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.
