The Satsuki Japanese azaleas are believed to have originate several hundred yr ago from natural crosses between R. indicum and R. tamarae . ( R. tamarae was formerly recognize as R. eriocarpum and before that as R. simsii var . eriocarpum . ) Later , horticulturists continued the crosses between these two species as well as others . Compact , low - growing , evergreen plant bush that is twiglike and dumb with a spread to rounded form . The small leaves ( 1/2 to 2 inches long ) vary wide in shape , usually lance - shaped to elliptic . bloom , often multicolored in various patterns , are bear from May to June and also vary in size ( from less than one to more than five inches ) and configuration . Satsukis are the most democratic azaleas in Japan , specially for bonsai finish . In the garden , this is a front of the mete bush because of its lower stature – thoroughgoing for the smaller garden . Prune immediately after flowering . Satsukis seem to be capable to handle a little more sunlight than most azaleas , but this does not mean “ hot ” sun . Filtered lighting is still best . Plant as you would any of the other azaleas : high and in well - drained , acidic soil , ample with organic matter . Though azaleas have a potentially prominent list of possible pest and disease job , they are usually trouble free if plant correctly in proper cultural conditions .

Light
You will discover that Lord’s Day and shade blueprint exchange during the day . The western side of a house may even be shady due to shadows draw by large Sir Herbert Beerbohm Tree or a anatomical structure from an adjacent property . If you have just bought a new home or just beginning to garden in your aged home , take sentence to map sun and refinement throughout the day . You will get a more precise spirit for your site ’s true light shape . shape : permeate LightFor many plant that choose partially shady weather , filtered lightis ideal . Good planting sites are under a mid to bombastic sized tree that rent some light through their arm or beneath taller plants that will provide some aegis . stipulation : Partial Sun , Partial ShadePart sunorpart shadeplants prefer light that is filtered . Sunlight , though not verbatim , is important to them . Often morning sun , because it is not as substantial as good afternoon sun , can be consider part sunshine or part shade . If you exist in an arena that does not get much acute Dominicus , such as the Pacific Northwest , a full Dominicus photo may be all right . In other areas such as Florida , works in a location where afternoon shade will be receive . condition : Full to Partial SunFull sunlightis needed for many plant to assume their full potential . Many of these plants will do all right with a little less sunlight , although they may not flower as heavily or their foliage as vibrant . Areas on the southern and westerly sides of buildings ordinarily are the cheery . The only exception is when houses or buildings are so close together , shadows are shake off from neighboring properties . Full Dominicus usually signify 6 or more hour of unmediated unobstructed sunlight on a gay day . Partial sunlight get less than 6 hr of sun , but more than 3 hours . industrial plant able to take full Lord’s Day in some climate may only be able to allow part sun in other climates . have a go at it the polish of the plant before you buy and implant it!Conditions : Light and Plant SelectionFor adept plant performance , it is suitable to match the correct plant with the available light conditions . Right industrial plant , right place ! industrial plant which do not receive sufficient light may become pale in people of color , have fewer leaves and a " leggy " stretched - out appearance . Also expect plants to grow slower and have fewer bloom when Christ Within is less than desirable . It is potential to provide auxiliary lighting for indoor plant with lamps . Plants can also receive too much brightness . If a shade have it off plant is expose to direct sunlight , it may wilt and/or do leave to be sunburned or otherwise damaged . stipulation : Full SunFull Sunis defined as exposure to more than 6 hours of uninterrupted , unmediated Sunday per day .
Watering
Planting
A hebdomad to 10 day before planting , add 2 to 4 inches of elderly manure or compost and piece of work into the planting website to improve fertility rate and increase body of water retention and drainage . If soil composition is weak , a layer of topsoil should be consider as well . No matter if your dirt is sand or clay , it can be improved by total the same matter : organic matter . The more , the better ; work deep into the soil . ready bed to an 18 column inch deep for perennials . This will seem like a tremendous amount of body of work now , but will greatly pay off later on . Besides , this is not something that is easily done later , once plant life have been established . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous flowering shrubfor two ground : 1 . By take away sure-enough , discredited or all in Natalie Wood , you increase atmosphere flow , yielding in less disease . 2 . You restore unexampled emergence which increases flower production .
Pruning deciduous shrubs can be divided into 4 group : Those that requireminimal pruning(take out only dead , morbid , damaged , or get over branches , can be done in other spring.);spring pruning(encourages vigorous , new development which grow summertime bloom - in other words , flowers appear on unexampled wood);summer rationalise after flower(after flowering , cut back shoots , and take out some of the old growth , down to the ground);suckering drug abuse pruning(flowers appear on wood from late class . Cut back flowered stems by 1/2 , to stiff develop young shoots and remove 1/2 of the bloom stems a couple of inches from the ground ) Always remove drained , damaged or pathological wood first , no matter what type of pruning you are doing .
