Coffee invigorates not only people, but also plants! If you are an avid coffee lover, do not rush to throw out the sleeping thick. Make it "work" on your crop with the help of our advice.
Many of us do not think our morning without a cup of aromatic strong coffee. This black drink has a truly "magic" effect on the body: thoughts become clear, increases efficiency and mood. Did you know that in the same way coffee can affect plants? Of course, with proper use!
1. Coffee as fertilizer
Naturally, the effectiveness of coffee can not be compared with any high-speed fertilizer, and even more so it does not replace the complex feeding. But it is necessary to recognize that the introduction of sleeping coffee grounds into the soil around the plants has a beneficial effect on them.
Decaying organic matter increases the biological activity of the soil. First, it saturates the soil with nitrogen. Secondly, it attracts earthworms, which loosen the soil. Third, coffee, used as a fertilizer, allows plants to more easily absorb copper, magnesium, potassium, and phosphorus from the soil.
Despite the fact that coffee contains 2% nitrogen, this does not mean that it can replace high-grade nitrogen fertilizer. As the coffee grounds decompose for a rather long time, the elements are released slowly.
There is an opinion that coffee significantly increases the acidity of the soil, therefore it is suitable as a fertilizer only for plants that require low pH levels (conifers, rhododendrons, heathers, etc.). However, this is not quite true. Coffee really "sour", but only fresh.
Sleeping coffee grounds has a neutral reaction - around pH 6.5-6.8 (with an ideal acid-base balance of pH 7). For fidelity, before using in the garden it is desirable to wash the thick with clean water.
2. Compost from coffee grounds
Composting used coffee is nowhere easier - simply throwing the thick into the compost pile. Again, given the controversy about its acidity, for greater peace of mind, it is advisable to pre-rinse it under running water.
Behind the thick, you can send and paper coffee filters. All this perepet and will benefit the plants.
The only important nuance that should be taken into account when composting - competent selection of components of the compost. In addition to coffee grounds and other food waste, more “solid" components must be added to the compost pit: straw, wood residues, manure, mowed grass, etc. Coffee grounds should be no more than 15-20% of the total compost, otherwise it simply will not grind.

3. Mulch from coffee grounds
Many gardeners use coffee grounds as environmentally friendly mulch. It is safe for plants, it releases nutrients in the soil, enriches it with nitrogen, attracts earthworms, looks natural and pleasing to the eyes.
However, the main disadvantage of such mulch - it can begin to mold. To avoid this, again, we advise you to wash the thicket with clean water and dry it before spreading it over the soil surface.
In addition, if you drink coffee with sugar and milk, of course, they remain on the coffee grounds. Sweet mulch can attract ants and other insects. Therefore, it is necessary to rinse the mass before drying.
4. Soil improver
If the quality of the soil on your site leaves much to be desired (it is too light, or, conversely, not enough air and moisture permeable), its structure needs to be improved. Good soil "breathes" easily passes air and moisture. To achieve this effect, you can add coffee grounds to the top layer of soil.
5. Growing greens in coffee
As an interesting experiment, you can try to grow greens in a container filled with coffee substrate. Such a project called Urb was proposed by London industrial designer Blake Parkinson.
The main thing is to periodically feed the seedlings with complex fertilizers in order to prevent a shortage of nutrients.

6. Pest Barrier
It is believed that the coffee grounds scattered around the plants, serves as a reliable barrier against slugs and snails, which are a real scourge of some crops.
In addition, according to some gardeners, coffee can not only scare away, but also destroy the larvae of insect pests, including mosquitoes and bedbugs.
Of course, in the fight against insects dangerous for the crop, it’s not worth relying solely on coffee, but attracting it to your side as an additional ally will not hurt.
7. Cat repeller
If you are outraged by the fact that cats use your beds as a toilet, generously “pick up” the garden of coffee grounds. A strong coffee smell will discourage any desire to relieve the need in this place from the tailed pranksters.
