Landscaping Around Exposed Tree Roots: Turning Tripping Hazards Into

ByRimon Chowdhury Updated on

Let’s be honest—those gnarled, exposed tree roots snaking across your lawn are a bit of a headache, aren’t they? They make mowing a treacherous obstacle course, create a tripping hazard for guests, and stubbornly refuse to grow a decent patch of grass.

I promise you, this garden challenge isn’t a lost cause. In fact, it’s a golden opportunity! With the right approach, you can stop fighting those roots and start working with them to create a stunning, low-maintenance garden feature that not only looks beautiful but also protects the health of your beloved tree.

In this complete guide to landscaping around exposed tree roots, we’ll walk through everything you need to know. We’ll cover the crucial “don’ts” that can harm your tree, explore beautiful and practical planting solutions, and give you a step-by-step plan to turn that tricky spot into the envy of the neighborhood. Let’s dig in!

Why Are My Tree Roots Exposed? Understanding the Root of the Problem

Before we grab our trowels, it helps to understand why those roots are making an appearance. It’s usually not a sign that your tree is sick; more often, it’s a natural part of its life cycle.

The primary culprits are often:

  • Soil Erosion: Over time, wind and rain can wash away the top layers of soil, slowly revealing the shallow roots that were once just beneath the surface. This is especially common on slopes.
  • Soil Compaction: Heavy foot traffic (from people, pets, or lawnmowers) can compact the soil. Roots need oxygen to thrive, so they may begin to grow closer to the surface where the soil is less dense.
  • Natural Growth: Some tree species, like maples, beeches, and oaks, are simply genetically programmed to have shallow root systems. As the tree matures and its roots thicken, they naturally push up and break the surface.

Seeing these roots means you have a mature, established tree—and that’s a wonderful thing! Our goal now is to protect them while beautifying the space. This is where the benefits of landscaping around exposed tree roots truly shine.

The Cardinal Sins: Common Problems and What to AVOID When Landscaping Around Exposed Tree Roots

I’ve seen too many well-intentioned gardeners accidentally harm their beautiful, mature trees. Before we talk about what to do, let’s cover the absolute must-nots. Avoiding these common mistakes is the most critical part of this entire process.

Don’t Bury the Roots with Soil

This is the most common and damaging mistake. It seems like a simple fix, right? Just dump a few bags of topsoil over the roots and throw down some grass seed. Please don’t do this!

A tree’s shallow “feeder” roots are responsible for absorbing oxygen, water, and nutrients. Piling more than a couple of inches of soil on top of them effectively suffocates them. This can lead to a slow, painful decline and may eventually kill the tree.

Don’t Damage the Roots

Those large, woody roots are like the tree’s arteries. Hacking at them with a shovel, running them over with a tiller, or cutting them to make way for a new path can create open wounds. These wounds invite pests and diseases that can seriously compromise the tree’s health. Never cut a root larger than your wrist, and even then, avoid it unless absolutely necessary and after consulting an arborist.

Don’t Build a Raised Bed Right Against the Trunk

While a raised bed can seem like a clever solution, building one that boxes in the tree’s trunk is a recipe for disaster. Piling soil and mulch against the “root flare” (where the trunk widens at the base) traps moisture against the bark. This promotes rot and decay, which can girdle and kill the tree.

Don’t Plant Grass

You’ve probably already discovered this one the hard way. Grass is a losing proposition under a mature tree. It struggles to compete with the tree for water and nutrients and can’t handle the deep shade. Trying to force it is a waste of time, money, and effort.

Your Step-by-Step Guide: How to Landscaping Around Exposed Tree Roots Safely and Beautifully

Ready for the fun part? This is our blueprint for creating a gorgeous, tree-friendly garden bed. This complete landscaping around exposed tree roots guide breaks it down into simple, manageable steps.

  1. Gentle Cleanup: Start by carefully removing any existing turf or weeds from the area. Don’t use a sharp spade or tiller! Your best tools are your hands or a small hand rake. Gently pull or scrape away the unwanted vegetation, being careful not to gouge the roots.
  2. Add a Thin Layer of Soil & Compost: To give your new plants a healthy start, add a very thin layer—no more than 1 to 2 inches—of a 50/50 mix of high-quality compost and topsoil. This isn’t for burying the roots; it’s to create small pockets of nutrient-rich medium for your new plants to establish themselves in.
  3. Choose the Right Plants: This is key! You need plants that can handle dry shade and won’t compete aggressively with the tree. We’ll dive deep into the best plant choices in the next section. For now, think small, shallow-rooted, and shade-tolerant.
  4. Plant with Care: When you’re ready to plant, look for the natural pockets and dips between the tree roots. Use a small trowel or even just your hands to gently create a planting hole. Buy smaller plants (in 4-inch pots or as “plugs”) as they are much easier to tuck into these tight spaces without disturbing major roots.
  5. Mulch Generously: Once your plants are in, apply a 2 to 3-inch layer of organic mulch, like shredded bark, wood chips, or leaf mold. Mulch is your best friend here! It helps retain moisture, keeps the soil cool, suppresses weeds, and mimics a natural forest floor. Important: Keep the mulch a few inches away from the tree’s trunk to prevent rot.
  6. Water Wisely: Your new plants will need consistent water for the first few months to get established. The tree canopy can act like an umbrella, so you can’t always rely on rain. Water deeply and slowly, allowing it to soak in rather than run off.

