swamp magnolia

Swamp Magnolia should be watered deeply about once per week, during the growing season. Allow the soil to dry out slightly between waterings. During the winter months, water about every 2 to 3 weeks, allowing the soil to dry out more than during the growing season. Extended periods of dry soil can cause leaf scorch, so make sure to check the soil often during periods of drought. Increase frequency of watering during periods of extreme heat.

Swamp magnolia (Magnolia virginiana var. australis) does best in part shade or full shade, with direct sunlight for only 2 or 3 hours per day. For optimal growth and flowering, it should get 4 to 6 hours of bright indirect sunlight each day, such as being in an area that gets morning sun followed by afternoon shade. Further south, where temperatures are usually higher, the plant may need additional protection from the afternoon sun.

Swamp magnolia (Magnolia virginiana var. australis) should be pruned in the spring and late summer to maintain a healthy and aesthetically pleasing shape. Late winter pruning can also help to control size. To promote flowering, thin out the woody stems and branches and prune shorter dead limbs. To prevent overgrowth, lightly prune to shape and remove branches that are crossing or dead. Pruning should be done shortly after flowering has stopped for the year, and should focus on removing dead wood and thinning out some of the larger branches. This should be repeated every 1-2 years, depending on the individual plant's health and growth rate.
