Causes of yellowing of dragon fruit branches and remedial measures

The branches of dragon fruit can directly reflect the growth of dragon fruit, and the sturdy and green branches are what every dragon fruit grower wants to see, but some growers often encounter the phenomenon that the branches suddenly turn yellow in the process of cultivation. So what causes the dragon fruit branches to turn yellow? Let's take a look.

1. Rotten root

The yellowing of dragon fruit branches may be caused by rotten roots, and the cause of rotten roots is that the roots are overwatered, resulting in no way to absorb nutrients, resulting in suffocating rotten roots; second, root diseases, root diseases occur, dragon fruit for nutrient and water absorption plummets, branches also appear yellowing or lack of water symptoms due to lack of nutrition, showing dry shrunken and withered.

Remedy: after watering, pay attention to the amount of water and times of watering. Root diseases can be prevented by alternative spraying of copper hydroxide, thiophanate methyl and propiconazole EC, and sprayed every other half a month until they return to normal.

2. Lack of water

The root system of dragon fruit is shallow, avoid waterlogging, but like fertilizer and water, so it should provide sufficient water in the whole growing period of dragon fruit. If the soil is dry or not watered for a long time, the moisture emitted by plant transpiration can not be maintained. Over a long period of time, the branches will be yellowed and shrunken.

Remedial measures: regular watering to keep the soil moist, but also can not accumulate waterlogging, in the long-term absence of rainfall to appropriately increase the number of watering, especially in the high temperature season, plant transpiration consumes a large amount of water, should be replenished in time.

3. Iron deficiency

Although the demand for trace elements in dragon fruit plant is small, it is also indispensable. Once the plant is lack of iron, it will appear the phenomenon of leaf yellowing.

Remedial measures: for diseased farmed plants, low concentration of ferrous sulfate solution or mixture of copper sulfate, ferrous sulfate and lime can be sprayed before germination, which can well control the phenomenon of iron deficiency.

4. Improper use of fertilizer.

When topdressing too much fertilizer or using raw fertilizer which is not fully fermented and mature, it will burn the root system of dragon fruit and affect the absorption of nutrients by the root system, resulting in the yellowing of branches. In addition, the use of fertilizer is insufficient to supply plant growth in time, especially when the amount of hanging fruit is large, the phenomenon of hanging fruit or branches suddenly turning yellow is often seen during planting, which is caused by fruit growth and branches scrambling for nutrients.

Remedial measures: fertilization must be carried out according to the actual situation of the plant, more should be reduced, less should be replenished in time, and it should be noted that only fully mature organic fertilizer can be applied.

The above is the introduction of the causes and remedial measures for the yellowing of dragon fruit branches. I hope I can help you. If you want to know more about it, please follow us.
