Underwatering / Drought Stress

Tomatoes have high transpiration rates and require consistent moisture. When soil moisture is depleted, the plant loses turgor pressure, causing leaves to wilt to conserve water.

Very Common

How to confirm: Insert your finger 2 inches into the soil; if it feels bone dry, the plant needs immediate irrigation.

Fusarium Wilt (Fungal Pathogen)

Fusarium oxysporum is a soil-borne fungus that invades the vascular system of the tomato plant. This blockage prevents water transport, leading to characteristic one-sided wilting or yellowing.

Very Common

How to confirm: Check if the wilting starts on only one side of a leaf or stem and look for brown discoloration in the cross-section of the stem.

1 Immediately remove and destroy the infected plant and any surrounding debris to prevent the soil-borne fungus from spreading to healthy plants.

Overwatering and Root Rot

Excessive water displaces oxygen in the soil, causing roots to suffocate and decay. Damaged roots cannot absorb water, which paradoxically results in wilting leaves despite wet soil.

Common

How to confirm: Check if the soil remains saturated for long periods and inspect the roots for a dark, slimy texture and foul odor.

1 Immediately stop watering and allow the soil to dry out completely to restore oxygen to the root zone.

2 Repot the tomato plant in fresh, well-draining potting soil and consider adding perlite to improve aeration and prevent future rot.

3 Prune away any mushy, blackened, or dead roots you encounter during repotting to prevent the spread of decay.

Bacterial Wilt (Ralstonia solanacearum)

This pathogen enters through root wounds and colonizes the xylem. It causes rapid wilting of the entire plant, often occurring suddenly even when soil moisture is adequate.

Common

lightbulb

How to confirm: Cut a wilted stem and place it in a clear glass of water; if a milky white bacterial ooze emerges, it is bacterial wilt.
