Things You'll Need:
- Marigold plants
- Clear plastic sheeting
- Elbon rye plants
-
Step 1
Plant nematode-resistant crops like corn, onions, garlic and nematode-resistant tomatoes.
-
Step 2
Remove any plants that are suffering from nematode infestation to prevent the spread of these damaging worms.
-
Step 3
Once infested plants are removed, plant marigolds. Marigolds exude a chemical that is toxic to nematodes and can help rid the soil and surrounding plants of any remaining worms. Leave the marigolds in place for at least three months.
-
Step 4
If your entire garden is infested, remove all of the plants and till the soil. Allow the soil to dry completely and leave your garden dormant for a full summer.
-
Step 5
Cover the soil with clear plastic once the plants are removed and the soil has dried. Leave the plastic in place for six to eight weeks.
-
Step 6
In the fall, plant Elbon rye grass. Rye grass is nematode resistant, and can drive the worms away.
