Trees are a huge asset to the landscape. Did you know that according to research, just three properly placed trees can save between $100 and $250 per year in energy costs? Whether you have just planted new trees or have large majestic trees, they can become the targets of disease, insects and human error that can slow their growth and even kill them. This article will cover several tree troubles to be on the lookout for in the next few weeks.
First, I want to address mulching. Unfortunately, as I drive around our communities, I continue to see what is known as the “mulch volcano.” This is the practice of piling mulch high up the trunk of a tree and sloping it down towards the ground — like the shape of a volcano!
When mulch is applied in this manner, it is very detrimental to the tree. It confuses the tree to thinking that the soil level has changed. This will cause the tree to start growing roots into the mulch and can even start to cause decay in the trunk. Mulch applied too deeply can actually prevent moisture from reaching the soil and suffocate the roots — causing the tree to die.
