High Yields: Despite their small size, M9 rootstocks encourage heavy cropping.
Large Fruit Size: M9 can enhance the size of the fruit produced.
Support Required: Due to their smaller root system, trees on M9 rootstock need support, such as staking or a trellis, throughout their lives.
Adaptability: M9 is adaptable to a range of soil types but prefers well-drained soil.
Widely Used: M9 is one of the most popular and widely planted dwarfing rootstocks worldwide.

Water and Nutrients: M9 rootstocks benefit from regular watering and fertilization, especially during dry periods.
Overall, the M9 rootstock is an excellent choice for anyone looking to grow apple trees in a limited space or who wants to maximize fruit production.
