Description
The Malus domestica M9 is the most widely used and popular rootstock for apple trees worldwide. This weak to moderately vigorous rootstock is ideal for intensive fruit cultivation and is often used in orchards and compact gardens. Apple trees grafted onto an M9 rootstock remain relatively small, which makes them perfect for limited spaces and easy maintenance.
Key features:
Vigor: The M9 rootstock reduces the vigor of the tree to 40% of a seedling, resulting in trees that are approximately 1.8 to 2.5 meters tall.
Suitable for intensive cultivation: Due to the compact growth, trees on an M9 rootstock can be planted close together, with a recommended planting distance of 2 to 3 meters.
Early fruiting: This rootstock stimulates an early harvest; the first apples appear from the second year after planting.
Fruit Quality: M9 promotes uniform fruit size and color, making the variety ideal for commercial fruit production.
Support: Permanent support, such as a stake or pole, is essential for stability due to the weaker root structure.
Applications:
The M9 rootstock is perfect for growing:
Small apple trees such as spindle trees, bush-trained trees and oblique cordons.
Gardens and orchards with limited space.
Versatile apple varieties as this rootstock is compatible with most varieties.
Care:
The M9 grows best in fertile, well-drained soil. Provide adequate nutrition to keep the tree healthy and plant in a location that can withstand moderate winters. Avoid extremely cold climates as the rootstock can be sensitive to severe frost.
Conclusion:
The Malus domestica M9 is the standard in fruit growing and offers an excellent basis for healthy, productive apple trees. Ideal for both the professional grower and the hobby gardener.
