Lysimachia is a plant that typically does not flower or produce seeds in Jiangsu and Zhejiang provinces. Therefore, it is commonly propagated through cuttings or ramets. When using cuttings, the first step is to prepare a nutrient-rich soil mix for the seedbed. The recommended formula includes 70% garden soil, 15% decomposed organic fertilizer, and 15% alfalfa ash. To raise seedlings, the mixed soil is placed into containers, and water is added to the bottom. Cuttings are taken from healthy mother plants, selecting 3–5 shoots with 2 unfolded leaves, each about 10 cm long. Before planting, these cuttings are soaked in a naphthaleneacetic acid solution (1000 mg/l) for 5 minutes. Afterward, they are planted in the prepared soil. On sunny days, the soil should be watered several times daily to maintain proper moisture, and protection from heavy rain is essential.
Roots usually begin to develop within 3 days under suitable temperatures, and after about 15 days, the seedlings are ready for transplanting. Since Lysimachia can be harvested multiple times during its long growth period, and its stems and leaves grow vigorously, it's important to apply base fertilizer during site preparation. Typically, 1500–2000 kg of organic fertilizer is applied per 667 square meters. The planting density should be between 6,000 and 8,000 plants per 667 square meters, with spacing of 20–30 cm between plants. After planting, timely watering is necessary to support root establishment, especially during hot summer months when shading nets are recommended to protect the young plants.
Lysimachia can be planted throughout the year, but the best time for transplanting seedlings is between April and September. This allows the plants to establish themselves properly before the onset of extreme weather conditions. With proper care and management, Lysimachia can thrive and yield consistently over multiple harvests.
