Why Doesn't the Miracle Fruit Bear Fruit? Latest Cause Analysis

Miracle fruit is a typical tropical evergreen shrub, native to West Africa, Ghana, and the Congo region. It is cultivated in Guangdong, Guangxi, Yunnan, and Hainan in China. It prefers high temperatures and high humidity, with an optimal growth temperature of 20-30°C. Cultivation should use well-drained, organic-rich acidic sandy soil with a pH of 4.5-5.8. Let's take a look below at why miracle fruit doesn't bear fruit!

When Does Miracle Fruit Ripen?

The fruit ripening period of miracle fruit is inconsistent, with peak fruiting periods usually in March, June, and October. The fruit is small and oval-shaped, turning bright red when ripe, with white juicy flesh, and is pollinated by ants and other insects. Miracle fruit was introduced to China in the 1960s and is now cultivated as an ornamental garden plant in many regions. It blooms small white flowers in September each year, sets fruit in October, and the fruit turns from green to red and ripens in November.

What Makes Miracle Fruit Mysterious?

Miracle fruit contains a taste-modifying protease (miraculin). Although it cannot truly change the taste of food, it can change people's sense of taste, so after eating miracle fruit, people find that any sour food tastes sweet. After eating miracle fruit, the miraculin distributes itself on the taste bud cell membranes of the tongue. In a neutral pH environment, the sweetness-receptor protein on the miraculin will not bind with the sweetness receptor site, so miraculin itself is not sweet. Therefore, the taste-changing function of miracle fruit is a safe change and is suitable for consumption as a daily food.

Why Doesn't Miracle Fruit Bear Fruit?

1. Lack of pollination: Fruit is the next generation produced by plant mating. If there are only male or only female plants, or if male and female cannot mate, the next generation cannot be produced, and of course fruit and seeds cannot be produced either. Therefore, pollination of miracle fruit can be helped artificially. The method is to raise flies next to the potted plant during the flowering period; flies can also pollinate effectively.

2. Environmental factors: During the flowering period of miracle fruit, the flowers and pollen have low resistance to the environment. Therefore, during the flowering period of miracle fruit, it is best to avoid factors such as low temperatures, cold waves, rainfall, and strong winds. In terms of artificial management, it is best not to water the entire plant, so that the pollen is not washed away.

3. Fertilizer issues: Using fertilizer with high phosphorus and potassium content before miracle fruit blooms can increase the fruit-setting rate of miracle fruit.
