Jane Magnolia Leaf Spot: Fungicide Now, Prevent Next Spring

Lower MI. Jane Magnolia (planted 1 yr ago) bloomed beautifully, now leaves yellow/brown with dark spots, dropping fast. 3 weeks ago. Help?

Fungal Leaf Spot

Wet spring = perfect for leaf spot fungi. Spots → yellow → drop.

Action

  1. Fungicide spray now (chlorothalonil, copper) to stop spread.
  2. Fall fertilize (balanced) for vigor.
  3. Spring preventive: Spray at budbreak, repeat 2× at 10-day intervals.
  4. Rake all fallen leaves (remove inoculum).

Magnolia will recover; preventive schedule stops recurrence.
