What are the precautions for growing perilla? Key points explained in one article

You are probably no stranger to the perilla plant, because perilla is also very widely used in our daily life. It not only has extremely high medicinal value, but also very high edible value. It is grown in many places in our country, and some people even grow one or two plants in a flowerpot on their own balcony, which is both attractive and practical. So today let us take a look at the precautions for growing perilla, to help your perilla grow better.

1. Soil

Perilla has a very strong ability to adapt to the growing environment, but the choice of planting site is a basic condition for high perilla yields, so we can choose the soil most suitable for its growth according to perilla's growth habits. It is best to choose sandy soil or loam with sufficient light, rich organic matter and a complete drainage and irrigation system. Be very careful not to plant it in soil with very heavy clay, because then perilla will grow very poorly.

2. Temperature

In fact, the perilla we see also has quite good cold resistance, but perilla is actually a warmth-loving plant. Although it can also grow at lower temperatures, its growth speed and the quality of the perilla will not be very good. In order to improve the yield and quality of perilla, we need to manage the field temperature when planting. The most suitable temperature for perilla growth is about 16 to 22 degrees. It can tolerate low temperatures, but the temperature must not be lower than 1 degree, otherwise it will stop growing, or even freeze to death.

3. Sowing

Perilla is usually sown around March or April in spring. At this time the temperature begins to rise and there is sufficient rain, which meets the requirements for perilla growth, so the germination rate is extremely high. When sowing, we also need to pay attention to the sowing method. The most common are broadcast sowing and drill sowing. For broadcast sowing, note that the scattered seeds should be gently pressed into the soil, and they should be scattered relatively evenly, otherwise the seedlings will be uneven and later management will be more difficult. For drill sowing, note the trenching: the empty row spacing between each trench should be about 20 to 25 cm, which makes later field operations convenient.

4. Fertilizer and water

The roots, stems and leaves of perilla can all be used as medicine. Our main purpose is to promote the growth of the whole plant, and the most important fertilization for perilla is base fertilizer, mainly farmyard decomposed manure, while later topdressing is mainly nitrogen fertilizer. During its entire growth process, generally two to three topdressings are needed, mainly according to the growth of the perilla seedlings, to increase the yield of perilla. Next, pay attention to water management. After sowing, water once, and be sure to soak the soil thoroughly. Then, after the perilla sprouts, water once. Then water once after transplanting. Finally, water and drain according to the water needs of the perilla and the rainfall conditions.

5. Pests and diseases

The most common disease of perilla is rust, a fungal disease caused by excessive water in the field and failure to drain it in time. It mainly harms the leaves of perilla, but the plant will also be affected by the disease, eventually turning yellow and slowly rotting, and it is highly contagious. Therefore, in the early stage of the disease, the diseased plants need to be pulled out in time and disinfected. Finally, control it with sodium diquat and 0.2—0.3 degree Bordeaux mixture. Its most common pests include beetles, moths and stem borers. For these relatively common pests, we can use dimethoate emulsifiable concentrate, trichlorfon and fenitrothion respectively for control.
