Boron deficiency in dragon fruit
Dragon fruit is a tropical fruit that requires a well-balanced nutrient supply, including boron, for healthy growth and high fruit yield.
Symptoms of boron deficiency in dragon fruit, include:
- New growth deformities, particularly the tips of young shoots which may become distorted, withered, and eventually die
- Chlorosis, yellowing, and necrosis in the leaves, particularly at the edges
- Deformed or undersized flower petals which results in poor pollination and fruit set
- Uneven ripening, reduced size and poor quality fruits
In severe cases, boron deficiency can cause the stem of the dragon fruit plant to crack, leading to wilting, stunting, and death of the entire plant. Additionally, the fruits may be more susceptible to fungal and bacterial infections due to the weakened plant immunity caused by boron deficiency.
Preventing boron deficiency in dragon fruit
To prevent boron deficiency in the crop, it is essential to maintain a well-balanced nutrient supply and soil pH. A soil test can help determine the levels of boron and other critical nutrients in the soil. The nutrients absorbed and accumulated by the plant, as well as the nutrients that are exported in the fruits at the time of harvest, should also be taken into consideration.
Your boron fertilizer options for dragon fruit
The proper way to meet the requirement for boron in pitaya cultivation is through the application of soluble fertilizers that gradually release boron, enabling continuous compliance with the plant's demand for boron, especially during flowering periods.
When using Granubor® for soil application, we recommend applying in the canopy projection area with sufficient moisture in the soil to promote absorption. If using Solubor®, monthly foliar applications are recommended during the fruiting and flowering phase.
