Where is the best place to plant Adenophora

Planting place of Adenophora

Generally, Adenophora grows in low mountain grasses and rock cracks, and also grows in grasslands at high altitudes. It likes a cool climate and is best cultivated in sandy loam with deep, fertile soil, rich in humus and good drainage.

Adenophora is suitable for planting in oil sand land or sandy loam that is well-drained and fertile. It is not suitable for planting in low-lying, waterlogged areas with heavy soil. There are two places in China known as the hometown of Adenophora, namely Inner Mongolia and Shandong.

Planting conditions of Adenophora

Whether it is cultivated or wild, Adenophora radix is ​​mostly distributed between 400-800 meters above sea level. It likes to grow in warmer areas and is slightly cold-resistant, but not high-temperature resistant. If it encounters high temperature and humidity, it is prone to disease, especially in the seedling stage, and is more afraid of strong sunlight.

Adenophora requires an average annual temperature of about 16°C, an annual rainfall of about 900 mm, an average relative humidity of about 79%, 1,200 hours of sunshine throughout the year, and a frost-free period of about 330 days.

Key points of planting and management of Adenophora

1. Land preparation

Adenophora is a deep-rooted crop, so the land must be plowed more than 70 centimeters deep, and the soil must be broken up thoroughly, and the grass roots and stone debris must be picked up. It doesn't matter if the land where Adenophora is planted is a little dry, but if it is too waterlogged, the roots of the Adenophora will rot completely, resulting in nothing. Therefore, ditches must be dug around the land to ensure smooth drainage.

2. Planting

The sowing period of Adenophora radix is ​​generally from the beginning of winter to the first snow, when the land has not yet frozen, but there is also sowing during the Spring Festival, because winter sowing can produce more uniform seedlings, grow more vigorously, and have stronger drought resistance than spring sowing. However, winter sowing should not be too early to avoid early emergence of seedlings and easy frost damage.

3. Disease prevention and control

After the beginning of autumn, the diseased plants first develop reddish-brown spots on the old stems and leaves. Later, the surface of the spots breaks. At this time, emergency prevention and control is needed. After harvest, the garden must be cleared and the remaining stems and dead leaves dealt with.
