Why is it important to prune the base wider than the top for hedges?

Pruning hedges with a base wider than the top is essential for maintaining fullness and aesthetic appeal, which contributes to the overall health and appearance of the hedge. When hedges are pruned in this manner, it allows sunlight to penetrate the lower branches more effectively, promoting healthy growth throughout the entire plant. In this way, the lower foliage receives adequate light, preventing it from becoming sparse or bare. Additionally, this shape can optimize air circulation within the hedge, reducing the likelihood of disease and enhancing the plant's vigor.

Furthermore, a wider base leads to a natural tapering effect that can help create a more visually pleasing silhouette, which is often desired in landscape design. This design consideration is particularly important for ornamental hedges, as it enhances their sculptural qualities and overall integration into the landscape. Therefore, the emphasis on maintaining fullness and aesthetic appeal is pivotal in the practice of hedge management.
