Water: Magnolias 'Susan' requires watering primarily when young or during drought. Immediately water after planting, then again when water seeps through, and repeat 4-5 times. After establishment, watering can be reduced. In hot seasons, water morning and evening; unnecessary in other seasons.

Fertilize: Apply organic fertilizer at the base of magnolias 'Susan' in spring for nitrogen to support leaf growth. Later, especially after heavy rains, use a potassium-rich fertilizer like potash in the fall to restore nutrients before winter dormancy.

Pruning: Magnolias 'Susan' is a deciduous shrub known for its deep purple-red blooms. Prune in early spring to remove dead branches and promote healthy growth. Light pruning enhances air circulation and improves blooming. Regular maintenance ensures a compact form. Use clean, sharp tools to prevent disease.

Propagation: Magnolias 'Susan' can be grown from seed or established trees. For seed propagation, soak seeds, remove coatings, and chill for three months before planting. Seedlings need moisture and indirect sunlight. Alternatively, use layering or softwood cuttings in spring for deciduous trees and semi-ripe cuttings in fall for evergreens.
