Q&A – How do I get root knot nematodes out of my garden?

Root knot nematodes can be difficult to control. UT Extension Agent Booker T. Leigh gives several control options. He says you can use a nematicide to kill them, dig out the top few inches of soil and replace it, or put down plastic in the heat of summer. The greenhouse formed under the plastic will cook them. University of Memphis Director of Landscape Joellen Dimond suggests leaving half the garden unplanted for a year. If the nematodes have nothing to eat, they will die. UT Extension Agent Chris Cooper suggests adding more organic matter to the garden. This will introduce beneficial nematodes that will control the bad nematodes. He also suggests planting nematode resistant plants.
