ByRimon Chowdhury Updated on

Have you ever walked through your garden, admired a beautiful, mature tree, and then looked down to see a network of thick roots snaking across the surface of the soil? It’s a common sight, and one that often leaves gardeners scratching their heads. Is this a problem? Is the tree unhealthy? And what on earth are you supposed to do about it?

If you’ve ever felt that mix of concern and confusion, you’re in the right place. The truth is, dealing with trees with exposed roots can feel intimidating, but it doesn’t have to be. I promise that by the end of this guide, you’ll not only understand why this happens but also feel confident in how to care for your tree and even transform that tricky area into a stunning garden feature.

We’re going to dig into the causes, learn how to spot potential issues, and walk through a complete trees with exposed roots care guide. We’ll also cover some fun, eco-friendly landscaping ideas that work with your tree, not against it. Let’s get started!

Why Do Trees Have Exposed Roots? Uncovering the Root of the Issue

First things first, let’s clear up a common misconception: exposed roots aren’t always a sign of a sick or dying tree. In many cases, it’s a perfectly natural occurrence. Understanding the cause is the first step in deciding the best course of action.

Soil Erosion and Compaction

This is the most common culprit. Over years, wind and rain naturally wash away the top layers of soil, gradually revealing the roots that were once just beneath the surface. It’s a slow process you might not even notice until the roots are quite prominent.

Soil compaction is another major factor. In high-traffic areas—like that path the kids always take across the lawn—the soil gets pressed down. Tree roots need oxygen to survive, and when the soil is compacted, they will often grow upwards toward the surface where they can breathe more easily.

Tree Species and Growth Habits

Some trees are simply genetically programmed to have shallow root systems. It’s just part of their nature! You’ll often see this with species like:

  • Silver Maples
  • Beeches
  • River Birches
  • Poplars
  • Willows

If you have one of these in your yard, seeing some surface roots is completely normal and expected. It’s just how they grow.

Shallow or Poor Soil Conditions

Trees are incredibly smart. Their roots will always grow where they can find what they need most: water, oxygen, and nutrients. Most of a tree’s vital feeder roots are located in the top 12-18 inches of soil.

If you have heavy clay soil that drains poorly or a thin layer of topsoil over rock, roots will stay near the surface. They’re simply avoiding the dense, oxygen-deprived soil below and seeking resources closer to the top. This is a classic example of a tree adapting to its environment.

Is It a Problem? How to Diagnose Common Problems with Trees with Exposed Roots

Okay, so we know that exposed roots can be normal. But when should you be concerned? This section covers the common problems with trees with exposed roots so you can tell the difference between a natural feature and a cry for help.

The Tripping Hazard

Let’s start with the most obvious issue: safety. Gnarled roots can be a serious tripping hazard, especially in play areas or along walkways. This is less about the tree’s health and more about making your garden safe for family and friends.

Damage from Mowers and Foot Traffic

This is where the real danger to your tree begins. Running a lawnmower over exposed roots can be disastrous. The mower blades can scalp the bark, creating wounds that are an open invitation for pests and diseases.

Constant foot traffic can also wear away the protective bark and compact the soil even further, stressing the tree. A wounded root is like a compromised immune system—it makes the entire tree vulnerable.

Signs of Tree Stress

Sometimes, exposed roots can be a symptom of a larger issue. If you notice the following signs in addition to surface roots, it might be time to pay closer attention:

  • Yellowing leaves (chlorosis) during the growing season.
  • Smaller-than-usual leaves or a thinning canopy.
  • Dead branches at the top of the tree (crown dieback).
  • Fungus or mushrooms growing on the roots or at the base of the trunk.

These symptoms, combined with damaged surface roots, could indicate that the tree is struggling and may need an expert evaluation from a certified arborist.

The Ultimate Trees with Exposed Roots Care Guide: Best Practices for a Healthy Tree

Ready for some good news? Caring for trees with exposed roots is easier than you think! It’s all about protection and creating a healthy environment. Follow these trees with exposed roots best practices to keep your tree happy for years to come.

The Magic of Mulching (The Right Way)

Mulch is your absolute best friend here. A 2- to 3-inch layer of organic mulch, like wood chips or shredded bark, over the root zone is one of the best things you can do.

Mulch helps to:

  1. Conserve moisture in the soil, reducing water stress.
  2. Regulate soil temperature, protecting roots from extreme heat and cold.
  3. Reduce soil compaction and prevent further erosion.
  4. Improve soil health as it breaks down over time.

Pro Tip: The most important rule of mulching is to create a “donut,” not a “volcano.” Never pile mulch directly against the tree trunk. Keep it pulled back a few inches to allow air circulation and prevent rot.

Watering Wisely

Exposed roots can dry out more quickly than their buried counterparts. During dry spells, give your tree a deep, slow watering. Instead of a quick daily sprinkle, use a soaker hose or let a regular hose trickle at the base for a few hours. This encourages deep root growth and ensures the water gets where it’s needed most.

