Why is My Tree Dropping Leaves in May? All About Anthracnose

The scene can be shocking. In the midst of spring, right when your tree canopies should be getting lush, you notice leaves littering your lawn.

The problem? It could be anthracnose, a group of fungal diseases. While this seasonal dilemma is more of an annoyance than a serious issue, Premier Tree Solutions can provide suggestions on how to pinpoint anthracnose and stop it in its tracks.

What is Anthracnose?

The North Carolina State Extension explains how cool and rainy spring weather is the prime condition for anthracnose. The fungi endures and survives winter in places such as diseased buds, plant debris, fallen leaves, and twigs. Come spring time, they produce and release spores, and the wind and splashing rain allow the spores to spread to trees. If the chilly and wet weather continues, spores can form within the leaves of an infected tree and spread all over its canopy.

According to the University of Minnesota Extension, anthracnose can cause a variety of tree troubles, including premature leaf drop, dark spots on leaves, cupping or curling of leaves, and blisters or banding on young branches.

Can Anthracnose Kill My Tree?

Anthracnose symptoms may look dramatically nasty, but its bark is worse than its bite. The good news is anthracnose rarely causes serious damage or death to healthy, established trees. In fact, it’s usually a temporary problem heavy on unappealing aesthetics.

Since the spring weather helps drive the disease, a warm and dry summer calms the storm. Once mid-summer rolls around, trees typically push out a fresh, healthy flush of leaves.

How to Manage Anthracnose

While the problem can go away on its own, you can take steps to manage the issue and lessen the risk of it happening again.

Throughout the growing season, reduce stresses on trees by properly watering them. The University of Georgia Extension suggests making sure trees get the right amount of hydration, not too much or too little. Follow Premier Tree Solutions’ guide to watering trees. However, keep in mind that wet conditions can promote anthracnose, so redirect sprinklers that could potentially splash water on the tree’s leaves.

Make sure and rake up and destroy fallen leaves, which helps stop the fungus from surviving and invading trees the following spring.

Careful pruning can be helpful. First, make sure and remove any infected twigs. Strategic pruning improves light penetration and air circulation throughout the canopy. Thinning the foliage allows an increase in wind movement and lessens leaf moisture, which decreases the likelihood of anthracnose.

When to Get Professional Help with Anthracnose

While the problem often resolves on its own, it helps to get expert assistance. If a tree doesn’t refoliate or if an anthracnose infection takes place a few years in a row, you should definitely consult a professional. No matter what, it’s always best to play it safe when it comes to fungal diseases such as anthracnose. Call Premier Tree Solutions at 404-252-6448 or schedule a complimentary assessment online.

The Invasion Check: Protecting Your Maples and Oaks from 2026’s Top Pests

Georgia has a strong reputation for its gorgeous tree canopies. Oak trees, with their sprawling, regal crowns, and lush maples, boasting vibrant red, yellow, and orange foliage, are both iconic varieties among the state’s treasured flora. And countless homeowners display them with pride.

However, early 2026 has seen an increase in invasive pests moving throughout the Southeast, threatening the livelihood of these trees. To help protect your prized timber from pesky invaders, Premier Tree Solutions offers the following tips and which critters to look out for this season.

The Big Three Threats to Maples and Oaks

According to experts, a trio of pests are arguably rising to the top as being the most troublesome in the Southeast.

Asian Longhorned Beetle

According to Clemson University, South Carolina is currently experiencing an Asian longhorned beetle infestation. With its close proximity, this issue could potentially move its way into Georgia. These insects are problematic for hardwoods, especially maple trees. The U.S. Department of Agriculture (USDA) explains that Asian longhorned beetles attack and kill trees by growing inside them and feeding on the living tissues that carry nutrients. Infested trees become hollowed out and are unable to heal, which can increase the risk of a fall.

These creatures are approximately the size of an almond, and have black and white antennae, which are longer than the insect’s body. Their bodies are shiny and black with white spots, and they have six legs and bluish-colored feet.

Evidence of Asian longhorned beetles include round exit holes in tree trunks and branches, measuring as large as the size of a dime. Look for oval-shaped egg sites or round wounds chewed into the bark. At the base of the tree, you may see sawdust-like material. If you expect an infestation in a tree, contact Premier Tree Solutions immediately.

Spotted Lanternfly

Don’t be charmed by this invader’s jumbo, eye-catching wings. The brown forewings feature black spots, while its hind wings are deep red with black spots, and black and white stripes. Spotted lanternflies have yellow abdomens with black bars. They’re approximately one inch in length.

Colorful looks aside, these insects continue to cause trouble in the Peach State. After detecting them in 2024, the Georgia Department of Agriculture is now identifying them as a major statewide threat in 2026. The PennState Extension reports that while spotted lanternflies do not generally kill healthy, established hardwood trees, they drain vital nutrients from trees, including maple, which can cause branch dieback and plant health decline.

According to the USDA, when feeding, they excrete a sticky, sugary liquid called honeydew, which has a vinegar-like smell. The residue encourages the growth of sooty mold, which blocks sunlight and can lead to additional damage. Spotted lanternflies are typically found in large groups when feeding. Be on the lookout for egg masses that resemble smears of gray mud.

Spongy Moth

In the late spring, you might find huge clusters of fuzzy caterpillars gathering on trees, including oak. That could be a sign of a spongy moth infestation. Although they’re usually found in the Northeast, Midwest, and Appalachian regions, spongy moths are now considered a serious potential threat to our forests by the Georgia Invasive Species Task Force.

Spongy moths are known to defoliate entire forests. The USDA says a heavily infested forest can have a barren, wintry look even during peak summer.  If untreated over multiple seasons, spongy moths not only strip leaves, but can kill trees. Persistent defoliation can weaken even the sturdiest of oak trees, opening the door to secondary diseases such as root rot.
