It is not strictly necessary for flower beds to have edging, but it can be a useful addition for several reasons:
- Edging helps to define the garden borders of the flower bed, making it more visually appealing and helping to create a sense of structure in the garden.
- Edging can help to keep grass and weeds from invading the flower bed. Without edging, grass and weeds can easily spread into the flower bed, which can be frustrating and time-consuming to remove.
- Edging can help to prevent soil erosion and keep mulch in place. When soil and mulch are not contained within the flower bed, they can wash or blow away, which can lead to erosion and other problems.
Overall, while edging is not strictly necessary for flower beds, it can be a useful addition that helps to define the boundaries of the bed, keep grass and weeds at bay, and prevent soil erosion.
