How Bad Mulching Can Harm Trees and Lawns

However, if you’re not careful, you could actually cause harm to your trees and lawns. Read on to learn how to properly mulch your beds so you can avoid costly problems!

The Benefits of Mulch

Mulch is fantastic for your gardens, trees, and shrubs. Not only does it give your property a beautiful and manicured look, but it also adds protection to your plants. It helps your soil retain moisture and regulates temperature changes by insulating. It also blocks weeds from sprouting and taking over your garden. Some products are even made from organic materials that break down and add nutrients to your soil!

The Right and Wrong Way to Mulch

Although there are many awesome benefits, it is vital to know the correct way to mulch, or else you can do more damage than good.

Preventing Harm to Trees

When a tree is “volcano mulched”, meaning it is piled high up on the trunk of the tree, the roots mistake the mulch for soil and grow in the wrong direction. This causes Girdling Roots. As roots grow up and around the trunk, they can strangle the tree over time as the trunk grows thicker! You or your landscaper should always leave at least a 1” space around the tree trunk with nothing touching it.

Preventing Damage to Lawns

Proper edging around garden areas is very important as it helps to keep everything in the beds. If you or your landscaper don’t edge, mulch can run off on to the grass when it rains. In the same way it prevents weed growth, it can smother and kill your grass! A clean edge will prevent runoff and keep your grass alive and well.
