The temperature of the protective ground during planting can not be lower than 5°C, and the optimum growth temperature is usually 25 to 35°C. It is advisable to use decomposed organic fertilizer. It is advisable to apply 1 to 2 tons per acre before planting. Sandy soil should be selected for planting sites, with high calcium and humus content, neutral or slightly acidic pH, and good drainage conditions. It is advisable to immerse the stem in 1/2 of the soil in the cuttings, and in the semi-dry and semi-humid conditions, plant the roots for 15 to 20 days and then water them. The stems are planted against the sun, allowing them to receive sufficient light in the afternoon and evening. It is advisable to plant about 2,000 plants per acre with a protective plastic film, with a row spacing of 80 to 95 cm and a spacing of 30 to 35 cm. Cutting too early will affect production, and late cutting will have a strong acidity. Therefore, we must master the time for cutting. The third generation of stem tablets can be eaten directly for vegetables. Generally the tender pieces are cut within 20 to 35 days. The tender stem pieces are fragrant and delicious, and the older the acidity, the higher.
