Ganapathi Naragam (Layer) Fruit Plant

Pomelo is the largest member of the citrus family. It is sweeter than sour, with juicy flesh and pulp, and is considered one of the ancestors of grapefruit. Pomelo is believed to have originated in China and is mentioned in several Chinese historical records. It is mainly cultivated in China and Southeast Asia and is now widely available in countries like the United States and India.
The outer layer of the fruit is thick but soft and can be easily peeled. The pulp inside ranges in color from yellow to pink and red. Pomelo grows in tropical climates, especially during the summer season. The fruits can weigh 1 to 2 kg and have a mixed taste—sweet like orange, tart like grapefruit, tangy like tangerine, and highly juicy.
Pomelo is rich in nutrients, especially Vitamin C and Vitamin B. It contains beta-carotene and folic acid, making it beneficial for pregnant women. It also provides potassium for heart health. Additionally, pomelo contains Vitamins A, B1, B2, and C, bioflavonoids, healthy fats, protein, fiber, antioxidants, and enzymes.

Maintenance of Pomelo Trees

Once a plantation is established, care must continue regularly. The trees need protection from weather conditions, fire, insects, fungi, and animals. Various cultural practices may be required depending on the purpose of cultivation and environmental conditions.

Fertilizing Pomelo Trees

Along with organic manure, chemical fertilizers are required for better yield. Foliar fertilizers can also be applied to each new flush. An NPK combination of 13-13-21 is commonly used to improve fruit quality and taste. It should be applied in two doses: the first before flowering and the second after 5 to 6 months. Fertilizer dosage should be increased annually based on trunk growth. Foliar spraying is also recommended every 20 days, starting from 40 days after planting until 140 days after fruit set.

Watering and Weed Control

Young pomelo trees should be watered regularly until they are fully established. In dry climates, mature trees should be watered deeply at least once every one or two weeks, while desert regions may require more frequent irrigation. Mulching around the base helps retain moisture. Weed control is also important, and all weeds should be removed within a 1.5-meter radius around the plant.

Pruning and Tree Shaping

At 4–6 months after planting, pomelo trees are pruned to encourage branching. This is done by top pruning at about 30–40 cm from the ground. Three main branches are selected, evenly spaced in different horizontal directions to form a strong structure.

Pests and Diseases in Pomelo Trees

All fruit trees have the potential for pest and disease problems depending on location and weather conditions. Disease-resistant varieties are recommended for easier maintenance. Proper care practices such as watering, fertilizing, pruning, spraying, weeding, and seasonal cleanup help reduce the risk of insect and disease attacks.

Harvesting Pomelo

Pomelos are harvested at maturity, usually 140–160 days after fruit set. As the fruit ripens, the dull skin becomes brighter and oil glands become more visible and shiny. This ripening change starts from the tip of the fruit and moves toward the stalk.
