When to plant pomegranates in Puebla

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 Puebla has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.

Hardiness is not the obstacle here. Puebla is zone 10b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.

One caution specific to warm climates: this crop needs roughly 150 hours below 7.2°C (45°F) over winter before it will flower properly, and the coldest month in Puebla averages 14.6°C (58.3°F). Low-chill varieties exist for exactly this situation and are worth seeking out by name.

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.
