What kind of fertilizer do magnolia trees need?

Magnolia trees benefit from a balanced, slow-release fertilizer with an N-P-K ratio of about 10-10-10 or 12-4-8, applied in early spring as new growth begins. It's important to choose a fertilizer that is low in phosphorus, especially if you live in areas with phosphorus-sensitive ecosystems. Organic options, like compost or well-rotted manure, can also provide essential nutrients while improving soil health. Always follow the manufacturer's instructions for application rates to avoid over-fertilization.
