American sycamore

American sycamore (Platanus occidentalis) plants require moderate amounts of watering. Each year, the frequency of watering will vary based on the climate and the stage of growth the plant is at. During the spring and summer months, when the plant is actively growing, young trees should be watered about 2-3 times a week, while mature trees should be watered about 1-2 times a week. During the fall and winter months, watering should be reduced to about 1-2 times a month, as the plant goes dormant. When watering, thoroughly saturate the soil to make sure all of the roots receive adequate moisture. Additionally, always test the soil to ensure that it is not oversaturated or too dry before watering.

American sycamore plants need a minimum of 6 to 8 hours of full sun exposure per day, preferably during the middle of the day when the light is brightest. Additionally, their ideal light is direct sunlight, meaning sunlight that is not filtered by a shade tree or other structure. While a few hours of shade won’t harm the plants in any noticeable way in the short-term, the plants may struggle long-term if they don’t get enough full sun exposure. For maximum growth and vitality, American sycamores should receive full sunshine.

American Sycamore trees should be pruned in late fall or early winter while the tree is dormant. Pruning should concentrate on the removal of dead, dying, or diseased wood, crossed branches, and water sprouts to improve the overall health and shape of the tree. All pruning cuts should be made cleanly and flush with the branch collar. Prune branches back to the main trunk, or leave a few buds on the branch to encourage branching. When pruning larger branches, it is recommended to use a 3-cut method to avoid ripping the bark. It is best to only lightly prune mature trees and only when necessary.
