When to Apply Swelling Fruit Fertilizer to Water Chestnuts
Compared to the general knowledge of most people about when to apply swelling fruit fertilizer to water chestnuts, please refer to the detailed introduction below.
When to Apply Swelling Fruit Fertilizer to Water Chestnuts
During the expansion period of water chestnuts, apply nitrogenous water-soluble fertilizer. In the expansion period of water chestnut plants, fertilize every 7 days, controlling the amount of fertilizer to about 40kg per mu each time. Later, adjust the fertilization according to the growth of the plants. The planting time of water chestnuts needs to be determined based on the climatic conditions of the planting area. In August, apply seed fertilizer, with about 20kg of special compound fertilizer for water chestnuts per mu.
Water chestnuts are a well-known plant, not only eaten as fruit but also as a vegetable. In the past two years, the price of water chestnuts has risen, higher than many fruits. So, how to fertilize water chestnuts to achieve high yields?

Then, adjust the fertilization according to the growth of the plants.
During the fruiting period, fertilize according to the growth of the plants, controlling the use of nitrogen fertilizer to about 120kg per mu.
What Fertilizer is Best for Water Chestnuts in the Later Stage
In the later stages of planting, it is good to use urea, compound fertilizers with nitrogen, phosphorus, and potassium. Use farmyard manure as a base fertilizer in the early stage and apply a solution of urea and compound fertilizers in the later stage. It is essential to dilute the concentration before use to prevent fertilizer damage.
Planting earlier can effectively increase yields. The general planting time is around July to August, and the latest should not exceed October. During the planting period, ensure adequate water, higher temperatures, and sufficient sunlight.
How to Fertilize Water Chestnuts for Best Results
Water chestnuts have a high tolerance for fertilizers and require sufficient organic fertilizers, supplemented with compound fertilizers. The principle is to "apply a heavy base fertilizer, skillful top-dressing, and supplemented with trace elements." Note that the fertilizer should not be too concentrated; for late-season water chestnuts, apply more top-dressing with fast-acting fertilizers.
1. In the early growth stage when the mother plant starts to form, the nitrogen content in the plant is higher. The nitrogen content is the lowest when the stolon for pod formation is produced, and a large amount of nitrogen is needed for tillering and leafy stem growth.
2. The peak period of phosphorus content is during the tillering and plantlet growth stage, then it gradually decreases. Phosphorus should be applied as a base fertilizer.
3. The potassium content in the plant is much higher than nitrogen and phosphorus. The peak period for potassium absorption is during tillering and pod formation. In addition to applying potassium as a base fertilizer, it is especially important to supplement potassium fertilizer in the middle and later stages.
The above is a comprehensive introduction to when to apply swelling fruit fertilizer to water chestnuts, hoping to provide green plant enthusiasts with some related knowledge about green plants.
