Litchi Orchard Management

What is Litchi Farming and its Overview?

Litchi, scientifically known as Litchi chinensis, is a unique and tropical fruit tree belonging to the soapberry family, Sapindaceae. It originates from South China and has been widely cultivated throughout Southeast and South Asia. Litchi farming has a rich history, dating back to the 11th century in China. This tall evergreen tree produces small, fleshy, and delectably sweet fruits. The fruit’s outer shell is rough-textured, pink-red, and easily peels away.

Litchi seeds contain methylene cyclopropyl glycine, which, when consumed in large quantities by malnourished children, has been associated with hypoglycemia-related encephalopathy. Litchi chinensis is an evergreen tree with pinnate leaves of 4 to 8 elliptic-oblong to lanceolate leaflets. The bark is gray-black, and the branches have a brownish-red hue.

The tree blooms with terminal inflorescences, bearing panicles of fragrant white, yellow, or green flowers. Depending on various factors, the litchi fruit takes approximately 80 to 112 days to mature. It comes in different shapes, ranging from round to ovoid to heart-shaped, and measures up to 5 cm long and 4 cm wide. The thin, tough skin transforms from green to red or pink-red as it ripens.

Peeling reveals a layer of translucent white fleshy aril with a sweet flavor and a pleasant floral aroma. The fruit contains a single inedible dark brown seed that varies in size. Litchi fruits are commonly consumed fresh due to their delicate floral flavor, which is lost during the canning process. Some cultivars yield fruits with shriveled seeds, known as ‘chicken tongues,’ which often have a higher market value as they provide more edible flesh.

Importance of Month-Wise Planning for Litchi Orchard Maintenance

Month-wise planning for litchi orchard maintenance is crucial as it aligns with the specific needs of the trees at different stages of growth, optimizing tasks such as pruning, irrigation, fertilization, pest control, and harvesting for maximum productivity and fruit quality.

Best Tips for Growing Litchi Orchard Maintenance Practices

Climate: Litchi thrives in a temperature range of 25-35°C. It requires a rainfall of around 1200mm for proper growth. The sowing temperature should be 25-35°C, while harvesting is ideal at 25-30°C.
Soil: Litchi can be grown in various soils, but it prefers deep, fertile, well-drained soil with a pH of 7.5 to 8. Avoid high pH and saline soils as litchi cannot tolerate them.
Popular Varieties: Some popular litchi varieties include Calcutta, Dehradun, Seedless Late, Rose Scented, Saharanpur, Muzaffarpur, Khatti, and Gulabi. Each variety has characteristics such as fruit size, flavor, and maturity time.
Land Preparation: Plough the land, perform cross-plowing, and level it to prevent water stagnation. Proper drainage is essential for litchi cultivation.
Sowing: Plant litchi seedlings in pits measuring 1m x 1m x 1m. Fill the pit with topsoil, well-decomposed cow dung, bone meal, and MOP (Muriate of Potash). Transplant two-year-old plants or opt for direct sowing.
Propagation: Litchi is primarily propagated through air-layering. Select pest- and disease-free branches for air-layering and plant them in nurseries.
Pruning and Training: Train young litchi trees to give them a definite shape. Light pruning after fruit harvest promotes new shoot growth.
Intercrops: Intercropping can be practiced for 3-4 years to maximize land utilization. Suitable intercrops include peach, plum, kinnow, vegetables, and pulses. Remove intercrops when the orchard enters commercial bearing.
Irrigation: Provide irrigation at all stages of development. Young plants require frequent irrigation, while older plants can be watered once a week during summer. Apply irrigation twice a week during fruit development to minimize fruit cracking.
Plant Protection: Protect young plants from hot winds and cold waves by planting windbreak trees and growing Dhaincha around the plantation. Take preventive measures against pests like fruit borers, mites, leaf miners and diseases like downy mildew, anthracnose, root rot, red rust, and fruit rot.
Fertilizer: Apply well-decomposed cow dung, urea, SSP (Single Super Phosphate), and MOP (Muriate of Potash) based on the age of the crop. Adjust the fertilizer quantities accordingly.

The months of August to September, right after the monsoon season. This allows the young plants to establish their roots before winter. In some regions like Punjab, planting can be extended up to November.
Following proper spacing guidelines is important when sowing litchi seeds or transplanting seedlings. Maintain a distance of 8-10 meters between rows and individual plants if using the square planting method.
Dig pits of 1m x 1m x 1m and expose the soil to the sun for a few days. Fill the pits with topsoil mixed with well-decomposed cow dung, bone meal, and MOP (muriate of potash). Sprinkle some water after planting the seedlings in the middle of the pit.
Litchi trees can be propagated through air-layering, the preferred commercial method. Select 2-3cm in diameter and 30-60cm long branches, free from pests and diseases. Remove a 4cm wide bark ring with a sharp knife, place wet moss on the exposed area, and tightly wrap it with a polythene sheet.
After about four weeks, when many roots have developed, detach the air-layered portion from the mother tree and immediately plant it in a nursery. Provide irrigation to the newly planted air-layered trees.
Pruning and training are essential for shaping litchi trees initially, but excessive pruning is optional. Light pruning after fruit harvesting helps promote new shoot growth.
During the initial 3-4 years, intercropping can be practiced when the orchard is still in its slow growth phase. This provides additional income, enriches the soil, and helps control weeds. Quick-growing plants like peach, plum, kinnow, and certain vegetables and pulses can be intercropped. However, once the orchard reaches commercial bearing, it’s advised to uproot the intercrops.
Since litchi is cross-pollinated, pollination is done by insects and honey bees. Placing 20-25 boxes of honey bees per hectare ensures proper pollination and fruit set.
To protect young litchi crops from hot winds in summer and cold waves in winter, it’s recommended to plant suitable windbreak trees around the plantation. Growing Dhaincha around the litchi plantation protects during both seasons. Tall tree seedlings such as Mango and Jamun can also be planted around the litchi plantation to shield it from heavy winds.
Appropriate irrigation is crucial at all stages of development. Young plants require frequent irrigation, especially in summer, while older plants need irrigation once or twice a week.
Watering should be done after completing the fertilizer application. Water should be applied for frost protection at the end of November or early December. During fruit development, irrigation twice a week helps reduce fruit cracking.
Litchi orchards are prone to various pests and diseases. Fruit borers can damage fruits, while mites and leaf miners affect the leaves. Proper pest control measures such as releasing Trichogramma, using insecticides like Nimbicidine and Dichlorvos, and pruning affected portions can help manage these pests.
Diseases like Downy Mildew, Anthracnose, Tree decline and Root Rot, Red Rust, and Fruit Rot can also occur. Preventive measures like maintaining cleanliness, spraying appropriate fungicides, pruning operations, and providing proper drainage help prevent and manage these diseases.
Harvesting litchi is determined by the change in fruit color from green to pink and the skin’s smoothness. Harvesting is done in bunches, including a small portion of leaves and branches. Litchi fruits have a poor shelf life and should be harvested and stored at the right maturity stage for the best quality.
