When to plant Yang He? When is the best time to plant Yang He?

1. Yanghe is suitable for planting in spring and autumn every year. Planting in spring is from March to April, and planting in autumn is in October.

2. To plant Yang He, you can choose sandy land with high terrain that is not prone to water accumulation, or flat fields. Dig the soil to make a furrow. After digging a trench of 30 cm, bury 5 cm of soil and mix it with a layer of decomposed fertilizer. Then put the seeds in, bury them in soil and pour enough water to fix them.

3. The spacing between sun lotus plantings is large and weeds are easy to grow. Weeds need to be cleaned up in time during the middle growth period. If there are not many weeds, they can be pulled out during watering. After Yanghe ginger grows to its third year, the old roots of Yanghe can be removed through cultivating, and the underground rhizomes can be straightened out to help the growth of the stems.

4. Sunflowers mostly germinate in spring. In summer and autumn, you can use grass mud, garbage mud, etc. to cover them with a layer of soil to build up the soil. During the growth period, sun lotus needs to be fertilized three times a day. Apply decomposed organic fertilizer once when it has just sprouted. Topdressing is needed once when the leaves expand and enters the peak growth season. Urea fertilizer is applied once in June.

5. Sunflowers are prone to drought when planted in higher-lying fields, but because their underground rhizomes are not waterlogging-resistant, watering should not exceed the border surface. In rainy weather, the drainage system should be dredged in advance to ensure the drainage of accumulated water. The aroma of Yanghe itself has a very good insect repellent effect, and there is generally no insect pest problem.
