How Close Can I Plant Under Trees?

Many people enjoy the beauty and shade that trees bring to their yard, but may not know how to properly plant underneath them. While trees offer many benefits, planting too close can have negative effects on both the tree and any plants beneath it. In this article, we will explore how close you should plant under trees to ensure both a healthy tree and a thriving garden.

Factors to Consider

When deciding how close to plant under trees, there are a few important factors to consider:

Tree size: The larger the tree, the further away you should plant. Large trees have extensive root systems that can disrupt the growth of nearby plants.

Tree species: Some tree species have shallow roots that spread outwards, while others have deeper roots that grow vertically. Knowing the types of trees in your yard can help you determine where to plant.

Soil quality: The soil quality under trees can be poor due to the tree's roots absorbing most of the nutrients. This can make it difficult for plants to grow.

Recommended Planting Distances

Based on the above factors, it is generally recommended to plant at least 3-6 feet away from the trunk of a small to medium sized tree, and 10-15 feet away from a large tree. If the tree has shallow roots, it is best to plant even further away to avoid root competition.

Additionally, it is important to avoid planting directly under the canopy of the tree. This area is also known as the "drip line" and is where rainwater drips from the tree. Planting in this area can make it difficult for your plants to receive adequate water and nutrients.

Plant Selection

Choosing the right plants to grow under trees is also crucial for their success. Shade-loving plants that do well in nutrient-poor soil are the best choices. Some options include:

Hostas

Ferns

Lungwort

Pulmonaria

Astilbes

Brunneras

It is important to also consider the height of the plants you choose to plant under trees. You do not want them to grow so tall that they compete with the tree for sunlight. Lower growing plants are a better choice for this reason.

Maintenance

When planting under trees, it is important to keep your plants well-maintained. This includes regular watering and occasional fertilization to ensure they receive the necessary nutrients. Be sure to also remove any weeds or other plants that may compete with your chosen plants for resources.

Another important consideration is the amount of sunlight that reaches the plants. Depending on the location of the tree and its canopy, plants growing underneath may only receive a limited amount of sunlight each day. Be sure to keep this in mind when selecting your plants and consider adding artificial lighting if necessary.

Conclusion

Planting under trees can be a challenge due to the competition for resources from the tree's roots and canopy. However, with proper consideration given to planting distances, plant selection, and maintenance, it is possible to create a beautiful and thriving garden. By following the guidelines outlined in this article, you can ensure the health of both your tree and the plants growing beneath it.
