Plant guide

Planting & care

Planting Thuja Green Giant

  • Select a location with full sun to partial shade and well-draining soil.
  • Space the plants 5 to 6 feet apart for a hedge or screen.
  • Dig a hole twice as wide and as deep as the root ball.
  • Remove the plant from its container and gently loosen the roots.
  • Place the plant in the hole, ensuring it's at the same depth as it was in the pot.
  • Backfill the hole with soil, tamping down to remove air pockets.
  • Water thoroughly after planting to settle the soil.
  • Mulch around the base to retain moisture and prevent weeds.

Care and Maintenance

  • Water regularly during the first growing season to establish a deep root system.
  • Apply a balanced, slow-release fertilizer in early spring.
  • Prune in late winter or early spring to shape and remove any dead or damaged branches.
  • Monitor for pests and diseases, treating as necessary.

Remember, Thuja Green Giants are low-maintenance once established, but consistent watering and annual fertilization will help ensure healthy growth. Happy gardening!

FAQ

Common questions

FAQs for the Thuja Green Giant

1. How do I plant Thuja Green Giant?

  1. Choose the right spot: Select a location with full to partial sunlight and well-draining soil.
  2. Soil preparation: Mix compost or aged manure into your planting site to enrich the soil.
  3. Spacing: Space your Thuja Green Giants 5-6 feet apart for a hedge, or 10-12 feet apart for individual trees.
  4. Planting: Dig a hole as deep and twice as wide as the root ball. Remove the plant from its container, gently loosen the roots, and place it in the hole. Fill the hole with soil and water thoroughly.
  5. Watering: Keep the soil consistently moist until the plant is established.

2. How should I water my Thuja Green Giant?

  • Initial watering: Water deeply after planting to settle the soil around the roots.
  • Ongoing care: Water your Thuja 1-2 times per week, more frequently in hot, dry conditions. Reduce watering in cooler months.
  • Monitoring: Check the soil moisture regularly; it should be moist but not waterlogged.

3. What is the best fertilizer for Thuja Green Giant and how often should I apply it?

Fertilization: Use a balanced, slow-release fertilizer formulated for evergreens in early spring, just before new growth begins. If growth is slow or foliage color is off, a second application in mid-summer can be beneficial. Avoid fertilizing late in the season to prevent new growth from being damaged by frost.

4. How do I ensure proper pollination of my Thuja Green Giant?

Pollination: Thuja Green Giant is a sterile hybrid and does not produce viable seeds, so pollination is not a concern for this plant. Instead, focus on providing optimal growing conditions to ensure healthy growth.

5. When and how should I harvest Thuja Green Giant?

Harvesting: Thuja Green Giant is primarily grown for ornamental purposes, so "harvesting" typically refers to pruning. Prune in late winter or early spring before new growth starts. For shaping or size control, light pruning can also be done in summer. Always use clean, sharp tools and make cuts just above a leaf node or branch junction.
