The dragon fruit is more heat-resistant, water-resistant, and prefers warm, moist, sandy soil rich in organic matter.

Because of the long harvest period of dragon fruit, to reapply organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer should be balanced long-term application. Completely applied pig, chicken manure containing nitrogen too high fertilizer, so that the branches are more fat, dark green and very brittle, easy to break when the wind, the fruit is larger and heavier, poor quality, low sweetness, and even sour or salty taste. Therefore, the flowering and fruiting period to increase the application of potash fertilizer, magnesium fertilizer and bone meal, in order to promote the accumulation of fruit sugar, improve quality.

Fertilizer requirements of dragon fruit is large, before planting, be sure to apply sufficient basal fertilizer, fruit seedling growth, monthly fertilizer 2 to 3 times, nitrogen, phosphorus, potassium with, according to the different fertility of fruit trees, change the proportion of nitrogen, phosphorus and potassium and increase the amount of weight loss; appropriate supplemental application of micronutrients; each year and then increase the application of organic fertilizer 1 to 2 times. Adequate water and fertilizer conditions are the key to high and stable production of dragon fruit.

The dragon fruit stems on the shelf and then bent down about 1 meter, that is the beginning of flowering. Flowering and fruiting period each time need sufficient water and fertilizer to meet the requirements of dragon fruit. There is a high input to high output. Dragon fruit grows well, the most important thing is to see its trigonous stem grow full, there are enough nutrients to supply the growth of flowers and fruits. If the trigonous stem is flat, even if it can flower, the fruit is small and the commercial rate is low.

The dragon fruit flowering period lasts a long time, nutritional consumption is greater, the demand for fertilizer is greater, especially into the bloom period, it should be strengthened fertilizer management.

The proportion of nitrogen, phosphorus and potassium needed by dragon fruit is generally 1:0.7:1.3, which can be seen that dragon fruit is a potassium-loving fruit trees.

The dragon fruit, like other cactus plants, grows less than conventional fruit trees, so fertilization should be sufficient, small, many times as the principle.
