When to Plant Agastache Rugosa? Detailed Guide to Planting Time and Methods

Agastache rugosa (Korean mint) is generally planted in spring and autumn each year, with March-April and September-October being the most suitable. Sandy loam soil can be chosen, and the temperature should be kept at 18-25 degrees. Normally, nitrogen, phosphorus and potassium fertilizers are mainly used for application, and watering depends on the growth conditions.

Planting Time and Methods for Agastache rugosa

1. Temperature:

Generally, when planting Agastache rugosa, the annual average temperature should reach about 19-26 degrees. The temperature suitable for the growth of Agastache rugosa is 15-25 degrees, and at the seedling emergence stage, the temperature of the planting site should be kept between 20-25 degrees.

2. Water and fertilizer management:

When fertilizing, it should be combined with watering and intertillage, which helps the absorption of nutrients, while maintaining soil moisture and sustaining the water supply needed for the normal life of the plants. Finally, note that when there is a lot of rainfall, drainage should be done in time to prevent damage from waterlogging.

3. Plant density:

Generally, for spring sowing, the sowing rate per mu is usually 500 to 800 grams, while for autumn sowing, the sowing rate per mu is 500-600 grams. From the above sowing rates, 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 25-30 cm, while the row spacing for autumn sowing is generally between 30-35 cm.
