Litchi Cultivation Guide – Planting to Harvesting and Marketing
Importance of Litchi:
- Litchi is one of the most important subtropical evergreen fruit trees which grow well in the country.
- Litchi fruit is famous for its unique taste, flavour and color.
- At present annual production is about 44145 metric tons from 4463 ha.
- It can be grown all over the country. But its commercial cultivation is concentrated in the greater Rajshahi, Dinajpur, Pabna, Kushtia, Jessore, Mymensingh and Chittogong.
- The litchi grows under a wide variety of soils but performs better in deep well drained loamy soil having pH 6.5 to 6.8.
- It is adapted to the tropics and warm subtropics, cropping best in areas with winters that are short, dry and cool (temperature bellow 20 to 220 C) but frost free, and summer that are long and hot (temperature above 250 C) with moderate precipitation (1200 mm) and high humidity.
- There are a number of cultivars/land races growing in different areas of Bangladesh. These are Bedana, Bombai, Rajshahi Local, Mangalbari, Kadmi and Kalipuri. Introduced varieties are China-1, China-2, China-3, Muzaffarpuri and Madrajee.
- BARI has developed four improved varieties of litchi namely BARI Lichu-1, BARI Lichu-2 and BARI Lichu-3 and BARI Lichu – 4.

- The land should be ploughed 2 to 3 times.
- Perennial weeds are to be eradicated carefully and the land should be leveled well for facilitating irrigation.
- In hilly areas litchi is planted small hills with gentle slopes on the terrace. The soil is not ploughed, only small crescent shaped pits are made keeping the soil undisturbed.
Planting of Litchi Tree
- One year old air layerage having uniform growth should be selected for planting.
Planting system and spacing:
Generally the planting system practiced for litchi is the square system in the plains and contour in the hills. Triangular system can also be followed in the plains. Litchi saplings are usually planted 8-10 m apart both ways.
Planting season :
The best time of planting is May-June which may help in the establishment of young plants. Planting may also be done during August-September where there is scope of irrigation.
Pit preparation and transplanting
- Two weeks before planting pits of dimension 1 m × 1 m × 1 m is to be dug at the desired place.
- The soils are mixed with manures and fertilizers like cow dung (20-25 kg), ash (10 kg), TSP (500-700 g), MP (350-450 g), gypsum (200-300 g) and zinc sulphate (40-60 g) and the pits are filled with the same.
- A basket of soil from a litchi orchard which contains mycorrhizal fungi should be added.
- A small hole is made at the centre of the pit and the sapling is planted keeping the trunk upright.
- Water should be applied and the sapling should be staked immediately after transplanting.
- Fencing should also be provided.
Manuring and fertilization
- It is a well established fact that acute shortage of N, P and K hamper vegetative and reproductive growth of litchi.
- Micronutrients such as Zn, B and Cu also play important roles in litchi nutrition in the deficient soils especially with regard to flowering, fruit-set, fruit retention and fruit quality.
- The following doses of manure and fertilizer may be applied:
Age of plant
|1-4 years||5-10 yrs||11-20 yrs||> 20 yrs|
|Cow dung (kg)||10-20||20-30||30-50||50-60|
|Zinc sulphate (g)||10-15||15-20||20-40||50|
Manure and fertilizers should be applied in two installments, once in May to June (just after harvest) and another in September-October at the end of rainy season. These may be applied is broadcast or trench method but there must be irrigation of the soil after each application of fertilizer.
Training and pruning
- Training of litchi plants during the early years is necessary to provide a good framework.
- Training and pruning of tree start in the nursery and continue during tree establishment.
- Once the desirable shape and strong framework is achieved, no pruning usually necessary, except removal dead or diseased branches, cross limbs and mite-infested twigs.
- Pruning is done indirectly when a part of shoot bearing the cluster of fruits is removed during harvesting.
- Heavy pruning causes profuse vegetative growth resulting in poor fruiting.
- Irrigation is necessary during fruit-setting and development.
