What is the best fertilizer for cabbage?

Cabbage fertilization time

Cabbage needs to be fertilized during its growth period. Generally, dilute fertilizer and water are applied at intervals of 15-20 days. When it enters the rosette stage, the demand for fertilizer and water is the greatest, and top dressing should be carried out.

What fertilizer to use for cabbage

Cabbage has a long growing period and requires a lot of nutrients. Note that it is important to apply nutritionally balanced compound fertilizer and sufficient nitrogen fertilizer, so its leaves will be large and dark green. Applying a certain amount of potassium fertilizer can promote its growth and development and increase yield.

Cabbage fertilization method

1. Fertilization during the seedling stage

Cabbage needs to be applied with fertilizers containing nitrogen, phosphorus and potassium during the seedling stage. When nitrogen is insufficient, the lower leaves will age and the color will be lighter. When phosphorus is insufficient, the color will be very dark and the leaves will unfold slowly. To ensure fertilizer supply in the early stage of seedling cultivation, 0.10% of compound fertilizer can be added. The amount used should not be too large to prevent seedling burning. The application of accelerated nitrogen fertilizer should be reduced before winter.

2. Application of basal fertilizer

Cabbage likes fertilizer. Before planting, sufficient base fertilizer needs to be applied. You can use rotted manure or compost, and add an appropriate amount of phosphorus fertilizer, which is beneficial for its early seedling growth.

3. Apply fertilizer as needed at the right time

After cabbage is planted, you can apply accelerated nitrogen fertilizer while watering, which is beneficial to the recovery of root growth. During the period from heading to harvest, the demand for nutrients is relatively large, so it is necessary to ensure sufficient supply of fertilizer and water. Two top dressings can be carried out from the end of seedling establishment to the end of rosette stage, and potassium fertilizer should be added before harvest.

Cabbage fertilization precautions

Cabbage fertilization needs to follow the principles of stabilizing phosphorus, controlling nitrogen, and increasing potassium. During its rosette stage to heading period, you can apply boron, calcium and other trace element fertilizers. After fertilizing, you can water it in time to avoid fertilizer damage.
