When you buy a grafted apple, peach, cherry or pluot, you're buying two plants working together. The scion is the upper portion that produces your chosen fruit. The rootstock forms the roots and lower trunk and helps determine how your tree grows.

Remember this: the fruit variety determines what you harvest; the rootstock helps determine how the tree handles its environment. Neither guarantees a fixed height, a harvest date, or disease immunity.

Why Rootstock Choice Matters

🌳 Tree size
Some stocks limit vigor; others produce larger trees.		 🌱 Soil adaptation
Root systems differ in tolerance for soil texture and certain stresses.
🛡️ Resistance
Some resist particular diseases or nematodes—not every problem.		 🍑 Time to fruit
Vigor and training affect establishment and early production.

These are relative growth descriptions, not promised mature heights. The same stock can behave differently with different grafted varieties and pruning systems.

Rootstock / tree type Growth What to know
M111 (MM.111)
Apple 		Semi-vigorous Larger than M7 in many settings; reliable anchorage, room to grow and annual training.
M7 (M.7)
Apple 		Semi-dwarf Usually smaller than M111; can sucker or require support, depending on site.
Geneva 935
Apple 		Dwarfing Size-controlling and productive; selected for resistance to certain diseases. Plan permanent support.
Nemaguard (Nem)
Peach & nectarine 		Vigorous Resists certain root-knot nematodes and prefers well-drained soil.
Lovell
Peach & nectarine 		Vigorous Adaptable peach stock, sometimes more tolerant of wet soil than Nemaguard, but not waterlogging.
Citation
Stone fruits 		Size-controlling Peach–plum hybrid; can reduce vigor and bring earlier production in compatible varieties.
Myro 29C
Plums & hybrids 		Vigorous Plum-based stock with tolerance for a range of soil textures; still requires drainage.
Mazzard
Cherries 		Standard / vigorous Produces substantial sweet cherry trees unless actively trained and pruned.
Maxma 14
Cherries 		Size-controlling Smaller than Mazzard in many settings; fruiting cherry still needs good drainage.
OHxF 333
Pears 		Size-controlling Old Home × Farmingdale pear stock; often near two-thirds standard vigor.

Note: “Maxma” without a number does not confirm Maxma 14. Persimmons, jujubes, some mulberries and any unnamed-rootstock trees require nursery confirmation before we promise rootstock traits.

Which One Fits Your Orange County Yard?

Small coastal gardens

Choose based on the variety's cold requirements, available light, pruning access and vigor, not the word “dwarf” alone. G.935 apples and Citation stone fruit may be options where their varieties and soil conditions fit. Consider permanent support for dwarf apples.

Large inland gardens

Where space and site conditions permit, M111 apples, Lovell or Nemaguard stone fruit, and Mazzard cherries may suit owners comfortable with larger canopies and seasonal pruning.

Clay soil or hillsides

Roots need oxygen. Even a stock marketed as more tolerant of heavy soils can decline under persistent waterlogging. Review slope stability, drainage, irrigation, wind exposure and staking before selecting the tree.

Multi-tree plantings

For close-spaced or three-in-one-hole orchards, compare relative vigor, overlapping pollination, harvest windows and a realistic summer-pruning plan. Rootstock compatibility and space limitations should be assessed before ordering.

The Graft Union: One Detail You Should Never Bury

Look for a slight swelling or angle just above the roots. That's typically the graft union. Keep it above the final soil grade. If shoots emerge from below the graft, remove them: they are rootstock growth, not the selected fruit variety. Keep mulch several inches off the trunk and protect exposed bare roots from drying until planting.
