These branches will be replaced with growth from the inside of the tree. Apricot wood is brittle so you should not allow any one branch to spread a great distance. Favor erect growth whenever possible and sacrifice early fruit production for sturdy framework. So you most select the lateral branches as describe above during the first growing season. During the summer select two more well spaced shoots on each of the framework or scaffolding branches.
Sweet Cherries are very tall growers and are inclined to develop weak crotches.
The over all shape should be that of a funnel. The open center permits better ripening of the fruit. Fruit is borne on one year old wood and not on spurs, so the fruiting wood must be renewed each year. Although they flower along the entire length of a branch, The only flowers you should let set fruit are those in the center one third section. After you have thinned the tree you should cut back these twigs about a third of their length.
