Why Your Mature Magnolia Drops Excessive Leaves in Spring

Natural Seasonal Shedding

Magnolias (evergreen types) shed interior leaves each spring as new growth shades them out. This is normal—like pines dropping old needles. Environmental fluctuations cause heavier drop some years.

Irrigation Check

Sprinkler systems often wet only the top few inches. Deep water weekly (1 inch via pan test) to reach 18-24 inches. This reduces stress-induced shedding.

Shade Consideration

The nearby oak compounds interior shading. No pruning needed unless branches rub. Accept seasonal leaf drop as healthy renewal.
