Cultivation methods and precautions of Lithospermum officinale

1. Soil

Lithospermum officinale has a strong adaptability to the soil environment. When choosing a planting site, it is best to choose a relatively high, relatively dry, deep sandy loam or clay soil.

2. Lighting

It likes to grow in places with plenty of sunlight. When planting, you should choose a good planting site with good light so that it can grow better. In addition, it is also very afraid of high temperatures, so after entering summer, it needs to be shielded from the sun.

3. Water

During the germination period of comfrey seeds, the soil moisture should be around 20%, otherwise it will lead to poor seed growth. During the later growth period, the moisture content in the soil should not exceed 40%. Especially when it rains, it is important to drain away excess water, as waterlogging in the soil will hinder its growth.

4. Fertilization

Before planting, it is necessary to apply fertilizer to improve the soil structure. When it is still a seedling, it is usually necessary to apply some nitrogen fertilizer, and a small amount of phosphorus fertilizer at the same time. The later fertilization is done with cake fertilizer, and the last time is to apply some phosphorus fertilizer. Fertilizer should be applied about three times a year.
