Cultivation Techniques and Management Methods for Garden Balsam Seeds

Garden balsam seeds are the seeds of the garden balsam (Impatiens balsamina), a plant in the Balsaminaceae family. The garden balsam is also known by other names such as Xiaotaohong, Nail Flower, and Xiao Zihong, and is a minor, less-common medicinal herb. In recent years, because Chinese medicinal herb cultivation promotion agencies have not provided sufficiently scientific guidance, the proportion of medicinal herb cultivation has become unbalanced. The vast majority of herb growers have gravitated toward large-volume, commonly used medicinal herbs, while neglecting some less-common varieties that are genuinely effective and whose usage is on the rise. The result is often an oversupply and surplus of large-volume herbs. As a less-common variety, garden balsam seeds have promising cultivation prospects. According to relevant data, garden balsam seeds have shown remarkable results in cancer treatment in recent years, driving their usage and price up year by year. According to a report in China News of Traditional Chinese Medicine, the Bozhou Chinese medicinal herb market in Anhui alone sells 50 tons each year, and demand remains very strong. Cultivation and management of garden balsam are relatively simple, and it is suitable for cultivation throughout the country.

Propagation and Cultivation

Propagation: Propagate by seed. Seeds can be sown directly in the field or raised as seedlings for transplanting. Before cultivation, apply sufficient base fertilizer and level and finely harrow the soil. Direct sowing can be done from Qingming to around Lixia. Sow in rows at a row spacing of 60-80 cm with a furrow depth of 1.5 cm, cover with soil, firm it down, and water thoroughly. When the seedlings are about 10 cm tall, thin and set the plants at a spacing of 50-60 cm. For seedling transplanting, first prepare a seedbed, open horizontal furrows about 1.6 cm deep in the bed, evenly scatter the seeds into the furrows, cover with soil, level, and water. When the seedlings are about 10 cm tall, appropriately remove the overly dense seedlings. When the seedlings are about 15 cm tall, transplant them to the field at a row spacing of 60-80 cm and a plant spacing of 50-60 cm, and water after transplanting to preserve soil moisture.

Cultivation methods: In the early growth stage, water frequently and weed frequently. When the plants are about 30 cm tall, remove the lower leaves at the base, improve ventilation, pinch off the stem tips to encourage more branching, and remove the basal leaves. At the same time as removing the stem tips, open furrows between the rows and apply fertilizer, applying 600-700 kg of cake fertilizer per hectare, then cover with soil after application, but avoid applying chemical fertilizers. During intertillage and weeding, earth up the soil to prevent lodging.

Pest and disease control: A common disease is powdery mildew, which damages the leaves. After discovering diseased plants, use 0.3 degree Baume lime-sulfur mixture once a week for 2-3 consecutive times; appropriately increase ventilation and promptly drain away standing water. During the seedling stage, plants are susceptible to damage from cutworms; control methods are the same as for other crops.

Harvesting: Garden balsam seeds are harvested when the fruits are eight-tenths ripe. Because the seeds easily burst out of the fruit, they should be collected promptly as they are picked, cleaned of all impurities, and sun-dried. Garden balsam flowers are best harvested at peak bloom; avoid sun-drying and dry them in the shade. Garden balsam stems (Fengxian Tougu Cao), that is, the whole plant, should be cut promptly after the fruits are fully ripe. Dry them repeatedly in the sun to keep the color reddish-yellow, and avoid black mold.
