Morphological Characteristics of the Chestnut Tree

Chestnut trees are large, long-lived deciduous trees, growing from 15 to 35 meters tall with a broad canopy and straight trunk. The bark is dark gray, developing deep vertical cracks as the tree ages.

The leaves are lance-shaped with deeply serrated edges, dark green and glossy on the upper side, lighter underneath with fine hairs when young.

Chestnut trees are monoecious, with both male and female flowers on the same tree. Male flowers grow in long, catkin-like clusters, while female flowers are small and grow at leaf axils.

The fruit is a nut enclosed in a thick, spiny husk that splits open into four parts when ripe, revealing 1 to 3 large, shiny brown nuts.

Growth Characteristics of the Chestnut Tree

Chestnut trees prefer full sunlight and thrive in temperate and subtropical climates, in deep, moist, well-drained, humus-rich soils with slightly acidic pH. They are highly cold-tolerant and are suited to elevations between 500 and 1500 meters.

They grow relatively quickly, starting to bear fruit after 5 – 10 years, reaching peak productivity from 20 – 30 years, and can live 100 – 300 years, with some trees exceeding 500 years.

Chestnut trees flower in late spring to early summer, with nuts ripening in autumn, typically from September to November depending on climate.
