Colossal Chestnut TC Tree

Colossal Chestnut TC Tree

*These Colossal Chestnuts were produced through tissue culture propagation and are therefore on their own roots.

Colossal Chestnut TC Tree – This hybrid of Japanese and European Chestnut, is disease resistant and bears abundant crops of large, sweet nuts. In the fall you can harvest bountiful crops of sweet and nutritious nuts encased in unique, spiny, golden brown balls. Unique among nuts, Chestnuts are high in starch and are delicious after processing. If you do not eat your nuts shortly after harvest, it is best to refrigerate them in plastic bags to keep them from drying out. Chestnuts like well-drained soil, full to half day sun and can grow 25 ft. or more in height at maturity. They are hardy to minus 25 degrees F., USDA Zone 4 and usually begin bearing 2-4 years after planting. Plant two or more plants for cross-pollination.
