Is there evidence that reduced mowing helps pollinators?

The general consensus among researchers is that mowing every 2 or 3 weeks is best for pollinators. A 2018 study from the journal Biological Conservation tested several mowing frequencies in suburban spaces as they relate to pollinators, which found that mowing every two weeks may be more beneficial than a total month-long reprieve, as insects have a more difficult time finding flowers surrounded by tall grass. Mowing once every two weeks is considered a “happy medium” where flowers can establish and are still accessible to pollinators.

Additionally, it's also important to ensure that you are mowing your lawn properly to prevent harm to pollinators. This includes mowing at a higher height, using a sharp blade, and avoiding mowing during times when pollinators are most active, such as early morning or late evening.
