Stratification time varies depending on the species of tree. Fruit trees need from 60 to 150 days of cold stratification, depending on variety. Maple trees need 40 to 120 days, while oak and redbud varieties need only 30 to 60 days. Hickory, chestnut and buckeye seeds need 90 to 120 days of stratification.
