Thinking about No-Mow May? Here’s what you should know.

Letting the lawn grow in May can offer short-term support for bees and other pollinators, but the bigger benefit comes from how we manage our landscapes all season long. 🐝🦋

A few simple ways to create better habitat beyond May:

Mow less often: Consider mowing every other week.

Leave a small section of your yard unmown all season.

Eliminate chemicals.

Reduce the lights: Outdoor lights impact bird migration and prevent fireflies from seeing each other’s flashes.

Clean up less: Fewer clean-ups provide food and shelter for all kinds of creatures.

Good stewardship provides much-needed habitat for pollinators, insects, birds, amphibians and other animals, while rewarding us with more biodiversity in our own yards.

🦋 Ever wonder how the butterflies you see in New Hampshire compare to those in other places?

Join us for "Across Regions & Seasons: Comparing the Butterflies of New Hampshire and Texas” on April 22 (4:00–5:15 PM, online)!

Discover how species overlap across regions, which ones look alike (but aren’t!), and how geography shapes the butterflies we see throughout the year. With over 750 butterfly species in the U.S., you might be surprised how connected our local sightings are to places far beyond New England.

Whether you're a seasoned butterfly enthusiast or just curious, this engaging webinar is for you — no experience needed.

The first 2,000 donors who make a gift with the numbers 6, 0, 3 in any order (and who have not already given during The (603) Challenge) will have $20 added to their gift. This means, a gift of $3.06 or $603 all earn the same bonus!

If we reach 450 donors, Branch Hill Farm and an anonymous donor will give Extension $20,000! https://give.unh.edu/.../the-603.../pages/unh-extension

If the 4-H Foundation of NH gift fund receives 100 donors in the next 2 days, Ed McAllister (our former assistant director) will give an additional $2,500! https://give.unh.edu/schools/UniversityofNewHampshire/the-603-challenge-2026/pages/4-h-foundation-of-new-hampshire
