One of the most common questions I’m asked this time of year is “when do I cut back my perennials?”
The answer is really up to you; it makes no difference to the plants. Some gardeners cut their perennials back in fall, after they’ve been frosted and don’t look so good anymore. This gives you a really tidy-looking winter landscape.
Other gardeners prefer to wait until spring so that the perennials catch snow and create winter interest. In fact, some perennials such as purple coneflower and black-eyed Susan, have seeds that will attract birds to your fall and winter garden.
As for me, I tend to leave my plants stand until spring. I’m usually busier in fall — and it gives me a reminder of where everything is planted before it starts growing for the year.
