How often should ginger be fertilized?

Ginger is generally fertilized in July and August, usually in combination with watering, with an interval of about 10-20 days between each application. When the side branches of the plant are the same length as the main trunk, the demand for fertilizer is the greatest, and then it can be fertilized again after the beginning of autumn.

What fertilizer to use for ginger

1. Base fertilizer : It is recommended to apply 5,000 kg of organic fertilizer and 60 kg of compound fertilizer per mu of ginger. The organic fertilizer must be decomposed before use. You can also apply high-quality decomposed chicken manure.

2. Topdressing : In the seedling stage of ginger, it is necessary to apply fertilizer for seedling growth, apply compound fertilizer with water, and also apply ammonium sulfate or diammonium phosphate solution. In the flowering period of the plant, it is necessary to apply fertilizer mainly composed of organic fertilizer.

Ginger fertilization method

1. The growth rate of ginger is very small, and the first topdressing is needed during the seedling stage. The fertilizer is mainly seedling-strengthening fertilizer, and about 20 kilograms of ammonium sulfate is applied per mu.

2. When ginger enters the swelling period, you can use ginger fertilizer once according to the growth of the plant, mainly high-potassium water-soluble fertilizer, which can be directly sprinkled on the surface of the soil.
