No. 6' apricot rootstocks have performed well. For sandy soils where nem-
atodes are a problem, apricot or nematode-resistant peach rootstocks are
preferred. Peach rootstocks are not well suited to cold climates. On heavier
soils, myrobalan plum rootstocks can be used, but they produce weak unions,
gradual tree decline, and slow production.
Pollination.
Most apricot varieties are self-fruitful and can be grown com-
mercially in solid blocks, but some experts recommend planting two varieties
close together to ensure good fruit set. The varieties 'Goldrich', 'Perfection',
and 'Riland' require cross-pollination.
Unlike apples, relatively few apricot varieties are available in North
America. 'Blenheim' (also known as 'Royal') is the dominant commercial vari-
ety grown in western North America. Despite the limited number of variet-
ies, apricots are grown successfully from the deep southern United States
into the Canadian Prairie Provinces and southern Alaska. For southern loc-
ations with limited chilling temperatures, consider 'Zard', 'Katy', 'Goldkist',
'Newcastle', and 'Golden Amber'.
