Which NPK is best for coffee?
NPK 16:2:31 – Coffee Fertilizer | EzyAgric. Coffee grounds are a popular addition to composting material, and they can have several beneficial effects when added to compost piles. Coffee grounds are considered green materials, as they are rich in nitrogen, an essential nutrient for plant growth.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.To ensure that your coffee plant grows healthily and produces beautiful leaves, flowers, and fruits, we recommend using a complete fertiliser, i.Phosphorus (P) Weathered soils with low availability of phosphorous and high levels of iron and aluminum that induce P precipitation make it necessary to apply high amount of P fertilizers to ensure proper productivity of coffee. P increases plant’s height, stem diameter, root and leaf development and yield.
How to apply NPK on coffee?
Spread fertiliser evenly on the soil around the drip line (the outside edge of the canopy) of the coffee tree, as this is where most feeder/hair roots are found (figure 25). Keep fertiliser at least 100 mm from the stem of the plant; fertiliser applied closer than this can damage the coffee tree. coffee plant fertilizer feed the plant monthly during the growing season (spring and summer) with a balanced, water-soluble fertilizer. Reduce feeding during the fall and winter months.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.In my mind, that makes late winter/early Spring the best time to use coffee grounds as fertilizer for Spring blooming plants. Their buds were set long before, so adding nitrogen at that point will feed the plants without interfering with flowering.Though it is tempting to pour what’s left in your daily cup of coffee into your plants, it is best to only do this once a week to every ten days. That applies to both houseplants and outdoor plants.

Keep fertiliser at least 100 mm from the stem of the plant; fertiliser applied closer than this can damage the coffee tree. Coffee trees need a lot of potash, nitrogen and a little of phosphoric acid. Spread the fertilizer in a ring around each coffee plant and be careful not to put any on its trunk, branches or leaves. MANURE could also be added depending on organic matter of the soil.Coffee grounds are fine and dense. When wet, they clump together and form a barrier that restricts water and air. Plants that like well-drained, dry soil—such as succulents, herbs like oregano and sage, and many bulbs—don’t respond well to this change in soil texture.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.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.
Is coffee a good fertilizer for all plants?
Some plants don’t like coffee grounds, but many of them love it in their soil. Use coffee grounds for plants that thrive in slightly acidic soil as they lower the overall pH. Acidic-loving plants such as azaleas, blueberries, hydrangeas, rhododendrons, and roses will benefit from a sprinkling of coffee grounds around the base of plants.There are a select few plants that can benefit from fresh grounds—including acidity-loving Hydrangeas, Rhododendrons, Gardenias, Azaleas, Lily of the Valley, blueberries, carrots, and radishes—but generally, most common houseplants will prefer low to no acidity.
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. Plants That are Sensitive to Caffeine Roses: Caffeine can hinder their growth and development. Lilies: Caffeine can prevent their growth and may even cause their death. Hydrangeas: Caffeine can negatively impact their growth and soil acidity.
