What month do you cut back perennials?

Answered by Tom Adger

When it comes to pruning perennials, the timing can vary depending on the specific plant. Generally, the best time to cut back perennials is in either late fall or early spring. However, it’s important to consider the specific needs of each plant before taking out those pruning shears.

For perennials like hostas, peonies, and daylilies, it is recommended to prune them in late fall after the first few frosts. This timing allows the plants to go dormant and prepares them for the winter season. By cutting them back after the frosts, you can avoid any potential winter damage that may occur. I personally remember pruning my hostas in late fall last year, and they came back beautifully in the spring with fresh, healthy foliage.

On the other hand, some perennials, such as mums and coneflowers, are better off being pruned in spring, just before new growth begins. This timing enables the plants to benefit from the winter protection provided by their dried stems and foliage. Pruning them in early spring allows you to remove any dead or damaged parts, promoting healthy new growth for the upcoming season. Last spring, I pruned my mums and coneflowers, and they rewarded me with vibrant blooms later on.

It’s worth noting that not all perennials require heavy pruning. Some may only need light maintenance, such as deadheading spent flowers or removing any unsightly foliage throughout the growing season. This light pruning can be done as needed, regardless of the season, to keep the plants looking tidy and encourage continuous blooming.

To summarize, the month to cut back perennials can vary depending on the specific plant. For perennials like hostas, peonies, and daylilies, late fall or early winter after the first few frosts is the ideal time. On the other hand, perennials like mums and coneflowers are best pruned in early spring, just before new growth emerges. Remember to consider the individual needs of each plant and adjust your pruning schedule accordingly. Happy pruning!
