Apple Rootstock and Pollination Information
Apple Rootstocks
DWARF G-41
Tree will grow 6′-9′. Precocious and productive. Resistant to fireblight and replant disease. Permanent support required. Space 6′-8′ apart.
DWARF M-26
Trees will grow 7′-12′ and are very productive and cold hardy; will not tolerate poorly drained soil. Requires staking in early years and may require permanent support in some situations. Space 7′-9′ apart.
SEMI-DWARF M-106
Trees will grow 10′-15’and produce a well anchored root system. Trees are precocious and productive, tolerating a wide range of soil conditions. Very cold hardy. Should be staked in early years. Space 10′-15′ apart.
Apple Pollination
Apples and Pears need close attention to matching bloom times for good fruit set. In our cool spring climate, we have extended bloom times; other climates with warm springs may have more compressed bloom seasons that allow more pollinizer choices. The charts below are based on our experience in the Pacific Northwest; contact your local Master Gardeners or county agricultural extension agent for information about bloom times in your area.
Apple Bloom Times
- Choose your pollinizer from the same or adjacent group. For example, apples from GROUP 2 will pollinize varieties from GROUP 1, 2 or 3. GROUP 3 will pollinize GROUP 2,3 or 4.
- Varieties marked with an asterisk* do not work as pollinizers for other varieties (they have sterile pollen).
- Varieties marked with a caret^ are partially or fully self-fertile, but planting with a pollinizer may increase crops.
- Bloom time does not correspond to ripening time. Choose varieties that ripen at different times to spread out your harvest, and check to make sure you have appropriate pollinizers.
