The Bartlett pear tree is unique among the pears we have in stock. It is an ideal pear for more northern regions. It does best in USDA Zones 5-7. Bartlett is partially self-fruitful but does best with another pear tree nearby (such as Ayers, Kieffer, Moonglow, wild pear), and it is a vigorous tree with tasty, crisp fruit. Not a drought tolerant tree. 800 chill hours.
