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.
