What fertilizer should be applied to star anise to produce more fruits?

Star anise, also known as star anise and aniseed, is a common seasoning spice. The star anise produced in Guangxi is of excellent quality and is famous for its plump fruit, rich aroma and mellow taste. So what kind of fertilizer should be applied to star anise to produce more fruits? Let’s take a look with the editor below.

1. What fertilizer should be applied to star anise to produce more fruits?

1. Spring fertilization

In March and April, spring shoots begin to sprout and young fruits grow rapidly. It is recommended to apply ammonium carbonate quick-acting fertilizer or urea + compound fertilizer , and spray potassium dihydrogen phosphate + boric acid on the leaves to promote spring shoot growth and reduce fruit drop.

2. Fertilize during flowering period

In June and July, star anise enters the flowering period, and flower fertilizer should be applied heavily. Urea + compound fertilizer or urea + potassium chloride should be applied in the furrows. At the same time, zinc sulfate + boric acid + potassium dihydrogen phosphate should be sprayed on the leaves, which is beneficial to promote flowering and preserve flowers and fruits.

3. Fertilize in autumn

In September and October, after the autumn fruits are harvested, it is recommended to apply urea + compound fertilizer or organic fertilizer + boron fertilizer, which will help the plants absorb and restore tree vigor, while maintaining autumn shoots and supplementing nutrition for later young fruits.

2. How to fertilize star anise?

1. Base fertilizer

Before planting the star anise tree , you should apply sufficient base fertilizer. You can choose well-rotted farmyard manure, and apply a small amount of phosphorus and potassium fertilizers, and an appropriate amount of nitrogen fertilizer. This can increase the quantity of fruits and improve the quality of fruits.

2. Topdressing

For topdressing of star anise trees, you can choose organic fertilizer, potassium chloride, urea fertilizer, etc., and adopt the method of digging trenches to apply fertilizer. Fertilization should be applied reasonably at different growth stages. For example, apply fertilizers to promote flowering and fruiting in May and June, fertilizers to strengthen flowers and fruits in July and August, fertilizers for harvesting fruit in September and October, fertilizers for wintering in October and November, and fertilizers to promote fruiting and strengthen shoots in February and March.

3. Foliar fertilizer

In addition to root fertilization, foliar fertilizer is also needed. You can spray potassium dihydrogen phosphate solution, urea solution, borax, etc. to promote flower bud differentiation and increase fruit setting rate.

4. Compound fertilizer

When applying fertilizer, you can use compound fertilizer, which contains multiple elements such as nitrogen, phosphorus, potassium, etc., which can meet the star anise's needs for multiple nutrients at the same time.

5. Organic fertilizer

The use of decomposed organic fertilizers can effectively improve soil structure and increase soil fertility, which is of great help in promoting the growth of star anise and enhancing the disease resistance of the plant.

6. Trace elements

Star anise trees will bear more fruits if they are applied with decomposed organic fertilizer or a mixed fertilizer containing nitrogen, phosphorus, potassium and trace elements such as boron. The fertilization time should be controlled in November-December and May-June each year. This can not only enhance the young fruit's resistance to wintering, but also increase the yield and quality of star anise that year.

The above is an introduction to what kind of fertilizers to apply to star anise to produce more fruits. When fertilizing the star anise tree, it is generally better to dig a ring-shaped trench and apply the fertilizer deeply. That is, dig a ring-shaped trench above the projection around the crown of the tree, spread the fertilizer evenly in the trench and cover it with soil. Apply 1-3 kilograms per plant each time, which is conducive to high and stable yields of star anise trees.
