University of New Hampshire researchers have shown it's possible to grow strawberries in the state from early summer through late fall.
The New Hampshire Agriculture Experiment Station researchers said Monday that the key is growing specific varieties of fruit in specific conditions.
Traditionally, New Hampshire's season for strawberries is only four to six weeks, from mid-June until early July. The research shows that planting different types of strawberries and growing them under low tunnels increase the length of the season and strawberry yield.
The latest news from around the state
Most growers plant June-bearing strawberries, which are strongly affected by day-length and only initiate flower buds under short-day conditions, resulting in a brief period of fruit production.
Researchers evaluated eight varieties of day-neutral strawberries, which produced fruit from early July into November.
