When should plants be pruned?

It is essential to refrain from pruning during the fall season, as doing so may disrupt the plants' natural preparation for the upcoming winter. Most plants can be carefully trimmed and shaped in early spring to effectively reduce plant stress and minimize the risk of diseases, ensuring the optimal development of the vegetation.

Additionally, it is recommended to leave herbaceous perennials undisturbed during the winter months, however, light tidying and trimming is acceptable. It's completely fine to trim a plant that has drooped over a sidewalk, obstructing the passage, or one that has turned black and become soft due to damage or disease. Perennial plant material in the winter, due to its role in providing shelter, plays a crucial part in maintaining the balance of the ecosystem. The Xerces Society emphasizes that nearly 30% of native bees rely on the narrow tunnels present in hollow stems of perennial plants for nesting and survival, showcasing the vital significance of winter plant remnants in supporting various species. For this reason, pruning is best postponed until early spring, just prior to the onset of new growth. This approach not only supports the plants' resilience but also preserves their intended locations during the winter, facilitating an organized and well-planned garden landscape.

As for the flowering perennials during the summer, it is advisable to wait until their blossoms have withered before pruning, thereby promoting their healthy growth. Pruning after flowering can also encourage a second bloom later in the season. Regular pruning not only helps maintain a tidy appearance but also promotes the overall health and vitality of the vegetation in your garden or outdoor space.

Prune young trees 3-5 years after planting to help them grow strong against wind. Remove up to 20% of the tree at a time, focusing on eliminating double leaders and identifying the central leader. Pruning may take years, but it promotes long-term tree health.

Pruned material can be relocated to a designated area on your property for yard waste such as a compost bin but it should not be sent to a landfill.
