Colossal Chestnut Tree (Castanea sativa x crenata 'Colossal') Pollination Information:

The Colossal Chestnut Tree is partially self-fertile, but it produces larger and more abundant nuts when cross-pollinated with another variety of chestnut tree. The tree flowers in late spring or early summer, producing long, creamy white male catkins and shorter, plumper female flowers on the same tree. The female flowers are receptive to pollen for about two weeks.

Pollination occurs through wind and insect activity. The transfer of pollen from the male catkins to the female flowers results in the formation of chestnuts, which mature in the fall.

To ensure optimal pollination and nut production, it is recommended to plant at least two different varieties of chestnut trees within 200 feet of each other.
