Hemlock doing his part to help fight invasive plants! That pretty white plant you see EVERYWHERE has a surprising name and a shocking effect…

🧄 What’s in a name?: Meet “Garlic Mustard”

🌱 Toxic relationship: It releases harmful chemicals into the ground, disrupting the soil microbial community that our native plants depend on.

👿 It’s a bully: Aggressively crowding out our native wildflowers that need to be here to feed beloved local wildlife.

🎲 It’s playing the long game: Garlic Mustard is blocking tree seedlings, like oak, at this very moment, from ever getting established.

🚫 Persona non grata: It’s actually a prohibited species in New York State, so if you spot it, pull it up and trash it (not compost!).

🖐️ Weak roots: It’s satisfyingly easy to pull up and clear within a few minutes.

🍃 Meet Helmock: Hemlock is a non-releasable North American porcupine. While porcupines are not native to Westchester, they are native to NY state. Porcupines are stict herbivores depending on native trees and vegetation.

📱 Follow for more tips on easy and impactful ways to support local!

👟 Open to the public dawn - dusk.

Challenge 3 inspiration for the Less Lawn More Life challenge, hosted by Rebecca McMackin, Ecological Horticulturalist & Garden Designer at , followed by member Austin as he shows you how to prepare your planting spot.

🌱 This week’s challenge: plant some natives. You’ve picked your spot. Now it’s time to get something in the ground.

🌱 Here’s how to make it happen:

Figure out your ecoregion’s plants. There are books, websites, and the free Wildr app to help you find what belongs where you live. Start there.

Find your plants. Local nurseries and online retailers carry natives, but plants can also be free! Ask neighbors, friends, or your local native plant society. Someone nearby probably has more than they need.

Get them in the ground.

Native plants aren’t just pretty; they evolved alongside the birds, bees, and butterflies in your region, and those relationships are breaking down. Every plant you add helps knit that web back together.

It’s free, and it’s not too late to sign up at LessLawnMoreLife.com.

Challenge 2 inspiration for the Less Lawn More Life challenge, hosted by Jess Zander, Garden Coach of , followed by team member Jessie as she picks her spot.

🌱 This week’s challenge: pick your spot. Choose one small patch, just 5 ft x 5 ft, that you’re going to fill with native plants. Don’t worry about what to plant yet — that’s next week.

🌱 Here’s how to pick the right one:

Pick a high-impact location. Choose somewhere you can see from a window or walk by every day. You’re going to want to watch it change.

The best spot is one that’s already asking for it: where your lawn struggles to grow, under a tree where leaf litter is doing half the work, or an existing bed you’re ready to rewild. Balcony? A container works too.

Assess your conditions. Roughly estimate how much sun the spot gets: full sun (6+ hours), partial sun (3–6 hours), or shade (under 3 hours). Notice if it stays wet or dry after rain. This will matter when you choose plants.

Start small. A 5x5 patch is easy to maintain and can still pack a real ecological punch.

It’s free, and it’s not too late to sign up at lesslawnmorelife.com.
