How To Sample Root-Knot Nematodes Before Planting A Fig?
Q: How do I sample for root-knot nematodes before planting a fig?
A: Nematodes are tiny worms in the soil. Some species, like root knot nematode, harm plants by parasitizing roots. It is difficult to sample for nematodes before you plant. They will not be present in great numbers until a susceptible plant has grown in the spot for a few years. Even then, the number of nematodes around the plant varies greatly from spot to spot, depending on soil moisture and temperature. Unless you have definitely seen nematode damage where you plan to put your fig, I doubt they are present. Call your local University of Georgia extension office (800-ASKUGA1) for instructions on how to submit a soil sample if you decide to proceed.
