Self-Heal

How to Grow: Self-Heal (Prunella vulgaris)

Self-Heal is easily grown from seed and readily establishes itself.

Direct Sowing (Recommended): Sow seeds directly outdoors in early spring after the last frost, or in late fall for germination the following spring. It often prefers to establish in disturbed areas or bare soil.
Sowing Depth: Scatter seeds lightly on the surface of prepared soil and gently press them down, or lightly cover with about 1/8 inch of soil. Light can aid germination.
Germination Time: Seeds typically germinate in 14-21 days at temperatures around 60-70°F (15-21°C). Keep the soil consistently moist during this period. Cold stratification (exposing seeds to cold, moist conditions for 2-4 weeks) can improve germination rates, mimicking its natural outdoor cycle.
Starting Indoors: Start seeds indoors 6-8 weeks before the last frost for earlier blooms. Transplant outdoors after all danger of frost has passed.
Division: Established clumps can be divided in spring or fall, which is an easy way to propagate it.

Light & Growing Self-Heal is adaptable to a range of light conditions.

Sunlight: Thrives in full sun (6+ hours direct sunlight) to partial shade (4-6 hours), and can even tolerate fairly deep shade, though flowering will be reduced. Its versatility makes it great for many garden spots.
Growth Habit: It forms a low-growing, spreading mat or rosette, typically 6-18 inches tall, sending out creeping stems (stolons) that root where they touch the ground. It produces distinctive square-stemmed flower spikes topped with dense clusters of small, purplish-blue (sometimes pink or white) tubular flowers.
Maintenance: o Containment/Management: While not as aggressive as some mints, it can spread over time. If you want to limit its spread, occasional weeding or mowing can help. o Mowing (if in lawn): It tolerates mowing well and will continue to grow and flower, even when cut short, making it an excellent component of a 'no-mow' or low-maintenance lawn. o Deadheading (Optional): Removing spent flower stalks can encourage more blooms or prevent excessive self-seeding if desired.

Harvesting Self-Heal The entire aerial portion of the plant (leaves and flowers) is typically harvested for medicinal use.

Timing: The best time to harvest Self-Heal is when the plant is in full bloom, usually from late spring through summer, as this is when its medicinal compounds are believed to be most potent.
How to Harvest: o Cut Whole Plant: Use clean scissors or a sharp knife to cut entire stems just above the ground. o Regular Harvesting: Regular harvesting helps keep the plant tidy and encourages fresh growth.
Storage: o Fresh: Fresh leaves and flowers can be used in tinctures or poultices. o Drying: Self-Heal dries well. Hang small bunches upside down in a cool, dark, well-ventilated area, or spread chopped plant material in a single layer on screens. Once thoroughly dry, store in airtight glass jars away from light and heat. It's often dried to make teas or tinctures.
