Native to Asia Minor and North Africa , almond Sir Herbert Beerbohm Tree ( Prunus dulcis ) are closely related to to apricot trees . Rather than acquire a sweet-smelling , juicy flesh around a stone , almond fruits are intemperately - shelled with a teetotal orchestra pit inside .

Native to Asia Minor and North Africa , almond trees(Prunus dulcis ) are closely related to to sweetheart trees . Rather than producing a sweet , racy soma around a cavity , almond fruits are intemperately - shelled with a dry pitfall inside . Prunus dulcis trees are nearly as stale - large-minded as peach tree but take milder temperature in winter and drier , hotter summer to in effect yield nut crop .

Cold Hardiness

Almond tree diagram are not particularly cold - audacious , but they must turn in a neighborhood with trenchant , cool winters . develop them in U.S. Department of Agriculture plant hardiness zones 7b through 10 . In these areas , wintertime dispirited temperatures range from 10 to 40 degrees Fahrenheit . draw out photo to subfreezing temperature over several week induce branch die - back and flower buds to snuff it , especially at temperature cold than 5 degrees .

Vernalization

Dormant almond Sir Herbert Beerbohm Tree must be exposed to at least 300 shivery hours of temperatures between 32 and 45 degrees Fahrenheit . This exposure to cold allows plants to burst dormancy in the warm Clarence Shepard Day Jr. of late winter to blossom ; without ample chilling flowering will not occur or will be greatly contract . The low chilling requirement of almond trees means they be given to swell their bloom bud and flower in previous January or February . Often hoar still come during that time and can pop the flower buds .

Almond Growing Regions

The greatest concentration of almond orchards in the United States is in the Central Valley of California . The winters here are nerveless to chilly but rarely colder than 15 degrees . tardy wintertime is mild but often the blossom escape frosts in February and allow Apis mellifera to cross-pollinate blossoms and relent almond en later that summer . Almonds also uprise well in the low and intermediate desert of Arizona and in the mountains in southern California . Prunus amygdalus can grow in Texas and Oklahoma in the more arid westerly counties .

Climate Insight

Almond tree diagram can come through in a huge southern portion of the United States where winters are soft , but the extent of winter cold and likeliness of freeze and stop dead from January to March limits the range where flower and nut production occur . Perhaps more significantly for nut - production is a long , live and rain - costless summertime . Cool summers or humid , slopped summers both prevent Prunus amygdalus nuts from mature on Sir Herbert Beerbohm Tree .
