What to Plant Under Live Oak Trees

Live oak trees are known for their grandeur and longevity, with some trees living up to 600 years old. However, as they grow and mature, they also create a challenging environment for anything planted beneath their canopy. Understanding what to plant under live oak trees can help you create a beautiful and sustainable landscape.

Considerations for Planting Under Live Oak Trees

Before you start planting, there are a few things you need to consider. Live oak trees have an extensive root system that can spread up to three times the diameter of the canopy. The trees also create dense shade, which limits the amount of sunlight that reaches the ground beneath them. Finally, live oak trees are allelopathic, which means they release chemicals that can harm or stunt the growth of other plants.

Native Texas Plants That Thrive Under Live Oak Trees

Despite the challenges, there are still plenty of native Texas plants that can thrive under live oak trees. One option is to create a natural understory of ferns and other shade-loving plants. One popular plant is the Texas maidenhair fern, which has delicate fronds that add texture and movement to the garden. Other good choices include wild ginger, violets, and heartleaf philodendron. These plants can add a pop of color and texture to the landscape while also providing a home for beneficial insects and wildlife.

Groundcovers for Live Oak Trees

Another option is to use groundcovers to fill in the space beneath the live oaks. Native Texas groundcovers, like horseherb or frogfruit, can provide an open canopy for other plants to grow while also suppressing weeds. Vinca, creeping thyme, and liriope are also popular groundcovers that thrive in partial shade. Keep in mind that it is essential to use native plants when planting under live oak trees, as non-native plants can be more susceptible to the allelopathic compounds released by the trees.

Care Tips for Plants Under Live Oak Trees

Once you have planted your new landscape, there are a few care tips to keep in mind. First, it is essential to water regularly, especially during the establishment phase. However, it is also essential not to overwater, especially in the winter when the trees go dormant. Second, pruning is essential for both the trees and the plants beneath them. Remove any dead or diseased branches from the trees, and prune any plants that may be shading out others or growing too tall. Finally, it is essential to use organic fertilizers and pest control measures when necessary, as many chemical treatments can harm both the plants and the trees.

In Conclusion

In conclusion, planting under live oak trees can create a beautiful and sustainable landscape. By choosing the right plants for the environment and following proper care guidelines, you can create a picturesque setting that benefits both the trees and other wildlife. From ferns and groundcovers to native perennial flowers and shrubs, there are plenty of plant options to create a thriving and joyful landscape beneath the majestic live oaks.
