The flesh of the fruit turning black or developing a blackheart can be attributed to a deficiency in a specific mineral, such as boron, along with an insufficient water supply, leading to poor fruit ripening.
Recommendations are as follows:
- Add Baba Compost-based Fertilizer to the soil, applying approximately 10kg per tree or per 100 square feet once a month for two months.
- Then, in the third month, supplement with high-phosphorus and potassium fertilizer, such as Mr Ganick 258 Organic Fruit Tree Fertilizer, to help reduce this issue.
- Consistent and adequate watering is crucial, especially during dry periods. Water stress can exacerbate nutrient deficiencies and lead to poor fruit development.
