Care Guide

Watering

Water deeply and regularly to keep the root zone moist, especially during dry spells

Fertilization

Apply a balanced, slow-release fertilizer just before new growth begins. Fertilize primarily during the active early growing season.

Coffee Grounds and Banana Peels:Mix used coffee grounds into the topsoil around the drip line to provide gentle nitrogen and maintain slight soil acidity. Bury chopped banana peels shallowly to boost potassium for root and flower health. Avoid piling directly against the trunk.
Pruning
  • Prune immediately after flowering finishes in late spring;
  • Avoid late summer or winter pruning, as this removes the fuzzy buds set for next year's flowers;
  • Remove dead, diseased, or crossing branches to maintain an open, attractive framework;
  • Limit severe pruning, as magnolias are slow to heal from large cuts.
