What causes dragon fruit to grow aerial roots

The reasons dragon fruit produces large numbers of aerial roots are roughly as follows:

1. Insufficient nutrition, it needs aerial roots to absorb water and nutrients.

2. Suitable climate, warm and rainy, the plant's climbing habit causes aerial roots to grow.

3. Unstable growth, it needs aerial roots to stabilize the plant.

Comprehensive analysis:

On one hand, aerial roots inherit the dragon fruit's climbing growth genes, growing at the tips of new shoots, by which the plant clings to its host and is held in place; on the other hand, field observations show that robust, short plants have fewer aerial roots, which is suspected to be related to some degree to nutrient deficiency.

Observations show that after rainfall and a drop in temperature, aerial roots send out white roots that can absorb a certain amount of nutrients. Moreover, since aerial roots have already grown, how should they be used under different planting methods?

Pillar-style planting: place drip irrigation lines at a certain height above the ground (higher than the aerial roots), and use the aerial root system to absorb nutrients when fertilizing through drip irrigation;

Row-style planting: aerial roots mostly grow where the plant meets the bamboo poles and at the tips of fruit-bearing mother branches. What the roots can mainly use is foliar fertilizer applied during routine spraying, or key spraying of components that the root system absorbs well, which can achieve good results.
