One of the great things about gardening is everyone can incorporate their own styles by selecting plants and features they enjoy. However, there are some common mistakes in the landscape everyone should avoid so that they can dodge future problems and keep their plants healthy.
Here would be my “Top 5” common landscape mistakes (in no particular order):
- Volcano mulching: Mulch provides many benefits such as reducing weeds and conserving soil moisture. A common mistake that occurs is when mulch is piled up around tree trunks — an error known as volcano mulching. This pile of mulch can cause damage to the tree trunk by holding moisture which can create insect and disease problems along with bark decay. A good layer of mulch should be 2 to 4 inches deep. The mulch should be pulled 1 to 2 inches away from the base so that you can see the base of the tree trunk.
- Right plant, right place: Instead of haphazardly placing plants anywhere in a landscape, it will pay off to first do some research on plants you are interested in.
