Fruitless Mulberry Decline: Internal Decay After Pruning

Julie: old fruitless mulberry was lush when moved in. Trimmed winter before last. Leaves sparse since. 2-3 large dead branches. Ground cover at base. Asks if savable.

Expert Assessment

Steve: dead branches + thinning foliage = internal decay from fungal/bacterial microorganisms. Slow, progressive decline.

Management

• No "magic bullet"
• Fertilize and water correctly
• Eventually becomes hazard → removal

Key Insight

Pruning may have created entry points for decay organisms. Old mulberries are prone to internal decay. Ground cover at base may mask basal issues but isn't primary cause. Hazard monitoring is the long-term reality.
