Intro to Raspberry Production and Uncommon Small Fruits Grant McCarty University of Illinois Extension Local Foods and Small Farms Educator Basics of Raspberry Production • Short-shelf life • Field or high tunnel production • A good U Pick option • Most are thorned • ‘Joan J’ an exception • Pruning will be an absolute must • Trellis needs in most cases • Most common= Red Type • But Yellow, Purple, and Black show increasing interest Basic Plant Structure •Canes live for two years • 1st Year: Primocanes • No fruit from them except if it’s an everbearing type. • Develop fruit buds in the fall • 2nd Year: Floricanes • Buds go dormant into 2nd year • Need 800 chilling hours (25-40 F) • Produce fruit and then die. • Floricanes pruned out Distinguishing primocanes from floricanes Raspberry Types •Red Raspberries • Red, Summer bearing (2-3 ft, 6- 10 ft btwn rows): • ‘Boyne’- very hardy, good for freezing • ‘Killarney’-good for fresh market • ‘Lauren’- good quality, large fruit • ‘Titan’- large, mild flavor • ‘Octavia’, ‘Encore’, ‘Tulamagic’, ‘Liberty’ Raspberry Types • Red, Everbearing (2-3ft, 6-10 ft) • Aka fall bearing/primocane fruiting • Mow off canes in late winter • Do not have to hand remove flouricane • Less disease pressure • Varieties • ‘Joan J’- early, spineless canes • ‘Jaclyn’- early, dark red • ‘Heritage’- good yields, hard to pick • ‘Anne’, ‘Nova’- good fruit size • ‘Josephine’- late season • ‘Autumn Bliss’, ‘Autumn Britten’ Raspberry Types •Non-Red • Yellow (2-3 ft, 6-10 ft between) • Red raspberry without red pigment • Will have everbearing and summer bearing types • ‘Goldie’ • ‘Amber’ • ‘Fall Gold’- good marketability • ‘Anne’- heat tolerant • ‘Honeyqueen’ (everbearing)-peach colored berries Raspberry Types •Black (4ft, 8-10 ft) • Not as winter hardy as red • Tend to be a bit more compact • Disease susceptible and less productive? • Varieties • ‘Bristol’- medium-large, firm fruit, high yield potential • ‘Jewel’- earlier ripening, anthracnose resistance, very hardy • ‘Blackhawk’- lg berries, vigorous • ‘Allen’- vigorous, moderate yields Raspberry Types • Purple (3-5ft, 10-12 ft) • Cross between red and black raspberries • Tend to be a bit more compact • Moderate hardiness • Fruit is larger and juicer than black • Varieties • ‘Brandywine’-large and tart fruit • ‘Royalty’-large and sweet fruit, not recommended for U Pick (based on growth) • ‘Estate’-flavor between Brandywine and Royalty Establishment • Full sun, well-drained soil, good air flow (but not too windy) • pH between 6.0-6.5 • Avoid planting in area with previous Verticillium susceptible crops • Pre-plant cover crop of Rye for weed control • Mix in compost before planting • Place the crown 1-2 inches above soil surface • Red/Yellow Raspberries: allow to spread to 12 inches • Purple/Black: will “hill” into a cluster Planting Systems • Hill system - Plants grown in hills, wide spacing, weed control by cultivation between and within row, recommended for gently sloping areas. Good for black and purple types of raspberries. • Hedgerow system - Plants are grown in continuous rows about one to two feet wide to form a hedge. Control by cultivation confined to one direction. More space saving, good for cultivars that produce a lot of suckers. Good for red and yellow raspberries. • Linear system - A modification of the two above, no suckers are allowed to grow by cultivating the width around the parent plant. Good for black and purple raspberries. High Tunnel Raspberries • Fertility should be lower on N • May need to consider a double-plastic layer • Keep up with moisture in bed- double drip • Issues: Spider Mites, Powdery Mildew • Results from Dixon Springs: • ‘Joan J’- best performing, thornless, good flavor • ‘Autumn Britten’- 2nd best, fruit size easy to harvest • ‘Nanthahala’- poor performer, maybe colder climate Mulching • Landscape fabric (Planting) • Expect several years of use • Can restrict primocanes emergence from roots • Plastic (Planting) • Needs irrigation • Usually breaks down within one season • Can restrict primocanes emergence from roots • Organic Mulches • Annual replacement • Labor intensive? Established Needs • Established Plants • Apply 2-4 ounces of ammonium nitrate per original plant every spring or alternatively use equivalent lower rates of 10-10-10 compound fertilizers. • Ensure higher fertilizer rates in sandy soils and with older plants. • Keep the area between rows weed free. This can also be achieved by seeding perennial grass or a mixture of grass and a legume as a cover crop. • When controlling weeds around the plants, do not dig 2-3 inches deep to avoid root injury. • Use trellis support to protect plants from wind injury. Raspberry Fruiting • For U Pick and longer season, look to have mix of early and late maturity • Reds/Yellows • Terminal buds bloom 1st and progress on laterals and on down to lower laterals • Fruit ripens over an extended period of time • Blacks and Purple • Fruit ripens over a short period of time • 2 to 2.5 weeks of production Bramble Diseases • Some varieties have disease resistance • Good airflow, pruning, trellising, and spacing can help prevent disease • Cane Blight • Start in wound sites of the primocanes. • Spreads through the cane from the wound and causes cankers to form. • Cankers caused by the cane blight fungus start out as reddish- brown streaks under the bark. • If the infection girdles the stem, the entire cane may wilt and die. Raspberry/Blackberry Cane Blight Raspberry Spur Blight Bramble Diseases • Anthracnose • Little round, sunken pits in the bark of the cane. • Spots are white to pale tan, while the margins sometimes are a purplish red. • Smaller spots than other blights • Very common on black raspberries but it can also occur on susceptible red raspberry varieties. Uncommon Small Fruits • Potentially expand your market • Reach new customers • Potentially diversify your operation • Suggestion: Test plot and talk to others • Major drawback: Not as much research as others • Variety and pest unknowns • Climate issues • General growth characteristics Grower Challenges • Who is your buyer going to be? • Grower Groups?

