Wilt: when your plant collapses overnight
Moist soil but a plant that’s suddenly drooped and won’t recover? That’s wilt — a fungal or bacterial disease. Here’s how to stop it spreading and prevent the next one.
Wilt is a fungal or bacterial disease that blocks a plant’s plumbing, so it suddenly droops and collapses even though the soil is moist — the classic, heartbreaking “fine yesterday, dead today”. It lives in the soil and commonly hits tomato, brinjal, beans, gourds and banana.
There’s no spray that cures a wilted plant, so the whole game is prevention and containment: keep the soil healthy and well-drained, build in the good fungus Trichoderma viride, rotate your crops, and the moment a plant goes down, get it out of the ground before it takes the bed with it.
Remove affected plants fast
Wilt spreads through the soil. Pull and destroy collapsed plants (bin them, don’t compost) before neighbours catch it.
Don’t over-water
Soggy, airless soil is where wilt fungi thrive. Water only when needed and make sure pots and beds drain freely.
Use Trichoderma viride
This beneficial fungus, worked into the soil or compost, suppresses the fungi that cause wilt — a genuinely effective organic preventive.
Spray a baking-soda solution
An alkaline baking-soda-and-water spray makes conditions less friendly for the fungus on the plant surface.
Rotate and choose resistant varieties
Don’t grow the same family in the same spot season after season, and pick wilt-resistant varieties where you can. Good air circulation helps too.
Frequently asked questions
Why did my plant suddenly wilt and die?
If the soil was moist, suspect a fungal or bacterial wilt — a soil-borne disease that blocks the plant’s water transport. It can’t be cured once advanced; remove the plant to stop it spreading.
How do I prevent wilt organically?
Don’t over-water, ensure free drainage and good airflow, work Trichoderma viride into the soil, rotate crops, and choose resistant varieties.
Which plants are prone to wilt?
Tomato, brinjal, beans, gourds and banana are common victims.
What is Trichoderma viride?
A beneficial fungus that suppresses the soil fungi responsible for wilt — an effective organic preventive added to soil or compost.
