Start with a simple sowing in spring for your first Hemlock experience.
Seeds, small pots or direct garden space, potting soil.
Plant seeds in late winter to early spring for outdoor sowing.
Use a well-draining potting mix with a pH of 6.5–7. Ensure containers are at least 30 cm deep.
Sow seeds 1-2 cm deep, spacing them about 30 cm apart in rows 60 cm apart. Transplant seedlings when they have two sets of true leaves.
Keep soil consistently moist and provide partial shade to prevent leaf burn.
Water regularly, especially during dry spells. Fertilize lightly with a balanced organic fertilizer in early spring.
Prune back after flowering to encourage new growth and maintain shape.
Overwatering, planting too deep, neglecting shade during hot weather.
