Care
Sourwood trees thrive in well-drained, acidic soil. They prefer consistent moisture, especially during dry periods. Trim in winter to preserve shape and remove dead or diseased wood. Mulch to retain moisture and protect roots. They’re generally pest-resistant.

Plant Reproduction
Sourwood Tree spreads via seeds dispersed by wind and gravity.
Plant bare root trees during the dormant season in early spring or late fall (November through April). Dig the hole twice as wide as the roots so the soil is well-drained. Position the tree so the root flare is at or just above ground level. Fill the hole back with the soil you dug from and water. Maintain soil moisture, especially in the tree's early years, by providing deep, regular watering. Apply a 2-4 inch mulch away from the trunk at the base to retain moisture and suppress weeds. Prune trees during the first few seasons to establish strength and resilience, remove damaged branches, and continue maintenance pruning as the tree matures. Regularly inspect for pests and diseases and apply integrated pest management practices. Protect young trees from mechanical damage and extreme temperatures with tree guards, and stake them if necessary for support, removing the stakes after one or two years.
