Apple Rootstock and Pollination Information
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 columns. For example, Idared pollinizes Williams Pride (Same column) or Akane (Adjacent column), but not Elstar. Varieties marked with an asterisk* do not work as pollinizers for other varieties (they have sterile pollen).
