What is a common reason to prune plants to maintain a geometric shape?

Pruning plants to maintain a geometric shape serves multiple purposes, with one of the primary reasons being to stimulate new growth and enhance aesthetics. When plants are pruned to a specific geometric shape, it encourages healthy growth patterns and can promote denser foliage by allowing more light to reach the interior of the plant. This shape maintenance not only improves the overall appearance, making the landscape more visually appealing, but also helps manage the growth of the plant in a way that aligns with design intentions.

By focusing on aesthetics, pruning also allows for a more structured garden space, which can be particularly important in formal landscapes. Furthermore, this practice can lead to better air circulation and light penetration within the plant, promoting overall health and vigor. In contrast, while access, drainage, and sunlight exposure are important in horticulture, they are not the primary reasons for maintaining a geometric shape through pruning.
