Pests in Gardens and Landscapes

Magnolia—Magnolia spp.
Family Magnoliaceae (Magnolia family)

Plant identification

Magnolia spp. are deciduous and evergreen trees and shrubs. Their size varies by species. They are known for lovely spring blossoms.

Optimum conditions for growth

The climatic zone for Magnolias varies by species. Trees do well in areas of full sun but in hot summer areas may prefer partial shade. They require deep and thorough watering. Most magnolias are not tolerant of drought conditions and do best in rich, well-drained soils. Prune as little as possible and if required, prune just after flowering. Avoid gardening under plants because of sensitive surface roots. Do not transplant after plants are established.
