Winter Maintenance: Daylilies

Asked September 24, 2013, 1:21 PM EDT

I was curious when I should trim our daylilies for the winter? We are in the Greeley area. Please advise!

Daylilies increase in size yearly, and may need to be divided every three to four years. This task is easier to accomplish before the individual clumps become too large and difficult to handle. After the plant is done blooming (this will vary from early August until late September on the Colorado Front Range and depending on the cultivar) you can simply cut back the foliage to about 8 inches with a pair of hedge shears. Division can be done in the spring as new growth emerges, or late in the summer after flowering. Make sure that your shovel is sharp.
