Pollination Info for Santa Rosa Plum Tree (Prunus salicina 'Santa Rosa')

The Santa Rosa plum tree is a self-fertile, meaning it can produce fruit on its own without needing another tree for pollination. However, having a second plum tree nearby can increase fruit production. This is because plum trees are primarily pollinated by bees and other pollinators, which are attracted to the fragrant flowers of the tree.

If you choose to plant another plum tree near your Santa Rosa plum, make sure it is a compatible cultivar. The best pollinators for the Santa Rosa plum tree include other Japanese plum varieties, such as Burgundy, Beauty, or Ozark Premier. Avoid European plum varieties as they may not be compatible for cross-pollination with the Japanese plum.

Planting your Santa Rosa plum tree near other flowering plants can also attract pollinators to your garden. Be sure to provide a diverse range of flowers that bloom throughout the growing season to keep them coming back. Additionally, avoid using pesticides that can harm bees and other beneficial insects.