The Best Plants for Landscaping Around Exposed Tree Roots

Choosing the right plants is one of the most important landscaping around exposed tree roots tips I can offer. You’re looking for tough-but-beautiful plants that thrive in the challenging conditions of dry shade and don’t mind sharing space.

Low-Maintenance Groundcovers

Groundcovers are fantastic because they create a “living mulch” that spreads to fill the area, suppressing weeds and creating a lush, uniform look.

  • Ajuga (Bugleweed): This tough-as-nails groundcover forms a dense mat of attractive foliage (in shades of green, bronze, or burgundy) and sends up lovely blue flower spikes in the spring.
  • Pachysandra (Japanese Spurge): A classic choice for a reason! It creates a rich, evergreen carpet that looks elegant and requires almost zero care once established.
  • Vinca Minor (Periwinkle): Known for its glossy green leaves and pretty periwinkle-blue flowers, this is a vigorous grower that can quickly cover a large area. Just be sure to keep it contained, as it can be aggressive.

Shade-Loving Perennials

These plants return year after year, adding texture, color, and interest to your new garden bed.

  • Hostas: The undisputed kings of the shade garden! With thousands of varieties offering different leaf sizes, colors, and textures, you can create a stunning tapestry with hostas alone. Don’t worry—these flowers are perfect for beginners!
  • Ferns: Nothing says “woodland garden” like a fern. Try the delicate Japanese Painted Fern for its silvery fronds or the hardy Ostrich Fern for a taller, more dramatic look.
  • Hellebores (Lenten Rose): These are true gems. They are evergreen in many climates and produce beautiful, downward-facing flowers in late winter or early spring when nothing else is blooming.
  • Epimedium (Barrenwort): An underused superstar! It’s incredibly drought-tolerant once established and has delicate, orchid-like flowers and heart-shaped leaves that often turn bronze in the fall.

Sustainable and Eco-Friendly Landscaping Around Exposed Tree Roots

Creating a garden around your tree is a perfect opportunity to practice sustainable gardening. Adopting an eco-friendly landscaping around exposed tree roots approach benefits your tree, your garden, and the local environment.

Think of the area under your tree as a mini-forest ecosystem. Use organic mulches like shredded leaves or wood chips. These materials break down over time, enriching the soil naturally and providing a habitat for beneficial insects and microbes—just like on a real forest floor.

Even better, focus on planting native species. Native plants are adapted to your local climate, soil, and rainfall patterns. This means they’ll require less water, no fertilizer, and will provide vital food and shelter for local pollinators and birds. This is one of the top landscaping around exposed tree roots best practices for a truly resilient garden.

Your Landscaping Around Exposed Tree Roots Care Guide

Once your new garden is planted, a little ongoing care will ensure it thrives for years to come. This simple landscaping around exposed tree roots care guide will keep everything healthy and happy.

Watering

For the first year, your new plants are the priority. Water them deeply once or twice a week, especially during dry spells. After they are established, they will be much more self-sufficient, but an occasional deep watering during a drought will benefit both the plants and the tree.

Fertilizing

Less is more. Your mature tree likely doesn’t need extra fertilizer. A yearly top-dressing of compost for your perennials and groundcovers is usually all that’s needed. The decomposing organic mulch will also provide a slow, steady supply of nutrients.

Long-Term Maintenance

Each spring, check your mulch levels and add a fresh layer if it has decomposed to less than 2 inches. Rake up fallen leaves in the autumn and either shred them to use as mulch or add them to your compost pile. Divide any perennials like Hostas if they become overcrowded every few years.

Frequently Asked Questions About Landscaping Around Exposed Tree Roots

Can I just cover the exposed roots with a thick layer of mulch?

Yes! This is one of the simplest and best solutions. Applying a 2-3 inch layer of organic mulch (like wood chips) over the roots helps conserve moisture, moderate soil temperature, and prevent further erosion. It instantly improves the look and is fantastic for the tree’s health. Just remember to keep the mulch from touching the tree trunk directly.

Is it okay to cut some of the smaller tree roots to make space for planting?

It’s best to avoid cutting any roots if you can. The tiny, fibrous roots are the most active in absorbing water. If you absolutely must remove a root to fit a plant, only cut those that are smaller than your pinky finger. Never sever a large, woody anchor root.

How much soil can I safely add over exposed tree roots?

The golden rule is no more than two inches. Any deeper, and you risk cutting off the oxygen supply to the tree’s critical feeder roots. If you do add soil, make sure it’s a light, well-draining mix amended with plenty of compost.

Embrace Your Roots and Get Growing!

Those exposed tree roots don’t have to be a source of frustration. By understanding the needs of your tree and choosing the right companions, you can transform a problem area into a peaceful, thriving woodland garden.

Remember the key takeaways: work with your tree, not against it. Avoid damaging the roots, choose shallow-rooted plants that love the shade, and let organic mulch be your secret weapon. Your tree will be healthier, your yard will be safer, and you’ll have a beautiful new space to enjoy.

So grab your gloves and your trowel. It’s time to create something truly special. Happy gardening!
