Dragon fruit can not make calcium, magnesium and phosphorus fertilizers.

Due to the long harvest period of dragon fruit, organic fertilizer should be reapplied every year, and nitrogen, phosphorus and potassium compound fertilizers should be applied in a balanced and long period. During the flowering and fruiting period, potassium and magnesium fertilizer should be supplemented to promote the accumulation of sugar in the fruit and improve the quality. Keep the soil moist during the fruiting period, and the tree trays are covered with grass or mushroom residue.

When the weather is dry, irrigate once every 3-4 days. Dragon fruit, like other cacti plants, grows less than conventional fruit trees. Therefore, fertilization should be based on the principle of sufficient, small amount, and multiple times.

The 1-2-year-old young trees are mainly fertilized with nitrogen fertilizer, which can be applied thinly and diligently to promote the growth of the tree. Mature trees over 3 years old should be mainly fertilized with phosphorus and potassium fertilizer, and the amount of nitrogen fertilizer should be controlled.

Fertilization should be carried out in the spring shoot germination period and fruit expansion period, fertilizer is generally based on dry cake residue, chicken manure, pig manure according to 1:2:7 formula, 25 kg of organic fertilizer per plant per year.

Or in July, October and March of the following year, each plant is applied with kilograms of cow manure compost and 200 grams of compound fertilizer.

In addition, after the formation of each batch of young fruits, magnesium sulfate + borax + potassium dihydrogen phosphate was sprayed once outside the root to improve the fruit quality.

Due to the long harvest period of dragon fruit, organic matter fertilizer should be reapplied, and Hekai nitrogen, phosphorus and potassium compound fertilizer should be applied in a balanced and long-term manner. Completely use fertilizer with too high nitrogen content in pig and chicken manure, so that the branches are thicker, dark green and very brittle, easy to break when the wind is strong, and the fruit is really large and heavy, poor quality, low sweetness, and even sour or salty.
