Rainier Pollination Guide

Rainier requires a compatible pollination partner to produce fruit.

Needs Pollinator

Without a different compatible variety nearby, Rainier will bloom but won't set fruit. You need at least one partner variety planted within 50–100 feet. Choose from the compatible varieties listed below — they bloom at the right time and have compatible genetics.

Pollination Note

S1S4 genotype — compatible with Bing (S3S4). Stella and Lapins are universal pollinators.

Planning Your Orchard

For sweet cherry pollination, the easiest approach is to plant a self-fertile variety like Stella or Lapins alongside Rainier. These "universal donor" cherries can pollinate any other sweet cherry. Space cherry trees 20–30 feet apart. If space is limited, consider a multi-grafted tree with compatible varieties on one rootstock.

About Rainier

Rainier is the premium yellow-red cherry with delicate sweetness and lower acidity than dark varieties. It commands the highest prices at farmers' markets but is notoriously difficult to grow.

Growing Challenges

Birds devastate the crop (yellow color attracts them); extremely prone to rain cracking and brown rot.

Frequently Asked Questions

Is Rainier self-fertile?

No, Rainier requires a compatible pollination partner. Self-fertile varieties like Stella and Lapins are the easiest partners — they can pollinate any sweet cherry variety.

How close does a pollinator need to be to Rainier?

For reliable pollination, plant the partner variety within 50–100 feet of Rainier. Bees are the primary pollinators and typically work within this range. In practice, a tree in your yard or even a neighbor's nearby tree can work. The closer the trees, the more consistent the fruit set.

Can I grow just one Rainier tree?

No — Rainier requires a compatible pollination partner to produce fruit. Without a second tree of a different variety nearby, it will bloom but won't set fruit.
