The Dangers of Mulching Over Root Flares
Mulch is a fantastic way to improve soil health, conserve moisture, and suppress weeds around your trees. But there’s one crucial mistake that can seriously harm your trees: covering the root flare with mulch.
What is the Root Flare?
The root flare is the area where the trunk of the tree transitions from the main stem to its roots. It’s often hidden beneath the soil line due to improper planting.
Why is Mulching Over the Root Flare Harmful?
- Suffocation: Mulch piled over the root flare can block air circulation, leading to root rot and decay.
- Girdle: As the tree grows, the trunk can thicken and the buried mulch can girdle (constrict) it, preventing proper growth and potentially killing the tree.
- Disease and Pest Havens: Thick layers of mulch can create a moist environment that encourages the growth of harmful fungi and insects.
How to Properly Mulch Around Trees:
- Expose the Root Flare: Carefully remove any soil or mulch that is covering the root flare.
- Apply a Thin Layer: Spread a thin layer of mulch (2-3 inches) around the base of the tree, keeping it away from the trunk.
- Create a “Mulch Donut”: Create a donut of mulch around the trunk so the material isn’t piled against the trunk.
Remember: Proper tree care is essential for healthy trees and a beautiful landscape. By avoiding the mistake of mulching over the root flare, you can ensure your trees thrive for years to come. Do you need any help freeing any flares so they can breath? Let me know!
