WSU Tree Fruit

Pollination – Apple

All varieties of apple trees require some cross-pollination for fruit set. Even though some varieties are listed as self-fruitful, they will set fruit more heavily and more regularly if they are cross-pollinated. Flowering crabapples (see variety list below) have become popular pollen donors because they generally have longer bloom times than apples and are easily cared for.
