Amur cork tree

The Amur cork tree should be watered deeply every 10-14 days during growing season. Water until the soil is saturated and allow the top inch of soil to dry before watering again. Pay attention to the environment, trees in drier areas may need to be watered more often. During the winter months, reduce watering to every 20-30 days. In very cold climates, you may need to stop watering altogether to allow the tree to experience a brief winter dormancy.

Amur cork tree (Phellodendron amurense) requires direct sunlight for a minimum of 4 to 6 hours per day. For optimal growth and flowering, this species thrives best in full sun, however it can tolerate partial shade. It grows best in warm climates with temperatures between 55-70°F. During the late spring and summer months, the Amur cork tree should receive the majority of its light between 10am and 5pm. During the winter, the tree should get some light between 10am and 4pm.

Pruning an Amur cork tree is essential to maintaining its overall health and structure. Pruning should be done in late winter, when the tree is still dormant. Begin by removing any dead, diseased, or broken branches. As the tree matures, thin out any crossing or rubbing branches, and selectively prune lower branches to open the tree canopy to light and air circulation. Make sure to avoid pruning more than 1-third of the tree in any given season. Some light pruning may also be done at other times of the year.
