What fertilizer is the best for orchids?

As the saying goes, each person has his own way of raising orchids. For the question of what fertilizer is best for orchids, Lanyou might as well read this article carefully. This article not only has the author's experience on the use of fertilizer in the process of raising orchids, but also adds other orchid friends' understanding of fertilizers.

Fertilizer, to put it simply, is nitrogen, phosphorus, potassium and trace elements. According to personal preferences and cultivation environment, the formula of plant material is also various, with different proportions of soft, hard, coarse and fine. What is discussed here is the formula of soft and hard 2:1, particle 1cm, peanut shell + pine bark (coconut shell) + river stone (gravel), this formula is more used in batch orchid cultivation. There are also 1:1, or soft materials such as whole bark, peanut shell, coconut shell or even stone. What these recipes have in common is light, which can be said to have no fertilizer effect. Therefore, the use of fertilizer is more controllable and the effect is intuitive.

At present, the main brands of orchid fertilizer are: long-acting fertilizer (slow-release fertilizer): Orchid, Haokangdo, magic fertilizer, Wolida, Prian, water fertilizer (water-soluble fertilizer): Huabao, Huaduo., as well as some nutrient fertilizers, such as seaweed essence and other organic fertilizers. The formula of long-acting fertilizer used in Lanjie is mainly high nitrogen type 16-8-12 (Ordovician green), average, 13-13-13, high phosphorus and potassium type. Water and fertilizer is (nitrogen-phosphorus-potassium) 20-20-20 10-30-20.

Long-acting fertilizer can provide quantitative nutrition for orchid growth for a long time, and water and fertilizer can properly regulate the growth process to supplement trace elements. I use long-acting fertilizer with average fertilizer, which is released at the beginning of spring and managed for a year to improve balanced nutrition. Water and fertilizer: when budding to 7-8 branches, use 20-20-20 formula, growth general fertilizer, balanced formula to promote plant growth, suitable for summer application, can be used for foliar spraying; 8-branch trees use 10-30-20 formula before budding to increase the corm, can effectively promote flower bud differentiation, buds strong and increase the number of flowers, the color is also more bright.

Lanyou's point of view: any practice of rich fertilizer, heavy water and few fertilizers is too biased, and it is a psychological obstacle that orchids dare not apply fertilizer. In the eight-character constitution of agriculture, "fertilizer" is the second word, which shows its position in the eight characters. Fertilizer must be used. The question is what fertilizer to use, when to use it, what kind of seedling situation and dosage, ways and methods of use, and so on. These are the things that should be discussed and studied.

Orchid friends point of view: proper fertilization can promote the growth of orchids. The plant is long and resistant to disease. It is not the result of the hormone Cui Miao. If you fertilize too much. It's easy to hurt the roots. On the contrary, it does not grow well.
