About Chinese chestnut
Castanea mollissima, commonly known as Chinese Chestnut, is a medium to large deciduous tree, prized for its edible nuts and disease resistance. It features dense, dark green foliage with lanceolate, toothed leaves that turn yellow or golden in autumn, offering seasonal appeal in large gardens, parks, or as a fruit tree in orchards.

Care tips
It requires full sun for optimal fruit production and healthy growth. Watering should be regular during dry periods, especially in its early years, avoiding waterlogging as it prefers well-drained, slightly acidic soils. A common mistake is planting it in heavy or alkaline soils, which can lead to chlorosis and poor development.
