shrubRed Prince is a cold-hardy, everbearing red raspberry cultivar that produces fruit on both primocanes (first-year canes) and floricanes (second-year canes), allowing for summer and fall harvests.

The plants grow as upright, thornless or nearly thornless canes reaching 4-6 feet tall.

Establishment Year 1
Spring to fallYoung canes emerge from ground with 3-5 leaflets per leaf; plants focus on root and cane development
Remove flowers in first year to encourage vegetative growth; keep well-watered and mulched; prune out weak canes
Primocane Flowering & Fruiting (Summer-Fall Year 1)
6-8 weeksSmall white flowers appear on new canes in mid-summer; red berries develop and ripen by early fall
Thin canes to 4-6 per plant for better air circulation; harvest ripe berries regularly to encourage more production
Floricane Flowering & Fruiting (Summer Year 2)
4-6 weeksSecond-year canes produce abundant white flowers in spring, followed by medium to large bright red berries
Provide sturdy support; thin canes if overcrowded; fertilize after harvest begins
Post-Harvest Maintenance
Fall through winterCanes that fruited are cut down to ground level; healthy new canes continue growing
Remove all canes that have fruited to prevent disease; leave 4-6 healthiest new canes per plant; apply winter mulch in cold zones
Dormancy
November to MarchCanes enter dormancy in late fall/winter; plant appears brown or bare
Maintain winter mulch; prune out any dead or diseased canes on warm days; ensure good drainage to prevent ice damage

Harvest Tips
Harvest berries when fully red and slightly soft, usually in early morning when temperatures are cool. Red Prince produces two harvests: early summer (floricanes) and late summer through first frost (primocanes). Gently pull ripe berries; they should detach easily from the receptacle. For maximum fall production, some growers cut all canes to the ground in early spring, sacrificing the summer crop but obtaining a larger, concentrated fall harvest.
Fun Facts
- 🌱 Red Prince is one of the most cold-hardy red raspberry cultivars, surviving winters as far north as zone 3a, making it ideal for Canadian and northern US gardens.
- 🌱 The variety produces fruit twice per season: on new canes (primocanes) in late summer/fall and on year-old canes (floricanes) in early summer, providing an unusually long harvest window.
- 🌱 Red Prince berries have exceptional flavor for a cold-hardy variety, with a perfect balance of sweetness and tartness that makes them superior for both fresh eating and preserves compared to many other hardy cultivars.
