To mow or not to mow? What science says about early season lawn care

One of the most definitive signs that spring has arrived is the sound of lawnmowers filling the neighborhood. But this month, that rumble may be a little quieter than usual. That's because of a recent trend in yard care called "No Mow May." 

The idea is simple: wait until June to mow to allow flowers like dandelions and clover to grow and support bees, butterflies, and other pollinators.

The concept was started in 2019 by Plantlife, a UK-based conservation organization, in response to declines in pollinators and their natural habitat. It's since become a popular movement among some gardeners and conservation advocates in the U.S. – propelled, perhaps, by the catchy name and the #NoMowMay social media hashtag.

But is it a good idea for our region?

Before you decide whether to break out your lawnmower this weekend – or leave it idle – we asked for advice from our friends at Plant Talk Colorado at CSU. Extension professor of horticulture Alison O’Connor joined us to explain whether No May May is backed up by science.
