About Bluecrop
Bluecrop is the world's most widely planted blueberry — the reliable workhorse that produces heavy crops of firm, flavorful berries year after year. It's the benchmark variety for commercial growers and the standard against which all others are measured.
Bluecrop requires 700 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
Overbearing can lead to small berries without pruning; susceptible to mummy berry; needs acidic soil (pH 4.5-5.5).
❌ Common Misconception
Can I grow Bluecrop in Zone 8 or warmer?
No. While Bluecrop is listed for zones 4-7, it requires 700 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.
