Today Hua'er will introduce 3 kinds to everyone, use them to grow flowers with lush branches and leaves and exploding blooms, it would really be a pity not to use them.
1. Watermelon rind
Summer is the season when everyone eats watermelon, and watermelon rind is a very good "flower fertilizer". Use it to grow flowers, and it can make the plants grow more vigorously and bloom continuously.
Specific method: remove the red flesh and the outer skin, then cut into small pieces, or directly chop into bits, then put into a container, you can directly add clean water or rice washing water (fermentation is slower), control the ratio at about 1:100, you can drip in some insecticide to speed up fermentation, then seal it, put it under the sun to bake, and fermentation is complete in about a month.
After fermentation is complete, filter out the residue, then dilute 20 times, and it can be directly poured onto potted plants.
2. Earthworm castings
Earthworm castings can be said to be the king of organic fertilizer, containing a great many nutrients, can be directly absorbed by plants, the fertilizer effect is very long-lasting, and it will not cause any harm, and earthworm castings have strong water retention and drainage.
In summer, in parks and on roads you can see some earthworm castings, you can collect some, then put them under the sun to bake for a day, crush them into powder, and you can directly sprinkle them on the surface of the potting soil or dig a few holes and bury some in. When watering, the powder will penetrate into the soil and be absorbed by the root system, making the plants grow rapidly and the flowers bloom large and vivid.
3. Crayfish shells
Many people especially like to eat crayfish, and those leftover shrimp shells are a very good "flower fertilizer", containing rich calcium, magnesium, phosphorus and other elements, all of which are necessary for plant growth.
To collect crayfish shells, clean off all the meat and other debris, then rinse with boiling water 2-3 times, then soak in clean water for 1 day, crush them and spread them out under the sun to bake for 2-3 days. When potting or repotting potted plants, then pour in some crushed crayfish shells as base fertilizer, increasing the air permeability of the soil and providing nutrients to the plants.
