What are the precautions for planting Agastache rugosa? A full breakdown of the latest cultivation key points
Agastache rugosa, also known as hexiang and mountain fennel, is a perennial herbaceous plant of the genus Agastache. It generally blooms between June and September and bears fruit between September and November. Because it is not strict about soil requirements, it is planted throughout our country, but the main planting areas are Sichuan, Hunan, Jiangsu, Guangzhou and Zhejiang, among others. So today, the editor will mainly introduce some precautions when planting Agastache rugosa. Let's take a look below.
1. Planting time
Agastache rugosa can be sown in two seasons, in spring and autumn. What we need to pay attention to is that the spring sowing time is generally around late March to early April, and the sowing time cannot be later than mid-April, while autumn sowing is from September to October. For spring sowing, we also need to pay attention that when sowing, shallow furrows should be opened for sowing, with holes about 1 cm deep, while for autumn sowing, the holes should be about 3 to 4 cm deep.
2. Growing temperature
Agastache rugosa has the characteristics of liking high temperatures and liking sunlight. Generally, the annual average temperature for planting Agastache rugosa should reach about 19 to 26 degrees. The temperature suitable for the growth of Agastache rugosa is 18 to 25 degrees, and at the seedling emergence stage, the temperature of the planting site should be kept between 20 and 25 degrees. The temperature during later growth cannot be lower than 16 degrees, and at the same time cannot be higher than 35 degrees, otherwise it will affect the growth rate and may even cause Agastache rugosa to stop growing.
3. Water and fertilizer management
Water and fertilizer management is a very important matter in the planting process. For fertilizing Agastache rugosa, complete fertilizer generally gives the best effect, that is, each fertilization should be complete, including nitrogen fertilizer, potassium fertilizer, phosphorus fertilizer, organic fertilizer, farmyard manure, etc., applied in a certain amount at a fixed time. Second, when fertilizing, it should be combined with watering and intertillage, which is conducive to the absorption of nutrients, while maintaining soil moisture and maintaining the water supply needed for the normal life of the plants. Finally, note that when there is more rainfall, drain water in time to prevent damage from flooding.
4. Plant density
Generally, for spring sowing, the sowing amount per mu is generally 500 to 800 grams, while for autumn sowing, the sowing amount per mu is 500 to 600 grams. From the sowing amounts above, it can be seen that the density of autumn sowing is greater than that of spring sowing. The row spacing for spring sowing is generally between 25 and 30 cm, while the row spacing for autumn sowing is generally between 30 and 35 cm.
5. Pests and diseases
Pests and diseases are something that requires great attention in the planting process. The main diseases of Agastache rugosa are fusarium wilt, angular leaf spot, brown spot and leaf spot. We can use carbendazim, Bordeaux mixture, metalaxyl mancozeb and ridomil to prevent and control them. The most harmful are red spiders, silver-striped leaf moths, leaf roller borers, cutworms, mole crickets, etc. Generally, acaricides and trichlorfon are used to kill them.
The above are some issues that need attention when planting Agastache rugosa, compiled by the editor based on the questions raised by everyone. In fact, as long as you are relatively careful during the planting process and plant according to the correct planting techniques, many problems will not arise.
