The lychee colonization survives to the sapling period before fruiting. At this time, the main goal of management is to rapidly expand the canopy and lay the foundation for early fruiting and high yield. Therefore, in terms of management measures, it is necessary to strengthen soil management, cultivate a well-developed root system, promote a large number of shoots to shoot, and form a high-yielding tree. But because the root system is young and tender, it is very sensitive to fertilizer. Therefore, fertilization should master the principles of small amount, regular, timely and diligent application, and both fertilizer and water application. Litchi saplings usually shoot 4--5 times. Before each shoot, it is the rooting period. When rooting, there are many fine roots and it absorbs fertilizer quickly, so the best time to fertilize is before each shoot.

3 years after planting, fertilize more than 6 times a year; 3 years later, as the root system and canopy expand, the fertilizer can be gradually increased, and the frequency can be reduced year by year. For fertilization, it is better to open a 20-25 cm deep ring groove. The furrowing position should be 15 cm away from the fibrous roots. This fertilization method can induce the root system to expand and grow outward, and can continuously renew and germinate new roots. The amount of bio-organic fertilizer applied per plant is 1-2 kg.

Litchi enters the full fruit period 20-30 years after planting. During this period, the expansion of the root system gradually reached the maximum, the nutrient level has been improved, and the output has increased year by year, which consumes a lot of nutrients. Improper management of soil, fertilizer, and water during this period not only prone to large and small fruit, but also due to the reduced level of nutrient accumulation, vegetative growth declines, often accelerating tree senescence. The fruit of lychee is mainly autumn shoots. For example, autumn shoots are many and strong, which is the key to overcome the phenomenon of large and small lychees and ensure annual high yield. Therefore, after picking the fruit, apply a heavy fertilizer and appropriate watering to make the plants recover quickly. It is a key measure to strive for the new shoots to be drawn from August to September to provide more fruiting parent shoots for the second year of high yield, which can promote the differentiation of flower buds, which is a key measure to ensure a good harvest every year. The specific method is to loosen the soil 10 cm deep around the roots, apply 5--10 kg of biological organic fertilizer, and cover with a thin layer of soil after application.
