How to add interest to your garden beds
Angle. Think about how the bed looks from different parts of the garden ― from paths, patios, or other gathering places, or from living room windows. Angle the bed for best viewing from one or more of those locations.
Shape. A bed in the shape of a circle, square, or octagon looks formal, while one with a free-form shape has a casual look. Experiment by laying a hose on the ground and adjusting its curves.
Height. To add visual interest to a level bed, mound soil in the center or at one end to create a gentle berm ― an elevated stage for an art object or accent plant.
