1、 What fertilizer does orchid use

Inorganic fertilizer: inorganic fertilizer, i.e. chemical fertilizer, can be applied appropriately at the orchid growth stage. Chemical fertilizer is mainly nitrogen fertilizer and potassium fertilizer. Urea and potassium dihydrogen phosphate can be applied. The urea solution can be diluted 150-200 times with water to irrigate the roots of orchids, and the potassium dihydrogen phosphate can be diluted 200 times with water to spray leaves

Organic fertilizer: during the growth period of orchids, organic fertilizer is mainly applied, such as cake fertilizer, fish bones, orange stalks, fallen leaves, grass, human and animal manure, which can also supplement sufficient nutrients to orchids, and the fertilizer effect is relatively mild. Organic fertilizer is mainly used as base fertilizer. When it is used, it should be sterilized, insecticidal and fully fermented. When it is put into the basin, it should be mixed into the soil to ensure good nutrient supply. It can also be used as topdressing. You can dig pits in the soil around the roots of orchids and apply fertilizer inside to cover the soil

Water soluble fertilizer: orchid can also be applied with water-soluble fertilizer, mixed with water, and then watered to the root of orchid. Water soluble fertilizer can promote the root to fully absorb nutrients

Special fertilizer: when raising orchids, special slow-release fertilizer for orchids can be used. It is specially developed for orchids and can effectively promote the growth of orchid roots

2、 Precautions for orchid fertilization

Sterilization and disinfection: when using organic fertilizer, orchids can be sterilized and disinfected in advance. They need to be fermented first and then boiled at high temperature to kill bacteria and insect eggs

Thin fertilizer and frequent application: when applying fertilizer to orchids, we must adhere to thin fertilizer and frequent application
