June-Bearing Strawberries
The strawberry most commonly grown in Pennsylvania is the June-bearing strawberry. June bearers are the type most often grown by commercial growers, and are the result of decades of breeding for productivity, size, and other attributes. These varieties are rated as early, midseason, or late according to when they bear (
Table 8.1). The early varieties may be more subject to frost injury because they bloom earlier, and the opened blossom is the stage of fruit development most susceptible to frost injury. Strawberry varieties all ripen about 30 days after bloom.
