulch If you’re trying to use them as a soil conditioner and haven’t had a chance to compost them, mix some coffee grounds with some well-rotted compost or manure and then add them to your soil as a mulch, but don’t forget that 20% ratio mentioned above.Sprinkle coffee grounds into mulch or on the lawn, then water them in. They’re also great for indoor plants; sprinkle a thin layer on top of the soil or mix them with potting soil during repotting.