- The soil moisture and relative humidity remains very low during this period, which results poor fruit-set, promotes fruit drop and retards fruit growth.
- Heavy rain following prolonged draught causes fruit crack.
- Young plants also suffer due to shortage of water resulting poor growth and some times death.
- Irrigation at fortnightly interval after fruit set gives good harvest.
- Sun-burning and skin-cracking of developing fruits can be serious problems in litchi and are promoted by high temperature, low humidity and low soil moisture.
- Inadequate moisture during early period of fruit growth results in skin becoming hard and inelastic, and it may crack as a result of rapid aril growth following heavy rain.
- Frequent irrigation during the critical period of aril growth, spraying of zinc sulphate (1.5%) at weekly intervals starting from pea stage of fruit growth to harvest or spraying of GA3 at 40 ppm reduce the incidence of fruit cracking.
Pest and diseases and their management
The insect bores near the peduncle and enters into the nuts. Infestation of the pest occurs during pea stage of fruit and causes fruit drop and reduction of market value of the fruit drastically.
- Clean cultivation
- Removal and damage of infested fruit
- 2-3 sprays with ripcord/cymbush @ 1 ml/L of water at 15 days interval starting from pea stage of fruit
Litchi stem borer:
The insect bores into the stem and enters 150-250 mm and feed on bark. Later on they feed on woody portion. In case of severe infestation the plant becomes weak. Infested young plants may die.
- Killing the larva inserting metallic spoke
- Holes should be injected with kerosene/Petrol/0.02% Dichlorovos ant then sealed with mud.
Tender leaves, flowers and young fruits are affected by the pest. Infested leaves show curling and velvety appearance. Infested flower fails to set fruit and infested fruit does not develop properly.
- Collection and burning of infested twigs.
- Application of accaricides like Omite @ 1.5ml/l of water 2-3 times at 15 days interval during appearance of new vegetative flush and inflorescence.
White powdery materials are found on the panicles and flower buds. The affected flowers do not set fruit and are dropped off.
- Application of Tilt 250 EC @ 0.5 ml/L of water or Thiovit @ 2 g/L of water during panicle initiation (before flower opening and at fruit-setting stage (pea stage)
Brown spots are found on new leaves and the new shoots start drying. Young plants may if infected severely
- Removal and destruction of infected shoots
- Application of Tilt 250 EC @ 0.5 ml/L of water or Mancozeb /Pencozeb @ 2 g/L of water
Bat is the number one pest of litchi. They can damage total crop within short time during fruit development and maturity stage. Bats become more aggressive in cloudy nights. During these critical times negligence of short period can cause massive destruction.
- Creating sound by beating metallic sheet or split bamboo, bats should be chased away
- Covering the tree canopy by nets, attack of bats can be prevented
- Watching the orchard manually and focusing lights, bats can be drive away
- Maturity of fruit is judged by color development, flatness of tubercles and comparative smoothness of epicure.
- The fruits are harvested in bunches with few leaves. It helps prolonging the shelf life of fruits.
- The fruits should not be harvested immediately after rain when the trees are wet as the spoilage of the fruit in storage would be high.
- Fruit should be harvested early in the morning or in the afternoon.
- Noon time should be avoided because bright sunshine and high temperature enhance respiration and shorten storage life.
- After harvesting, the fruits should be kept in cool, dry and well-ventilated room to maintain its freshness.
- A good packaging, careful handling and an efficient transport system will ensure supply of litchi fruits to the consumers in an acceptable condition at a minimum cost.
- In Bangladesh, fruit are packed in bamboo baskets lined with litchi/mahogany leaves.
- Litchi fruits remain fresh in such baskets packed loosely for about 48 hours.
- Litchi fruits are highly perishable.
- The fruits for local market should be harvested at full ripe stage as indicated by attractive skin colour
- For distant market, the fruits are harvested slightly early, when they have just started to turn red.
- For distant city markets the fruits are harvested in the afternoon and then packed in the field loosely in small basket and reach the whole sale market during night from where the fruits are distributed to the retailer.
