Can I Plant Ferns Under My Sugar Maple Tree?

Sugar maple trees are popular landscape trees because of their beautiful foliage and sturdy structure. Ferns, on the other hand, are a popular groundcover plant that can add texture and color to your garden. Many gardeners ask if they can plant ferns under their sugar maple tree, and the answer is yes, but with some caveats.

Consider the Shade

Sugar maple trees are known for their ability to create dense shade beneath their canopy. Ferns, particularly ones that grow well in the shade, need a certain amount of sunlight to thrive. When planting ferns under a sugar maple tree, it is important to choose a species that can tolerate low light conditions. Some popular ferns that grow in partial shade or shade include lady fern, maidenhair fern, and royal fern.

Maintain Moisture

Ferns prefer to grow in moist soil, and the dense canopy of a sugar maple tree can help retain moisture in the soil. However, the tree's extensive root system can also compete for water, so it is important to make sure that the ferns are getting enough water. Regularly watering the ferns during dry spells can help ensure they remain healthy and vibrant.

Watch for Competition

While ferns can grow under sugar maple trees, they may have to compete with the tree's roots for nutrients. This can be problematic because sugar maple trees have an extensive root system that can outcompete other plants. To avoid this issue, it is best to plant ferns at a distance from the tree's trunk. This will give the ferns more space to grow and will allow them to access nutrients more easily.

Consider Companion Planting

Companion planting involves planting two or more species that complement each other in the same garden bed. Ferns work well as a companion plant for sugar maple trees because they can provide groundcover and help retain moisture in the soil. Other plants that work well as companion plants for sugar maple trees include hostas, caladiums, and astilbes.

Conclusion

Ferns can add beauty and texture to your garden, and they can thrive under the canopy of a sugar maple tree. By choosing the right species of fern, maintaining proper moisture levels, watching for root competition, and considering companion planting, you can create a beautiful and healthy garden bed that combines the best of both worlds.
