Do you have a cedar tree in your yard, but aren't quite sure what to plant underneath it? Certain plants will grow much better underneath cedar trees, but how do you know which ones to pick? In this article, amateur gardener Jason White examines what kind of plants do well underneath cedar trees, as well as several of the most popular options.

Cedar Trees With Plants Underneath


Cedar trees are a favorite landscaping tree for many people all over the world. But finding the perfect plant to grow underneath them can be a bit of a challenge because of their structure, and root system.

Adding plants under any tree is a common technique for integrating that tree into a landscape and avoiding empty space. You can also create an interesting layering effect by adding a mix of ground cover and shrubs.

However, there are some important considerations when choosing these plants, especially for cedars. The wrong plants could harm nearby trees or not do well if they have to compete with the tree’s root system for water and nutrients. Read on to learn more about cedar trees and which plants do well underneath them.

A Few Facts About Cedar Trees

Cedar trees belong to the Pinaceae family. They’re native to the Himalayas and the countries that border the Mediterranean Sea.

These evergreen trees are incredibly resilient. They don’t need a lot of water and thrive in slightly acidic soil with no fertilizer. The only maintenance they require is the occasional mulching and some light pruning. You’ll also have to water regularly when you first plant a cedar tree, but adult trees only need rainwater.

Cedars need plenty of sun. They grow rapidly and do well in Zones 7 through 9A, but it’s a very versatile tree that can adapt to different conditions.

There are a few diseases to watch out for, including cedar-apple rust, a type of fungal disease that affects cedar trees and apple trees. Port-oxford-cedar root disease is a condition that can spread through soil movement.

Should You Plant Under Your Cedar Tree?

Whether you are just planting your tree, or have a mature tree, there are several benefits to planting under a cedar.

Besides improving the aesthetics of your yard, plants that grow underneath your cedar tree can help loosen the soil and help the tree’s root system absorb more oxygen and nutrients.

Another benefit is that plants will absorb excess water and help create ideal conditions for the cedar, especially if you live in an area with heavy precipitations. If water accumulates at the base of a tree, it can make the soil too compact and make it difficult for the roots to grow.

Plant Choice Considedrations

Some plants do well under cedars and others don’t. Cedars thrive in soil that is slightly acidic, but they can grow in soil with a pH of anywhere from 5.5 to 7.2, so don’t assume your garden soil is necessarily acidic if you have a cedar tree. It’s best to test the soil before selecting plants that will go underneath the tree, to figure out whether you should select species that do well in acidic soil or not.

Shade can be a challenge. Cedars are evergreens with dense foliage. Cedars can provide similar challenges to growing under other shade trees like oaks. Depending on the cedar variety, they can cast a big area of shade, making planting underneath them a challenge.

The dripline can be another issue. Because of the dense foliage, water will drip where it ends and create a zone that could get saturated with water.

The root system can vary from one type of cedar tree to another, but lots of trees in that family have shallow and fibrous roots. Limiting the number of plants you add around the tree is important so the tree can still get the water and nutrients it needs from the soil.

Caring for Plants Under a Cedar Tree

There are some considerations you’ll need to factor in when planting under cedars.

Here are a few additional things to keep in mind before learning more about which plants do well under cedars:

  • Avoid adding more plants if you have a young tree.
  • You can plant some shrubs or ground cover once the tree has matured.
  • Remember that cedars have shallow roots.
  • Be careful and dig around these roots when planting new shrubs.
  • Raised beds might look great, but they can suffocate a tree’s root system.
  • It’s best to add plants directly into the soil near your cedar tree.
  • Cedars don’t need a lot of water.
  • In fact, soil with too much moisture can suffocate their root system.
  • Avoid planting shrubs or ground cover that would require frequent watering.
  • Prune your cedar’s branches to any plants underneath get adequate light.
