Prepare your perennials for winter

September 25th, 2020

In northern Colorado and along the front range, ‘winter’ can hit at different times every year. Although this year we’ve already had a little bit of snow, warm temperatures are already returning. Before we enter a full-on cold season, though, there are a few steps you’ll want to take to prepare your perennials.

Perennials are plants and grasses that continue to grow year after year. They will go dormant during the winter, but there are ways to help them survive the cold and ensure they’ll grow back bigger, stronger, and brighter next spring!

Winter Watering

Winter watering is important! Your trees will need to be watered throughout the wintertime, and your perennials can be watered until the ground freezes.


Covering the beds and roots of your perennials will protect them during the cold winter and works as an insulation. You can use hay, evergreen boughs, wood mulch, or shredded leaves as mulch. This especially applies to newly planted perennials.


If your perennials have finished for the season, the stems should be cut back to about 6-8 inches from the ground. This is usually after the first few frosts.


About fertilizing in the fall … don’t do it on your perennials! This encourages new growth, so save it for the springtime.


It’s a good idea to get out as many weeds as you can before the winter and the ground freezes. This will prevent the spread of weeds in the springtime! This is also a good time to clean up any debris in your yard. If there were disease or bug infested plants in your garden, get rid of them!
