What fertilizer should be used during the passion fruit fruiting period?

During the passion fruit fruiting period, which is the stage when the fruit develops and matures, it is very important to do a good job of fertilizing, which will directly affect the quantity and quality of the fruit. So what kind of fertilizer is best for passion fruit during the fruiting period? Let’s learn more about it below.

1. Fertilizer before flowering

Apply pre-flowering fertilizer half a month before flowering or after putting the plants on the trellis. You can apply high-phosphorus and high-potassium compound fertilizer to improve the quality of flowers, thus ensuring the quality and quantity of flowering of the plants.

2. Fertilizer after flowering

After the passion fruit blooms, if the number of flowers is small, no fertilizer is required; but if the number of flowers is large and the plant is growing well, you can consider applying some fertilizer after the flowers fade. At this time, topdressing is mainly based on phosphorus and potassium fertilizers, and the leaves are sprayed with boron source library + cytokinin + sea elf foliar fertilizer .

3. Fruit weight gain period

Passion fruit generally has two fruit weight increase periods, with a long time span, from the 20th day after flowering to the 48th day after flowering. At this time, high-potassium fertilizer should be applied to promote the formation of intrinsic quality. At the same time, calcium-magnesium sugar alcohol chelated foliar fertilizer should be sprayed on the leaves. The effect will be better if calcium and magnesium are supplemented together, especially for reducing wrinkled skin and preventing wrinkled and cracked fruits.

4. Coloring period

Spray 800 times the amount of Hongku solution on the leaves to help sweeten and color the fruit, increase yield and improve quality.

5. Fruit maturity

Mainly apply foliar fertilizer and control nitrogen moderately. You can spray the leaves with zero-nitrogen, full-nutrient phosphorus and potassium foliar fertilizer to improve the quality of the fruit inside and outside.

6. Fertilizer after fruiting

(1) Fertilization time: After the passion fruit is picked, supplement nutrients in time.

(2) Fertilizer selection: Mainly nitrogen fertilizer to promote rapid recovery of the plant and the growth of the next round of fruit.

(3) Fertilization method: Use the same soil fertilization method, spread the fertilizer evenly on the soil, and water it sufficiently.

In general, the key points of fertilization during the passion fruit fruiting period need to be determined based on the growth conditions and nutritional needs of the plant. Generally speaking, phosphorus and potassium fertilizers should be used as the main fertilizers, and trace elements and foliar fertilizers should be supplemented in time to promote the healthy growth of fruits and improve fruit quality.
