Pomegranates through the year
Against the frost risk in Jersey City
Why these dates
Survives to around -12C once established. The obstacle in a cool climate is not winter but summer: without sustained heat the fruit never develops.
Pomegranates are planted once and then left in place, so there is no sowing offset to resolve. Nor is there a dormant season to plant into: this crop keeps its leaves and keeps growing through the winter, which is exactly why cold damages it. The window on this page therefore waits until the last frost in Jersey City has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.
Jersey City sits in zone 7b, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. The dates below still describe the right time of year; the open question is survival rather than timing.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 3, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
