The seed can remain viable in the soil for up to 39 years and can emerge from a depth of two inches. The seeds readily germinate when soil temperatures are between 68 and 100 F. Consequently, nightshade germinates from spring through summer. Those nightshade plants which emerge even in midsummer are capable of producing seed but the amount of seed produced declines as the plants germinate later in the season. Research from Minnesota showed that eastern black nightshade produced less than 85 berries per plant when planted in May, 0 to 3 berries when planted in June, and no berries when planted in July. However, if the canopy is defoliated in July from hail or insect feeding, nightshade planted in May produced up to 1,600 berries per plant.
