Planting Instructions:

Planting

Plant the seeds in well-draining soil, ideally a mixture of potting soil and seed starting mix. Fill small pots or seed trays with this mixture, and gently press the seeds into the soil at a depth of about 1/8 inch (3 mm). Cover them lightly with soil, ensuring they are not buried too deep, as light aids in germination. Place the pots or trays in a location that receives indirect sunlight and maintain a consistent temperature between 20°C and 25°C (68°F to 77°F). Water the soil lightly to keep it moist but not waterlogged, as too much moisture can cause the seeds to rot.

Germination and Care

Germination can take 1-3 weeks, so patience is key. Keep the soil consistently moist, and provide indirect sunlight or use a grow light if needed. Once the seedlings emerge, continue to care for them by ensuring they receive adequate sunlight and water. As they grow stronger, gradually acclimate them to outdoor conditions by placing them outside for a few hours each day, increasing their exposure over time.

Transplanting

When the seedlings have grown to about 4-6 inches tall and have developed a strong root system, they can be transplanted into larger pots or directly into the ground. Choose a location that receives full to partial sunlight and has well-draining soil. Space the young trees appropriately, as Oriental Arborvitae can grow tall and wide. After transplanting, water them thoroughly and continue to monitor their growth, especially during the first few years when they are establishing themselves.
