Buddleja officinalis is a relatively common flowering plant in people's lives, and it can be seen in many regions of China. As more people grow it in various places, questions about its propagation have also drawn considerable attention. How does Buddleja officinalis propagate? What are the propagation methods for Buddleja officinalis? Below, the editor will walk everyone through it.
1. How does Buddleja officinalis propagate? Seed propagation
When it comes to how Buddleja officinalis propagates, it is mainly done through seed propagation. After countless trials by people, this propagation method still has a very high survival rate. Of course, the premise is that we must master the operating method and also be careful throughout the process. The specific details of seed propagation are given below, and interested friends can take a look.
2. Propagation methods of Buddleja officinalis
1. Substrate selection
Before propagating Buddleja officinalis, we first need to choose the soil, which is the step of laying a solid foundation and is very important. Generally, it is best to choose loose, fertile humus soil as the substrate. This kind of soil is rich in nutrients and has relatively good drainage and aeration, allowing the plant to absorb nutrients better.
2. Substrate disinfection
After choosing the substrate for Buddleja officinalis, we also need to disinfect it to avoid carrying pests and diseases that could infect the plant. When disinfecting, we can break it up and spread it flat under the sun to bake, or put it into an iron wok and stir-fry it over high heat. In this way, even if there are pests and diseases in it, they will be killed by the high temperature.
3. Seed germination promotion
In addition to substrate selection and disinfection, there is another pre-treatment we need to do before sowing, which is to promote germination of the Buddleja officinalis seeds. We can soak the seeds in warm water at 30-40°C for about 12 hours. Once the seeds begin to absorb water and swell, take them out and sow them. This can make the seeds germinate faster.
4. Sowing method
Before propagating Buddleja officinalis by sowing, we first need to apply an appropriate amount of base fertilizer into the substrate, then evenly scatter the germinated seeds on the soil surface. After scattering them, cover with 1-2 cm of soil and then water. When watering, it is best to use the immersion pot method, because Buddleja officinalis seeds are relatively small, and if watered directly, they are easily washed away.
5. Follow-up management
After everyone has successfully propagated it according to the above method, we can carry out follow-up care. There are also many points to pay attention to when caring for Buddleja officinalis, such as watering and fertilizing, all of which require particular care. If you do not know how to grow it, you can refer to the article on how to grow Buddleja officinalis, which contains detailed care instructions.
Propagation methods of Buddleja officinalis
Seed propagation of Buddleja officinalis
Generally, sowing propagation is carried out in autumn. Scatter the Buddleja officinalis seeds collected that year evenly on a prepared seedbed, rake it level, and cover with about 2-3 cm of soil, or sow in furrow rows with a row spacing of about 35 cm and a furrow depth of about 3 cm, using 1 kg of seed per mu. After mixing the seeds with plant ash, scatter them evenly into the furrows, cover with soil about 0.5 cm deep, and finally cover with grass, keeping the seedbed moist at all times. After sprouting, the grass cover can be removed. Grow the seedlings for 1-2 years, and after the seedlings reach about 1 m in height, transplant them. After digging out the young seedlings, properly prune the root system, and open holes for transplanting at a row spacing of 2 cm and a plant spacing of 2 cm. Plant one seedling per hole, cover with soil and press firmly, water with rooting water, and apply sufficient base fertilizer.
Division propagation of Buddleja officinalis
The roots of Buddleja officinalis have very strong sprouting ability. When transplanting, one plant can be divided into 2-3 plants for transplanting. Control a reasonable distance, generally with a plant spacing of 1 m and a row spacing of 2 m.

Ecological habits of Buddleja officinalis
Buddleja officinalis grows at an altitude of 200-2800 m in sunny hillsides, riversides, shrub thickets by villages, or forest margins. It has strong adaptability and can also grow in limestone mountainous areas.
Buddleja officinalis grows on hillsides, in mixed woodlands, by rivers, and in hilly areas, usually as a semi-shade plant.
Cultivation techniques of Buddleja officinalis: site selection and land preparation
Choose hillside land or riverside flat land with deep soil layers and fertile soil for planting. After selecting the land, deep plow 30-40 cm, rake finely and level, remove weeds, and make seedbeds 120-130 cm wide. Apply sufficient base fertilizer in the field, 1500-2000 kg per mu.
Field management
During the seedling stage, Buddleja officinalis should be loosened and weeded in time to keep the soil moist. A certain amount of nitrogen fertilizer or human and livestock manure water can also be applied to promote seedling growth. In the field, before the stand closes, loosen the soil and apply topdressing 2-3 times each year. After the stand closes, loosen the soil and apply topdressing once each year around November. It is advisable to apply decomposed human manure or urine, or apply 1500-2000 kg of barnyard manure per mu, to promote more flowers and buds. If drought occurs, water in time.
Harvesting and processing
Buddleja officinalis can bloom after 2-3 years of transplanting. Generally, in spring, harvest unopened flower buds and inflorescences, remove impurities, and sun-dry them. Store in a dry, ventilated place.
Propagation methods of Buddleja officinalis
Buddleja officinalis commonly uses seed propagation and division propagation.
Seed propagation
In spring and autumn, use seeds collected that year and scatter them on a prepared seedbed, rake level, and allow the seeds to enter the soil 2-3 cm, or sow in furrow rows with a row spacing of 30 cm, furrow depth of 3 cm, and sowing width of 10 cm, using 1 kg of seed per mu. When sowing, mix the seeds with plant ash, then evenly scatter them into the furrows, cover with a layer of plant ash, and keep the soil moist, building a shade frame or covering with grass. If drought occurs, spray water and soak the soil thoroughly. When the seedlings are about 10 cm tall, remove the shade frame and thin the seedlings, generally with a plant spacing of 15 cm. When the seedlings are 100 cm tall, transplant them to the field, digging holes at a plant spacing of 1 m and a row spacing of 2 m, with holes 30 cm deep, one plant per hole, cover with soil and press firmly, water, and apply sufficient base fertilizer.
Division propagation
Because the roots of Buddleja officinalis have very strong sprouting ability, plants generally grow in clumps. When transplanting, one plant can be divided into 2-3 plants for transplanting. Plant at a plant spacing of 1 m and a row spacing of 2 m.
Disease and pest control of Buddleja officinalis
Buddleja officinalis has very few diseases and pests, mainly red spider mites: they damage tender leaves and young buds. Control method: spray with 20% fenbutatin oxide wettable powder at 700-800 times dilution, or use a decoction of Sophora flavescens stems and leaves, add lime, and spray.

