Which combination describes the method used to dwarf fruit trees?

• A. Grafting onto standard rootstock
• B. Pruning only
• C. Budding or grafting onto a dwarfing rootstock
• D. Seed propagation

Answer: (C)

Dwarfing fruit trees comes from pairing the desired fruit variety with a rootstock that limits growth. By budding or grafting onto a dwarfing rootstock, the scion is attached to a plant whose root system and vigor are smaller, producing a compact, earlier-fruiting tree. This combination directly controls size, rather than just trimming it back or starting from seed.

Grafting onto a standard rootstock would not achieve dwarfed size, as the tree tends to grow to full vigor. Pruning alone can shape or slow growth temporarily but doesn’t change the tree’s inherent vigor. Seed propagation creates variability and usually does not preserve the original cultivar or produce a dwarf form.
