Perennials have distinct growth cycles that influence when and how they should be pruned. Most perennials experience a period of rapid growth in the spring, followed by blooming. After this initial bloom, many perennials enter a phase of slower growth, making it an ideal time for pruning.

Understanding these cycles is crucial for effective pruning. By cutting back perennials after their first bloom, gardeners can encourage a second flowering period. This not only extends the blooming season but also helps maintain the plant’s vigor and health. Additionally, understanding the growth habits of specific perennials can help gardeners tailor their pruning techniques to each plant’s needs.

Coreopsis, known for its bright, daisy-like flowers, benefits greatly from a June pruning. By cutting back spent blooms and about one-third of the plant’s height, gardeners can encourage a longer blooming period. This practice stimulates the plant to produce new flower buds, resulting in a more extended display of color.

In addition to promoting more blooms, cutting back Coreopsis helps maintain a tidy appearance. This is particularly important for taller varieties, which can become leggy and unruly if left unpruned. Regular pruning also helps prevent the plant from self-seeding excessively, which can lead to overcrowding in the garden.

Salvia, with its vibrant spikes of flowers, is a favorite among gardeners and pollinators alike. To encourage a second flowering, it’s important to cut back Salvia after the first flush of blooms has faded. This involves removing spent flower spikes and trimming back the plant by about one-third.

This practice not only promotes a second round of blooms but also helps maintain the plant’s shape and size. By preventing the plant from becoming too woody or overgrown, gardeners can ensure that Salvia remains a focal point in the garden throughout the summer months.

Catmint, known for its aromatic foliage and lavender-blue flowers, can quickly become unruly if not pruned regularly. In June, after the first flush of blooms, it’s beneficial to cut back Catmint by about half. This encourages a more compact growth habit and a second wave of flowering.

Pruning Catmint also helps prevent the plant from flopping over, which can occur when stems become too long and heavy. By maintaining a tidy appearance, gardeners can enjoy the beauty and fragrance of Catmint without it overwhelming the garden space.