    CMG GardenNotes #762 Growing Blackberries in Colorado Gardens Outline: Types and cultivars, page 1 Planting and care of blackberries, page 2 Trellising and pruning, page 2 Trailing blackberries, page 2 Erect blackberries, page 3 Primocane-fruiting erect blackberries, page 3 Semi-erect blackberries, page 3 In blackberries, the receptacle (white core of the fruit) is part of the fruit when picked. In raspberries the receptacle remains on the plant when picked. Types and Cultivars Trailing blackberries produce vigorous primocanes (first-year vegetative cane) from the crown of the plant rather than roots. Second year floricanes produce long shaped fruit with relatively small seeds and a highly aromatic, intense flavor. They are not hardy in climates like Colorado, experiencing damage at temperatures of 13ºF in mid winter, and in the 20sºF in late winter/early spring. Erect blackberries have stiff arching canes that are somewhat self-supporting. However, they are much easier to handle when trellised and pruned. Summer prune or tip primocanes to encourage branching and increase fruit production on the second-year floricanes. Plants can become invasive to an area as they can produce new primocanes (suckers) from roots. Erect blackberries produce fruit with relatively large seeds. Flavor and aroma are not as intense as in the trailing blackberry cultivars. They are semi-hardy in climates with rapid springtime temperature shifts, like Colorado. Primocane-fruiting cultivars of erect blackberries produce fruit on the new canes. This make management easier as the canes can be cut to the ground each winter. Suggested cultivars include Prime Jan and Prime Jim. Semi-erect blackberry plants are thornless and produce vigorous, thick, erect canes from the crown.

They are either deciduous or evergreen shrubs or climbers. They are found in a range of different habitats all over the world and can be found growing in places including mountain slopes, woodlands and coastal sand dunes. Rubus species vary from frost to fully hardy and like to be grown in moderately fertile, well-drained soil. The plants produced saucer or cup-shaped flowers (generally white or pink) followed by edible fruit. Some entries had stems bearing thorns whilst others were thornless. Trial objectives To select suitable cultivars which are worthy of the Award of Garden Merit (AGM) and suitable for the amateur to grow in a garden. Also to demonstrate the cultivation of blackberries and hybrid berries. Evaluation The Fruit Trials Forum assessed entries in the trial for the Award of Garden Merit on the following dates: 2013: 17 July, 7 August, 28 August, 2 October. 2014: 25 June, 16 July, 13 August, 1 October. 2015: 15 July, 19 August, 30 September.

