Fruitless Mulberry Leaf Spot: Rake Leaves, Spring Copper Spray

Diagnosis

Brown splotches + massive premature leaf drop = leaf spot fungi. Fungi overwinter on fallen leaves.

Immediate

Rake and remove all fallen leaves (off-site). Reduces spore load for next spring.

Spring Protocol

1. At leaf emergence: copper fungicide (Bordeaux mix).
2. Repeat every 2 weeks until leaves mature (3–4 sprays).

Tall Tree Reality

2-story height = spraying impractical. Commercial sprayers expensive.

• Accept: Leaf spots won't kill tree. Premature drop = growth loss only.
• Rake annually: Best solo management.
• Vigor: Water/fertilize to tolerate defoliation.

Don't risk ladder/sprayer on tall tree. Sanitation + vigor = sustainable approach.
