- Soil requirements: Self heal (Prunella vulgaris) prefers well-drained soil with a pH level between 5.5 and 7.5. It can tolerate a variety of soil types, including sandy, loamy, and clay soils.
- Sunlight needs: Self heal thrives in full sun to partial shade. It can adapt to different light conditions but performs best with at least 4-6 hours of sunlight per day.
- Watering requirements: Self heal requires moderate watering. Keep the soil consistently moist but not waterlogged. Water the plants regularly, especially during dry periods, to ensure healthy growth.
- Planting season: The best time to plant self heal seeds is in the spring or fall. These seasons provide optimal conditions for germination and growth.
- Depth and spacing: Plant self heal seeds at a depth of 1/8 inch (3 mm) and space them about 12 inches (30 cm) apart to allow for adequate growth and air circulation.
- Germination time: Self heal seeds typically germinate within 14 to 21 days under optimal conditions. Ensure the soil remains moist during the germination period.
- Maturity time: Self heal plants usually reach maturity within 60 to 90 days after planting. The exact time may vary depending on growing conditions.
- Harvesting time: The best time to harvest self heal is in the early morning when the essential oils are most concentrated. This is typically when the flowers are in full bloom.
- Harvesting tips: Use sharp scissors or pruning shears to cut the stems just above a leaf node. Harvesting regularly encourages new growth. Store the harvested parts in a cool, dry place or use them fresh for medicinal purposes.
