Introduction

Redwood trees, also known as coast redwood trees or Sequoia sempervirens, are abundant in California and the Pacific Northwest regions of the United States. Known for their towering height and long lifespan, redwood trees are a popular choice for homeowners looking to add natural beauty and shade to their landscape. However, one major challenge with planting under redwood trees is the dense shade they provide, which can make it difficult for other plants to thrive.

Factors to Consider

Before deciding what to plant under redwood trees, it is important to consider a few factors. First, the amount of sunlight that reaches the area will determine which plants are viable. Redwood trees provide dense shade, which means that only a few hours of sunlight usually penetrate through the canopy each day. Second, the acidity of the soil can impact the growth of certain plants. Redwood trees prefer slightly acidic soil, typically in the 5.5 to 6.5 pH range. Finally, the root system of redwood trees is shallow and can spread out over a wide area, which can limit the space available for other plants to grow.

Plants that Thrive in Shade

Despite the challenges presented by the dense shade of a redwood tree, there are several types of plants that thrive in low light conditions. Ferns, for example, are an excellent choice for underplanting a redwood tree. They are naturally adapted to growing in damp, shady environments and have a delicate texture that can contrast nicely with the rough bark of the redwood tree. Other shade-loving plants that can flourish under redwood trees include hostas, astilbes, and coral bells.

Groundcovers

Groundcovers are a great option for planting under redwood trees because they do not grow tall enough to compete with the canopy of the tree. Instead, they creep along the ground and can provide a lush carpet of foliage. Some popular groundcovers for underplanting a redwood tree include violets, creeping thyme, and periwinkle. Another groundcover option is a shade-tolerant grass, such as sedge or Carex. These can provide a more lawn-like appearance while still thriving in low light conditions.

Planting Considerations

When planting under a redwood tree, it is important to be gentle with the tree's root system. Avoid digging too deeply or disturbing the soil around the tree, as this can cause damage to the roots. Instead, place plants in the spaces between the roots or in holes that are carefully dug around them. Consider adding a layer of mulch around the plants to help retain moisture and regulate soil temperature. Finally, keep in mind that redwood trees are known for their ability to absorb water and nutrients from the soil, which means that other plants may need to be fertilized or watered more frequently to thrive.

Conclusion

Planting under a redwood tree may be challenging, but with the right plants and planting techniques, it is possible to create a lush and beautiful underplanting. As with any landscaping project, it is important to consider the unique characteristics of the area and choose plants that are adapted to the conditions. With a little planning and care, your redwood tree can become the centerpiece of a stunning and thriving landscape.
