The Q&A Archives: Peat Pot Mold

Question: I am using a seed starting kit that includes a plastic dome and peat pots. I notice a white cotton-like growth on the edges of the pots and soil. Is this a fungus? Is it harmful? How should I treat it? Should I keep the lid off now that the seeds have germinated?

Answer: Quick! Take off the cover! Remove the lid as soon as the seeds germinate and place them in the brightest location you have. Seedlings need air circulation or they will often be attacked by fungus. Contributing factors to fungal attack are contaminated equipment or soil mix, lack of air circulation, and too much moisture. It is possible that you are keeping or have been keeping the soil too wet; try backing off a bit on the water and increasing the air circulation (removing the cover may be sufficient). Keep a close eye however since you don't want the seedlings to dry out completely, either.
