Planting Cedar Trees to Form a Hedge: A Guide to a Beautiful, Functional Landscape

Cedar trees are a popular choice for creating natural hedges due to their evergreen foliage, fast growth, and ability to provide year-round privacy. Whether you want to enhance your property’s aesthetics or establish a natural barrier, planting cedar trees as a hedge is an excellent solution. This article will guide you through the process of planting, maintaining, and optimizing your cedar hedge for long-lasting beauty and functionality.

Why Choose Cedar Trees for a Hedge?

Cedar trees offer numerous benefits when planted as a hedge:

  • Privacy and Security: Dense foliage forms a natural screen, blocking views and noise.
  • Year-Round Greenery: Cedars are evergreens, keeping your landscape vibrant even in winter.
  • Low Maintenance: Once established, cedar hedges require minimal upkeep.
  • Windbreak and Erosion Control: Cedar hedges act as wind barriers and stabilize soil.
  • Wildlife Habitat: Birds and pollinators are attracted to cedar hedges, enhancing biodiversity.

Best Cedar Tree Varieties for Hedges

Choosing the right cedar tree variety is crucial for a successful hedge:

  1. Eastern White Cedar (Thuja occidentalis):

    • Ideal for cold climates.
    • Grows quickly and is easily shaped.

  2. Green Giant Cedar Cedar (Thuja plicata):

    • Known for its rich, green colour
    • Suitable for larger hedges.

  3. Emerald Cedar 

    • Best for warmer climates.
    • Adds a unique, dense texture

How to Plant Cedar Trees to Form a Hedge

1. Plan the Layout

  • Spacing: Place cedar trees 2–4 feet apart, depending on the variety and desired density.
  • Location: Choose a site with well-drained soil and plenty of sunlight.

2. Prepare the Soil

  • Test the soil pH; cedars prefer slightly acidic to neutral soil (pH 6.0–7.5).
  • Enrich the soil with compost or organic matter for optimal growth.

3. Planting the Trees

  • Dig a hole twice as wide and as deep as the root ball.
  • Place the tree in the hole, ensuring the root flare is level with the ground.
  • Backfill with soil and tamp down gently to eliminate air pockets.

4. Watering and Mulching

  • Water thoroughly after planting and maintain consistent moisture, especially in the first year.
  • Apply a 2–3 inch layer of mulch around the base to retain moisture and regulate soil temperature.

Caring for Your Cedar Hedge

1. Watering

  • Newly planted cedar trees need regular watering, especially during dry periods.
  • Mature hedges are drought-tolerant but benefit from occasional deep watering.

2. Pruning

  • Prune annually to maintain shape and encourage dense growth.
  • Avoid cutting into the old wood, as cedars may not regrow from it.

3. Fertilizing

  • Use a slow-release, balanced fertilizer in early spring to promote healthy growth.
  • Avoid over-fertilizing, which can lead to weak, leggy growth.

4. Pest and Disease Control

  • Watch for cedar pests like spider mites and bagworms.
  • Ensure proper spacing for airflow to reduce the risk of fungal diseases.

Design Ideas for Cedar Hedges

  • Privacy Screen: Plant a row of cedars along property lines to create a natural privacy wall.
  • Windbreak: Use cedar hedges to shield your home or garden from strong winds.
  • Formal Landscape: Shape your cedar hedge into geometric designs for a manicured look.
  • Wildlife Corridor: Allow the hedge to grow naturally to provide habitat for birds and small animals.

  1. How long does it take for cedar trees to form a hedge?

    • Cedar trees can take 3–5 years to form a dense hedge, depending on the variety and growing conditions.

  2. Can I plant cedar trees in the fall?

    • Yes, fall is an excellent time to plant cedars, as the roots can establish before winter.

  3. How tall do cedar hedges grow?

    • Most cedar varieties can grow 10–50 feet tall, but regular pruning keeps them at the desired height.

  4. Are cedar hedges deer-resistant?
