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.

Ready, set, hike! With football season upon us, we want to help you “kick off” your citrus’ health. Whether you are a rookie or seasoned veteran when it comes to growing fruit, following these simple tips can help your citrus have a winning season.

Celebrate the Red, White, Blue and Orange

Take time to stop and enjoy a glass.

Make this Fourth of July a celebration of citrus’ role in this holiday’s food and culture. My hope is to raise awareness of the serious threat that diseases like citrus greening pose to U.S. citrus so Americans can protect the refreshing flavors of summer. Read more »

Make Cinco de Mayo a “Citrus de Mayo” Celebration

This year I am encouraging everyone to make the Cinco de Mayo celebration a “Citrus de Mayo” affair by celebrating citrus’ role in the holiday’s food and culture.  My goal is to raise awareness of the serious threat that diseases like citrus greening pose to United States citrus.

From the limes and oranges we use to marinate the carne asada, and the lime we squeeze over our guacamole and tacos to bring out the flavor, to the delicious margaritas and the lime wedges with which we top an ice-cold beer, citrus is at the center of the festive Cinco de Mayo event.

Cinco de Mayo is just not the same without citrus.  With multiple diseases affecting our citrus and the recent confirmation of citrus greening disease in California, our access to U.S.-grown citrus is under serious threat, and with it, many of the foods and festivities we enjoy. Read more »
