Care of Magnolia Trees & Bushes

Magnolia trees require plenty of water and fertilizer until established.

Magnolia trees and bushes are among the most widespread southern trees, according to the Mississippi Forestry Commission. This type of tree comes in many shapes and sizes and, once established, the magnolia tree does not require a lot of care.

Planting Needs

Magnolia trees and bushes grow best in rich, well-drained, acidic soil that is in full sun or partial shade. They do best in United States Department of Agriculture hardiness zones 7 to 9, though cultivars extend the magnolia's reach up toward zone 5.

Watering

When the weather is hot, water magnolias every seven to 10 days until the plant is established. Once this occurs, magnolias are quite drought resistant due to their extensive root system.

Fertilization

Magnolias require an application of 16-4-8 fertilizer once in March and again in June for the first three years. After that, magnolias can get enough nutrients from decomposing mulch, according to the University of Florida IFAS Extension.

Pruning

Unless the lower branches of magnolias are inhibiting regular maintenance, pruning them is unnecessary. However, removing stray limbs allows the trees and bushes to exhibit a pyramid-like shape.