Pharmacological effects
Acacetin is similar to quercetin and has vitamin P-like effects. Oral administration to mice at 25-100 mg/kg can reduce formaldehyde-induced inflammation; 50-100 mg/kg can also reduce the permeability and fragility of skin and small intestinal blood vessels. Acacetin also has some antispasmodic effect on increased tension in isolated rat small intestine caused by barium chloride, histamine, acetylcholine, etc. If injected into rat small intestine (40 mg/kg) or given intravenously to rabbits (10-25 mg/kg), it can cause a brief, mild increase in bile secretion and has a relaxing effect on bile duct smooth muscle. Intravenous injection of 25 mg/kg in rabbits can slightly increase urine volume within 25-30 minutes (75%). In normal rats, it does not affect sleep time caused by cyclobarbital, but in rats with carbon tetrachloride hepatitis, it can shorten sleep time. Acacetin has low toxicity, with an LD50 of 933 mg/kg in mice. In isolated mouse small intestine specimens, with acetylcholine-induced spasm, the antispasmodic potency of acacetin is 75% of that of papaverine.

Economic value
Buddleja officinalis can extract aromatic oil and can also be used as a yellow food dye. The stem bark fibers are tough and can be used as a papermaking raw material.
Cultural Background and Folk Customs of Buddleja officinalis
In Xishuangbanna, Yunnan, when the dye-rice flowers bloom, the village women and children always go into the mountains in groups, singing mountain songs, pick clusters of dye-rice flowers and put them into bamboo-woven back baskets to bring home, either using the fresh flowers directly to cook rice or tying them in bundles with palm leaves and hanging them on fences or walls. Whenever there is a festive holiday or friends and relatives come to visit, people will take down the air-dried but still fragrant dye-rice flowers, boil them in water and cook rice. Whether dried or fresh, the dye-rice flowers turn yellow immediately after being boiled in clear spring water. The villagers filter the boiled dye-rice flower water and then steam glutinous rice with it; the steamed glutinous rice is golden yellow and carries a rich floral fragrance. In their hometown, the villagers also pound this golden yellow glutinous rice into baba that has color, aroma and taste all at once, either for their own consumption or as gifts for relatives and friends. Some villagers also use dye-rice flower water to dye yellow paper and make paper money, which they burn for the souls of the dead below the nine springs, expressing respect and remembrance for their ancestors.
Related Legends
Regarding the custom of the Dai people in Xishuangbanna liking to use Buddleja officinalis to make yellow "hao leng", there is also a legend that has been passed down. A long time ago, a family had a Buddleja officinalis tree two zhang tall growing in their courtyard. On this family's balcony, on one side she washed rice and vegetables. One day when the Buddleja officinalis was in full bloom, she placed the earthen basin holding soaked glutinous rice on the balcony under the tree. At night, a strong wind blew, and many Buddleja officinalis branches and flowers were blown down by the wind, and one branch of Buddleja officinalis happened to fall into the earthen basin. In the early morning of the next day, when the hostess washed the rice, she picked out the flower branch from the basin, but quite a few Buddleja officinalis flowers still remained among the rice. She put the rice into a wooden steamer and steamed it. After the rice was steamed, gusts of a special fragrance drifted out. When the hostess lifted the lid of the wooden steamer and looked, she was stunned, discovering that the usual white rice had become yellow rice, and its smell was also much more delicate than usual. The whole family was overjoyed, and after eating it, everyone praised it without end. From then on, this family used Buddleja officinalis to soak rice and steam glutinous rice. After this matter spread from one to ten and from ten to a hundred, the local people all knew that Buddleja officinalis could be used as a dye for glutinous rice. Dye-rice flower is also a symbol used by Dai sons and daughters to express loyal and unchanging love.
