Water Stress (Underwatering or Overwatering)

Tomato plants require consistent moisture to maintain turgor pressure in their leaves. Severe drought causes wilting to conserve water, while waterlogged soil leads to root hypoxia and eventual wilting due to impaired nutrient uptake.

Very Common

lightbulb

How to confirm: Check the soil moisture 2 inches below the surface; if bone dry, it is underwatering, and if muddy/saturated, it is overwatering.

1 Check the soil moisture level at the root zone using a moisture meter to determine if the plant is suffering from drought 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 completely before next watering.

3 Ensure the plant is in a container with excellent drainage, such as a Root & Vessel pot, to prevent future waterlogging and root rot.

Fusarium Wilt (Fusarium oxysporum f. sp. lycopersici)

This soil-borne fungus invades the tomato's vascular system, physically blocking the flow of water and nutrients. It typically causes unilateral wilting, where one side of a leaf or even one side of the plant droops first.

Very Common

How to confirm: Cut a small section of the main stem to check for internal reddish-brown discoloration in the vascular tissue.

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

2 Sterilize all gardening tools, such as your pruning shears, with alcohol to avoid transferring fungal spores to other plants.

3 Avoid planting tomatoes or other Solanaceous crops in this soil for at least two to three years, and consider amending the area with organic matter like worm castings to improve soil health.

Bacterial Wilt (Ralstonia solanacearum)

This pathogen colonizes the xylem of the tomato plant, producing large amounts of extracellular polysaccharides that plug the water-conducting vessels. This results in sudden, rapid wilting of the entire plant even when soil moisture is adequate.

Common

How to confirm: Cut a wilted stem and place it in a clear glass of water to see if milky white bacterial ooze emerges from the vascular bundles.

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

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

3 Rotate your planting location and avoid planting Solanaceous crops like tomatoes or peppers in this soil for at least two to three years.

warning

Temperature Extremes (Heat Stress)

High temperatures, especially above 90°F (32°C), cause rapid transpiration rates that exceed the plant's ability to pull water through its roots. This leads to temporary drooping during the hottest part of the day.

Common

How to confirm: Observe if the leaves recover and perk up during the cooler evening or early morning hours.

1 Provide immediate shade during peak afternoon heat to reduce transpiration rates and prevent further wilting.

2 Monitor soil moisture levels closely to ensure the plant remains hydrated without becoming waterlogged.
