Gardening in coastal regions comes with its own set of challenges. The salty air, sandy soils, rising sea levels, and strong winds can make it hard to find plants that thrive. However, if you’re looking for evergreens that add resilience and aesthetic appeal to your garden, Thuja trees are an excellent choice. With salt-tolerant varieties and proper care, coastal Thuja trees can completely overhaul your garden, turning it into a lush, green oasis.
Why Choose Thuja for Coastal Gardens?
Thuja trees are hardy evergreens known for their dense foliage and adaptability. Coastal Thuja trees are particularly beneficial for gardeners near the sea because they tolerate moderate salt exposure and windy conditions. Their ability to maintain lush greenery year-round makes them a favorite for privacy hedges, windbreaks, and ornamental features.
Thuja trees also contribute to environmental health by improving air quality, stabilizing sandy soils, and providing shelter for wildlife. For coastal gardens, they are a practical and attractive solution.
Top Salt-Tolerant Thuja Varieties
When choosing coastal Thuja trees, it’s essential to pick varieties that can withstand salt spray and sandy soil. Here are some options to consider:
1. Green Giant Thuja
Known for its rapid growth and durable nature, the Green Giant is a great choice for coastal areas. It forms a dense, tall hedge that provides excellent privacy and protection against winds.
In gardens or residential settings, Green Giant Thuja grows to 20–30 feet due to pruning and limited space. However, in areas with optimal water availability, high soil quality, and ample space, it can reach 50–60 feet. This is especially true when left unpruned and grown in favorable climates.
- Height:Up to 50–60 feet (in unrestricted and ideal growth conditions)
- Width:12–20 feet
- Best Use:Privacy screens, windbreaks
2. Emerald Green Thuja
This compact variety is perfect for smaller coastal gardens. It offers year-round greenery and requires minimal maintenance.
- Height:Up to 12–15 feet
- Width:3–4 feet
- Best Use:Decorative borders, small hedges
3. American Pillar Thuja
Ideal for narrow spaces, the American Pillar grows tall and slim, making it a practical choice for modern coastal landscapes.
- Height:Up to 30 feet
- Width:4–5 feet
- Best Use:Tall hedges, space-saving screens
Steps to Plant Thuja Trees in Coastal Soil
Proper planting is key to helping your Thuja trees thrive in coastal conditions. Follow these steps for success:
1. Choose the Right Location
Thuja trees thrive in full sun, so pick a spot with at least 6 hours of direct sunlight daily. Avoid areas with poor drainage, as Thujas don’t tolerate waterlogged soil.
2. Prepare the Soil
Coastal soil is often sandy and low in nutrients. Improve the soil by mixing in compost or organic matter to boost water retention and fertility.
3. Dig the Hole
Dig a planting hole that is twice as wide and the same depth as the root ball to allow for root expansion and establishment.
4. Plant the Tree
Plant the Thuja tree so the top of the root ball is even with the ground. Fill in the hole with soil and gently pat it down to expel air.
5. Water Thoroughly
Water deeply after planting to help the soil settle and ensure the roots are hydrated.
6. Mulch for Protection
Cover the base of the tree with 2-3 inches of mulch to retain moisture, regulate soil temperature, and reduce weed growth. Keep the mulch a few inches away from the trunk to prevent rot.
Steps to Care for Coastal Thuja Trees
Caring for Thuja trees in coastal regions involves regular watering, occasional feeding, and protection from harsh conditions.
1. Watering
Salt spray and sandy soils can dry out Thuja trees quickly. Water deeply once or twice a week, especially during the first year of growth. Mature trees need less frequent watering but should still be hydrated during dry spells.
2. Fertilizing
Use a slow-release fertilizer designed for evergreens in early spring. This supports healthy growth and helps the tree resist salt stress. Avoid over-fertilizing, as excess nutrients can harm the plant.
3. Pruning
Prune annually to remove dead or damaged branches and maintain the tree’s shape. Avoid cutting into the inner brown growth, as it will not regrow.
4. Protecting Against Salt Spray
While salt-tolerant, Thuja trees can still suffer from excessive salt exposure. Rinse off salt deposits from the foliage after storms or periods of heavy wind.
Benefits of Coastal Thuja Trees
Planting Thuja trees in coastal gardens offers many benefits that transcend mere aesthetics:
- Privacy:Their dense foliage offers privacy, shielding the area from outside eyes by blocking their view.
- Windbreak:Thuja trees help block strong coastal winds, creating a more comfortable outdoor space.
- Erosion Control:The roots help to anchor and stabilize the plant in sandy soil, which prevents erosion caused by wind and water.
- Wildlife Habitat:Birds and small animals often seek shelter in Thuja hedges, contributing to local biodiversity.

Common Mistakes to Avoid When Planting Thuja Trees
To give your coastal Thuja trees the best chance to thrive, avoid these pitfalls:
- Overwatering:While they need consistent moisture, excessive watering can result in root rot.
- Planting Too Far Down:To avoid stem rot, the root crown should always be positioned above the soil surface.
- Ignoring Salt Rinse:Salt buildup on foliage can damage the plant if not rinsed away.
