1、 With what fat

Potassium dihydrogen phosphate, bean cake fertilizer, fruit enzyme, rotten leaf fertilizer, nitrogen, phosphorus and potassium fertilizer, special flower fertilizer for orchids, compound granular fertilizer and other fertilizers can be applied to promote more orchids to bloom. Fertilization should follow the principle of "thin fertilizer and frequent application" to avoid fertilizer damage. The best fertilization time is in the evening. Water once in the morning the next day and apply fertilizer every 2-3 weeks. In addition, nutrients need to be supplemented in time after flowering, so that the plant can survive the winter smoothly, resist spring cold and do not hinder the normal growth of the plant in the second year. High temperature in summer and slow growth in winter reduce the ability of roots to absorb nutrients. Fertilizer can not be used to avoid fertilizer damage to roots

2、 Method

1. Homemade nitrogen fertilizer: you can use vegetable leaves, peanuts or expired milk powder to grind it into powder and put it into a clean and transparent container. Then add more than half of the clean water into the container and seal the opening. Then put it in a place with sufficient light. After the surface solution in the container turns black, it can be used to water the orchids. However, before use, it needs to be diluted with clean water, and the concentration should not exceed 5%

2. Self made phosphate fertilizer: put fish bones, pig bones, egg skin and other things into the container, then pour water and starter, and then seal the container. When the material in the container is fully rotten and fermented, take out the upper solution and dilute it with water, which can be used to irrigate orchids

3. Self made potash fertilizer: you can use the remaining tea, add fermentation agent into it, and mix it with water after it is fully fermented and rotten. You can also mix plant ash with water to apply it to orchids
