About Kieffer
Kieffer is the tough, adaptable pear for difficult climates — a European-Asian hybrid with exceptional disease resistance and low chill requirements. Best for canning and preserves rather than fresh eating.
Kieffer requires 350 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
Gritty texture and mild flavor make it poor for fresh eating; primarily a cooking pear.
❌ Common Misconception
Will Kieffer produce more fruit in colder climates?
Not necessarily. Kieffer only needs 350 chill hours. Planting in very cold zones (3 or colder) risks winter damage without improving fruit production. The ideal zones are 4-9 where the tree gets enough chill without excessive cold stress.
If you plant it, write it down.
