Fertilizers such as potassium dihydrogen phosphate, bean cake fertilizer, fruit ferment, rotten leaf fertilizer, nitrogen, phosphorus and potassium fertilizer, flower fertilizer special for orchids, compound granular fertilizer and the like can be applied to promote the orchids to bloom more.Fertilization needs to abide by the principle of "thin fertilizer and frequent application" to avoid fertilizer damage.The best time to fertilize is in the evening, the next morning water once, every 2-3 weeks to apply fertilizer.In addition, after flowering, nutrients need to be supplemented in time to make the plant survive the winter smoothly, resist spring cold and not hinder the normal growth of the plant in the next year.High temperature in summer and slow growth in winter can reduce the ability of root to absorb nutrients, so fertilizer can not be used to avoid fertilizer damage to roots.
1. Homemade nitrogen fertilizer: You can use vegetable leaves, peanuts or expired milk powder, grind it into powder and put it into a clean and transparent container.Then add more than half of the clean water to the container and seal the opening.Then put it in a well-lit place, wait until the surface solution in the container turns black, and then use it to water orchids.However, before use, it needs to be diluted with clean water, and the concentration should not exceed 5%.
2. Self-made phosphate fertilizer: fish bones, pork bones, egg skin and other things together into the container, then pour water and starter, and then seal the container.After the material in the container is fully decomposed and fermented, the upper solution is taken out and diluted with water, which can be used to irrigate orchids.
3. Self-made potash fertilizer: You can use the rest of the tea, in which the addition of starter, such as its full fermentation after decomposition, water can be used.It can also be applied to orchids by adding water to plant ash.
