Harvesting Peach

Peaches have moderate water needs but require consistent moisture during fruit development from late spring through summer. Water deeply once or twice a week in dry spells, soaking the root zone rather than sprinkling the leaves. Reduce watering after harvest and in winter, but don't let the soil dry out completely, especially for trees in containers or against walls where rain doesn't reach. Feed in March with a balanced general fertiliser such as blood, fish, and bone, scattering a generous handful around the root zone and lightly forking it in. Apply a second feed in June using a high-potash tomato fertiliser to support fruit ripening and next year's flower buds. Mulch annually in spring with well-rotted compost or manure to suppress weeds, retain moisture, and slowly release nutrients. Peach leaf curl is the most serious problem in temperate Europe, causing red blistering on leaves in spring and weakening the tree. The fungal spores infect during winter and early spring, so prevention is key: cover trees with a clear polythene shelter from January to May to keep rain off the foliage, or grow in a greenhouse. Remove and destroy infected leaves promptly. Aphids can cluster on soft shoot tips in late spring; squash by hand or spray with an organic insecticide if necessary. In colder zones, protect blossom from late frosts with horticultural fleece draped over the canopy on cold nights. Thin fruitlets in late May or early June to one peach every 15–20 cm along each shoot; this prevents branch breakage and ensures larger, sweeter fruit. Peaches are self-fertile, so a single tree will crop, but hand-pollination with a soft brush during flowering improves fruit set in cool springs.
