Apricots have a chilling requirement of 300 to 900 chilling units. A dry climate is good for fruit maturation. The tree is slightly more cold-hardy than the peach, tolerating winter temperatures as cold as −30 °C (−22 °F) or lower if healthy. Apricot cultivars are usually grafted onto plum or peach rootstocks. The cultivar scion provides the fruit characteristics, such as flavour and size, but the rootstock provides the growth characteristics of the plant.
