Beware of Volcanoes…

Recently we planted an expensive tree in one of our installations. As we were planting, we noticed that there was no visible root-flare on the tree. The root flare is the part of a tree that should be above ground and tapers down to where the roots start growing.

We doctored the tree and exposed this flare. As you can see, the growers continually piled dirt on top, eventually covering the trunk by a good four to five inches. When this happens, or when landscapers “volcano mulch” a tree, many risks may occur.

Tree roots need oxygen, and this is why it’s very normal for them to grow at the surface of the soil. If dirt is piled on the tree, roots may “girdle” the tree looking for oxygen, choking the tree. Where the dirt is piled, fungus, bugs, or rot may harm a tree. Also, as you can see in the photos, the tree may respond by growing “adventitious roots,” a process in which the tree is trying to adapt and survive.

Make sure when you spend your money on landscaping, you install the plants properly. Planting plants too low and volcano mulching is incredibly common. This ensures your landscaping, and your wallet, is actually low-maintenance... Happy planting!
