The Latest Wax Apple Fertilization Techniques and Methods Tutorial

Wax apple, also known as Java apple, purple Java apple, or water apple, is a nutrient-rich fruit that also has certain medicinal and health-care value. If you want the wax apple to produce more fruit, fertilization work must be done well, so how should the wax apple be fertilized? Let's take a look at the detailed introduction below.

1. Fertilizing young trees

For fertilizing young wax apple trees, the principle of frequent light applications should be followed, mainly with nitrogen and potassium fertilizers, to promote the start of growth in young trees. Never apply fertilizer heavily, as this may cause root burn, leading to poor root growth and, in severe cases, the death of young trees. Generally, within half a year of planting, a livestock manure and urine fertilizer at a concentration of 10%-15% should be applied once a month, which can promote the growth of new roots and new shoots in young trees. After that, fertilize once every 1-2 months, generally before new shoots emerge, to provide sufficient nutrients for new shoot growth.

2. Topdressing in stages

The wax apple has a relatively high fertilizer requirement. In the early stage, more phosphorus and potassium fertilizers should be applied. During flower bud differentiation, attention should be paid to the application rate of nitrogen fertilizer. If nitrogen fertilizer is applied excessively, it will cause vigorous growth and excessive vegetative growth. After the fruit expands, apply phosphorus and potassium fertilizers heavily to promote fruit development and improve yield and quality. Generally, before flowering, apply nitrogen, phosphorus, and potassium each accounting for 50% of the total fertilization amount; during the flowering and fruiting stage, apply the remaining nitrogen fertilizer and 25% of the phosphorus and potassium fertilizers; during the harvest stage, apply the remaining 25% of the phosphorus and potassium fertilizers.

3. Foliar spraying of fertilizer

When there are many fruiting trees, the nutrients absorbed by the root system at this time cannot meet the growth and development needs of the fruit. At this point, foliar spraying of fertilizer can be used to maintain the plant's nitrogen, phosphorus, and trace elements. In addition, when planting in coastal areas, the soil salinity is relatively high, so fresh water should be introduced to wash away salt, reduce the soil's salt content, improve soil structure, and allow the plant to grow normally.

4. Precautions

After flower induction in wax apple, attention should be paid to the supply of nutrients. During the flowering stage, attention should be paid to the supply of nitrogen fertilizer. During the flowering stage, attention should also be paid to the ratio of phosphorus and potassium fertilizers and the supply of trace elements, so as to avoid nutrient deficiency in the plant. During the fruit-increasing stage, high-potassium fertilizer should be supplied, and foliar fertilizer should be applied more to supplement trace elements that may be lacking, so as to ensure the nutrient needs of flowering and fruiting. During the flowering and fruiting stage, attention should be paid to the application of nitrogen fertilizer. Many fruit growers apply excessive nitrogen fertilizer in order to increase production, which leads to vigorous growth of branches and leaves, competing with the fruit for nutrients, resulting in poor fruit quality and a counterproductive effect.
