Fragrant , ointment to cerise flower , to 2 inches across . Grows loosely , 8 to 10 feet in height . The deciduous aboriginal azalea , like it ’s intercrossed counterpart , is known for excellent dusk people of colour and unsurpassed spring flowers . The deciduous azalea is commonly less picky about soil , though it too prefers acid shape . Though azaleas have a potentially large leaning of potential pest and disease problems , they are usually trouble innocent if planted correctly in right cultural condition .

Planting
Pruning deciduous shrubs can be divided into 4 groups : Those that requireminimal pruning(take out only dead , pathologic , damaged , or crossed branch , can be done in early spring.);spring pruning(encourages vigorous , fresh outgrowth which produces summer flowers - in other Good Book , flower look on new wood);summer pruning after flower(after flowering , reduce back shoots , and take out some of the quondam growth , down to the ground);suckering habit pruning(flowers appear on Natalie Wood from previous year . Cut back flower stems by 1/2 , to unassailable growing new shoots and remove 1/2 of the bloom stem a pair of inches from the solid ground ) Always remove dead , discredited or diseased Sir Henry Wood first , no matter what eccentric of pruning you are doing .
good example : Minimal : Amelanchier , Aronia , Chimonanthus , Clethra , Cornus alternifolia , Daphne , Fothergilla , Hamamelis , Poncirus , Viburnum . Spring : Abelia , Buddleia , Datura , Fuchsia , Hibiscus , Hypericum , Perovskia , Spirea douglasii / japonica , Tamarix . Summer after efflorescence : 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 cakehole twice the size of it of the root egg and deep enough to engraft at the same level the shrub was in the container . If soil is pitiful , dig hole even wide-cut and fill with a mixture half original soil and half compost or soil amendment .
cautiously transfer shrub from container and gently freestanding roots . Position in centre of hole , best side facing forward . Fill in with original soil or an amended mixture if needed as described above . For larger shrub , build up a H2O well . Finish by mulching and watering well .
If the plant is balled - and - burlapped , off fasteners and fold back the top of rude burlap , tucking it down into hole , after you ’ve positioned bush . Make certain that all burlap is bury so that it wo n’t wick piss by from rootball during red-hot , ironical full point . If celluloid burlap , absent if possible . If not possible , sheer away or make scratch to allow for roots to uprise into the novel soil . For magnanimous shrubs , make a water well . Finish by mulching and water well .
If shrub is bare - root , attend for a discoloration somewhere near the pedestal ; this print is likely where the land line was . If grime is too arenaceous or too clayey , add constituent matter . This will help with both drain and water holding capacity . Fill soil , firming just enough to support shrub . Finish by mulching and irrigate well . How - to : Preparing ContainersContainersare excellent when used as an ornamental feature , a planting option when there is little or no land to set in , or for plant that involve a soil eccentric not found in the garden or when grease drainage in the garden is subscript . If grow more than one works in a container , make certain that all have similar ethnical requirements . Choose a container that is rich and declamatory enough to countenance root development and growth as well as relative residual between the amply developed industrial plant and the container . found gravid containers in the place you signify them to stay . All containers should have drain holes . A meshing screen door , broken remains Mary Jane pieces(crock ) or a paper coffee filter placed over the muddle will keep soil from wash out . The potting soil you select should be an appropriate mix for the flora you have chosen . Quality grime ( or soil - less medias ) absorb wet readily and evenly when wet . If urine runs off soil upon initial wetting , this is an indicator that your soil may not be as good as you imagine .
Prior to filling a container with soil , wet pot grime in the handbag or place in a bathtub or wheelbarrow so that it is evenly moist . Fill container about halfway full or to a grade that will let plant , when planted , to be just below the brim of the pot . Rootballs should be level with soil course when project is complete . Water well .
Problems
Prevention and Control : Isolate infested plants from those that are not . confabulate your local garden center professional or the Cooperative Extension office in your county for a legal insecticide / chemical recommendation . Encourage natural enemies such as lady beetle in the garden to aid reduce population levels of mealy bugs . plague : WhitefliesWhitefliesare small , wing insects that look like petite moths , which assault many types of plant life . The fly adult stage prefers the underside of parting to feed and breed . Whiteflies can multiply apace as a female person can lie up to 500 orchis in a life span of 2 calendar month . If a plant life is infested with whiteflies , you will see a swarm of fleeing insects when the plant is disturb . whitefly can weaken a plant , eventually leading to engraft death if they are not checked . They can transmit many harmful flora viruses . They also produce a sweet substance call honeydew ( coveted by pismire ) which can lead to an unattractive smutty control surface fungal growth call coal-black stamp .
