Cultivating a commercially viable cherry crop has many components. First, the soil pH and nutrients must be tested frequently (generally by a state university extension service) so that foliar fertilizers meet the requirements of the trees. Generally, growers keep a record of these soil tests. Second, the grower must understand the climate and soil types well enough to choose a rootstock that will flourish in that area. Third, pesticides or insecticides must be very carefully mixed and applied according to the U.S. Environmental Protection Agency (EPA) standards, recommendations of state university extension services, and the product label. Fourth, pollination of the cherry blossoms is absolutely imperative; if there are few bees in the area, growers must rent bees for this purpose. Fifth, the trees must be carefully shaken during harvesting (if the cherries are to be harvested) so that the tree is not irreparably damaged. Finally, vigilant pruning and assessing the amount of air and sunlight densely packed trees receive is imperative for large yields.
