How do the plants in the coffee shop fertilize the coffee grounds and grow flowers?

Coffee grounds contain a lot of nitrogen, which is very suitable for plants that like acidic soil, so when using coffee grounds as fertilizer, it is important to note that not all plants are suitable to use coffee grounds as fertilizer. Only by making fertilizer for flowers that like acidic soil, we can get twice the result with half the effort.

How to convert coffee grounds into horticultural compost is a very important link. It must be ripe before it can be used as fertilizer, otherwise it will not only fail to achieve fertilizer effect, but also burn roots. Coffee also belongs to agricultural products, although it goes through the process of baking and so on. But the basic quality remains the same, and it is also suitable for composting.

Composting case 1:

Dry composting: put the coffee grounds on the balcony, stir it every day, and put it into the pot after about 10 days. Wet composting: put the coffee grounds on the balcony without stirring it to become moldy. A few days later, it is found to be full of mold, and then mixed with sand and put into the pot. Composting case 2:

Put the coffee grounds in a fertilizer bag, which is breathable, not necessarily a fertilizer bag, and put it in a place where the sun will not shine directly. The principle of complete fermentation of compost is that it can reach 60 ℃, and it is difficult to reach the high temperature period if there is too little coffee grounds, so I put it in a fertilizer bag to keep warm. After two or three days, because of the high amount of carbohydrates in the coffee grounds, the heat will begin to break down first. Wait until 3-4 days after the fever, because I keep adding new slag every day, I have to turn the pile so that the unheated slag turns to the middle and has a chance to get hot. It is best to ferment until there is no original coffee flavor, or even a mildew smell from actinomycetes, which means that it has entered the post-ripening stage of composting and can be used and will not burn roots. But it still depends on what kind of plant you use. Some grass flowers are relatively young and prone to fertilizer damage, so wait a few more days for them to ripen. Generally, it is better to turn the pile, the fever period is about 21 days, and the post-ripening period does not need to turn the pile, but it takes about 40 days.

Note: we should measure the size of the flower organ and use coffee grounds appropriately, but do not think that coffee grounds are fertilizer and put coffee grounds into the soil.
