Cherry Tree

Select a site with full sun and excellent drainage, as cherry trees are highly sensitive to waterlogged soil and root rot. A gentle slope with good cold air drainage helps protect early blossoms from late frosts. Avoid heavy clay soil or amend it thoroughly with compost and coarse organic matter. Space sweet cherry trees 25 to 30 feet apart and sour cherry or dwarf types 12 to 15 feet apart.

Plant bare-root cherry trees in late winter or early spring while dormant. Dig a hole wide enough to spread roots without bending. Set the graft union 2 inches above soil level and water deeply at planting. Mulch with 3 to 4 inches of wood chips, keeping mulch away from the trunk. Water weekly during the first growing season, providing 1 to 2 inches per week.

Prune cherry trees in midsummer after harvest rather than in winter to reduce the risk of bacterial canker and silver leaf disease entering through pruning wounds. Train sweet cherries to an open center or modified central leader and sour cherries to an open vase shape. As fruit approaches ripeness, cover trees with bird netting to prevent significant crop loss to birds.

The sweet cherry tree (Prunus avium) originated in the temperate deciduous forests between the Black Sea and the Caspian Sea, in a region spanning modern-day Turkey, Georgia, Armenia, and northern Iran. Wild Prunus avium trees still grow naturally across this area and throughout much of Europe, from the British Isles east to the Caucasus and from Scandinavia south to the Mediterranean mountains. Archaeological excavations of Neolithic and Bronze Age settlements across Europe have revealed cherry stones in hearth deposits and refuse middens, confirming that humans have collected and consumed wild cherries for at least 8,000 to 10,000 years.

The Roman general Lucullus is traditionally credited with introducing cultivated cherry trees to Rome around 74 BC, bringing grafted specimens from the city of Giresun on the Black Sea coast of modern Turkey — known to the ancient Greeks and Romans as Cerasus. Most linguists trace the English word "cherry" through Old French cerise and Latin cerasus back to this place name. While wild cherries were certainly known throughout Europe long before Lucullus, Roman horticulture contributed the systematic selection of superior fruiting varieties and the deliberate spreading of cultivated orchards along military and trade routes into Gaul, Britain, the Rhine valley, and the Iberian Peninsula.

Through the medieval period, European monasteries became the primary centres of cherry cultivation and improvement. Monastic orchards preserved and refined selected varieties, and monks developed early techniques for preserving cherries in sugar, honey, vinegar, and alcohol. By the sixteenth century, dozens of named cherry cultivars were documented in European herbals and garden manuals, and cherry growing had become a commercially significant enterprise across temperate Europe.

European settlers transported cherry trees to North America in the early 1600s, and by the nineteenth century the Pacific Northwest of the United States — particularly Washington, Oregon, and parts of California — had been identified as offering near-ideal conditions for sweet cherry production. The combination of dry summers that minimise fruit splitting and fungal disease, fertile volcanic soils, cold winters with adequate chill hours, and access to irrigation from snowmelt rivers created the foundation of what is now one of the world's most productive cherry-growing regions. Washington State alone produces over half of the total United States sweet cherry crop. Today Turkey remains the world's largest cherry producer, followed by the United States, Uzbekistan, Chile, and Iran.

Cherry trees require well-drained soil with a pH of 6.0 to 7.0. Sandy loam is ideal, and heavy clay must be amended or avoided entirely. Apply a balanced fertilizer in early spring before bloom, using about 1/8 pound of nitrogen per year of tree age up to a maximum of 1 pound. Avoid excessive nitrogen, which promotes vegetative growth at the expense of fruit. Supplement with potassium if fruit color development is poor.

Sweet cherries are ready when fully colored and slightly soft to the touch. Taste-test a few cherries for sweetness before harvesting the whole tree, as cherries do not ripen further after picking. Cut cherries from the tree with stems attached using scissors to extend shelf life and prevent wound infections on the spurs. Sour cherries are picked when they have reached full color and pull away easily from the stem. Harvest in the morning when fruit is cool for best quality.

Fresh cherries keep for 5 to 7 days refrigerated. Do not wash until ready to eat, as moisture promotes mold. Cherries freeze exceptionally well: pit them, spread on a baking sheet to freeze individually, then transfer to freezer bags. Sweet cherries are delicious dried and rival raisins for snacking. Sour cherries are superior for canning in light syrup, making preserves, and baking into pies. Cherry juice can be pasteurized and stored for months.

Sweet cherries are best enjoyed fresh, in salads, or dipped in chocolate. Sour cherries are indispensable for classic cherry pie, cobbler, and clafoutis. Cherries pair well with almond, dark chocolate, balsamic vinegar, and game meats like duck. They are rich in anthocyanins and melatonin, both with documented health benefits. Dried cherries add tartness to grain salads, trail mix, and baked goods.
