I've started flower and vegetable seedlings in peat pots. A whitish mold has recently appeared on the surface of the peat pots. Will the mold harm the seedlings?
The whitish or brown molds that grow on the surface of peat pots and other organic materials are unsightly, but will not harm healthy seedlings. However, the presence of molds may indicate excessive moisture levels. Overwatering may lead to damping-off and other serious problems. To avoid problems associated with overwatering, allow the potting soil to dry somewhat between waterings. Proper watering will also minimize the growth of molds on the surface of the peat pots.
