Preparing Seeds To Minimize the Risk of Seedlings Damping Off

Damping off is a disease of newly germinated seedlings prior to their development of woody tissues. High-quality seeds invigorated with moist, cold stratification will germinate rapidly under suboptimal conditions, and therefore reduce the time a seedling is vulnerable to damping off. An optimal invigoration of the seeds requires stratification times that will result in sprouted seeds, unless moisture levels are properly balanced to be high enough for stratification to be effective, yet low enough to prevent premature radicle emergence. A four- step process for adjusting seed moisture and conducting cold moist stratification can reduce damping off risks. This paper was presented at the joint annual meeting of the Western Forest and Conservation Nursery Association and the Intermountain Container Seedling Growers’ Association (Troutdale, OR, September 14–15, 2016).
