Pollination & Compatibility Guide
Harry Masters' Jersey apple pollination guide: diploid bittersweet cider apple, late bloom group 5. Compatible partners and cider orchard notes.
Harry Masters' Jersey is Self-Sterile (Needs 1 Partner)
Harry Masters' Jersey needs at least one compatible pollinizer from bloom group 4–6 to set a reliable crop.

Flowering Period & Overlap Window
Apple flowering periods are classified into numbered bloom groups (1 through 6). A variety reliably cross-pollinates with cultivars in its own group or adjacent groups (±1 group).
Any compatible diploid apple flowering within Group 4 to 6 provides matching blossom overlap.

Incompatible Varieties & Exclusions (6)
These varieties overlap in flowering time with Harry Masters' Jersey but cannot fertilise it due to sterile pollen (triploids) or shared genetic incompatibility alleles.
Arkansas Black produces no viable pollen, so it cannot serve as a pollinizer.
Ashmead's Kernel produces no viable pollen, so it cannot serve as a pollinizer.
Jonagold produces no viable pollen, so it cannot serve as a pollinizer.
Orleans Reinette produces no viable pollen, so it cannot serve as a pollinizer.
Stayman Winesap produces no viable pollen, so it cannot serve as a pollinizer.

Grower Commentary: Harry Masters' Jersey Late Bloom and Tannin
Harry Masters' Jersey is a vintage bittersweet cider apple of Somerset, a seedling of unresolved parentage, so no named cultivar is excluded by descent. Our record treats it as diploid and self-sterile, but diploid is the species default here, not a measurement, so confirm with your nursery. It flowers late, in bloom group 5, with viable pollen.
Late bloom helps it miss many spring frosts, but it also narrows the partner choice. Only the latest-flowering cider apples overlap well, so pair it with other group 5 or group 4 cultivars and keep a bloom diary for the first seasons. Harvest falls at about the same time as Golden Delicious in maritime north-west European conditions.
The record lists cider as its use. The fruit is bittersweet, with firm tannin that gives body and structure to a blend. Standard and half-standard trees suit grass alleys and grazed orchards, while bush trees on a semi-vigorous rootstock crop sooner. Thin heavy sets to keep fruit size and next year's buds in balance.
Key Orchard Considerations for Harry Masters' Jersey
Use a semi-vigorous rootstock for bush trees, or standards for grazed cider orchards.
Late bloom dodges frost but limits partners; check overlap each year.
Bittersweet tannin suits blends; pick ripe and press in a mixed cider batch.
