Growth Stages
Establishment
12 monthsFirst-year canes develop root system and foliage; no fruit production expected
Water regularly, keep weeds controlled, apply 2-3 inches mulch, remove flower buds to encourage vegetative growth
Cane Development
Spring-early summer, 2-3 monthsSecond-year primocanes (new canes) grow vigorously while floricanes (second-year canes) prepare to fruit
Prune dead/damaged canes, thin primocanes to strongest shoots, install support trellising, maintain moisture
Flowering & Fruiting
May-August, 3-4 monthsFloricanes produce clusters of delicate white flowers that develop into green berries, gradually turning red
Support canes with trellising to prevent bending, apply balanced fertilizer, manage pests actively, thin fruits if desired for larger berries
Peak Harvest
June-August, 2-3 monthsBerries reach full red color and separate easily from drupelets; highest quality and sweetness
Pick ripe berries every 2-3 days, handle gently to avoid crushing, harvest in cool morning for best quality
Post-Harvest & Dormancy
September-November, 2-3 monthsFloricanes cease production and enter senescence; primocanes continue growth; plants prepare for winter
Remove and compost spent floricanes to ground level, continue watering until frost, apply winter mulch in zones 4-5
Common Pests
-
Use row covers pre-bloom, remove infested fruit, apply spinosad at bud break and petal fall, encourage natural predators
-
Prune out infested canes below entry holes, remove and destroy immediately, maintain plant vigor
-
Increase humidity with irrigation, spray with water to dislodge, use miticide if severe, encourage predatory mites
-
Spray with insecticidal soap, use reflective mulches, encourage beneficial insects like ladybugs and lacewings
-
Hand-pick early morning when sluggish, use traps away from patch, apply neem oil or spinosad during peak activity

Harvest Tips
Tulameen berries ripen sequentially from June through August. Pick when berries are fully red and separate easily from the core without pressure—they should slide off the drupelet cluster. Harvest every 2-3 days during peak season for best flavor and shelf life. Morning picking when berries are cool yields superior quality. Berries are very firm and ship well; they store 7-10 days refrigerated.
Fun Facts
- 🌱 Tulameen was developed at the University of British Columbia's Department of Plant Science and became one of the most commercially successful red raspberry cultivars worldwide, especially valued for premium fresh market sales.
- 🌱 Raspberries are aggregate fruits composed of many drupelets, each containing a seed; when you pick a raspberry, you're collecting 100+ individual fruits bound together on a central core.
- 🌱 Unlike most red raspberries, Tulameen's exceptional firmness and shelf life—up to 10 days refrigerated—makes it unusual in commercial production, where most cultivars deteriorate within 3-5 days.
