How You Can Help Monarch Butterflies in Nassau County

Monarch butterflies are more than just a pretty sight in our gardens—they’re important pollinators that help keep our environment healthy. Unfortunately, Monarch populations are in trouble, and we need to act now to protect them. With their numbers declining and the possibility of them being listed as a threatened species, it’s a great time to take simple steps to help them thrive.

Why Monarchs Need Milkweed

Monarch butterflies are famous for their long migration from Canada to Mexico. But their journey begins right here in Florida, where they lay their eggs on milkweed plants. Milkweed is the only plant Monarch caterpillars can eat, making it essential for their survival. But there’s a problem: not all milkweed is good for Monarchs.

One variety of milkweed, Tropical Milkweed, has become a big issue for Monarchs. While this plant is often sold in stores and planted in gardens, it doesn’t die back in the winter like native milkweeds do. Because of this, Monarchs don’t migrate when they should, and some fall victim to the cold. Tropical Milkweed also encourages the growth of a harmful parasite that damages Monarchs, further threatening their population.

What You Can Do to Help Monarchs

You can make a big difference in helping Monarchs right in your own backyard. Here’s how:

1. Remove Tropical Milkweed: If you have Tropical Milkweed in your garden, the best thing you can do is remove it. If that’s not possible, you can cut it back in the cooler months to help reduce the harmful parasite. Here’s more information on how to identify Tropical Milkweed.
2. Plant Native Milkweed: Florida has 21 native species of milkweed, and they’re the best choice for Monarchs. Try planting Butterfly Weed (Asclepias tuberosa), a native species that loves full sun. Find out more about native milkweed options here.
3. Follow Florida-Friendly Landscaping Principles: The Florida-Friendly Landscaping™ program offers great tips for creating landscapes that help wildlife, including Monarch butterflies. The 5th Principle—“Attract Wildlife”—is all about planting the right plants that provide food and shelter for local wildlife. Learn more about Florida-Friendly Landscaping™.
4. Share the Word: Talk to your neighbors, schools, and community groups about Monarchs and other pollinators. Sharing what you’ve learned can inspire others to make small changes that will add up to a big impact. Consider starting your own pollinator garden!

How UF/IFAS Extension Nassau County Is Helping

At UF/IFAS Extension Nassau County, we’re working hard to help our community protect Monarch butterflies and other pollinators. We’ve partnered with local nurseries to encourage the sale of native milkweed and offer educational programs on how to create pollinator-friendly landscapes.

We’re also collaborating with homeowners’ associations (HOAs) to update landscaping guidelines that support wildlife, including Monarchs. One fun initiative we’re launching this year is “No Mow March,” which encourages homeowners to let wildflowers grow on their properties to provide more food for pollinators.

Challenges and How We Can Overcome Them

While removing Tropical Milkweed and planting native species is a great start, there are still challenges to face. Tropical Milkweed is widely available in stores, and it’s also spreading into natural areas, which makes it harder to manage. But with continued education and action, we can help turn the tide for Monarchs.

Let’s Make a Difference Together

By removing Tropical Milkweed, planting native milkweed, and following sustainable landscaping practices, you can help Monarch butterflies and other pollinators thrive in Nassau County. These small changes will make a big impact on the health of our local ecosystem.
