This 1/4" caliper rootstock is a slightly dwarfing, widely adapted seedling of Myrobalan plum. Used as rootstock for plums and can also be used for almonds. Considered a vigorous or semi-vigorous rootstock, producing a tree with a mature height of 16ft - 20ft. Like most seedling rootstocks, Myrobalan is not particularly precocious, and trees should start bearing after 4-5 years. More tolerant of wet soils than peach rootstocks Lovell or Nemaguard. Very good anchor roots from an early age, and not much suckering.
Usually good resistance to armillaria root rot and nematodes, but seedlings can be variable.
LIGHT, WATER, SOIL, FERTILITY NEEDS:
Full sun, balanced moisture, reduce grass competition in root zone. Top dress with compost yearly. Will need regular summer water in dry regions. Benefits from staking in first few years in windy locations.
16-20' x 18'
From France, pre-1910
Depends on scion wood
Summer prune for airflow, height and ease of harvest. Can sucker vigorously in stressful locations.
Seedlling rootstock retards maturity of tree - 3-4 yrs until produces first fruits.
Makes a large semi dwarf tree if unpruned but can be maintained at any height with summer pruning. Good anchorage.
