Detailed Explanation of Agastache rugosa Planting Techniques and Management Methods

1. Site selection, land preparation and fertilization: Choose well-drained sandy soil or loam soil, apply about 2500 kg of barnyard manure per mu, plow it into the ground, level it and make beds.

2. Propagation method: When harvesting Agastache rugosa in June to July, the inflorescences are just emerging or blooming, so a seed field should be reserved and not harvested; harvest when most of the seeds turn brown. After harvesting, place in a cool place to after-ripen for several days, dry in the sun and thresh the seeds.

3. Field management: When the temperature is in the range of 13-18°C and the soil has sufficient moisture, seedlings emerge in about 10 days. Thin the seedlings when they are 6-10 cm tall; for drilling, keep seedlings at a spacing of 10-15 cm. For hole sowing, keep 3-4 plants per hole, and loosen the soil and hoe weeds frequently. When the seedlings are 25-30 cm tall, earth up the soil, combined with fertilization; generally apply 2-3 times from June to August, mainly with human feces and urine or fully decomposed manure, each time applying about 1000 kg of dilute human and livestock manure water as appropriate, or apply 10-13 kg of ammonium sulfate per mu, and water after application.
