Water: Magnolias 'Iolanthe' requires initial watering after planting and again after 3 and 5 days. Established trees can thrive with less frequent watering, especially during droughts. Monitor moisture levels, using minimal water during hot seasons while avoiding excess in other times.

Fertilize: Apply organic fertilizer to the base of magnolias 'Iolanthe' in spring for nitrogen to support leaf development. In fall, use a potassium-rich fertilizer like potash to replenish nutrients, especially after heavy rain, before the plant enters dormancy for winter.

Pruning: Magnolias 'Iolanthe' thrives with early spring pruning, focusing on thinning overcrowded branches and removing dead wood. Cut above a bud facing the desired growth direction to promote health and flowering. Timely pruning maximizes recovery and boosts blooms for the next season.

Propagation: While magnolias 'Iolanthe' is usually planted as a young tree, it can also be grown from seeds, though they are hard to find. Collect seeds from fresh pods in early fall. Germinate seeds by soaking, chilling, and planting. Magnolias 'Iolanthe' may take 10-15 years to flower. Propagation is also possible via layering and cuttings.
