About Hosui
Hosui means 'much water' in Japanese — and this golden-russeted Asian pear delivers explosive juiciness with rich, sweet flavor. It's considered the best-tasting Asian pear by many growers.
Hosui requires 450 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
Russet skin is prone to cracking in wet weather; birds and wasps love the high sugar content.
Common Misconception
Will Hosui produce more fruit in colder climates?
Not necessarily. Hosui only needs 450 chill hours. Planting in very cold zones (4 or colder) risks winter damage without improving fruit production. The ideal zones are 5-10 where the tree gets enough chill without excessive cold stress.
