How to grow Salvia miltiorrhiza for high yield

1. Planting time

There are many ways to plant Salvia miltiorrhiza. You can choose to plant root segments. This planting method is very commonly used and can help it survive after planting. The planting time is generally around March of the lunar calendar. The temperature at this time is relatively stable and the climate is suitable for growth, which is conducive to the survival of Salvia miltiorrhiza.

2. Planting soil

First determine the planting location. You can choose a sunny and sheltered place with good ventilation. Choose well-drained, breathable, fertile, slightly acidic or slightly alkaline land for planting. Deeply plow and tidy up the soil, and cover the soil with decomposed organic fertilizer.

3. Field management

Salvia miltiorrhiza likes fertilizer and needs to be fertilized several times during the growth period. The first time is to apply fertilizer to promote seedling growth when the plant turns green again. The second time is from mid-April to late May. The third time is to apply fertilizer to grow roots after pruning the old stems in June and July. The amount of fertilizer can be increased. It is better to apply fertilizer in ditches or holes for the second and third times.

4. Do a good job of irrigation and drainage

During the entire growth period of the Salvia miltiorrhiza plant, attention should be paid to drainage to prevent it from being waterlogged in the rainy season. Digging and ditching can be combined with fertilization, and the soil should be covered after fertilization. Watering should be done in time during the dog days and in continuous autumn drought, preferably in the morning and evening.