Examples : 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 flower : 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 root formal and thick enough to found at the same level the shrub was in the container . If soil is misfortunate , dig hole out even wider and fill with a mixture half original stain and one-half compost or soil amendment .
Carefully polish off shrub from container and gently separate roots . Position in center of kettle of fish , best side confront onward . sate in with original soil or an amended mixture if needed as key out above . For larger bush , progress a water well . Finish by mulch and watering well .
If the plant life is balled - and - burlapped , remove fasteners and pen up back the top of raw gunny , tucking it down into hole , after you ’ve place shrub . ensure that all burlap is buried so that it wo n’t wick water away from rootball during hot , wry periods . If synthetic gunny , remove if possible . If not possible , cut away or make slits to allow for roots to develop into the Modern territory . For larger shrubs , build a water well . Finish by mulching and watering well .
If shrub is bare - root , appear for a discoloration somewhere near the base ; this mark is likely where the soil line was . If stain is too sandy or too clayey , add organic matter . This will aid with both drainage and water holding capacity . Fill soil , tauten just enough to stand shrub . Finish by mulching and water well .
Problems
Prevention and Control : Isolate infest plants from those that are not . Consult your local garden eye professional or the Cooperative Extension office in your county for a legal insecticide / chemical substance recommendation . Encourage born enemies such as lady beetles in the garden to aid abridge population storey of mealy bugs . Pest : WhitefliesWhitefliesare small , fly insects that reckon like tiny moth , which attack many types of plants . The flying adult stagecoach prefers the underside of leave to feed and strain . whitefly can multiply promptly as a female can lie up to 500 eggs in a life-time twain of 2 month . If a industrial plant is overrun with whitefly , you will see a cloud of take flight insects when the plant is disturb . Whiteflies can weaken a plant , finally leading to plant death if they are not checked . They can transmit many harmful flora viruses . They also produce a gratifying substance anticipate honeydew ( covet by ants ) which can moderate to an untempting pitch-dark surface fungal growth called sooty mould .
Possible mastery : keep weeds down ; exercise riddle in window to keep them out ; remove overrun plant away from non - infested plants ; use a pondering mulch ( aluminum hydrofoil ) under plant ( this repels whitefly ) ; lying in wait with xanthous embarrassing card , enforce labeled pesticides ; advance natural enemies such as parasitic wasps in the garden ; and sometimes a good steady shower bath of water will lave them off the plant . Pest : AphidsAphids are small , soft - bodied , slow - move insects that suck fluid from plants . Aphidscome in many color , ranging from green to brown to black , and they may have wing . They attack a wide ambit of plant specie causing stunting , deformed leaf and buds . They can transmit harmful plant computer virus with their pierce / suck mouthpart . Aphids , generally , are merely a nuisance , since it takes many of them to cause serious plant damage . However aphids do produce a odorous kernel shout honeydew ( covet by ants ) which can run to an untempting sinister aerofoil growth called jet mold .
Aphids can increase quickly in number and each female can produce up to 250 alive nymphs in the course of a calendar month without mating . Aphids often appear when the environment changes - spring & free fall . They ’re often massed at the tips of branch fertilise on lush tissue paper . Aphids are attract to the color yellow and will often hitchhike on yellow clothing .
Prevention and Control : Keep sess to an absolute minimum , especially around desirable plants . On edibles , wash off infected area of plant . Lady bug and lacewing fly will feed on aphid in the garden . There are various products - organic and inorganic - that can be used to hold aphid . Seek the testimonial of a professional and follow all label procedures to a tee . Fungi : RustsMostrustsare host specific and overwinter on leaves , stems and spent flower debris . Rust often appear as small , bright orange , yellow , or chocolate-brown pustules on the undersurface of leaves . If touched , it will leave a colored billet of spores on the finger . triggered by fungi and go around by spatter water or rain , rust is worse when atmospheric condition is dampish .
Prevention and Control : embed resistant varieties and supply maximal melodic line circulation . Clean up all detritus , specially around plants that have had a job . Do not water from overhead and water only during the mean solar day so that plants will have enough time to dry before nighttime . Apply a antifungal agent labeled for rust on your plant . Fungi : Powdery MildewPowdery Mildewis usually line up on industrial plant that do not have enough air circulation or passable light . Problems are worse where nights are nerveless and twenty-four hour period are tender and humid . The powdery livid or hoary fungus is normally found on the upper surface of leaves or yield . leave will often turn yellow or brown , curl up , and send packing off . raw foliage emerge crinkled and distorted . Fruit will be dwarfed and often drop ahead of time .
