The growing environment and local conditions of Salvia miltiorrhiza

Salvia miltiorrhiza growth environment and conditions

Salvia miltiorrhiza is distributed throughout China. It generally grows in grass on sunny hillsides, beside ditches, on roadsides or on forest edges. It prefers a growing environment with sufficient sunlight and warmth.

Salvia miltiorrhiza growth conditions

Salvia miltiorrhiza prefers a warm, well-lit environment with an average annual temperature of 17.1 degrees and an average air humidity of around 77%, and it grows and develops well. If there is insufficient light and low temperatures during the growing period, the plant will grow poorly. It is suitable for planting in moist, fertile sandy loam, and can grow in neutral, slightly acidic, and slightly alkaline soils.

Salvia miltiorrhiza growth temperature

The most suitable growth temperature for the aboveground part of Salvia miltiorrhiza is between 20-26 degrees. When the average temperature is below 10 degrees, the aboveground part begins to wither. It is relatively frost-resistant. The leaves remain green after the first frost. The roots can safely overwinter at around minus 15 degrees. The suitable temperature for seed germination is between 18-22 degrees. Maintain a certain humidity and seedlings will emerge in about two weeks.

Growth process of salvia miltiorrhiza

Salvia miltiorrhiza is a perennial herb with a peak growth season for stems and leaves from March to May. The branches and leaves are lush from April to June, and it blooms and bears fruit one after another. The roots grow rapidly after July, and the root system accelerates branching and swelling in mid-to-late August. At this time, water accumulation and root rot should be prevented. From the end of October to early November, the above-ground part begins to wither.

Salvia miltiorrhiza planting time and method

Salvia miltiorrhiza is suitable for planting in late autumn, early winter and mid-to-late March in spring. Its reproduction methods include seed reproduction, root division and cutting reproduction. If it is propagated by seeds, it is necessary to germinate in advance, which can promote seed germination and enhance the resistance of the plant.

For root division propagation, you need to select roots with good growth for planting. For example, those with thick tubers and no diseases or pests are of high quality. For cutting propagation, you need to choose well-grown stems of Salvia miltiorrhiza and cut them into small sections for cuttings. Several leaves must be left on each section, so that the survival rate will be much higher.
