The cultivation methods of LYSIMACHIA christinae include: pot soil selection, lighting requirements, temperature requirements, reasonable watering, scientific fertilization and matters needing attention.

1. Selection of pot soil

It is best to use weak acid flower soil which is fertile, breathable and has good water retention. The soil for raising copper grass is mainly garden soil, mixed with a small amount of river sand and base fertilizer to make its flower soil. You can also mix humus soil, river mud, garden soil and river sand according to the ratio of 5: 2: 2: 1.

2. Lighting requirements

Desmodium styracifolium is shade-tolerant, preferably in semi-sunlight or shady places. Avoid strong direct sunlight. The more shady the environment, the more likely it is to lead to leaf rot. Copper money grass does not win glory, but it will grow better if it is exposed to scattered light for 4-6 hours every day or given artificial light for 8-1 hours.

3, temperature requirements

LYSIMACHIA christinae likes warm and humid environment, but it is not cold-resistant. It grows well in the temperature environment of 1-25℃. When the temperature rises above 32℃ in summer, it will stop growing, and the temperature in winter shall not be lower than 5℃.

4, reasonable watering

If you are hydroponic, you must change the water once a week and add special nutrient solution for foliage plants. If you use soil culture, you must keep water for a long time. Water should be poured once a day in the morning, and the water should not be too full. Take the water flowing out of the bottom hole as the degree to ensure that the basin soil is soaked.

In summer, the plants should be sprayed with water frequently to maintain high air humidity, and the leaves should be kept clean to facilitate photosynthesis. In winter, it is advisable to dry the soil in the basin. Watering should follow the principle of wet rather than dry, and avoid water accumulation, otherwise it will easily rot the roots.

5, scientific fertilization

LYSIMACHIA christinae is a foliage plant. The fertilizer is mainly nitrogen fertilizer, and potassium fertilizer should be supplemented appropriately, which is beneficial to root absorption and improves lodging resistance. In the vigorous growth stage, the copper grass is topdressing once every 2-3 weeks. If planted in potted plants or containers, a small amount of fertilizer should be applied.

6. Precautions

Generally, LYSIMACHIA christinae doesn't need to be pruned a lot. If the leaves are too dense, it is necessary to remove the withered bottom leaves, old leaves and diseased leaves in time to improve the lighting and ventilation conditions. In spring, when the pot is full of roots, change the pot and shape it by dividing plants. If the plant grows too high, it should be trimmed down to promote the germination of new branches at the base of stem and leaf.

In hot summer, everyone must remember to replenish water in time and add some fertilizers appropriately. For soil culture, you can bury some compound fertilizer in the soil, and for hydroponics, add nutrient solution. It is also very important to trim it regularly.

Origin and habitat of LYSIMACHIA christinae:

Hunan calls LYSIMACHIA christinae, paving lotus, Hubei calls it roadside yellow, Sichuan calls it a bunch of money, Beijing and Guangzhou call it Sichuan LYSIMACHIA christinae, Yunnan calls it real LYSIMACHIA, Guizhou calls it walking grass, Zhejiang and Jiangxi call it temporary rescue, and in Shaanxi it is nicknamed Cunguqi.

copperhead has white flowers in summer, and grows in the grass on the roadside or hillside, which is common in all parts of Chinese mainland. Stems are slender and take root at nodes. The leaves are round or kidney-shaped, with T-shaped hairs on the back, all around; Corolla bell-shaped yellow.

flowering period is April; The fruit period is July, and the capsule is nearly spherical. Sowing and branching propagation have strong spreading ability and are excellent ground cover plants. Shaped like copper coins and small lotus leaves.
