Hello,

From this single image, I identified this tree as an American Sycamore (Platanus occidentalis) species of Plane trees

Caring for an American Sycamore (Platanus occidentalis) tree, especially during heat stress, involves several key steps to ensure its health and growth. Here are some tips based on expert advice from educational sources:

Watering: It’s crucial to water the tree immediately after planting and once a week if it’s dry. After a month, the tree will be established, and watering will only need to occur during very dry periods. The tree is surprisingly drought-tolerant when established. More information at this link:

Soil Conditions: American Sycamore prefers deep, moist, rich soils but can grow in marginal soil with low oxygen and high pH2. Ensure the tree is planted in good drainage to prevent waterlogging. More information is at this link:

Sunlight: This tree species prefers full sun or light shade locations. Make sure your tree is not overshadowed by larger structures or trees that could limit its sunlight exposure.

Pruning: Prune drooping branches on trees near vehicular or pedestrian traffic to avoid accidents. Also, the occasional double leader should be eliminated to promote a single, strong trunk. More information is at this link:

Monitoring for Diseases: The species is prone to anthracnose, a common fungal disease that can stunt and abort leaf production in moist springs. While it is primarily a cosmetic issue, it’s crucial to monitor the tree’s health and consult a local arborist if you notice any signs of disease.

Wildlife Benefits: The tree provides food for small mammals and songbirds, so maintaining its health also supports local biodiversity. More information is at this link:

Each tree is unique, and local conditions such as soil type and weather patterns can affect its health. Test Soil: Have a soil test to check for pH and nutrient imbalances. Details on soil testing are at this link:

If you continue to see signs of distress, consider contacting the MSU Plant and Pest Diagnostics or a certified arborist for personalized advice. They can provide specific guidance based on the tree’s condition and your local environment. See the two options.

OPTION 1:

For a confirmed and precise identification of the problem, I recommend you send all your images by e-mail to the MSU Plant & Pest Diagnostics Lab. The experts there can also provide you with the best treatment options. Their email is <personal data hidden>. Please include your name. The lab will let you know if they need a sample sent. FYI, the lab may also ask for additional images.
