About Sweet chestnut
Castanea sativa, commonly known as the sweet chestnut or European chestnut, is a majestic, deciduous tree of large stature, famous for its edible fruits, the chestnuts. It features a dense, rounded canopy with large, serrated, bright green leaves. It is ideal for large gardens, parks, or as a shade tree on estates, where its splendor can fully develop.

Care tips
It requires full sun exposure for good fruiting and optimal development. Watering should be regular, especially in the first few years and during dry periods, ensuring the soil remains moist but not waterlogged. It prefers deep, fertile, well-drained, and slightly acidic soils. Avoid calcareous soils, as they can cause chlorosis and severely affect its growth.
