Rochester Peach Tree
Rochester Peach Tree is a yellow-fleshed dessert peach, valued for being one of the largest peaches.[1] [2] It develops late, dark pink spring blossom, meaning frost issues are considerably less than most other peach trees. It is self-fertile meaning it produces fruit without the need of another peach tree nearby, however if you notice limited to no flying buzzies during flowering time, consider hand pollination. [1] [6]
Rochester is historically classed as a freestone peach, meaning the flesh separates more easily from the stone than with a clingstone peach. An interesting detail from early records is that it could show slight clinging in some conditions, so stone separation can vary slightly with ripeness and growing conditions. [8]
The skin is orange-flushed red with yellow flesh inside, a soft juicy texture and very good flavour. Rochester usually ripens in August, often around mid to late August depending on site, season and sunshine. Pick the fruit while still firm, ripen indoors if needed, and chill ripe peaches to slow deterioration before eating promptly. [1] [2] [9]
We supply Rochester as St Julien A rootstock. As a peach on a semi-vigorous rootstock, it is best planted in the ground rather than kept long term in a pot. It can reach around 4–5m depending on pruning, training and growing conditions, but can be managed as a bush or trained as a large fan against a sunny wall or fence. [4] [5]
It has been recognised by the RHS with an Award of Garden Merit and is included by the RHS among its recommended top fruit for gardens. [2] [3]
For the best results, grow Rochester as a fan-trained tree [2] [6] [7] against a south-facing or west-facing wall or fence, but warmer parts of the UK e.g. Midlands and below can grow them as a free-standing bush or tree.
If you want to store them rather than eat them fresh, pick Rochester peaches while still firm. For normal home use, let them finish ripening at room temperature in a cool, dry place out of direct sun, then chill ripe fruit in the fridge to slow deterioration. Bring chilled peaches back towards room temperature before eating for the best flavour. [9]
Planting Rochester Peach Trees
Plant Rochester Peach Trees in full sun, in fertile, moist but well-drained soil. Avoid north-facing walls, exposed windy sites, frost pockets and ground that becomes waterlogged. Good drainage matters more than the exact soil type. [2] [6]
Avoid planting during hot, dry weather, frozen ground or waterlogged conditions. Plant at the same depth as the tree was growing in its pot, firm the soil gently around the roots and water well after planting. [6]
If planting as a fan, prepare horizontal support wires before the tree becomes difficult to train. Plant it away from the base of the wall rather than tight against it, and improve dry wall-side soil with organic matter before planting. Fan-trained peaches may need extra watering because walls and fences can create a rain shadow. [6]
Keep the area around the base clear of weeds and grass while the tree establishes. Mulch with well-rotted organic matter to conserve moisture, but leave a small gap around the trunk so the bark does not rot. Water regularly during dry spells for the first couple of years, especially when the tree is carrying fruit.
Rochester Peach Leaf Curl
Peach leaf curl is the main disease to plan for. It is encouraged by wet conditions as the buds and young leaves open, so prevention is based on keeping young spring growth dry during the risk period. RHS notes that some resistance is claimed for Rochester, but protection is still recommended. A temporary rain cover from winter into spring is especially useful on fan-trained trees and other forms. [7]
Rochester Peach Frost Protection
Because peach blossom is vulnerable to frost, cover the tree overnight with horticultural fleece, hessian or a similar breathable material if frost is forecast while it is in flower. It should tolerate temperatures down to minus 1 degree centigrade, anything lower than that and blossom damage starts to happen. Keep the cover from resting directly on the blossom and remove it during the day so light and pollinating insects can reach the flowers. [6]
Rochester Peach Fruit Thinning
When young fruits reach roughly hazelnut to walnut size, thin crowded clusters so the remaining peaches are spaced about 20cm apart. This helps the tree put its energy into fewer, better-sized fruits and reduces the risk of branches being overloaded. Prune peach trees in spring or summer only, not in winter, because stone fruits are more vulnerable to silver leaf and bacterial canker when pruned in cold, wet conditions. [6]
Interesting Information About Rochester Peach Trees
It originated in New York State from a seed planted around 1900 on a farm owned by Mr Wallen near Rochester, New York. It was later introduced by Heberle Brothers Nurseries of Brighton, New York, in 1912. [8]
Old American pomological records describe Rochester as part of the Crawford group of peaches, a famous line of yellow-fleshed peaches valued for appearance and flavour. The same records described Rochester as large, yellow, red-blushed, juicy, sweet and highly flavoured, with a season that could stretch over a useful picking period rather than ripening all at once. [8]
Department of Agriculture storage bulletin lists Rochester with a storage life of about 21 days at 32°F, which is roughly 0°C, under controlled cold-storage conditions. That should not be read as a promise that ripe garden-picked peaches will keep for three weeks at home: peaches still lose quality if stored badly or too long, and problems such as poor flavour, mealiness or breakdown can develop.
