CONT: Fruit trees generally do not set fruit well unless pollinizing trees are provided. For fruit to set, the trees must bloom and the flowers must be fertilized by pollen. Only a few cultivars are self-fertile, that is, capable of fertilizing the ovaries of their own flowers with their own pollen. Most are self-sterile and must have pollen from another cultivar for fertilization to take place. Some are partly self-fertile and set a few fruits, but compatible pollinizers are needed to get good yields.
