This tree was introduced to the Facebook versions of Pet Society on November 9, 2009.
After planting, it will take 72 hours for the chestnut tree to reach maturity. Afterward, the tree will begin producing fruit, one chestnut at a time, randomly. A pet can have up to three total chestnuts on the tree at once.
Homegrown Chestnuts from this tree can be used to fish at the Pet Society Pond. These fruits will catch common fish and decorative / junk items. These fruits are one of two items that can catch the Chestnutfish.
