How should potted magnolias be cared for in winter to do well?

Cultivation and management of white magnolia. White magnolia likes a sunny and humid environment and is not suitable for long-term growth in alkaline soil. The planting site should be a wind-sheltered, sunny, well-drained and fertile spot. Before flowering, there should be sufficient water and fertilizer to promote large, fragrant flowers. Magnolia has few branches, and apart from dead branches, diseased and pest-damaged branches, and branches that spoil the tree shape, it generally does not need pruning. After the flowers fade, if the seeds are not to be kept, the fruit should be cut off to avoid consuming nutrients. White magnolia has strong cold resistance and can overwinter outdoors in North China and the southern part of Northeast China.
