Yellowing Tomato Tops After Heavy Rain: Waterlogged Soil or Fungal Disease?

Introduction

Sudden yellowing of new tomato growth after heavy rain suggests waterlogged soil or early fungal infection.

Check Soil Drainage at 12 Inches

Dig down—if soil is saturated, roots are drowning.

Monitor for Wilting and Browning

If yellow leaves wilt and brown, fungal wilt (fusarium/verticillium) is likely.

Avoid Topping Plants

Cutting tops won't help; infected plants must be removed.

Conclusion

Check drainage first. If soil is wet, wait it out. If wilting follows, remove plants.
