Checking Tomato Root Systems for Problems

Examining tomato roots without harming the plant is challenging but possible. The primary concern is often nematodes, microscopic worms that attack roots.

How to Inspect Roots

1. Gently remove soil from around the base of a suspect plant.
2. Look for white, sticky material attached to roots—this indicates nematode infestation.
3. Healthy roots are white and firm; diseased roots are brown, mushy, or knotted.

If Nematodes Are Found

Nematodes are difficult to treat. Consult a local garden center for liquid injection treatments. Solarizing soil (covering with clear plastic for 6 weeks in hot summer) can reduce populations. Rotate crops and plant resistant varieties (marked 'N' on labels) in future seasons.

Prevention Tips

• Add organic matter to encourage beneficial soil organisms.
• Avoid moving contaminated soil to clean areas.
• Clean tools with 10% bleach solution between beds.

Early detection is key—check roots at first sign of unexplained wilting or stunting.
