Waxleaf Privet Decline: Nematodes or Atomic Grow

Old Privets Wilting and Dying in Water-Restricted Area

5–6 plants, 20+ years, partial shade, among healthy plants. Water twice weekly per mandates. No visible insects.

Answer

Nematodes damage ligustrum roots: galls, stubby roots, lesions. Cause wilting, nutrient deficiency, leaf drop, death. Resistant rootstock: Ligustrum quihoui. Control limited on established plants. Atomic Grow claimed to repel nematodes or restore health via organic drench.
