What is the ideal shape for pruning hedges?

The ideal shape for pruning hedges is wider at the base than at the top. This design supports the natural growth habit of most plants and ensures that the lower branches receive adequate sunlight. When the base is wider, the foliage at the bottom can thrive and maintain fullness, preventing the hedge from becoming bare or unattractive as it matures. Additionally, this shape aids in water drainage and reduces the likelihood of disease by allowing better air circulation throughout the plant.

A uniform width throughout can lead to shading of the lower branches, which may cause them to die off and detract from the overall health and appearance of the hedge. Meanwhile, a tapered top is often suggested for aesthetic reasons, but it may not provide the best support for healthy growth if the taper is excessive. A flat top can appear boxy and does not account for the natural taper of plant growth, which can make the hedge look less natural and healthily structured.
