Introduction

Aspen trees (Populus tremuloides) are a common sight in North America. They are fast-growing deciduous trees that can reach 50-80 feet tall. Aspens are often used for landscaping, but they can be challenging to plant under due to their root system and canopy. In this article, we will discuss what to plant under aspen trees to make the most of your landscaping.

Challenges of Planting Under Aspen Trees

Aspens have a shallow and extensive root system that can impact the growth of other plants near them. The roots of aspen trees can quickly consume water and nutrients from the soil, making it challenging to grow other plants. They also create a dense canopy that shades the ground, limiting the amount of sunlight that reaches the soil. Furthermore, the leaves of aspen trees have a high water content, which makes the soil under the tree moist, creating an ideal environment for fungal growth.

What to Plant Under Aspen Trees

Despite the challenges of planting under aspen trees, there are still some plants that can thrive. Here are a few options to consider:

1. Wildflowers

Wildflowers are an excellent option for planting under aspen trees. They are adapted to the dry and nutrient-poor soils found under aspen trees. Wildflowers like columbine, lupine, and penstemon can add color and attract pollinators to your garden. They also grow well in the shade, which is ideal for the understory of aspen trees.

2. Groundcovers

Groundcovers like creeping phlox and thyme are also great options for planting under aspen trees. They are low-growing, which makes them ideal for planting in small spaces. Groundcovers can help retain moisture in the soil and prevent weed growth. They also add texture and color to the ground under the tree.

3. Ferns

Ferns are a great option for planting under aspen trees. They love the cool and moist environment found under the shady canopy of aspen trees. Ferns like lady fern and ostrich fern can also add texture and color to your garden. They also require little maintenance, making them an easy addition to your landscaping.

Tips for Planting Under Aspen Trees

Here are some tips to keep in mind when planting under aspen trees:

1. Prepare the soil before planting by adding compost or organic matter to improve soil fertility.

2. Choose plants that are adapted to dry and nutrient-poor soils.

3. Use mulch to help retain moisture in the soil and prevent weed growth.

4. Water plants regularly, especially during the summer months.

Conclusion

Planting under aspen trees can be challenging, but with the right plants and care, it is possible to create an attractive garden. Wildflowers, groundcovers, and ferns are ideal for planting under aspen trees. Remember to prepare the soil, choose plants that are adapted to dry and nutrient-poor soil, and water plants regularly. With these tips in mind, you can create a beautiful and thriving garden under your aspen trees.
