Peach Tree

Peach (Prunus persica) is a deciduous fruit tree native to Asia, and many cultivars give either peaches or nectarines. The tree can grow 15 to 25 feet (457 to 762 cm) tall and wide, with showy flowers in spring and fruit in summer. It needs regular pruning and pest control to keep a strong structure and produce fruit.

For a beginner, this is a demanding plant. Growing it well takes ongoing work, and the sources note that results can be inconsistent in cold climates.

Peach trees are usually planted as grafted trees rather than started from seed. Seed can be sown in containers outdoors in autumn, but also that peach cultivars are propagated by grafting. Growing a tree from a pit is possible but not recommended, because peaches do not come true from seed and the tree may have inferior fruit and may not be reliably winter-hardy.

Plant in early spring or fall. Choose a site in full sun, with at least 8 hours of direct sun, in moist but well-drained soil. Peaches can be prone to iron chlorosis on heavy clay soils, so good drainage matters. Space trees 12 to 16 feet (366 to 488 cm) apart; Iowa guidance gives about 15 feet (457 cm) for standard trees. Most cultivars are self-fruitful, but a few, such as J.H. Hale, need a different peach tree within a few hundred yards for pollination.

Watering. Peach trees need about 30 inches (76 cm) of water over the growing season. Water deeply and less often, using drip lines, soaker hoses or hand watering, and avoid sprinklers. Keep a ring of mulch around the base to conserve moisture and reduce weeds.

Pruning. Peaches bear fruit on one-year-old wood, so annual pruning is essential. Prune during the dormant season, usually in February or March; Iowa guidance recommends early spring before bud break.

Thinning. When the spring weather allows a heavy set, remove excess fruit soon after fruit set so the remaining peaches are about 6 to 8 inches (15 to 20 cm) apart along the branches.

Peaches are subject to many pests, including peach tree borer, plum curculio, oriental fruit moth, root nematodes, mites and aphids. Very cold winters and late spring frosts often damage buds and flowers. Iowa guidance notes that flower buds can be damaged near -11 °F (-24 °C). Diseases can include peach leaf curl, powdery mildew, scab and brown rot, and gardening experts also lists bacterial canker, blossom wilt and silver leaf as possible problems.

Peaches ripen in mid to late summer, depending on the cultivar and the weather. Look for the ground color to change from green to cream or light yellow, because the red blush is not a reliable sign of ripeness. Ripe fruit is slightly less firm, and you can check by gently squeezing it. Handle fruit carefully to avoid bruising.

Peaches do not store well, so use them soon after harvest. Store them at 32 °F (0 °C) and 90-95% humidity; they keep for 2 to 3 weeks. For longer storage, freezing, canning and drying are options.

Pets. Pet poison experts list peach as toxic to dogs and cats, and to horses. Stems, leaves and seeds contain cyanide compounds, which are especially toxic when the plant is wilting. Keep dogs, cats and horses away from fallen or wilted branches and leaves.

People. The fruit is edible raw or cooked. Discard the pit: it contains hydrogen cyanide and should be thrown away. Don’t crush or chew the pits, and don’t blend unpitted fruit into smoothies. Wilted leaves are poisonous, especially if eaten in quantity, so don’t eat them.
