Chestnut 'Six Mile' Seedling
Chestnut 'Six Mile' Seedling
Cultivar & Origin
Six Mile seed is collected from productive trees near Nelson in southern interior British Columbia. Our source records identify American–Japanese chestnut ancestry. The parent trees combine an upright, substantial canopy with useful-sized nuts. These traits, together with their performance in the established local planting, define the recorded selection background of this seed-grown batch.

Why We Grow It
Why We Grow It
Six Mile comes from our recorded American–Japanese chestnut source near Nelson. The parent trees combine an upright, substantial tree form with useful-sized nuts. We value that combination for larger agroforestry plantings: a canopy that can develop timber form and shelter while producing a starchy food crop beneath it.
How the Plant Grows
How the Plant Grows
Chestnut trees grow with a strong, upright trunk and a broad, spreading canopy, creating shade for understory plants. The more chinese the heritage the more spreading the tree. They can even have multiple trunks and look like a shrub for the first decade. They bloom in late spring with long catkins, which attract pollinators, followed by the development of spiny burrs that mature in autumn, each containing 1-3 nuts. In agroforestry systems, strategic planting on berms or using the pit-and-mound technique enhances drainage and tree health, ensuring consistent yields. Over time, the trees develop into majestic, long-lived providers of food, timber, and ecological benefits.

Additional Info
Additional Info
Chestnuts have been a key food source for countless cultures across the temperate world, cherished for their ability to produce starchy, nutritious nuts. These nuts are consumed raw, roasted, or processed into flour, offering a versatile ingredient for many dishes. The high carbohydrate content of chestnuts makes them an excellent feed for livestock in integrated systems, reducing the need for external feed sources and enhancing sustainability. Chestnut wood is highly valued for its durability, especially in mushroom cultivation, as it provides an ideal substrate for growing diverse fungi species. In agroforestry practices, dense planting followed by strategic thinning allows for optimized nut production and timber harvesting, minimizing waste and maximizing resource use.
Six Mile — seedling origin
Chestnut has been called the bread tree: a source of starchy nuts that can form part of a staple diet. Across European and Asian cultures, chestnuts have supplied flour, cooked meals and winter food. They also have potential in silvopasture, combining a canopy crop with managed grazing beneath established trees.Share

Plant Highlights
-
Water
Needs regular watering during establishment and the growing season for healthy nut development. Mature trees exhibit moderate drought tolerance
-
Pollination
Monoecious but requires at least two trees for cross-pollination. Plant trees 25 feet apart or closer for effective pollination.
-
Soil
Thrives in well-drained, loamy soils; prefers slightly acidic to neutral pH levels (4.5-7.0). We've seen trees in clay, silty and other mixed soil types. Very adaptable overall to soil type.
-
Years to Bear
Begins producing nuts at 5-10 years from planting, with increasing yields as the tree matures
-
Hardiness
Zones 4-9, tolerating temperatures as low as -34°C (-30°F)
-
Solar
Requires full sun for optimal nut production; tolerates light shade but with reduced yield.
