What are the propagation methods for Houttuynia cordata?
Houttuynia cordata is a traditional herbal medicine in China, with the effects of clearing heat and detoxifying, and strengthening the stomach and aiding digestion. Its tender roots are tender and crisp, slightly spicy with a fishy smell. In addition to being used as medicine, it also has extremely high edible value, making it a food and medicine dual-purpose ingredient. In recent years it has been deeply loved by people. Currently, wild Houttuynia cordata on the market is far from meeting the demand, so artificial cultivation is needed. So do you know how it should be propagated?
1. Division propagation
Houttuynia cordata can be propagated by division, and division propagation is mainly carried out in spring and summer. First, dig out the mother plant of Houttuynia cordata. It can be planted directly, or it can be divided into several plants and then planted separately, or after dividing, it can be divided and planted in a seedbed. Houttuynia cordata has strong regeneration ability. After division propagation, the divided plants will soon be the same as the mother plant.
2. Cutting propagation
Cutting propagation of Houttuynia cordata is also stem cutting propagation, and it is also mainly carried out in spring and summer. Before doing it, first select the cuttings. You can choose a mother plant that grows robustly and has no pests or diseases, and cut off its better-growing branches as cuttings. When cutting, generally choose fertile, loose, well-drained sandy soil and insert the cut cuttings into it. Pay attention to watering, keep the soil moist, and also pay attention to light intensity. Once the light is too strong, shade it in time. After rooting, it can be transplanted.
3. Tuber propagation
Houttuynia cordata can also be propagated by tubers. Tubers refer to the underground rhizomes of Houttuynia cordata, and this is generally done in early spring. In February or March, dig out the underground rhizomes of Houttuynia cordata. The tubers are required to be white in color and relatively thick, and cut the tubers into small sections. Each section should retain 1-2 axillary buds, so that the survival rate after planting is high. Then, when planting in furrows on the seedbed, pay attention to placing the axillary buds upward to facilitate seedling emergence.
4. Propagation precautions
When propagating Houttuynia cordata, keep the soil fertile and rich in organic matter. Before planting, water frequently to keep the soil moist. After the seedlings grow, begin fertilizing, mainly with nitrogen fertilizer. Also pay attention to the harm of pests and diseases, especially at the turn of spring and summer, which is a period of high incidence of diseases, so pay special attention.
