How to Grow a Baobab Tree? A Detailed Guide to the Latest Methods
The baobab tree is native to tropical regions such as Africa and Madagascar, China. Its canopy is very large, and the diameter of the main trunk can reach a size that two people cannot encircle with their arms. However, it is relatively fragile; a gun can shoot through the trunk. Every part of the baobab tree is useful. The fruit is rich in vitamin C and antioxidants and is called the “super fruit.” Even the leaves and bark can be used as medicine to reduce inflammation and bring down fever. Although it is native to Africa, it is also grown in tropical regions of our country, so how should the baobab tree be grown? Details are as follows:
1. Seed soaking and germination
The seed coat of the baobab tree is very thick and hard. If the seeds are placed directly into the soil before planting, their germination rate will be very low. Therefore, before sowing and planting, the seeds must be pre-treated to promote germination. There are many methods for promoting seed germination, such as mechanical scarification and seed soaking, but the soaking method is generally used. Soak the seeds in concentrated sulfuric acid for about 7 hours; after sowing, such seeds can achieve a germination rate of more than 90% at around three weeks. Although the mechanical scarification method can speed up seed germination, it produces certain side effects: it not only fails to improve the seed germination rate, but also affects normal growth.
2. Site selection and sowing
After the seeds have been pre-treated to promote germination, sowing can begin. Because the baobab tree is a fruit tree that grows in the tropics, the planting site must have sufficient sunlight, a certain water source, fertile soil, and a relatively deep soil layer. About one week after sowing, the seeds will begin to show white, and under normal growing conditions, the seeds will begin to germinate in about one month. However, after germination, they must be shaded for about one week before the seedlings can be fully exposed to sunlight. During the shading period, the seedlings need to gradually adapt to sunlight to avoid sudden changes in light causing the seedlings to fail to adapt and die. Then water at least twice a day, in the morning and evening, to ensure sufficient moisture for growth.
3. Water and fertilizer management
Water and fertilizer management for the baobab is determined by the weather conditions and soil conditions of the planting site, and the water and fertilizer requirements of the baobab tree differ at each growth stage. Young trees should be watered at least twice a week, generally in the evening or early morning. Although mature baobab trees do not need watering, proper watering can better promote the growth of the baobab tree. Before planting, a certain amount of base fertilizer must be applied, and after planting, additional topdressing and foliar fertilizer should be applied. If the purpose of planting is mainly for leaves, then more organic fertilizer should be applied. Spring and summer each year are the peak growing seasons for the baobab tree, so the required water must be supplied adequately.
4. Timely harvesting
The harvesting time and harvesting method of the baobab tree also require some attention. Without a correct harvesting method, not only will the yield be reduced, but the quality of storage and transportation after harvest will also be affected to a certain extent. It may even harm the tree itself and affect the yield of the following year. The generally suitable harvesting time is around October each autumn. When the bark turns dark gray or the trunk turns black, the leaves can be harvested. To harvest fruit of better quality, it is best to wait until the bark color turns pink or purple and the trunk turns red.
The above is a brief introduction to the cultivation methods of the baobab tree. The planted area of the baobab tree in our country has not yet fully developed, because the baobab tree is native to the tropics. It has relatively high environmental requirements, and in our country it is only grown in tropical provinces such as Hainan and Yunnan. However, the editor thinks that the baobab tree still has certain prospects for cultivation, because the baobab tree is very high in nutritional value: the shell of the fruit can be used as a ladle, the pulp can satisfy hunger, and the juice can quench thirst. Therefore, growers with suitable planting conditions may consider it.
