Strawberry

Strawberry is grown across a wide range of climates, from short-season perennial plantings in cooler regions to intensive annual plasticulture systems in milder climates that allow multiple harvest windows or off-season production.

Cultivars are commonly grouped by their flowering response to day length, including short-day (June-bearing), day-neutral, and everbearing types, which growers select to match their local season and target harvest window.

Family

Rosaceae (rose family)

Genus

Fragaria

Principal species

Fragaria × ananassa, an octoploid hybrid of Fragaria virginiana and Fragaria chiloensis

Growth habit

Low-growing perennial herb spreading by stolons (runners), propagated vegetatively

The modern garden strawberry arose in 18th-century Europe from the accidental crossing of Fragaria virginiana, native to eastern North America, and Fragaria chiloensis, native to Chile and the west coast of the Americas, producing a hybrid with notably larger fruit than either parent.

Strawberry is now cultivated commercially across temperate and subtropical regions worldwide.

Flowering in many strawberry cultivars is triggered by day length and temperature, with short-day types initiating flowers under shortening autumn days and day-neutral types flowering largely independent of day length.

Spring frost during bloom can damage or destroy flowers, and in some production regions, overhead sprinkler irrigation is used specifically to protect blossoms from frost through the release of latent heat as applied water freezes.

Strawberry prefers well-drained, sandy loam soils with good aeration and a slightly acidic pH, reflecting its relatively shallow, sensitive root system.

Strawberry is propagated from runners or, increasingly, from certified plug plants, and established either as an annual planting on plastic-mulched raised beds (plasticulture) or as a perennial matted-row planting that crops over multiple seasons.

• Cultivar selection matched to day-length response and target harvest window
• Use of certified, disease-tested planting material
• Plasticulture systems for annual production versus matted-row systems for perennial cropping
• Row spacing and plant density set according to the chosen system

Nitrogen supports vegetative growth but is managed carefully, since excess nitrogen can promote soft, disease-prone foliage and fruit at the expense of quality. Potassium and calcium both influence fruit firmness and shelf life.

Strawberry has a shallow root system and benefits from frequent, relatively light irrigation to maintain even soil moisture, particularly during establishment and fruit development. Drip irrigation under plastic mulch is standard in most intensive commercial systems.

Overhead sprinkler systems are used in some regions both for irrigation and, as noted above, for frost protection during bloom.

Gray mold (Botrytis fruit rot) is one of the most damaging diseases of strawberry, affecting flowers and ripening fruit, particularly in humid or wet conditions. Powdery mildew affects leaves, flowers, and fruit and can be severe in warm, dry climates. Spider mites and thrips are common pests affecting foliage and fruit quality.

Management combines resistant or tolerant cultivars where available, canopy and irrigation management to reduce humidity around fruit, monitoring, and — where justified — locally authorized control products applied according to their labels.

Strawberry fruit ripens rapidly and does not continue to ripen after picking, so harvest is done by hand at full color, often every one to three days during the peak season to keep pace with ripening. Rapid cooling after harvest is important given the fruit's high perishability.
