Should You Landscape Around Trees?

Landscaping around trees: should you do it? Well, yes and no.
Beautifying nature is always a fun and exciting idea, especially when wanting to make it a focal point for your home. But maintenance of landscape health is important, too!
Before we dive in, here’s a brief overview of “Do’s and Don’ts” to remember when implementing your next landscape idea:
DO’S
- Plant flowers or small shrubs around the tree
- Be extremely watchful of tree roots
- Mimic the forest floor
- Plant trees far away from retaining walls
- When in doubt, contact your Certified Arborist
DON’TS
- Tackle a big landscape project (hardscaping, patios, landscape lighting, etc.) without contacting your Certified Arborist
- Cut tree roots
- Put landscape fabric or weed mats around tree
- Add rocks around trees
- Add more than a few inches of mulch or wood chips around the base of the tree trunk
- Excavate or change the grade
- Build a raised garden bed around tree
Landscaping Around Tree Roots

When landscaping around trees, the #1 thing you need to watch out for is your tree’s roots.
The critical root zone (CRZ) is your tree’s life system. By hacking or cutting through these crucial “veins,” you risk severe tree damage, root rot, and eventual tree mortality.
Here’s an easy trick: To find the CRZ, look out for the tree’s drip line.
You can do this by envisioning your shade tree like it’s an umbrella – if it were to rain, where would the rain go? It would go where the edges of the canopy reach out.
Underneath this umbrella is the caution zone.
Z-mark the area. Know the area. Protect the area.
Tree Care Tip #1: Envision a tree like it’s an umbrella, and protect everything underneath that area.
Small projects like flower beds or small shrubs minimally dig into the root zone. These should be fine, as long as you’re careful.
Tree Care Tip #2: If you’re doing a small project and find yourself on a tree root, just move a couple of inches to either side and you should be fine.
Now, you may be thinking, “Oh, but my builder, outdoor lighting guy, cable TV guy, they did work under that line. They all said it’s fine.”
Looking out for your trees may not be their number one priority, but it’s ours.
As tree experts, we’re here to speak for the trees. They’ve been with us for for a long time, and they deserve the best.
Q: Is it OK To Put Landscape Fabric Around Trees?

Many people make the mistake of thinking, “Yes, it’s ok to put landscape fabric around trees – we need to prevent weeds!”
But what if we told you that’s actually not the case?
In fact, not only are weeds okay around trees, but our Certified Arborists actively work to recreate the forest floor around the trees.
Trees were conditioned to grow in the natural forest floor. And what do forests have? Not artificial landscape fabric or weed barriers; they have weeds, sticks, leaves, and animals.
You should also avoid:
- Weed mats
- Landscaping around trees with rocks
- Mulch volcanoes
- Fill dirt
Tree Care Tip #3: Don’t see it done in nature? Don’t add it.
