Garden dividers are a great way to add structure and definition to any outdoor space. BEDS, with four letters, are a popular choice for garden dividers as they can be used to create a variety of shapes and sizes. Hedges, with six letters, are also a popular choice for garden dividers as they provide a natural barrier and can be easily shaped to fit the desired area. Both BEDS and hedges can be used to create a beautiful and functional garden divider.
