How to fertilize potted orchids? There are three main fertilization methods for potted orchid plants, which are root irrigation, foliar spraying and plant material adding base fertilizer, in addition to understanding these three fertilization methods, breeders should also pay attention to some matters needing attention in fertilization. for example, fertilization concentration, fertilization time, fertilization times, etc., the specific editor will explain in detail below.

1. Fertilization methods of potted orchids

1. Root irrigation

Root irrigation means that the fertilizer is dissolved in water, and then the solution is watered in the plant material to be absorbed by Langen.

2. Foliar spray

Foliar spray is to spray the fertilizer liquid on both sides of the leaf to allow the leaf to absorb.

3. Adding base fertilizer to plant materials

Plant material to add base fertilizer is to put organic fertilizer particles or slow-release chemical fertilizer in the plant material, and then through the usual watering, let organic fertilizer particles or slow-release chemical fertilizer slowly dissolve, let Langen absorb.

II. Matters needing attention in foliar fertilization

1. Choose suitable foliar fertilizer.

The foliar fertilizers commonly used for foliar spraying are Huabao, blue fungus king, multi-wood, urea, potassium dihydrogen phosphate, calcium superphosphate, potassium sulfate and micro-fertilizer, which can be selected according to the specific conditions.

2. the spraying time should be suitable.

Foliar fertilization is applied in the evening when there is a breeze.

3. The concentration and method of spraying should be appropriate.

Foliar fertilizer is diluted to 3000-5000 times liquid, foliar fertilization requires fine droplets and uniform spraying.

4. The times of foliar fertilization should be strictly controlled.

Foliar fertilizer is generally not applied in winter, and the period of foliar fertilization is 10-15 days. When spraying foliar fertilizer containing plant growth regulators, the interval should be at least 7 days, in order to prevent harm caused by improper regulation. The concentration of fertilizer should not be too high to prevent fertilizer damage.
