Delicious citrus: Scott Bauer, USDA Agricultural Research Service
It’s time to grab those gloves and get outside for some gardening! April is not only a great time to plant citrus trees, but it’s also Invasive Plant Pest and Disease Awareness Month. Before wielding that shovel, take a few minutes to learn how to keep your trees healthy and prevent the spread of citrus disease.
Citrus greening disease, also known as Huanglongbing (HLB), is one of the most severe plant diseases in the world. The disease has devastated millions of citrus trees in the United States and now has the potential to eliminate the citrus industry. Once a tree is infected with the disease, there is no known cure.

Agricultural items in passenger baggage: R. Anson Eaglin, USDA Animal and Plant Health Inspection Service
Travel is a popular activity for a lot of people. When traveling outside the United States, what you bring back really does matter. We want to protect our country from invasive plant pests and diseases to help keep our agriculture and forests safe.
You don’t want to inadvertently bring a pest or disease back with you. That’s why Customs officials ask you to declare any food, plant items or handicrafts you have with you when you are returning to the U.S. They know what items pose a risk and need to be kept out of the country. Many of those items are things you may not think could possibly cause a problem, but they could cause severe problems here at home—who wants that? Read more »
Mexican fruit flies on citrus fruit: Jack Dykinga, USDA Agricultural Research Service, Bugwood.org
USDA has proclaimed April to be Invasive Plant Pest and Disease Awareness Month, so this is the perfect time to consider how invasive species can crawl, swarm or ooze their way into your daily life. The fact is, invasive pests and diseases hunger for many of the same things we enjoy each day. And as they feast on America’s agricultural and natural resources, they can devastate crops and forests, throw ecosystems out of balance and lead to lost jobs and closed export markets. Read more »
Volunteers help harvest native seedlings at the Hiawatha National Forest greenhouse in Marquette, Mich. U.S. Forest Service photo.
Biologists have long recognized the important role native plants play in maintaining a healthy forest. When native plants are crowded out by invasive plants, those native species can suffer to the point of extinction.
Since the early 1990s, the Hiawatha National Forest has operated a greenhouse in Marquette, Mich. The idea is to provide both native seeds and seedlings for successful restoration of sites impacted by logging or disturbed by other land management activities. For instance, when aging culverts are replaced, native plants can be introduced to re-vegetate disturbed soil. Seeds and seedlings are also used to enhance existing wildlife habitats. Read more »
