Almond trees thrive in a climate that has mild, wet winters and hot, dry summers. Almond trees grow best on deep loam soil consisting of clay, sand, humus or other organic material. This soil allows for optimal permeability, water retention and root zone aeration. When preparing to plant a new Almond orchard, growers cultivate the soil to loosen clods and grade the orchard. It is common practice to use a chisel attachment to dig deep down and break up any hardpan below the surface of the soil to help newly planted trees establish a deep root system.
Temperature is a major factor affecting the germination rate. The temperature range between 2 °C and 7°C is generally the most efficient. Seeds from Almond and other Rosaceae species need a cold treatment under humid conditions to overcome the dormancy and promote their germination.
