| Description |
St Julien is the most widely-used rootstock for plums in the UK. Semi-dwarf rootstock for cold areas with fluctuating spring temperatures due to inconsistent spring weather conditions. Preferred over Citation in north coastal mountains and Oregon. It is a semi-vigorous rootstock, roughly equivalent to the apple MM106 roostock in the size of tree it produces - although in good soils and in good climates (with good sunshine and rainfall) it can be somewhat more vigorous. It is compatible with almost all plums and gages. Plum trees grown on St. Julien rootstocks tend to come into bearing after 3-4 years. They can be used to produce free-standing trees (with no staking required once established) and are also ideal for large fans for wall-training - a format which is particularly suitable for plums in more northerly latitudes. A mature fan will be 3m-5m across and 3m or so high.
St. Julien is suitable for a wide-range of soil conditions, with some tolerance of chalky soils. |
