Summary

Castanea sativa, commonly known as the Sweet Chestnut or Spanish Chestnut, is a long-lived deciduous tree native to the deciduous forests of the Balkan Peninsula and Northern Iran. It has been widely cultivated throughout the temperate world for its edible seeds, known as chestnuts, which have been a staple in cooking since ancient times. Castanea sativa typically attains a height of 20–35 m (66–115 ft) with a trunk diameter up to 2 m (7 ft). The bark is distinctive with a net-shaped (retiform) pattern and deep furrows. The tree’s straight trunk and low branching habit contribute to its majestic appearance. Sweet Chestnut trees can live for 500 to 600 years, and in cultivation, they may reach over 1000 years. The species is valued for its genetic diversity and various cultivars, which are used for producing flour, boiling, roasting, drying, sweets, or wood.

The Sweet Chestnut thrives on acidic, deeply weathered, limestone-free soils with a pH between 4.5 and 6, and it cannot withstand soil compaction or clay-rich, waterlogged conditions. It is a heat-loving species requiring a long growing season, with optimal average temperatures between 8 °C and 15 °C. The tree is sensitive to low autumn temperatures which can damage the fruit, but it can survive winter lows down to -15 °C. The tree prefers climates similar to those suitable for viticulture, with annual precipitation between 400 and 1600 mm. Stratification of seeds at 2-3 °C is necessary before planting, and young trees are transplanted after a year. Sweet Chestnut produces showy yellow, green, and white flowers in the summer. It is best cultivated in full sun with medium water requirements and adaptable to various drainage conditions. Castanea sativa can become invasive outside its native range, so it is important to check local guidelines before planting.CC BY-SA 4.0
