What kind of fertilizer is used to grow passion fruit?

Passion fruit grows vigorously and has a large amount of growth. It can be planted in the same year and can bear fruit in the same year, so the demand for fertilizer is relatively large. In particular, the current pressure of passion fruit virus disease and stem base rot has increased. Many orchards have changed to one type per year. If the fertilizer cannot keep up, the output cannot be guaranteed.

Passion fruit requires a large amount of nitrogen and potassium, followed by phosphorus, calcium, and magnesium. In addition, it also needs trace elements such as boron, zinc, iron, manganese, and molybdenum. At different periods, passion fruit has different nutrient requirements. For example, when the bud grows, the nitrogen consumption is large; the demand for phosphorus, boron, magnesium and other elements increases during the flowering period; potassium and calcium should be supplemented when the fruit is colored.

Passion fruit is a shallow-rooted plant. The topdressing is too close to the root system, excessive fertilization, too high concentration, and the application of immature organic fertilizers, etc., may cause fertilizer damage, especially during the seedling stage, where fertilizer damage occurs more frequently.
