About McIntosh
McIntosh is the quintessential New England apple — tender, juicy, and intensely aromatic with a wine-like tang. It's the parent of many modern varieties including Cortland and Empire.
McIntosh requires 900 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
Flesh softens rapidly after harvest; highly susceptible to apple scab in humid regions.
Common Misconception
Can I grow McIntosh in Zone 8 or warmer?
No. While McIntosh is listed for zones 3-7, it requires 900 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.
