Nematode problems are most common in nursery plantings. Nematodes are tiny, worm-like parasites found only in the soil that feed on the roots. The root damage causes an overall stunting of affected plants, and plants may also show signs of drought stress or iron deficiency. Leaves can die back or drop prematurely, or entire plant tops may be yellowed. Nematode stunt symptoms often appear in a circular pattern. Soil samples must be taken to confirm nematode infestation.

  • Plant only clean stock to avoid introducing nematodes.
  • Plant nematode-tolerant species or varieties.
  • Provide proper culture. Healthy plants are more tolerant of damage.
