Sawflies: A Truly Weird Garden Pest | You Bet Your Garden

May 22, 202656 minSummary

In this episode of You Bet Your Garden, host Mike McGrath tackles a variety of horticultural challenges, ranging from misunderstood garden pests to lawn management strategies. The show begins with a discussion on the rise and fall of the No Mow May movement in the United States. McGrath notes that while the concept originated in the UK to support native meadows, it is often less effective in the U.S. due to different climate patterns and the prevalence of non-native lawn species. Instead, he advocates for "slow mow" practices, such as raising mower blades and extending intervals between cuts to better support pollinators. A significant portion of the episode is dedicated to the sawfly, a garden pest that often stumps gardeners because it mimics the appearance of a caterpillar despite being a completely different insect. McGrath provides listeners with tips on how to identify these "plant munchers" and effectively manage them. Additionally, the host answers listener questions regarding tomato blossom end rot—emphasizing the importance of calcium and organic fertilizers—the benefits of using rabbit droppings as a soil amendment, and the parasitic nature of mistletoe in stressed urban trees.
