What to Plant Around the Base of a Tree

Planting around the base of a tree can be a challenging task. Choosing the right plants means finding those that can thrive in the shade and compete with the tree's roots. The wrong plant could suffer or even die, which might be a sight unpleasant to see. Choosing the right plants comes down to making several considerations, including soil type, tree species, light exposure, and available space.

Considerations for Choosing Plants

The first thing to consider when choosing plants to grow around the base of a tree is the tree species. Different tree species have different requirements when it comes to light, water, and soil type. For instance, some trees, such as oak and hickory, have shallow root systems, and their shade is denser, making it difficult for understory plants to grow. In such a case, plants that thrive in full shade and poor soil could be a good choice, such as ferns or hostas. For other trees that don't provide dense shade or have extensive roots, plants that need partial sunlight, such as primrose or geraniums, could be a good choice.

The soil type around the base of the tree is also essential. Most trees prefer healthy soils with a pH neutral to slightly acidic. If the soil is clayey, it might be challenging to grow plants that require constant moisture. Adding organic matter or a layer of topsoil could help improve the soil, thus increasing the chances of success for plant growth. Native plants could be a better choice as they have adapted to local conditions and have lower requirements when it comes to maintenance.

Plants to Grow

The plants you choose to grow around the base of a tree might depend on the tree's size and the available space. For instance, for a small space, ground-cover plants such as ajuga, pachysandra, or lily-of-the-valley could be a good choice. These will create a carpet-like effect, covering the soil with their leaves, and also prevent weed growth.

For a larger space, consider adding shrubs such as mountain laurel, azaleas, hydrangeas, or rhododendrons. These will provide a more significant visual impact with their colorful blooms, and some can also provide nectar to pollinators. For a more natural look, consider adding ferns, such as Christmas fern or the sensitive fern, or wildflowers. These will create a woodland setting and also provide habitats for wildlife.

How to Plant the Seeds

After choosing the plants to incorporate, the next crucial step is how to plant them. Remember, adding new plants close to the tree could damage the roots if done haphazardly. Thus, take care not to disturb the roots while planting. Here are some essential tips for planting:

Remove any grass or weeds from the area around the tree.

Apply a layer of mulch over the soil. This will help retain moisture and control weed growth. Also, it will keep the soil cool and prevent the roots from drying out in hot weather.

Plant the new plants in a hole at least two times the diameter of the root ball. This allows enough space for root spread and soil drainage.

Back-fill the hole with soil, taking care not to damage the roots. Compact the soil gently to avoid air pockets.

Water the new plants well for the first few weeks to help the plants establish their roots.

Conclusion

Planting under a tree is a great way to create a beautiful landscape while enhancing the tree's beauty. Choosing the right plant can be challenging, but with proper planning, it's possible. Consideration of factors such as soil type, tree species, and lighting help to make the right choice of plant. Once you've selected the right plants, follow best practices to plant them correctly and ensure they thrive.
