Why Choose Fast Growing Tall Narrow Trees? The Surprising Benefits
When you think of a “fast-growing” tree, you might picture a weedy, weak-wooded specimen. But modern horticulture has given us incredible columnar varieties that are both sturdy and speedy. Opting for these vertical wonders brings a host of advantages to your garden, making them one of the smartest planting choices for modern landscapes.
Here are some of the best benefits of fast growing tall narrow trees:
- Instant Privacy Screen: This is the number one reason many gardeners seek them out. Planted in a row, they create a dense, living wall much faster than a traditional hedge, shielding you from nosy neighbors or an unsightly view.
- Architectural Interest: Their strong vertical lines draw the eye upward, making a small space feel larger. They can be used to frame an entryway, soften the corner of a house, or add a formal, elegant touch to your garden design.
- Perfect for Tight Spaces: Have a narrow side yard, a small urban garden, or a thin planting strip? These trees are the perfect solution, providing height and impact without the wide, space-hogging canopy.
- Effective Windbreaks and Sound Barriers: A dense row of columnar evergreens can significantly reduce wind and muffle traffic noise, creating a more peaceful and protected backyard oasis.
- Eco-Friendly Impact: Like all trees, they improve air quality, reduce erosion, and provide shelter for birds. Choosing native varieties offers even more support for local wildlife, making them a great choice for eco-friendly fast growing tall narrow trees.

Your Step-by-Step Fast Growing Tall Narrow Trees Guide to Planting Success
You’ve picked your tree—hooray! Now comes the most important part: giving it a great start in life. Proper planting is the single most crucial factor in a tree’s long-term health and growth speed. This section is your go-to on how to fast growing tall narrow trees from day one.
- Right Tree, Right Place: Before you even dig, double-check your tree’s tag. Confirm its mature width and height, and ensure your chosen spot gets the right amount of sunlight. Don’t plant a 60-foot giant under a power line!
- Timing is Everything: The best times to plant are in the spring or fall. This allows the roots to get established in mild temperatures before the stress of summer heat or deep winter cold.
- Dig the Perfect Hole: Here’s the golden rule: dig the hole two to three times wider than the root ball, but only just as deep as the root ball. Planting a tree too deep is a common and fatal mistake.
- Prepare the Tree: Gently remove the tree from its container. If the roots are tightly wound in a circle (root-bound), use your fingers or a small knife to gently tease them apart. This encourages them to grow outward into the soil.
- Plant and Backfill: Place the tree in the center of the hole. The spot where the trunk widens to meet the roots (the “root flare”) should be slightly above ground level. Backfill the hole with the native soil you removed, breaking up any large clumps.
- Water, Water, Water: Immediately after planting, give your new tree a deep, slow soaking. Let the water trickle from a hose for 10-15 minutes to ensure the entire root zone is saturated and any air pockets are settled.
- Add a Layer of Mulch: Apply a 2-3 inch layer of organic mulch (like shredded bark or wood chips) around the base of the tree, but don’t let it touch the trunk! This “donut” of mulch will conserve moisture, suppress weeds, and regulate soil temperature.
The Ultimate Fast Growing Tall Narrow Trees Care Guide
Once your tree is in the ground, a little consistent care will make all the difference in its growth rate and overall health. Don’t worry—these are simple steps! This is your essential fast growing tall narrow trees care guide.
Watering Wisely
For the first year, your tree is thirsty! Check the soil every few days. If the top 2-3 inches are dry, it’s time for another deep, slow watering. It’s much better to water deeply once a week than to sprinkle a little every day. This encourages deep, strong root growth.
Feeding Your Giants
Most fast-growing trees appreciate a little boost. In early spring, apply a balanced, slow-release fertilizer formulated for trees and shrubs. Follow the package directions carefully—more is not better!
Pruning for Shape and Health
One of the best things about columnar trees is that they require very little pruning to keep their shape. Your main job is to simply remove any dead, damaged, or crossing branches with a clean, sharp pair of pruners. The best time to do this is in late winter or early spring before new growth appears.
Avoiding Common Problems with Fast Growing Tall Narrow Trees
Even with the best care, you might run into a few bumps. Knowing what to look for is half the battle. Here are some solutions to the most common problems with fast growing tall narrow trees.
Problem: Weak Growth or Leaning
This is often a sign the tree was planted too deep, or the soil is too compacted. Unfortunately, this is hard to fix later. It highlights why following proper planting steps from the start is one of the most important fast growing tall narrow trees best practices.
Problem: Browning Needles on Evergreens
Don’t panic! This is usually caused by one of two things: transplant shock (it’s stressed from the move) or underwatering. Ensure you’re providing consistent, deep waterings, especially during its first year and during hot, dry spells.
Problem: Pests and Disease
A healthy tree is the best defense! Pests like bagworms or spider mites are more likely to attack a stressed tree. Proper watering and feeding will make your tree much more resilient. If you do spot an issue, identify the pest and use the most targeted, eco-friendly treatment available.
Frequently Asked Questions About Fast Growing Tall Narrow Trees
How far apart should I plant fast growing tall narrow trees for a privacy screen?
A great rule of thumb is to space them about half of their mature width apart. For example, if a Taylor Juniper gets 4 feet wide, plant them 2 feet apart (center to center) for a quick, dense screen. For Thuja Green Giants that get 15 feet wide, planting them 7-8 feet apart is ideal.
What is the absolute fastest growing narrow tree?
The Lombardy Poplar is likely the fastest, often growing over 6 feet a year. However, it comes with significant drawbacks like a short lifespan and aggressive roots. For a fast but more reliable and longer-lived option, the Thuja ‘Green Giant’ is the top contender.
Can I grow these trees in large containers?
Some of them, yes! Smaller varieties like the Sky Pencil Holly or North Pole® Arborvitae do wonderfully in large pots on a patio or balcony. Just be sure the container has excellent drainage and be prepared to water more frequently, as pots dry out quickly.
Are there any eco-friendly fast growing tall narrow trees that support wildlife?
Absolutely! Choosing native varieties is a fantastic way to support your local ecosystem. The Taylor Juniper (a cultivar of the native Eastern Redcedar) provides berries for birds. Columnar oaks provide acorns and are host plants for hundreds of species of pollinators.
Your Vertical Oasis Awaits
There you have it—your complete roadmap to creating the garden of your dreams with the help of these amazing vertical trees. From providing a lush privacy screen in just a few seasons to adding an elegant architectural touch, fast growing tall narrow trees are a game-changer for any landscape.
