Strawberry 'Sparkle'

Strawberry ‘Sparkle’ (Fragaria × ananassa ‘Sparkle’). is an heirloom, June-bearing variety introduced by Rutgers in 1942. This vigorous and productive selection yields a late mid-season to late harvest. Its deep red strawberries, generally medium-sized, are known for their pronounced aroma, juicy flesh, and excellent flavor. Their rather tender texture requires delicate picking and handling, while their remarkable taste is particularly suitable for jams, preserves, and freezing. The plant produces many runners and easily forms a matted row when given sufficient space.

Plant ‘Sparkle’ in full sun in soil rich in organic matter, loose, cool, and perfectly drained, ideally slightly acidic. Place the crown exactly at ground level and space plants 35 to 45 cm (14 to 18 in) apart. Guide a few runners to renew the row or remove them to maintain distinct plants. Water regularly at ground level during flowering and fruit development. A layer of clean straw limits splashing, keeps strawberries off damp soil, and slows evaporation. However, avoid standing water and excessive nitrogen applications.

Harvest fruits when they are entirely deep red, preferably in the morning when the foliage is dry. Their tender texture requires shallow containers and rapid refrigeration. Size may decrease as the harvest progresses, but the picking period remains relatively long for a June-bearing strawberry. Hardy to Zone 3, ‘Sparkle’ benefits from winter protection with straw after several light frosts. After harvest, renovate established rows without injuring the crowns. Monitor for gray mold and foliar diseases, start with healthy plants, and avoid replanting immediately in a plot affected by root diseases.
