A letter of inquiry sent to representative nurserymen in all parts of the United States as to the relative merits of the several stocks for the different species of plums shows that plum propagators in different regions use somewhat different stocks. In New England and the North Atlantic States, the Myrobalan seems to be almost the universal choice, the exception being a few propagators who claim that the Japanese sorts should be worked on the peach, especially for sandy soils, and a few others who are using Americana stocks for the American species. In the Atlantic states south of Pennsylvania and in the Gulf states to the Mississippi the preferences are very diverse, with the majority of the nurserymen in this region favoring the peach, Myrobalan following as a close second choice. For light soils it would seem that the peach is always to be preferred for this great region. The opinions expressed by the veteran plum-grower, J. W. Kerr of Denton, Maryland, on this subject are worth printing in full. He says: “In this locality for all varieties of the Domesticas that unite thoroughly with it, the peach is preferable as a stock. There are, however, a good many varieties of Domesticas that refuse to unite firmly with the peach. For these the Marianna or the Myrobalan gives best results. For all of the Japanese plums the peach has proved most satisfactory, when the trees are propagated by root-grafting on the whole-root plan. Nearly forty years of experimenting and testing stocks of various kinds gives me a decided preference for the peach as a stock for native plums; results doubtless would be different in colder climates and soils than this, but long and critical experience has conclusively demonstrated the superiority of this stock when used as indicated for the Japanese.” In the interior region between the Atlantic and Gulf States and the Mississippi, the Myrobalan is used almost exclusively for the European plums and most largely for the other species. Several nurserymen from this region, however, state that the St. Julien is better than the Myrobalan for the Domesticas and Insititias but object to them because the stocks cannot be obtained as cheaply. The peach is generally recommended for the Triflora sorts and the statement is several times repeated that the Americanas would be preferred for the native species if stocks of this species could be obtained readily. In the northern states of the Mississippi Valley, all nurserymen agree that plums must be worked on Americana stocks. In this region the hardy natives only are grown.