    J&L’s Gardening Handouts Tips and Suggestions for Year Round Gardening www.JLGardenCenter.com www.JLLandscapingUtah.com [email protected] 2016 Raspberries & Blackberries Red raspberries, yellow raspberries, blackcap raspberries, and blackberries are all very closely related and belong to the rose family. Botanists separate the raspberries from the blackberries by determining if the core stays in the ripe fruit, or if the core is lost during picking. Berries with the core intact are blackberries and berries that lose their core are raspberries. A few berries are a cross between blackberries and raspberries, such as Loganberry and Tayberry. Blackberries aren't as popular as Raspberries, but they are just as delicious. Although blackberries and raspberries are closely related they are quite different in their growth habits. Blackberries generally grow long, trailing canes and spread when the tips of their canes grow roots when they come in contact with the soil. Red and yellow raspberries generally grow upright canes and spread from underground roots. Blackcap raspberries grow upright, arching canes and grow in clumps. They spread when their arching canes touch the ground and produce new roots. Primocane: First Year Shoots. These are the green shoots that problem, especially in plants grown in clay soils.

    Blackberries 2021

    Blackberries Blackberries are a hardy, no-fuss berry crop that provides baskets full of tasty, nutrient rich fruit with little effort. The Himalayan (“wild”) blackberry grows like weeds next to roads and along trails here in the PNW, a testament to blackberry’s vigorous nature and suitability for our climate. Varieties carried by Sky are less invasive but equally hardy and delicious. Honestly, what more can you want in a berry? CARE INSTRUCTIONS All of the blackberry varieties that Sky carries are cold hardy to at least -5°F; some are even hardier. Blackberries will grow vigorously in almost any type of soil, often with little or no fertilizer. If production seems to have decreased, you can apply a flower or vegetable fertilizer around bloom time. A steady moisture supply is necessary, especially in sandy soils that don’t retain moisture. Keep your blackberry planting clean to eliminate weed competition and sucker growth. However, avoid cultivating deeply around thornless varieties; if the feeder roots are damaged, they will send up thorny suckers that will need to be pruned out. BLACKBERRY GROWTH 101 The crowns of blackberry plants are perennial: new canes arise from them every year. The canes themselves are usually biennial; each one lives for two years. During the first year, they grow and send out laterals (side branches). The second year, small branches grow from buds on the one-year-old canes. Fruit is borne on these side branches. After fruiting, the entire cane dies, and new canes sprout next year from the root. TRAILING & SEMI-TRAILING VARIETIES Trailing varieties should be planted 8 to 12’ apart.

    Blueberries Raspberries Strawberries Blackberries Kiwi Currants and Gooseberries Miscellaneous Small Fruits Click on any fruit to return to the top BLUEBERRIES Highbush blueberries, Vaccinium corymbosum, are both ideal fruit producing and ornamental specimen plants for Pacific Northwest gardens, especially those west of the Cascades. Commercial interest in blueberries has increased as more and more consumers have been introduced to the fruit's tangy flavor in yogurt, ice cream, preserves, and fresh pack. Plants can grow to a height and circumference of 5 to 6 feet. During the spring blooming period of late April to early May, plants usually produce abundant white to pinkish urn-shaped flower clusters, followed by a bountiful crop of tasty berries from early July through mid-September, depending on the cultivar. In autumn, some cultivars display striking yellow-to-scarlet foliage before the leaves fall. As members of the plant family Ericaceae, blueberries share the same soil and climatic preferences as rhododendrons and azaleas. The plants thrive in areas of moderate summer temperatures and acidic soils. Cold hardiness is not a major factor. The plants can survive midwinter temperatures as low as -20°F and -25°F. An open site with air drainage reduces spring frost injury to flower blossoms. While blueberries survive the warmer summers of eastern Washington, yields there rarely match those from west of the Cascades. A growing season of at least 140 days produces the best fruit. Young plants generally do not begin to bear fruit until they are between 4 and 5 years old. Once a bush is established, life expectancy can be unlimited.