Creating a “No-Mow” Zone

The easiest way to prevent mower damage is to stop mowing over the roots altogether! Expand the mulch bed around the base of the tree to cover all the exposed roots. This creates a physical barrier that protects the roots and eliminates the need to navigate a lawnmower through a root-filled obstacle course.

What NOT to Do: Common Mistakes That Can Harm Your Tree

Sometimes, knowing what not to do is just as important as knowing what to do. Here are a few common but harmful mistakes gardeners make when trying to “fix” exposed roots.

Don’t Cover Roots with Topsoil

This is the number one mistake I see people make! It seems like an intuitive solution—if the roots are exposed, just cover them with dirt, right? Wrong.

Piling a thick layer of soil over the root system can suffocate the tree. Roots need to exchange gases with the atmosphere, and burying them cuts off their oxygen supply. This can lead to root rot and will slowly, but surely, kill a mature tree. A thin layer of mulch is okay; a thick layer of soil is not.

Never Cut Major Roots

It can be tempting to just saw off a problematic root that’s lifting a paver or creating a tripping hazard. Please, resist the urge! Cutting large, structural roots can have two devastating effects:

  1. It can destabilize the tree, making it more susceptible to falling in a storm.
  2. It creates a massive wound that is a prime entry point for decay and disease.

If a root absolutely must be removed, it’s a job for a certified arborist who can assess the risk and do it safely.

Creative & Eco-Friendly Landscaping: Turning Exposed Roots into a Garden Feature

Now for the fun part! Instead of seeing a problem, let’s look at this as a creative opportunity. Here’s how to trees with exposed roots can become a beautiful and integral part of your garden design, using sustainable and eco-friendly methods.

Plant a Shade-Tolerant Groundcover

One of the best ways to handle the area is to establish a living mulch with a beautiful groundcover. The key is to choose plants that tolerate dry shade and won’t compete too aggressively with the tree for water and nutrients.

Look for small plants or plugs that you can gently tuck into the soil pockets between the roots, minimizing disturbance. Some fantastic options include:

  • Periwinkle (Vinca minor): A tough, evergreen groundcover with lovely blue or white flowers.
  • Bugleweed (Ajuga reptans): Forms a dense mat with spikes of blue flowers in the spring.

    • – Hostas: Come in endless varieties of foliage and are perfect for shady spots.

  • Japanese Pachysandra (Pachysandra terminalis): A classic, lush, evergreen choice for deep shade.

Create a Natural Mulch Bed or Island

Embrace the “no-mow” zone by turning it into a deliberate landscape feature. Define the area around the tree with a natural-looking border of stones or a simple spade edge. Fill the bed with a 2-3 inch layer of organic mulch.

This creates a clean, intentional look that protects the tree and reduces your lawn maintenance. It’s a simple, sustainable trees with exposed roots solution that looks fantastic.

Build a Raised Deck or Walkway

For areas with extremely dense surface roots where even groundcover is a challenge, consider building a small, low-level deck or a floating walkway over the area. This allows you to enjoy the space without compacting the soil or damaging the roots. It can create a beautiful, tranquil seating area beneath the canopy of your favorite tree.

Frequently Asked Questions About Trees with Exposed Roots

Can I just add a thick layer of soil over exposed tree roots?

No, please don’t do this! Adding more than an inch or two of soil can suffocate the roots by cutting off their oxygen supply. This is one of the most common ways people accidentally harm their mature trees. Stick to a 2-3 inch layer of organic mulch instead.

What are the best plants to grow around exposed roots?

The best choices are shade-tolerant, shallow-rooted plants that don’t require a lot of water. Think groundcovers like Ajuga, Vinca Minor, Sweet Woodruff, or Epimedium. Small ferns and Hostas also work well. Always plant small plugs to minimize root disturbance.

Is it safe to cut an exposed tree root that’s lifting my sidewalk?

Cutting any root larger than a couple of inches in diameter can compromise the tree’s stability and health. For issues with sidewalks or foundations, it’s always best to consult a certified arborist. They can offer solutions like root pruning or installing root barriers that won’t jeopardize the entire tree.

Your Tree’s Roots Are a Story, Not a Problem

Those sprawling roots tell the story of your tree’s life—its search for water, its adaptation to the soil, and its resilience over the years. By understanding their needs and working with them, you can ensure that story continues for many more seasons.

Remember the key takeaways from our trees with exposed roots guide: diagnose the cause, protect the roots from damage, use mulch generously (but properly!), and never suffocate them with soil. Most of all, get creative! A well-cared-for root zone can become a beautiful, low-maintenance, and thriving part of your garden.

So go on, take another look at those roots. Don’t see a problem—see an opportunity to become an even better partner to the beautiful trees in your care. Happy gardening!
