Hybrid / Siberian plums

Plum rootstocks:
Here are the characteristics of rootstocks, ranked from those that slow growth the most to those that are the most vigorous:

Saint Julien A
Ensures compact, moderately weak growth suitable for smaller orchards. Promotes early and abundant harvests, increases the tree's frost resistance, and tolerates wetter soil conditions well.

Mirobalan C5
Compared to common seedlings, it produces more balanced growth and earlier fruiting. It tolerates drier and poorer soils well, while positively influencing fruit size.

Caucasian plum
Extremely vigorous and undemanding in terms of soil conditions. Thanks to its strong and deep root system, it anchors well, resists drought, and ensures the longevity of trees.

Myrobalán
Ensures very vigorous growth and longevity of trees. It is extremely undemanding, adaptable to almost all soil types, and provides excellent stability without the need for support.