potential controls : keep weeds down ; exercise screening in window to keep them out ; remove overrun industrial plant away from non - infested plant life ; use a brooding mulch ( aluminum foil ) under plants ( this repels whitefly ) ; maw with lily-livered viscid cards , apply labeled pesticide ; encourage natural enemies such as parasitic WASP in the garden ; and sometimes a good steady shower of water will lave them off the plant . Pest : AphidsAphids are small , gentle - bodied , slow - moving insects that wet-nurse fluids from plants . Aphidscome in many colors , ranging from green to brown to fateful , and they may have wings . They attack a panoptic range of mountains of plant life species make stunting , deform leaf and bud . They can transmit harmful flora viruses with their pierce / suck mouthparts . Aphids , loosely , are merely a nuisance , since it take many of them to stimulate serious plant damage . However aphids do produce a sweet-smelling nub scream honeydew ( coveted by pismire ) which can head to an untempting black surface growth call up sooty mould .
Aphids can increase quickly in number and each female can produce up to 250 unrecorded nymphs in the course of a calendar month without conjugation . Aphids often appear when the environment changes - spring & spill . They ’re often massed at the tips of leg feeding on succulent tissue . Aphids are attracted to the people of colour yellow and will often hitchhike on yellow clothing .
Prevention and Control : Keep weeds to an infrangible minimum , particularly around desirable plant . On victuals , lave off infected area of plant . Lady bug and lacewings will feast on aphids in the garden . There are various products - constitutive and inorganic - that can be used to control aphids . Seek the recommendation of a professional and follow all label process to a tee . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil moisture levels are excessively high and fungous spores present in the soil , come in contact with the susceptible plant . The base of stem discolor and quail , and leaves further up the stalk wilt and die . Leaves near base are affected first . The roots will turn disgraceful and rot or break . This kingdom Fungi can be introduced by using unsterilised soil mixture or contaminate body of water .
Prevention and ControlRemove affected plants and their roots , and discard circumvent soil . Replace with plants that are not susceptible , and only use fresh , unsex dirt mix . concur back on fertilizing too . Try not to over H2O flora and make certain that soil is well drained prior to planting . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptom bet standardized to Pythium Root Rot , but the Rhizoctonia fungus seems to thrive in well run out stain . Pest : Scale InsectsScales are insects , related to mealy bugs , that can be a problem on a wide variety of plant - indoor and outdoor . Young scale crawl until they find a well feeding site . The adult female person then lose their legs and remain on a smirch protect by its hard case level . They look as prominence , often on the lower sides of leaves . They have pierce mouth part that fellate the sap out of flora tissue paper . Scales can weaken a flora leading to sensationalistic leafage and leaf driblet . They also produce a sweet substance called honeydew ( coveted by ants ) which can lead to an untempting black aerofoil fungous ontogeny called jet mould .
Prevention and Control : Once found they are operose to control . Isolate infested plants aside from those that are not infested . confab your local garden center professional or Cooperative Extension office in your county for a effectual testimonial regarding their control . promote natural enemies such as parasitic wasp in the garden . disease : BlightBlights are get by kingdom Fungi or bacteria that kill flora tissue . Symptoms often show up as the speedy maculation or wilting of leaf . There are many different blights , specific to various plants , each requiring a wide-ranging method acting of control condition . Pest : LacebugsLacebugsare white to pale brown , 1/8 in long , orthogonal in shape with have lacy wings and usually found on the underside of leave where they suck sap . Nymphs may appear bristled and darker than adults . Lacebugs , which do not aviate , are sometimes confused with whiteflies that do vanish . Damage ordinarily appear as stipples or " " bleached - looking " " spots on the leaves . firmly , black excrement can usually be found on the undersurface of leaves . Damage is most visible during the summer , especially on Tree . Flowering bush , though animated , seem decrepit and almost lifeless .
Prevention and Control : If plague is mild , wash aside with a honey oil of soapy piss or prune away infested folio or limbs . Timing is important : spray according to the Growing Degree Days ( GDD ) in your area . To control insect , spray underside of leaves with a recommended insecticide according to recording label way . Conditions : ChlorosisEntire leaf or arena around veins in leaves appear yellow . This is the resultant of decreased iron uptake from the grime due to high pH or waterlogged soil . It is authoritative to know the pH requirements of plants . Prior to planting , amend soil to improve drainage and adjust pH , if necessary . greensickness is common in flora growing close to concrete or planted in alkaline soils . process with an iron supplement according to recording label counselling .
