Water Stress (Underwatering or Overwatering)

Tomato plants require consistent soil moisture to maintain turgor pressure in their leaves. Both dehydration and waterlogged soil (which causes root hypoxia) prevent the plant from transporting water effectively, leading to wilting.

Very Common

lightbulb

How to confirm: Insert your finger 2 inches into the soil; if it is bone dry, the plant needs water, but if it is soggy, you are overwatering.

1 Check the soil moisture level at the root zone using a moisture meter to determine if the plant is suffering from dehydration or waterlogging.

2 If the soil is bone dry, water the plant thoroughly until water drains from the bottom; if the soil is saturated, allow it to dry out before the next watering.

Fusarium Wilt (Fusarium oxysporum f. sp. lycopersici)

This soil-borne fungus invades the vascular system of the tomato plant, physically blocking the xylem. This results in characteristic one-sided drooping and yellowing that starts on lower leaves.

Very Common

How to confirm: Cut a small section of the main stem near the base; look for brown, discolored vascular tissue inside 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.

2 Sterilize all gardening tools, such as pruning shears, with alcohol to avoid cross-contamination of the fungus.

Bacterial Wilt (Ralstonia solanacearum)

This pathogen enters through root wounds and colonizes the xylem, producing large amounts of extracellular polysaccharides that plug the plant's water transport.

Common

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

1 Immediately remove and destroy the infected plant and all surrounding debris to prevent the bacteria from spreading to healthy tomatoes via soil or water.

2 Sterilize all gardening tools, such as pruning shears, with a 10% bleach solution or alcohol to avoid cross-contamination during future maintenance.

3 For future plantings, improve soil drainage by incorporating perlite or coarse sand to prevent the waterlogged conditions that favor bacterial movement.

Extreme Temperature Stress

High daytime temperatures combined with high humidity can cause tomatoes to undergo temporary wilting during the hottest part of the day to reduce transpiration.

Common

How to confirm: Observe if the leaves recover and perk up once the temperature drops in the evening or early morning.

1 Provide temporary shade during peak afternoon heat to reduce transpiration and lower the plant's temperature.

2 Monitor soil moisture levels closely to ensure the plant isn't also suffering from dehydration during heat waves.
