Canes are slightly topped and then are trained and tied to adjacent plant or tying wire. This is done in late winter to minimize risk of cold injury
Arc Cane system
Primocanes just prior to trainingSummer-bearing red raspberry
Primocanes topped and bundle trained
Bundle (topped) system
Top canes to about 6 ft
Fruiting laterals on floricanes
Floricane developmentnext spring
Typical trellis system has 1 or 2 top wire(s) and 2 lower wires (in some cases moveable) but there are many variations
Trellis – floricane-fruiting raspberry
• Two moveable lower wires
Trellis – floricane-fruiting cultivars
Dr. Bernadine Strik, Oregon State University 12
• Trellis should have a “T” piece of some kind to hold up primocanes and short floricanes if double cropping
Maintain hedgerow to 1 to 1.5 ft wide using tillage or hoeing
Trellis – primocane-fruiting cultivars Primocane-fruiting raspberry
A. Single crop (only produce fruit on primocane)
B. Double crop (early crop on floricane; later crop on primocane)
Primocane-fruiting raspberries
Single cropBefore pruning
Single crop• Prune by cutting
off primocanes in late winter
• Use pruners or weed wacker with blade
After pruning in late winter
Primocane-fruiting raspberry
• Primocanes start to grow repeating production cycle by fruiting in late summer through autumn
Early spring
Single crop
Primocane-fruiting raspberry
Double crop
Late summer
• Primocanes fruit and a portion of this cane is left to produce a floricanecrop

• Tip portion flowers and fruits• Fruiting stops when gets too cold in autumn
First year
Second yearShould have been pruned in late winter
Floricane
Double cropPrimocane-fruiting raspberry
February
Double crop
• In late winter, prune off top portion of the canes that fruited in autumn (these are dead)
Primocane-fruiting raspberry
SpringFloricane crop in early summer
Raspberries in containers• Primocane-fruiting is best• Choose a well-drained potting soil
mix• One plant per 12 to 25 gallon
container (drain holes in bottom)• Plant (2 ft apart) in good soil in
raised bed that is 2 ft deep. Need good drainage (below bed also)
• Double crop• Remove dead floricanes after fruiting• Remove dead primocane tips in winter• Thin primocanes to best 3 in the pot in early summer
Floricane crop, June 27
Primocanes will fruit in late summer - fall
Black Raspberries Jewel(only cultivar recommended for good
Black raspberry• In winter• Floricanes are dead• Remove these by
pruning at the base• Shorten primocane
branches
Pruning and Training Raspberries Module
• 1.25 hours of video in 4 mini lectures • Module includes:
• types of raspberries grown and regional adaptation• the basics of plant growth and understanding the differences between
raspberry types• how to prune and train floricane-fruiting red raspberries• how to prune and train floricane-fruiting black raspberries• how to prune and train primocane-fruiting raspberries.
• Beautiful ornamental (big double flowers)• Good flavor• Small seeds, great for jam and freezing• Fruiting season: Early
Floricane-fruiting
Trailing blackberry
Dr. Bernadine Strik, Oregon State University 18
During harvest (generally July)Trailing blackberry
• Floricanessenesce (die) after harvest
• Prune out the dead canes
• Cut them to near the crown
• Do not cut or damage the primocanes
Pruning and training
Prune off floricane bundle near crown
Trailing BlackberriesTraining primocanes
Divide primocanes into two bundles
Train half one way on trellis and the other in the opposite direction
Trailing BlackberriesTraining primocanes
Loop bundles around the two upper training wires

Dr. Bernadine Strik, Oregon State University 19
Bring plants inside if frost is forecast during bloom or fruiting
Primocane-fruiting blackberry Fruiting on primocane branches Primocane-fruiting blackberry
• Fruiting on floricanes• Tip new primocanes to 3 ft
In winter prune primocanes(remove parts that fruited last fall)
After pruning
Pruning and Training Blackberries Module
• 1.75 hours of video in 6 mini lectures• Module includes:
• types of blackberries grown and regional adaptation• the basics of plant growth and understanding the differences between types• how to prune and train floricane-fruiting trailing blackberries• how to prune & train floricane-fruiting semi-erect and erect blackberries• how to prune & train primocane-fruiting blackberries for single or double crop
Symptoms of soil pH being too high“lime induced iron deficiency”
Before Planting:
• Test soil – 6 months prior to planting (previous fall typically) Test for soil pH and nutrient levels
• In the fall, incorporate elemental S to achieve target pH of about 5.5 prior to planting
• In spring, incorporate Douglas fir bark mulch or sawdust (~ 4 inches deep tilled in). Do NOT use animal-based or plant-based composts which have a very high pH (7 to 8)
• Form or build raised beds, if possible
Growing in containers• Works well• Good option if soil cannot
be made to suit blueberry• Choose a potting mix that is
about 50% fine bark, 40% peat moss, and 10% perlite. Make sure no lime has been added
• One plant per 12 to 25 gallon container (drain holes in bottom)
• Or plant in similar made “potting mix” in raised bed that is 2 ft deep (plant 3 to 4 ft apart). Need good drainage (below bed also)
