The Carpathian walnut is a large, fast-growing deciduous tree that thrives in full sun with deep, well-drained soil and regular watering until established. It is cold-hardy and relatively adaptable but needs plenty of space, as its roots produce juglone, a compound toxic to many nearby plants. Prune in late summer to avoid excessive sap bleeding and fertilize annually in early spring for best nut production.
