Black gum is a deciduous shade tree that thrives in full sun to partial shade and prefers moist, well-drained acidic soils. Due to its slow growth, careful consideration should be given to its planting location, as it can be challenging to transplant. This tree is well-suited for naturalized settings, lawns, streetscapes, or low-lying areas of the yard, as it tolerates wet conditions effectively. It naturally occurs in flooded swamps, pinelands, and pocosins. Primarily dioecious, male black gum trees play a crucial role in facilitating fruit production in female trees. In the fall, this species showcases a stunning red foliage.

Regarding pests and diseases, black gum generally faces no significant issues. It is heat-tolerant, although it may occasionally attract leaf miners and scale insects. Stressed trees can be susceptible to cankers, leaf spots, and rust.
