What are the growing conditions for longan? A detailed explanation of the latest cultivation requirements

Longan is a common tropical and subtropical fruit. It has relatively high nutritional value, and after being dried it is called guiyuan and can be used as medicine. It has a good nourishing and tonifying effect, can benefit the heart and spleen, and replenish qi and blood. Its effects are powerful, making it a fruit with relatively high economic value. So what conditions are needed for growing longan? Let's take a look together.

1. Temperature requirements

Longan is suitable for growing in warm climatic conditions. It can grow normally in any area where there is no frost in winter or only brief light frost. Its annual average suitable growing temperature is 21-23 degrees, and in January the temperature is 12-16 degrees. In winter it must not be lower than minus 1 degree. If the temperature is lower than 0 degrees, its seedlings will be frozen and easily die. When the temperature is lower than minus 4 degrees, adult plants will also suffer varying degrees of freeze damage. Therefore, before growing longan, you must first check whether the local temperature meets its growth needs.

2. Soil requirements

Longan does not have strict soil requirements. It can also grow normally in poor, dry, and acidic soil, but if the plot has sandy loam on the surface and clay underneath, the plants will have a shorter lifespan, lower yield, and poor economic returns when longan is grown. Longan is suitable for planting in soil with a deep soil layer, loose texture, good drainage, and good permeability. Before planting, the soil can be plowed and organic fertilizer applied as base fertilizer, so that longan can grow better and the yield will be very high.

Longan is a fruit tree that likes moisture and tolerates drought, but it fears waterlogging. Throughout its entire growth period, its water requirements differ at each growth stage. From autumn shoots to spring shoots, its water requirement is relatively low. Only in this way can it avoid sending out winter shoots, accumulate more nutrients, and benefit flower bud differentiation and flowering and fruiting the following year. In summer, in July-August, its water requirement is relatively high. If there is a shortage of water during this period, it will affect the growth of the root system and branches and shoots, thereby affecting yield and quality. When the fruit is about to mature, its water requirements are also extremely high. Long drought followed by sudden rain and long rain followed by sudden drought can both cause fruit cracking and fruit drop, so water regulation must be done well.
