Caroline Raspberry Shrub (Rubus idaeus ‘Caroline’) is a vigorous, everbearing variety prized for its large, deep red berries with exceptional sweet-tart flavor. Known for its extended harvest season, Caroline produces heavy summer crops followed by an abundant fall harvest, making it one of the most productive raspberries for home gardeners. The berries are aromatic, juicy, and versatile—perfect for fresh eating, freezing, baking, or preserves. Hardy and disease-resistant, Caroline Raspberry is an excellent choice for edible landscapes, berry patches, and backyard gardens.
Growing Caroline Raspberry Shrub
Light: Requires full sun for best yields, fruit size, and flavor.
Soil: Thrives in well-drained, fertile soil; enrich with compost or organic matter for strong production.
Water: Keep soil consistently moist, especially during berry development. Mulch helps retain moisture and control weeds.
Fertilizer: Apply a berry or balanced orchard fertilizer in early spring and midsummer to promote strong cane growth and fruiting.
Pollination: Self-fertile; produces well without another raspberry variety for pollination.
Maintenance: Prune in late winter to remove old canes and thin weaker shoots. Can be maintained as a primocane (fall-bearing) or Floricane (summer-bearing) crop with proper pruning methods.
Hardiness: Best grown in USDA zones 4–8. Produces consistent harvests in summer and again in fall.
