Reviving a Struggling Weeping Mulberry After Storm Damage

Post-Hurricane Care for Weeping Mulberry

A weeping mulberry (Morus alba 'Pendula') transplanted after Hurricane Katrina (2005) shows yellowing leaves and poor growth three years later. The tree needs targeted care to recover.

Soil pH and Fertilization

Mulberries prefer slightly acidic soil (pH 5.5–6.5). The recommended regimen:

• Product: Holly-Tone (acid-forming fertilizer, 4-3-4 with micronutrients)
• Rate: 1 cup per foot of branch spread; double for plants over 3 feet wide
• Application: Spread on soil surface, do NOT cultivate in (shallow roots)
• Timing: Early spring; repeat at half strength in late fall
• Mulching: Apply fertilizer before mulching, or double rate on top of existing mulch

Why This Works

• Acidifies root zone for better nutrient uptake
• Slow-release nitrogen prevents burn
• Fall feeding supports root development and spring reserves
• Micronutrients correct common deficiencies in alkaline soils

Additional Recovery Steps

1. Ensure consistent moisture – mulberry has shallow, wide-spreading roots
2. Check for girdling roots from container cultivation or transplanting
3. Prune only dead wood; avoid shaping cuts on stressed tree
4. Monitor for verticillium wilt (common in mulberries) – sudden branch dieback

Expected Timeline

Visible improvement in leaf color and shoot growth within 4–6 weeks of spring feeding. Full canopy recovery may take 1–2 seasons. If no response by midsummer, consult an arborist for root excavation and soil testing.
