The Granny Smith apple tree is a vigorous, hardy variety known for its tart, crisp apples. It grows to about 4 to 6 meters high and wide, making it suitable for medium to large gardens. The fruit has a bright green skin and a sharp, tangy flavor, perfect for eating fresh or using in cooking and baking. This tree is self-pollinating but benefits from nearby pollinators for increased fruit production. It thrives in full sun, well-drained soil, and requires moderate watering. The Granny Smith tree typically produces fruit in late autumn, and the apples can be stored for long periods after harvest.
