The cotyledons (the first leaves to appear) turn soft, mushy, and may appear grayish brown.
Young leaves wilt and turn brown.
Roots are stunted or absent, and fluffy white cobweb-like growth may appear on the infected plant.

With some easy steps, you might avoid moldy seedlings and raise healthy plants.
What Is “Damping Off” Disease?
Damping-off is because of several soil-borne fungi, includingPythiumspp.,Rhizoctonia solaniandFusariumspp.

Once several sets of true leaves appear, the seedlings outgrow their susceptibility to damping-off disease.
Rinse with clean water after scrubbing.
Check the mix in the containers daily to determine watering needs.

If the soil feels moist, no need to water.
ensure to use trays or containers with drainage holes in the bottom to avoid soggy soil.
Install a fan near your seedlings, and run it for at least a few hours a day.

Improve the Light
Take a careful look athow much light the seedlings are getting.
That also helps the water to dissipate and not sit stagnantly.
Avoid direct sunlight, because covered trays will get too hot and may damage the seedlings.

Manage the Temperature
Few seedlings will flourish in chilly or hot surroundings.
The best photosynthesis triggers when the temperature stays between 77 and 82 degrees Fahrenheit.
Thin or Repot Seedlings
Most gardeners plant several seeds in the same seedling pot or tray.

If you’re lucky, all of the seeds will sprout.
Once they start to really take root, though, they will start to crowd one another.
Crowding reduces adequate airflow and can lead to fungus.
The Spruce / Jayme Burrows
Don’t wait too long to repot your seedlings.
Wait for two sets of actual leaves before transplanting.
Water Properly
Most seedling mold is a result ofwatering too much.
The Spruce / Jayme Burrows
Don’t water unless the seedlings need it.
Check the soil’s moisture with your finger, and only water if the soil is dry.
However, be careful not to allow the seedlings to completely dry out.
