Thuja

Below, you’ll find key tips tailored to this species’ requirements. Whether you’re new to plant care or have plenty of experience, these guidelines are here to support you in keeping your green companion healthy and vibrant.

1. Planting:
   • Choose a location with full sun to partial shade and well-draining soil.
   • Dig a hole twice the width of the root ball and equal in depth.
   • Place the plant in the hole, backfill with soil, and water thoroughly.
   • Ensure adequate spacing from other plants and structures to accommodate its mature height and spread.
2. Watering:
   • Water regularly during the establishment period to support healthy root development.
   • Once established, Thuja requires moderate watering; allow the soil to dry slightly between waterings.
   • Increase watering during prolonged dry periods or hot weather to keep the soil from becoming too dry.
3. Pruning:
   • Prune to maintain shape and density, especially if used as a hedge or screen.
   • Light pruning can be done throughout the growing season, while major pruning should be done in late winter or early spring before new growth begins.
   • Avoid heavy pruning into old wood, as it may not regrow effectively.
4. Fertilizing:
   • Feed with a balanced, slow-release fertilizer in early spring to support healthy growth.
   • Use fertilizers formulated for evergreen trees to provide essential nutrients.
   • Avoid over-fertilizing, as excessive nutrients can lead to excessive growth and potential issues.
5. Pest and Disease Control:
   • Thuja is relatively pest-resistant but can occasionally suffer from pests such as spider mites, bagworms, or scale insects; treat with appropriate insecticides if necessary.
   • Monitor for diseases such as fungal infections, root rot, or rust; ensure good air circulation and avoid waterlogged soil.
   • Regularly inspect the plant for signs of pests or disease and address issues promptly.
