Flower fertilizer does not need to be applied every day, but it should be applied regularly. In fact, it can be applied occasionally according to the laws of family life. If you have time to plant flowers, it is best to spray the leaves every day, in the morning and evening, and not at noon; The most important thing is to plant flowers on the balcony. The balcony is generally sunny, and the water in the flowerpot is quickly lost. I water it once a day in summer and once every two or three days in winter. According to the humidity of the soil, it is best to water the soil completely. However, it should be noted that according to the habits of green plants, some plants that like to dry (such as cactus) should not be watered too often.

Use rice washing water as fertilizer.

Taomi is the most common waste in the kitchen, almost every day. There are a lot of fertilizers for rice washing water on the internet, and there is no technical content. The general principle is to ferment them before use. Some netizens said that you can't water the flowers directly with freshly washed rice, which will kill people. Actually, this is really not that serious, because I used to be like this all the time. I watered the rice washing water that day, but the flowers didn't die, but the effect was not good. Production method: put rice washing water into a container for fermentation. Put the rice washing water into a container, which can be a large mineral water bottle or a bucket. If it is indoors, it is best to use a sealed one. It is best to put it outdoors in the sun and generally seal it for more than a week. Sometimes I am lazy, just put a bucket on the balcony and let the rice washing water stand for more than 10 days to ferment. It's not sealed. In fact, if the bucket doesn't move, it won't smell. Water the flowers after dilution. After the fermented rice washing water is diluted according to the ratio of "rice washing water 1: 5 clear water", it can be used to water flowers normally. Try to pay attention to the roots when watering, and don't dirty the leaves.

Use coffee grounds as fertilizer.

For people who drink coffee every day, coffee grounds are the most. In a word, coffee grounds are the simplest fertilizer and a good raw material for making flower fertilizer. Production method: drying coffee grounds. I spread my coffee in the sun and exposed it in the open air for a while; Mixing coffee grounds with soil, adding water to keep it moist, uniformly stirring, and packaging in a sealed bag; Put the bag in the corner for fermentation for about 3 months, preferably in the sun, and then it can be used for fertilization. In fact, my method is to directly replace one third of the soil in the flowerpot.

Use egg shells as fertilizer.

Egg shell is also a common waste in every kitchen, and it is rich in nutrition and a rare good fertilizer for flowers and plants. Before talking about the method, Shuaimeng Pig has a little reminder: Because eggshells are very nutritious, the dosage should not be too large, and it is recommended not to exceed 15% of the total nutrient soil. Too much will affect absorption and even cause the opposite result. Production method: cleaning. Clean the used egg shell, pay attention to remove the egg white, and expose it to the sun for more than a week; Mash. Mashing dried egg shells can be handled by a cooking machine, which saves trouble. After mashing, pour a little white vinegar into the eggshell powder, then stir it to ensure that the eggshell is wet with vinegar, and then put it into a sealed bag (a thicker fresh-keeping bag is enough), so as to ensure the tightness of the bag.

Exposure. Put the bag in the sun for 2-3 weeks again. After cleaning, you can see that it has decomposed and softened, and then you can take it out and dry it again to fertilize the flowers and plants.
