Why Prune Perennials in August?
Pruning perennials in August offers several benefits. It encourages new growth before the end of the growing season, helps control plant size, and removes dead or diseased foliage. Additionally, pruning can improve air circulation and reduce pest problems, leading to healthier plants come fall and spring.

The best time to prune perennials in August depends on the plant species and your local climate. Generally, late summer, about 6-8 weeks before the first expected frost, is ideal. This timing allows plants to recover and prepare for the upcoming colder months.
