Fertilizing Magnolia Trees: The Right Approach

A homeowner with a large, non-blooming magnolia that drops leaves daily seeks feeding advice.

Acid-Loving Fertilizer Required

Magnolias thrive with acidic fertilizers—the same type used for rhododendrons and azaleas. Options include:

• Liquid: Quick green-up, fast response.
• Granular: Slower release, longer lasting.
• Organic (e.g., Holly-tone): Excellent balanced nutrition.

Application Rate and Timing

• Apply 1 pound per inch of trunk diameter, scattered around the tree.
• Water in thoroughly.
• Fertilize now and again in late summer.

Consistent acidity and nutrition support flowering and foliage health.
