As a general rule amateurs and home-growers of the domestica plums and peaches never think of thinning the fruit, even in seasons when the trees are carrying double loads. The commercial growers also are more apt to neglect fruit-thinning than any other part of the work. Yet no work of the orchard pays in dollars and cents better than fruit-thinning, especially of the foreign plums and the peach. The thinning should be deferred until after the usual drop of the fruit in June, when it is as large as marbles. The peach and domestica plums should be thinned so that no two will touch each other when of full size, and experienced growers thin so closely that those left are from four to six inches apart, depending on the strength and leafage of the branch. Some of the gains of thinning are that it favors annual bearing, the fruit is less liable to the attack of rot, and if methodically packed the fruit sells at a much higher price.
