Introduction
Douglas fir trees are majestic evergreens that add beauty and shade to any garden or landscape. They are also great for absorbing carbon dioxide and producing oxygen, making them an excellent choice for the environment. While they offer many benefits, it's essential to choose the right plants to grow under Douglas fir trees to ensure they thrive in the shade and acidic soil.
Choosing the Right Plants
When selecting plants to grow under Douglas fir trees, you need to consider the amount of sunlight and acidity of the soil. These trees can grow up to 200 feet tall, so it's crucial to choose plants that can handle partial shade or full shade. Additionally, the soil around these trees tends to be acidic, so you must select plants that can tolerate these conditions.
Ground Covers
Ground covers are a great option for planting under Douglas fir trees as they can help retain moisture and increase soil nutrients. Some good choices for ground covers include Oregon grape, Salal, and Bearberry. These plants are also suited to the acidic soil conditions found under Douglas fir trees.
Small Shrubs and Perennials
Small shrubs and perennials are another option for planting under Douglas fir trees. These plants can add color and texture to the area while also providing some shade. Dwarf Rhododendrons, Huckleberry, and Kinnikinnick are good choices for small shrubs, while Bleeding Heart, Hosta, and Ferns are great perennials that can thrive in partial or full shade.
Vines
Vines are a unique way to add additional shade under Douglas fir trees while also adding beauty to the space. Climbing Hydrangea, Honeysuckle, and Virginia Creeper are all great options for vines that can grow in partial or full shade. These plants will also tolerate the acidic soil common to Douglas fir tree areas.
Avoid These Plants
While many plants can thrive under Douglas fir trees, some should be avoided. Plants such as Azaleas, Blueberries, and Camellias are not recommended as they require an alkaline soil and cannot tolerate the acidic soil found under Douglas fir trees. Additionally, plants that require full sun should also be avoided, as the shade from the trees will prevent their growth.
Conclusion
Planting under Douglas fir trees requires careful consideration of the shade levels and acidity of the soil. Groundcovers, small shrubs and perennials, and vines are great options for adding color, texture, and shade to the area. However, it's important to avoid plants that require alkaline soil, such as Blueberries and Azaleas. With the right plant selection, you can create a beautiful ecosystem under your Douglas fir tree that will thrive for years to come.
