1. Perilla frutescens has strong adaptability to the environment. Generally, it can grow well where normal plants can grow normally. However, if it is planted in well-drained, fertile and loose soil with appropriate temperature and humidity, it will grow very vigorously and its yield and quality will be higher.

2. Under normal circumstances, live fans are generally used. There is generally a gap in sowing time between the north and the south in January. The sowing time in the south is generally in March, and the sowing time in the north is generally in the middle and late April. There are two kinds of direct seeding: ridge seeding and digging seeding. To sow seeds on the ridge, you can dig a shallow trench of about 1 cm on the ridge surface every 50 cm, then mix the seeds with fine sand and scatter them in the trench, and then cover it with a layer of fine soil. If crypt sowing occurs, it needs to be planted on the ridge at a distance of 40 cm in each row and 20 cm in each pig. After sowing, cover with a layer of fine soil and gently compact, and seedlings will grow in about 6-7 days.

3. When the seedlings grow to 15 cm, they can be transplanted. At this time, the weak seedlings should be removed and replaced with new seedlings. When planting, the intensity must not be too great, which will easily lead to root damage, weak nutrient absorption and different plant sizes in the later stage. At the same time, too close planting will also affect the weeding work in the future, so pay attention to the row spacing. After three months of planting, the plants will enter the vigorous growth period, and the demand for fertilizer and water will increase sharply at this time, so we should pay attention to watering and fertilizing the plants in time.

4. Perilla frutescens is also very particular about harvesting. Each part of perilla frutescens has different harvesting time and method. After the young leaves grow, they should be picked at any time, and it is best to pick them earlier. Generally, the seeds are around 10 month. After being cut with a sickle, they will be dried and threshed before being sold. As a medicinal material, you must choose to harvest it in a sunny place and dry it in time to avoid mildew. The middle perilla stem should be harvested after the spike grows, and it can be stored or sold in the shade to evaporate water.
