Live oaks are more than just trees—they’re living landmarks. Their sweeping branches, deeply grooved bark, and evergreen presence are a defining feature of the Southern landscape. But as iconic as they are, landscaping around oak trees and beneath them requires careful thought. At Bayou Tree Service, tree preservation is at the heart of everything we do. That’s why we’ve partnered with Louisiana Nursery in Baton Rouge to help you build a beautiful, tree-friendly landscape under your live oaks.
In South Louisiana, landscaping with oak trees comes with a few common challenges, including dense shade, shallow feeder roots, and soil that compacts easily after heavy rain. The goal is to improve curb appeal without stressing the tree. Here’s how.
Quick Answer: Landscaping with Oak Trees
If you’re landscaping with oak trees, choose plants that tolerate shade, compete well for moisture, and do not require deep digging near surface roots. The best results come from light soil disturbance, the right mulch depth, and plant choices that thrive under live oaks.
Together with Louisiana Nursery, we’ve curated a plant list designed to thrive beneath these giants—plants that add beauty and color while coexisting symbiotically with the unique conditions under live oaks. These selections are based on what our certified arborists see every day in the field and what Louisiana Nursery knows will perform well in our Gulf South climate.

What to Plant Under Oak Trees: 5 Options
1. Camellias (blooms)
These evergreen shrubs are a Southern classic for a reason. With glossy leaves and elegant blooms from late fall through early spring, camellias are perfect for the filtered sunlight under live oaks. They bring a quiet elegance and seasonal interest without competing for root space in live oak landscaping.
2. Azaleas (blooms)
Another spring showstopper, azaleas thrive in acidic, well-draining soil and dappled light conditions naturally provided by mature live oaks. Their brilliant blooms offer a splash of color just when the landscape needs it most. Azaleas are an excellent addition to any live oak landscaping plan.
3. Mondo Grass (hardy)
This compact ground cover is tough, tidy, and incredibly low-maintenance. Mondo grass fills in space beautifully, prevents soil erosion, and holds up well in shady conditions. It’s a smart solution for problem areas in live oak landscaping that might not get much direct sunlight.
4. Autumn Fern (hardy)
Known for its coppery new growth that matures to a deep green, the autumn fern is a shade-loving, moisture-tolerant plant that brings soft texture and visual interest to the base of your oak. It’s a favorite for creating that lush, layered woodland look in your understory planting.
5. Bridal’s Wreath Spirea (native-friendly bloomer)
With its arching branches and delicate white spring blossoms, bridal’s wreath offers a romantic, old-fashioned look that pairs beautifully with the grandeur of a live oak. It thrives in partial shade and well-drained soil, making it an excellent fit for live oak landscaping in the South.

Tips for Planting Under Live Oaks
To keep your trees healthy while enhancing your landscape, it’s important to take a few precautions. Our arborists, along with resources from the LSU AgCenter, recommend the following best practices for landscaping around oak trees.
1. Avoid Disturbing the Critical Root Zone
The most important roots of a live oak are shallow and wide-spreading, often extending well beyond the drip line. Digging, driving, or compacting soil in this area can cause long-term damage to the tree. Learn more about the Critical Root Zone here.
2. Don’t Add Excess Soil
Instead of piling on new soil—which can suffocate the roots—work with what’s already there. Gently incorporate organic matter like compost or leaf mold into existing soil to improve its texture and nutrient profile.
3. Choose Low-Irrigation Plants
Live oaks prefer well-drained soil and don’t like to sit in overly wet conditions. Choose plants that can handle occasional dryness and won’t rely on constant irrigation to survive. Overwatering can stress the tree and promote root rot. This is especially important when planning landscaping under large shade trees like live oaks.
4. Water Thoughtfully
If irrigation is necessary (especially for new plantings), opt for drip systems or soaker hoses. These methods deliver moisture slowly and directly, minimizing waste and protecting the root zone from runoff.
5. Mulch Smart
A light layer of mulch (2–3 inches) helps retain soil moisture and keeps weeds down, but don’t let it touch the trunk. Pull mulch back a few inches to avoid trapping moisture against the bark. Learn about the importance of mulch here.

FAQs About Landscaping with Oak Trees
What is the best way to start landscaping with oak trees?
Start with the tree’s health first. Avoid major grade changes, keep foot traffic off the root zone when possible, and plan for plants that tolerate shade and drier soil between rain events. A 2 to 4 inch mulch layer helps protect roots and retain moisture, but keep mulch pulled back a few inches from the trunk.
What can we plant under oak trees in Louisiana?
Great options include mondo grass, liriope, azaleas, camellias, and ferns. These plants handle shade well and do not require aggressive digging. The best choice depends on how much sun filters through your canopy and how often the area stays moist.
How do we landscape around oak trees without damaging roots?
Use shallow planting methods and avoid trenching. Work with small plants, widen holes rather than digging deep, and place new plants between major surface roots instead of cutting through them. Mulch and targeted watering often do more for long-term success than heavy soil amendments.
Is it okay to add soil under a live oak tree?
Usually, we want to avoid adding significant soil over the root zone because it can reduce oxygen to roots and create stress. If soil improvement is needed, a thin layer of compost and proper mulching is typically safer than raising grade.
What is the best ground cover for landscaping under oak trees?
Mondo grass and liriope are two of the most reliable ground covers for landscaping under oak trees because they handle shade and establish without deep digging. In tighter root zones, we often recommend smaller plugs and patience instead of installing large flats that require more disturbance.
When should we mulch under oak trees and how much is too much?
Mulch is helpful year-round, especially ahead of hot weather. Keep mulch 2 to 4 inches deep, avoid “mulch volcanoes,” and leave a clear gap around the trunk. Too much mulch holds excess moisture against bark and can contribute to disease and root issues.
