Soil: Moist, well-drained soil is essential. Enrich the soil with compost or organic matter to improve structure and maintain consistent moisture.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth to allow room for root development.
Soil Preparation: Mix in compost or well-rotted organic matter to enhance fertility and drainage.
Planting: Position the plant so the root ball sits level with the surrounding soil, then backfill and firm gently.
Watering After Planting: Water thoroughly to settle the soil and help Cryptomeria establish quickly.

Light Trimming: Your Cryptomeria may be lightly trimmed in late winter to shape or tidy the plant.
Maintenance: Remove any dead or damaged growth to keep the plant healthy and attractive.
Mulching
