If you notice that your seedlings are starting to shrink and wither, it’s crucial to identify the cause and take appropriate action.
Identify the Cause
Curled leaves can indicate either excessive moisture or a lack of it. For seedlings that are 14 days old, ensure you water them with warm water to a depth of 15 mm. After watering, remember to loosen the soil to prevent a hard crust from forming.
Light Issues
If the lower leaves are curling, this suggests that your seedlings are receiving too much light. In this case, consider rearranging the seedlings or turning off any additional lighting.
Fertilization Problems
Over-fertilization could also be an issue. Feed your seedlings for the first time 14 days after transplanting or when the first true leaves appear. If you’ve used self-prepared soil, fertilize every 14 days. For peaty soil, feeding should occur every 7 days.
Temperature Control
Drying and yellowing leaves may result from improper temperature conditions. The optimal daytime temperature for growing seedlings is between 20 to 22 degrees Celsius, while nighttime temperatures should range from 16 to 18 degrees Celsius.
By addressing these factors, you can help ensure your seedlings thrive and avoid loss!
