What precautions are there for growing Houttuynia cordata (fish mint)?
Houttuynia cordata has strong adaptability to the environment. Previously, it mostly existed in the wild, but due to increased market demand, unlimited digging of wild Houttuynia cordata has led to a sharp decline in wild resources. To meet market demand, the scale of artificial cultivation of Houttuynia cordata has been increased. So what problems need attention when growing Houttuynia cordata? Let's learn about the precautions for growing Houttuynia cordata together below.
1. Growing environment
If you want a high yield of Houttuynia cordata, there are still certain requirements for the growing environment. Houttuynia cordata has the characteristics of liking warmth, liking fertility, liking moisture, not tolerating saline-alkali soil, fearing strong light, and being slightly cold-tolerant. So the soil of the planting site is best chosen as a plot with loose soil texture, good water and fertilizer retention, sufficient fertility, and shade. Heavy clay, clay, and saline-alkali land are all unsuitable for growing Houttuynia cordata.
2. Planting density
When planting, we need to pay attention to the planting density of Houttuynia cordata. A reasonable planting density is beneficial to the yield and quality of Houttuynia cordata, and a reasonable density also makes later field management operations much more convenient. Generally, the seed usage per mu of Houttuynia cordata is controlled at about 300 kg, that is, the row spacing for planting is 25 to 30 cm, and the plant spacing is 8 to 10 cm.
3. Water management
The growth of Houttuynia cordata has a great demand for water, so water management must be done well, otherwise it will affect the normal growth of Houttuynia cordata. After planting Houttuynia cordata, water it immediately, and water it in time when encountering high-temperature and drought weather. At the same time, keep the soil moist and do not allow drought to occur. After Houttuynia cordata emerges, watering Houttuynia cordata should be changed to sprinkler irrigation to avoid soil compaction. When there is too much water in the field, drainage is also needed to avoid root rot and affect the yield of Houttuynia cordata. During the growth of Houttuynia cordata, multiple waterings are needed, mainly according to the weather conditions and its growth conditions.
4. Later topdressing
Topdressing is also an important issue we need to pay attention to. Houttuynia cordata has strong reproductive ability, so for it to reproduce, the nutrients required are also relatively large, so we need to carry out multiple topdressings. Topdressing is mainly applied by watering with human and livestock manure and urine water, once every half a month, which is very good for the growth and reproduction of Houttuynia cordata. Of course, we can also apply urea diluted with water, or apply it in holes. The effects of promoting seedlings and stimulating seedlings are both very ideal.
Houttuynia cordata is really very easy to grow, and the management work is also very simple. Under normal planting conditions, the per-mu yield of Houttuynia cordata is also very considerable. However, if everyone can understand more knowledge and information about growing Houttuynia cordata, this will further improve the yield and quality of Houttuynia cordata.
