Longan is closely related to the litchi tree but grows more slowly in tropical climates. While it takes longer to acclimate and bear fruit than the litchi, longan trees have better survival rates once acclimatised.
Caring For Young Longan Trees
Longan trees can be propagated from seeds, air layers, grafting, and cuttings and grow best in semi-shade locations. Summer is a vulnerable time for unacclimated longan plants. Hence, providing mulching for moisture retention and facilitating rapid growth is essential. The seedlings are less likely to die after the first three years and need watering at least once a week.
Caring For Fruit bearing Longan Trees
The Sri Chompoo longan tree is expected to yield a heavy crop this year. However, the fruits are small, similar to litchi fruits. The fruits grow in dense clusters, which may strain the tree. Supporting the branches before the fruits develop can help prevent flower and fruit drops. The supports, which can be made of metal, bamboo, or wood, protect the branches from breaking due to the weight of the fruits. Branches are also at risk of breaking during thunderstorms and whirlwinds. Additionally, older trees need mulching and composted manure to thrive.
Longan Fruits
The litchi fruits are more susceptible to fruit flies than the Sri Chompoo fruits, which also face less pest pressure. The large trees need watering once a week or fortnightly. The fruits will be ready for harvest within three months. Sri Chompoo fruits are sweet and aromatic, with low acidity, so harvesting may begin before they are fully ripe. The fruits can stay viable on the tree for two to three months. Longan trees make attractive and productive additions to a subtropical garden.
