Prunus serotina subsp serotina (Black Cherry)

Seed Treatment: Prunus serotina seeds have deep dormancy and require both warm and cold stratification for successful germination: <ol> <li aria-level="1">Warm Stratification: • Place seeds in moist sand or vermiculite • Store at 68–77°F (20–25°C) for 60–90 days • Keep the medium consistently moist </li> <li aria-level="1">Cold Stratification: • After warm strat, transfer seeds to 35–41°F (2–5°C) for 90–120 days • Use a sealed plastic bag or container to retain moisture • Label with date and check periodically for mold or early sprouting</li> </ol> When to Sow: • Outdoors: Sow in fall to allow for natural stratification over winter • Indoors: Sow in spring after completing both stratification periods Sowing Instructions: • Sow seeds ½ inch (1.25 cm) deep in a deep container or directly in the ground • Use a moist, well-draining soil mix • Maintain moderate moisture, avoid waterlogging • Germination may take several weeks to months depending on dormancy break Light Requirements: • Prefers full sun but tolerates partial shade, especially when young Soil Requirements: • Adaptable to various soils but prefers moist, well-drained, fertile loam • Tolerates slightly acidic to neutral pH (5.5–7.0) Watering: • Keep soil evenly moist during germination • Once established, trees are drought-tolerant, but benefit from deep watering in dry periods Spacing & Growth: • Space trees 20–30 feet (6–9 meters) apart • Fast-growing; can reach 50–80 feet tall Growing Tips: • Produces white fragrant flower clusters in spring and edible dark berries in late summer • Berries attract birds, pollinators, and wildlife • Can be grown for timber, shade, wildlife habitat, or ornamental use • Avoid planting near sidewalks or patios — fruits can be messy • Hardy in USDA Zones 3–9
