Using coffee grounds for gardening really helps! Know all about the correct ways to use coffee grounds in the garden by reading this educative article.
The next time you finish your morning coffee, think twice before dumping the grounds. Coffee grounds can do wonders in your garden, not necessarily in the ways you would expect. Although they do not provide abundant nitrogen and do not lower soil pH much; they can enrich your garden soil and compost pile. Plus, they do not contain any harsh chemicals.
Coffee Grounds as Fertilizer
Coffee grounds contain 2% of nitrogen, but plants can not use this until it breaks down. As these grounds decompose, the low nitrogen level in them acts as a long-acting fertilizer.
Coffee grounds also provide a healthy and slight dose of other basic nutrients like phosphorus and potassium. They also contain small quantity calcium, manganese, zinc, and iron. You can sprinkle coffee grounds directly onto the soil or
Coffee Grounds in Soil
Coffee grounds have long been bragged to lower the soil pH, but unlike popular belief, most of the acidic content gets depleted during brewing. Laboratory analysis shows that they are slightly acidic to neutral and make a minor to no impact on the soil pH.
But who cares about the acidity, coffee grounds improve soil structure directly and in no time. Poor Soil, low in organic matter benefits greatly when amended coffee grounds.
By adding organic matter to the soil, they improve drainage, water retention, and aeration of the soil. Coffee grounds in the soil also improve the seed germination and growth of the plant. What is more advantageous is that they prevent soil-borne diseases like wilts, fungal rots, and some bacterial pathogens.
Coffee Grounds as Compost
If you’re about to add coffee grounds to your compost piles, restrict it to the range of 20 to 25 percent only. Higher levels than this can suppress beneficial microorganisms, so don’t overdo it. Balance your compost with other organic materials such as residue of grass clippings, dry leaves, woody prunings newspaper, or similar composting materials. You can also add it to worm bins as they love coffee grounds.
Coffee Grounds for Mulching
Coffee ground mulching is becoming popular because of the claims that they deter pets, obstruct weeds, and aerate the soil. But as coffee grounds have a fine texture, their use as mulch works best only in combination with coarse organic mulches. When used purely without mixing them with other organic matter, they can cause more harm than good. Instead of keeping the soil, moist, coffee grounds will dry out the soil more quickly. Some organic materials you can use with coffee grounds are dry leaves, compost, barks, and twigs. They enhance the mulch and negate the effect of using coffee grounds alone.
NOTE: In case of a shortage of coffee grounds, ask any nearby coffee store, and you might get them for free.

Coffee Ground as Pesticide
Many gardeners believe that slugs and snails tend to steer clear of the regions treated with coffee grounds. It’s due to the popular belief that coffee growing repels slugs and snails and other pests. Some believe that the abrasive texture of coffee grounds is something slugs can’t go through due to their soft-bodies. Although there is no proof of such claims, many gardeners still use coffee grounds as fertilizer. You can try it out and see if it works for yourself. Let us know in the comments section!
