Most varieties of almond trees grow best in climate zones five through nine. Almond trees grow well in warmer climates, and each variety grows best in a particular zone.
Most of the almonds grown in the United States come from California because of its hot, dry climate in the summer and the mild winter climate. A fully grown almond tree reaches about 12 to 20 feet in height, and most almond trees begin to produce fruit when they reach 2 to 4 years of age. The nuts develop inside of this fruit, which resembles a peach. Nuts can be consumed raw after drying for a few days or roasted. Many people enjoy pressing almonds with water to create almond milk.
