The eight benefits of growing flowers with coffee grounds make it easy to get the greenest fertilizer

Coffee grounds can be used to grow flowers, which contains a lot of nitride, which is very suitable for plants that like acidic soil, so making fertilizer for flowers that like acidic soil can get twice the result with half the effort.

Coffee grounds must be ripe before they can be used as fertilizer, otherwise they will not only fail to achieve fertilizer efficiency, but also burn roots. Coffee also belongs to agricultural products, although it is roasted, but the basic quality remains the same, and it is also suitable for composting.

1. How to get coffee grounds?

Coffee grounds can be obtained in some coffee shops, or coffee grounds will be produced after self-bought coffee beans are ground and roasted. After brewing coffee with a coffee machine, there will be a lot of coffee grounds, coffee powder can be bought, and there will be a lot of dregs after cooking.

(of course, you can also ask the coffee shop owner directly, they are happy to give it to you, thinking that these are their useless waste.)

2. Improve plant nutrition.

Coffee grounds contain 2% nitrogen, but the plant cannot decompose it. If it is thrown directly into the soil, the natural decomposition is very slow, and the decomposition process generates heat and burns the plant's roots, so it is usually sealed and fermented and then mixed into the soil. This is beneficial and harmless.

Coffee grounds also provide other basic nutrients, such as phosphorus and potassium, as well as small amounts of magnesium and copper. Potassium, magnesium and copper can also make plants grow healthier. These are essential trace elements for plant growth.

3. Coffee grounds in the soil

The effect of coffee grounds is still good. It can reduce the ph value of the soil and make the soil slightly acidic. Laboratory analysis shows that coffee grounds are slightly acidic to neutral, which has a little effect on the soil ph value.

5. Promote seed germination.

Adding coffee grounds to the soil can also improve seed germination, make plants grow better and prevent plant pathogens from infection, such as wilting, fungal rot and the outbreak of some bacterial pathogens.

6. Coffee grounds compost

You can mix 20-25% coffee grounds into the compost, which takes a while to accumulate. If you put too much, it will inhibit the beneficial microorganisms, so don't put too much. Other composting materials can choose grass shavings, hay, fallen leaves, peel and kitchen waste.

Coffee grounds mixed with withered leaves and hay is an excellent compound fertilizer, but also can prevent the root system from attracting insects.

After fermentation, it is mixed with the soil, rather than poured directly into the flowerpot, because only after fermentation can it become a nutrient absorbed by flowers, and the heat generated during fermentation will burn the flowers to death.

Save the coffee grounds to a certain amount, mix them in the soil, pour some water on them, and cover them with plastic bags. It was completely fermented after a quarter.

7. The covering effect of coffee grounds

Coffee ground mulch has become popular because they prevent pests and pets from taking away and prevent claims for weeds and soil aeration.

Coffee grounds cover the soil to prevent slugs and snails from invading, keep your pets away from plants, prevent weeds and increase the air permeability of the soil.

Of course, just sprinkle a thin layer, if you put more, it is very easy to hurt plants, only need about 1 cm coffee grounds layer on it, and not very suitable for potted plants, more suitable for ground cultivation.

8. What plants like coffee grounds?

Fertilizer is applied to nitride-loving plants and most perennials and onions.

Scatter coffee grounds in the flowerpots of acidic plants cultivated at home, such as azaleas, roses, camellia, Milan, etc., can help produce more beautiful and brighter flowers.
