Placing landscaping rocks or gravel around ornamental trees is a simple way to enhance your property’s aesthetic. But is gravel or rock mulch bad for trees?
As a leading provider of tree services in Boerne, TX, we’re here to answer the question, “Will placing rocks around a tree kill it?” Learn how landscaping rocks affect tree roots and growth over time and what you can do to protect your vegetation.
Instead of Rocks, Consider These Alternative Landscaping Options
Some people prefer something other than grass surrounding the base of their trees. However, gravel may not be the best solution. Arborists often encourage homeowners to use mulch instead.
It enhances the overall look of the landscape, helps suppress weeds, and protects the root system. Just make sure to apply the mulch evenly over the root zone instead of forming a volcano shape around the base of the trunk.
Landscaping fabric is another solid alternative. No matter which option you choose, keep up with standard tree care like watering and fertilizing the soil, as well as pruning dead or overgrown branches.
The Harmful Effects of Placing Rocks Around Trees
How will putting rocks around a tree kill it? Decay may not happen right away, but the placement of the rocks can gradually cause irreparable damage. Below is a breakdown of how landscaping rocks impact a tree’s vitality.
Soil Compaction
Tree roots need loose soil to expand. When the soil becomes compacted, they have no room for growth, which ultimately impacts the tree’s overall health. The weight of the rocks gradually compacts the soil and robs the roots of the necessary oxygen.
Lack of Nutrients
How else can rocks around trees cause root damage? Unlike mulch or wood chips, landscaping rocks do not have any organic matter that will break down over time and supply the soil with nutrients. As a result, the roots can become starved and lead to widespread decay.
Poor Moisture Retention
Trees don’t just need sunlight and soil to survive. Their health is often dependent on the amount of water they receive.
Placing landscaping rocks around a tree is not ideal, since the material can hinder water retention. Even a thin layer of gravel can affect the soil’s ability to retain moisture, meaning it could quickly dry out. Experts recommend using mulch because it helps the soil retain moisture, which may also impact your watering schedule.
