Today the French prune plum tree are sought by connoisseurs around the world. The French Prune tree was introduced to the States by Pierre and Louis Pellier, brothers who went to California for the Gold Rush, started a nursery business near San Jose in 1856 with plum cuttings they brought from France. Prunes were almost as precious as salt and were used to bargain wages during the 15th century. From this uppermost bud, the new leader will emerge.Traditionally the French plum was dried and kept over a long period of time when refrigerators did not exist and winter meant months with few fruits or vegetables. Reduce the height of the leader by a foot or two, making your cut just above a bud. Cut right above the outermost bud that will remain. Reduce the length of each of the four scaffold branches by about half (but make sure each is left with at least a couple of buds). Together, they are said to comprise a "scaffold whorl," because they are primary (scaffold) limbs and form a circular arrangement of like parts. The "best" branches point upwards from the trunk at roughly a 45-degree angle, are well-formed and disease-free, and spaced at about an equal distance from each other on the horizontal plane (for example, think of a North-facing, an East-facing, a South-facing, and a West-facing limb).Įven on the vertical plane, these branches should not be too close together ensure 6 to 12 inches of space between them on this plane.
These are the ones you will keep, pruning off the rest almost all the way back to the trunk, leaving just the branch collar. Look over the plum tree and determine what its four best branches are at a level of about 18 to 24 inches up from the ground.
The next spring, you have three different pruning jobs to perform: Remove all but the best branches, shorten these "best" branches, and head back to the leader again. Create First Scaffold Whorl on the Plum Tree.The Spruce Home Improvement Review Board.
