About These Tolerant Rootstocks
Plum rootstocks are tolerant of a wide variety of soil conditions. With the Mariana 2624 plum rootstock, peaches, plums, almonds, nectarines and apricots can be grafted on the same tree. Peaches won't usually take with winter grafting. They need to be budded in the summer.
Plum Rootstock Propagation
Easily done by hardwood cuttings in the fall or early winter. Sometimes stoolbeds are used. For cuttings, use pencil size new wood and cut about 10 inches long. Using bottom heat will increase success but they will root if just stuck in the field. Peach rootstocks are usually grown from seeds.
