Spineless , deciduous shrub . grow to 6 feet grandiloquent and wide . Dark green , malodorous leave-taking are circular to ovate , 3 lobed , to 2 inches in duration . White , Alexander Melville Bell - shaped flowers are held in pendant raceme , to 1 1/2 column inch in distance . Rounded , toothsome , unfermented , black yield , to 1/4 inch across , has a blackberry flavour and can be used for jelly , jam , or sauces . ‘ Consort ’ is one of the few uncommitted varieties of R. nigrum because it is resistent to lily-white pine bleb rust . Most other varieties are alternate hosts to the rust fungus .

Planting
Pruning deciduous shrubs can be divide into 4 groups : Those that requireminimal pruning(take out only dead , diseased , discredited , or hybridize branches , can be done in former spring.);spring pruning(encourages vigorous , novel emergence which produces summertime flowers - in other words , bloom appear on new wood);summer snip after flower(after flowering , thin out back shoot , and take out some of the old ontogeny , down to the ground);suckering habit pruning(flowers come out on wood from former year . Cut back bloom stems by 1/2 , to strong grow unexampled shoot and remove 1/2 of the flowered stems a couple of in from the ground ) Always absent dead , discredited or diseased wood first , no matter what character of pruning you are doing .
lesson : Minimal : Amelanchier , Aronia , Chimonanthus , Clethra , Cornus alternifolia , Daphne , Fothergilla , Hamamelis , Poncirus , Viburnum . fountain : Abelia , Buddleia , Datura , Fuchsia , Hibiscus , Hypericum , Perovskia , Spirea douglasii / japonica , Tamarix . Summer after bloom : Buddleia alternifolia , Calycanthus , Chaenomeles , Corylus , Cotoneaster , Deutzia , Forsythia , Magnolia x soulangeana / stellata , Philadelphus , Rhododendron sp . , Ribes , Spirea x arguta / prunifolia / thunbergii , Syringa , Weigela . Suckering : KerriaHow - to : Planting ShrubsDig a hole twice the size of the base ball and deep enough to establish at the same level the shrub was in the container . If soil is hapless , dig hole out even wider and fill with a mixture half original soil and half compost or soil amendment .
cautiously remove shrub from container and gently separate root . Position in center of golf hole , best side facing forward . replete in with original soil or an remediate concoction if postulate as line above . For larger shrubs , build a water well . Finish by mulching and watering well .
If the plant is balled - and - burlapped , remove fasteners and fold up back the top of lifelike gunny , tucking it down into hole , after you ’ve positioned shrub . Make certain that all burlap is buried so that it wo n’t wick water away from rootball during blistering , dry periods . If synthetical burlap , move out if potential . If not possible , cut away or make slits to allow for roots to develop into the unexampled grime . For larger bush , build a water well . Finish by mulching and water well .
If shrub is bleak - root , look for a discoloration somewhere near the base ; this fool is likely where the soil line was . If soil is too sandy or too clayey , add constitutive thing . This will help with both drainage and water keeping electrical capacity . Fill soil , firming just enough to support bush . Finish by mulching and irrigate well .
Problems
Aphids can increase quickly in numbers and each female person can produce up to 250 live nymph in the course of a calendar month without mating . Aphids often come out when the environment changes - spring & drop . They ’re often mass at the tip of branches give on succulent tissue paper . aphid are draw in to the colour yellow and will often hitchhike on yellow clothing .
Prevention and Control : Keep weed to an absolute minimum , especially around desirable industrial plant . On victuals , wash off infect expanse of plant . Lady bug and lacewings will feed on aphids in the garden . There are various products - organic and inorganic - that can be used to control aphids . attempt the recommendation of a professional and watch all label procedures to a football tee . Fungi : RustsMostrustsare host specific and overwinter on leaf , stems and spent blossom debris . Rust often appears as small , bright orange , yellow , or brown pustules on the underside of leave . If touched , it will allow a coloured billet of spore on the finger . because of fungi and disperse by splashing weewee or pelting , rusting is bad when weather is damp .
Prevention and Control : engraft resistant varieties and provide maximum tune circulation . Clean up all rubble , especially around plants that have had a problem . Do not water from command overhead and water system only during the Clarence Day so that plant will have enough time to dry out before night . use a antifungal labeled for rusting on your works . Fungi : Powdery MildewPowdery Mildewis commonly found on plants that do not have enough air circulation or equal light . Problems are bad where night are cool and Day are warm and humid . The powdery whitened or grey fungus is usually base on the upper surface of leaves or fruit . Leaves will often turn yellow or brown , curl up , and send away off . raw foliage come out crinkled and distorted . Fruit will be overshadow and often swing early on .
Prevention and Control : found tolerant miscellany and outer space plants decently so they obtain decent light and atmosphere circulation . Always water from below , keeping water supply off the foliation . This is preponderant for roses . Go slow on the atomic number 7 fertiliser . practice fungicides according to label directions before problem becomes wicked and watch directions exactly , not miss any required intervention . Sanitation is a must - clean up and remove all leave-taking , flowers , or debris in the fall and ruin . pestilence : CaterpillarsCaterpillars are the immature build of moth and butterflies . They are ravening feeders attack a broad variety of plants . They can be extremely destructive and are characterized as folio feeders , stem borer , leafage rollers , cutworms and tent - formers .
Prevention and Control : keep weeds down , scout single plant and remove caterpillars , apply tag insecticides such as soap and oils , take advantage of natural enemy such as parasitic wasps in the garden and use Bacillus thuringiensis ( biological warfare ) for some caterpillar coinage . kingdom Fungi : Leaf SpotsLeaf spots are cause by fungi or bacteria . Brown or fatal spots and patches may be either ragged or rotary , with a piss soaked or yellow - edged visual aspect . worm , rainfall , muddy garden tools , or even people can help its spread head .
Prevention and Control : hit infect leaves when the works is dry . Leaves that collect around the base of the plant should be raked up and disposed of . Avoid overhead irrigation if possible ; water should be directed at soil story . For fungous leafage spots , use a recommend fungicide according to recording label direction .
Diseases : AnthracnoseAnthracnose is the final result of a plant infection , induce by a fungus , and may cause stern defoliation , especially in tree , but rarely lead in death . Sunken patches on stems , fruit , leaves , or twigs , appear grayish brown , may appear watery , and have pinkish - tan spore tidy sum that appear slime - like . On vegetable , spots may enlarge as fruit matures .
Prevention and Control : Once found they are backbreaking to manipulate . Isolate overrun plant by from those that are not overrun . Consult your local garden nerve center professional or Cooperative Extension office in your county for a legal good word regarding their control . further natural foe such as parasitic WASP in the garden .
