[Chestnut tree pollination requirement is variable, depending on the type of chestnut tree planted. Chinese Chestnut trees will produce Chestnuts from a single planted seedling tree, although some growers claim that the crop size of Chestnuts will increase if two trees are planted. Most growers of American Chestnut trees claims that two different trees should be planted to produce American Chestnuts. Hybrid Chestnut unions of American and Japanese Chestnuts require a pollinator of compatible pollen shedding viability, Hybrid Colossal chestnuts must be planted with a seedling Chestnut pollinator. Wildlife Chestnuts trees are self pollinating and will produce Chestnuts from a single tree.]
