My seedlings looked healthy until one day they started to wilt and die, soon the whole tray of seedlings were dead what happened?
The most likely villain here is a disease called “Damping-Off”. It causes seedlings to rot at the soil line, topple over and die, and it can affect the whole tray of seedlings within 24 hours. There is no cure for this disease. The best thing to do is remove all infected plants and throw in a trash receptacle. Do not reuse soil or compost the soil or seedlings to prevent the disease from spreading in the soil. Prevention Disinfect all tools used for seed starting and gardening with a bleach solution. (one part bleach to 4 parts water). Make certain there is good drainage and use a fan for air circulation around seedlings. Use only sterilized seed starting mix.
