Q.White Fungus on Seedling Dirt

Anonymous added on April 12, 2011 | Answered

I have taken off the cover over my seedlings and have also put a fan on them for air circulation, but the white fluffy stuff is still on the dirt. Is there anything I can put on the dirt that will get rid of this without harming my seedlings?

I'm assuming that you have tried the suggestions from the following article: https://www.gardeningknowhow.com/garden-how-to/seeds/preventing-white-fluffy-fungus-on-seed-starting-soil.htm

Evidently, the soil is still too moist; otherwise, the fungus would not grow. Are you watering too often? If so, allow the plants to dry out some. Let it air out for about a week, monitoring it often with your finger for dampness. If this doesn't help, there could be a problem with your potting soil--too heavy--or the container itself--poor drainage (check drainage holes). If the soil remains damp, you may want to consider transplanting (if feasible) using a lighter potting soil. Also, move the seedlings to an area offering additional light. When you do water again, try watering from the bottom rather than the top.
