Best grown in deep, loamy, moderately fertile, slightly acidic, medium moisture, well-drained soils in full sun. Tolerates average garden soils, but unamended heavy clay soils which waterlog easily and drain poorly should be avoided. Generally, the more dwarfing the rootstock, the greater the need for soil fertility. Needs full sun for maximum flower and fruit production. More than one variety must be planted in order to facilitate best pollination and subsequent fruit production.
Stark Bro's Nursery of Louisiana, Missouri recommends Malus 'Enterprise' and Malus 'September Wonder Fugi' as good cross pollinators for Malus 'Sweet Sixteen.'
