About Jersey
Jersey is the heirloom blueberry that's been feeding American families since the 1920s — vigorous, adaptable, and incredibly productive. The late-season berries are smaller but intensely flavored, perfect for baking and preserves.
Jersey requires 800 chill hours — the number of hours between 32°F and 45°F during winter dormancy. Without enough chill, the tree may fail to flower properly or produce poor fruit.
Common Challenges
Smaller berries than modern varieties; upright growth needs regular pruning; fruit can be soft in hot weather.
Common Misconception
Can I grow Jersey in Zone 8 or warmer?
No. While Jersey is listed for zones 4-7, it requires 800 chill hours to produce fruit. Warm zones like 8+ typically receive only 200-400 chill hours. The tree may survive but will not fruit reliably. Consider low-chill alternatives like Anna apple (200h) or Tropic Snow peach (200h) instead.
