Pruning Won't Fix Sparse Magnolia: Fertilization Strategy

Two deciduous magnolias in San Diego: one healthy, one sparse leaves/occasional flower. Will pruning help?

Pruning ≠ Health Improvement

Pruning doesn't restore vigor. Fertilize instead:

Years 1–3: 1 lb (2 cups) 8-8-8 or 10-10-10 per 100 sq ft (area = 3× canopy spread) in March, May, July, September
Year 4+: Reduce to 1–2×/year
