Ligustrum Sudden Defoliation: Leaf Spot or Root Rot

One of five ligustrums stripped of leaves in 2 days, appearing dead; others unaffected. Proper water/fertilizer maintained.

Possible Causes

Leaf spot fungi cause premature drop (light-dark brown spots with yellow border). Root rot causes sudden wilt/death with few healthy roots. Both require fungicide + sanitation for leaf spot; root rot has no cure once infected.

Action

Check drainage. Use slow-release fertilizer. Atomic Grow (organic) restores health continuously vs. fungicide alone which only temporarily suppresses fungus.
