PruningApricot, Prunus armeniaca -
WHY Pruning of the Apricot is quite similar to that of the Plum. The fruit-buds are borne on spurs, as the Apple, or on the wood of the previous season's growth, either terminal or lateral. Before pruning a variety learn the habit of fruit-bud formation. If the variety is unknown to you, then study new growth and observe where the flowers develop. The fruit-bud is easily recognized; it is much larger in size than the wood-bud. In most varieties of Apricot the long slender shoots that grow during the summer months will bear the fruit the following season, but the location of the fruit-bud on the slender shoot is characteristic of the variety. Heavy pruning is necessary to produce good fruit.
Apricot trees tend to spread excessively, so thin to upright wood.
Apricots bear laterally on spurs that usually live for no more than three years. Annually thin bearing trees to upright shoots. Thinning renews fruiting wood and improves light distribution. Don't head remaining branches unless branches are excessively long. Head long branches lightly to contain them.
