Moderate climate (e. g. B. Germany, Switzerland, Poland)
Direct sowing from May to June is recommended. The plants should ideally be in a sunny location.

 General recommendations 
Direct sowing is recommended. After germination, thin out the plants to the specified plant spacing.
Green Shiso ideally prefers a soil that is moist, permeable and moderately nutrient-rich, with humus and loam. It does not tolerate waterlogging.

 Additional tips 
The aromatic substances in the leaves reduce once the flowers form. In order to quickly obtain a fine, crumbly and permeable soil with good nutrient and water retention capacity, it is recommended to additionally incorporate biochar and primary rock flour.

 Type of propagation 
Propagation occurs via seeds.

 Plant care 
Regularly removing the shoot tips promotes bushy growth. Evenly moist soil is necessary for stable growth. In severe dry periods, additional watering is recommended. No fertilization necessary.
