Methley Hybrid Plum
Pollination & Compatibility Guide
Methley plum pollination guide: self-fertile Pool B status, early Group 2 bloom and Japanese plum donor use.

Flowering Period & Overlap Window
Plum bloom groups run from 1 to 5. A useful partner flowers in the same or adjacent group and belongs to the same pollination pool. European plums, gages and damsons are Pool A; Japanese plums and prairie hybrids are Pool B. A tree from one pool cannot pollinate the other.
For Methley, select a compatible plum in the same pollination pool flowering from Group 1 to 3; bloom overlap alone does not bridge Pool A and Pool B.

Incompatible Varieties & Exclusions (11)
These cultivars cannot serve as pollinizers for Methley because of a different plum pollination pool, a documented incompatibility or another exclusion in the source data.

Grower Commentary: Methley as a Pool B Donor
Methley is a self-fertile Pool B hybrid and one of the most useful pollen donors in Japanese plum plantings. It flowers in Group 2, so Shiro, Santa Rosa and other early Pool B cultivars are candidates where the open-bloom days coincide. Methley can carry its own crop, but it cannot pollinate European plums, gages or damsons in Pool A, regardless of how close the rows stand.
The first planning risk is the very early bloom. A low corner of a block can lose flowers to frost before bee activity begins, leaving a donor tree present on the map but ineffective in practice. Walk the site on cold mornings, preserve downhill air movement and compare flowering dates across several seasons. One early donor cannot cover a companion whose blossom consistently opens well after Methley finishes.
Methley can be integrated as a bearing pollinizer row rather than an unproductive pollen source. Keep the canopy open and manage crop load so branches carry sound fruit without excessive bending. Citation may suit a well-drained site, but its water-stress behaviour makes irrigation and soil choice important; a wetter site calls for a different stock. Check scion compatibility and local nursery advice before fixing the final block design.
Key Orchard Considerations for Methley
Self-fertile Group 2; useful for overlapping Japanese plums, never for Pool A European cultivars.
Avoid frost pockets and verify that the companion opens flowers during Methley's actual bloom.
Leave light and picking access, and match the rootstock to drainage and irrigation.
