Tall, thin evergreen trees, also known as columnar or fastigiate trees, are ideal for creating privacy screens, windbreaks, or vertical accents in landscapes with limited space. Popular varieties include Italian Cypress, Skyrocket Juniper, and Emerald Green Arborvitae. These trees typically require full sun, well-draining soil, and moderate watering.
As a landscape architect with over two decades of experience, I’m excited to share my knowledge about these elegant, space-efficient trees. Whether you’re looking to enhance your property’s privacy or add a striking vertical element to your garden, tall, thin evergreens offer versatile solutions for various landscaping needs.

Planting and Care Tips
Choosing the Right Location
- Ensure full sun exposure (6+ hours of direct sunlight daily)
- Consider mature height and spread when planting near structures
- Allow for adequate spacing between trees if creating a screen
Soil Preparation
- Most tall, thin evergreens prefer well-draining soil
- Amend heavy clay soils with organic matter to improve drainage
- Conduct a soil test to determine pH and nutrient levels

Planting Process
- Dig a hole twice as wide as the root ball and equally deep
- Place the tree at the same depth it was in the container
- Backfill with native soil, tamping gently to remove air pockets
- Water thoroughly after planting
Watering
- Water deeply and regularly during the first growing season
- Once established, most species are drought-tolerant but benefit from occasional deep watering during dry spells
Fertilizing
- Apply a slow-release, balanced fertilizer in early spring
- Avoid over-fertilizing, which can lead to excessive growth and weak structure
Pruning
- Most tall, thin evergreens require minimal pruning
- Remove dead or damaged branches as needed
- Light shaping can be done in late winter or early spring
