How Many Years Until a Soapberry Tree Bears Fruit? A Detailed Explanation of the Fruiting Timeline
The soapberry tree, also known as round soap pod and golden tree, is a large deciduous tree. Its fruit is rich in saponin and can be used as a substitute for soap; it is a raw material for soil detergent. Its roots, branches and leaves, fruit and seeds can all be used as medicine, giving it very high application value. So how many years does it take for a soapberry tree to bear fruit?
1. How many years does it take for a soapberry tree to bear fruit?
A soapberry tree generally takes 5-6 years to grow to maturity and bears fruit once a year. Usually a single tree can produce from several dozen jin to over a hundred jin of seeds; a small tree may produce only a few jin. The fruit is spherical, turning yellow or brownish-yellow when ripe, and the seed inside is a black sphere.
2. How do you plant a soapberry tree?
1. Seed selection and seedling raising
There are many varieties of soapberry, and each variety differs; different varieties vary in yield, and also differ in saponin content and oil content. Therefore, choosing excellent varieties is a major task before planting, and good seed must be selected well. Store the seeds at the end of the year and plant them after spring begins the following year. Before planting, soak the seeds in warm hot water for one day, then use the sand bed germination technique before sowing; this way the germination rate is high. After the seedlings emerge, they grow extremely fast and generally can leave the nursery in one year. Cutting, root sprouting and other propagation methods can also be used, or grafting can be used to cultivate superior plants.
2. Site selection and afforestation
Soapberry is a light-loving, deep-rooted plant that prefers an environment with ample sunlight, so it is best to plant it on a sunny slope or a semi-sunny slope, requiring deep soil, loose and fertile soil, and well-drained slightly acidic soil. After choosing the afforestation site, thoroughly clear it in autumn, clearing weeds, shrubs and other plants, and removing dead branches and fallen leaves. Once this is done, dig planting holes at a spacing of 4×4 m, with a hole surface of 60×60cm, a hole depth of 40cm, and a hole bottom of 50×50cm. In January, apply about 3 kg of organic fertilizer such as barnyard manure or compost per hole as a base fertilizer. After fertilizing, fill in a layer of soil, mix it, and wait for transplanting.
3. Planting out
Dig up the young trees that have been cultivated for one year, taking care not to damage the seedling roots, then take them to the afforestation site for transplanting. Dig and plant promptly to ensure the survival rate. Set the young tree upright into the planting hole, spread the roots out in the planting hole without letting them twist together, then fill with soil. When the soil has been filled to half the planting hole, lift the young tree upward so its roots spread out, then continue filling and tamping the soil, and water it.
4. Forest management
One month after the young trees are planted out and have survived, fertilization can begin, once every half a year. Fertilization is mainly nitrogen fertilizer combined with phosphorus and potassium fertilizer, and the amount applied should be increased according to the age and size of the tree. During management, pay attention to changes in moisture. Soapberry fears waterlogging, so drain well during the rainy season to avoid root rot caused by standing water, and irrigate promptly during drought. When the young tree grows to 1 m, prune promptly to shape it, cutting off the terminal bud, keeping the main trunk, and promoting the growth of lateral buds to form a crown; this can increase yield.
