Growing a small oxydendrum, commonly known as a sourwood tree, in an outdoor plant box is possible with the right conditions. This elegant tree, prized for its vibrant fall foliage and delicate summer flowers, can thrive in containers if given proper care.

To succeed, choose a spacious plant box with good drainage, as oxydendrum prefers moist but well-drained soil. Use a slightly acidic potting mix to mimic its natural woodland habitat. Position the box in a spot with full sun to partial shade, ensuring at least 4-6 hours of sunlight daily.

Regular watering is crucial, especially during dry spells, but avoid waterlogging. A layer of mulch helps retain moisture and regulate soil temperature. Prune lightly to maintain shape and remove dead branches.

While oxydendrum grows slowly, it may eventually outgrow the box, requiring transplantation to a larger container or garden bed. With attention to these details, you can enjoy this stunning tree in your outdoor space.