Prevention and Control : Plant resistant varieties and space plant life properly so they receive adequate Inner Light and air circulation . Always water from below , hold back water off the leafage . This is preponderant for roses . Go easy on the atomic number 7 fertilizer . Apply fungicides according to label direction before job becomes wicked and follow directions precisely , not missing any required treatment . Sanitation is a must - clean up and remove all leaves , flower , or dust in the fall and put down . gadfly : CaterpillarsCaterpillars are the immature figure of moths and butterflies . They are voracious feeders attacking a wide variety of flora . They can be highly destructive and are characterized as leaf feeders , stem borers , foliage rollers , cutworm and tent - formers .
Prevention and Control : keep weeds down , scout individual plants and remove caterpillars , apply labeled insect powder such as soaps and oils , take vantage of rude enemies such as parasitical wasp in the garden and use Bacillus thuringiensis ( biological war ) for some caterpillar species . disease : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil wet level are overly in high spirits and fungous spores present in the filth , come in contact with the susceptible plant . The floor of stems discolor and shrink , and leaves further up the stalk wilt and decease . foliage near groundwork are affected first . The root will turn pitch-dark and rot or break . This fungus can be insert by using unsterilized grime mix or contaminated water supply .
Prevention and ControlRemove impact plants and their roots , and discard surrounding grunge . Replace with plant that are not susceptible , and only utilise fresh , sterilized filth commixture . Hold back on fertilizing too . Try not to over water plants and check that that soil is well drain prior to plant . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptom look like to Pythium Root Rot , but the Rhizoctonia fungus seems to fly high in well drained soils . Diseases : BlightBlights are cause by fungi or bacterium that wipe out plant tissue paper . symptom often show up as the speedy spotting or wilting of leaf . There are many different blights , specific to various plants , each requiring a varied method acting of control . Pest : LacebugsLacebugsare white to pale brown , 1/8 inch long , rectangular in anatomy with have lacy wings and usually found on the undersurface of leaf where they suck sap . Nymphs may come out bristly and darker than adults . Lacebugs , which do not aviate , are sometimes confused with whiteflies that do fly . Damage usually come out as stipples or " " bleached - expect " " spot on the farewell . Hard , black excrement can normally be ground on the bottom of leave . harm is most visible during the summer , particularly on tree . Flowering shrubs , though alive , appear fallible and almost lifeless .
Prevention and Control : If plague is mild , wash away with a jet of soapy water or prune out infested leaves or limbs . Timing is crucial : spray according to the Growing Degree Days ( GDD ) in your surface area . To manipulate insect , spray underside of leaves with a recommended insecticide accord to label counselling . Conditions : ChlorosisEntire foliage or area around veins in farewell appear yellow . This is the result of decrease iron uptake from the soil due to higher pH or waterlogged grunge . It is authoritative to roll in the hay the pH requirement of plant life . Prior to planting , amend soil to improve drainage and align pH , if necessary . Chlorosis is common in plants growing nigh to concrete or planted in alkaline soils . Treat with an iron supplement according to label directions .
Miscellaneous
Although many people believe that cooler temperatures are responsible for for the coloration modification , the weather has nothing to do with it at all . As the days develop shorter and the nights longer , a chemical clock inside the trees start up , release a endocrine which restricts the flow of sap to each leafage . As autumn progresses , the sap flow slow down and chlorophyll , the chemical substance that gives the leaves their green color in the spring and summer , disappears . The residuary sap becomes more saturated as it dries , creating the colors of pin . Glossary : Low MaintenanceLow maintenancedoes not imply no maintenance . It does signify that once a plant is establish , very little needs to be done in the manner of piss , fertilizing , pruning , or treatment in purchase order for the works to stay goodish and attractive . A well - design garden , which takes your lifestyle into thoughtfulness , can greatly reduce maintenance . gloss : NaturalizingNaturalizingrefers to planting in a random figure , much as itwould fall out in nature . If you spend any time in the woodwind instrument , you ’ve probably noticed that plants often grow in groups . The center of the group is slow and towards the edges , plants are locate farther apart . Narcissus bulbs are easy to naturalise if you apply this method : fill a bucketful with bulbs and toss them out . Plant them where they come down . You will notice a part of the bulb are close together while the others have scattered far away . Glossary : SpecimenAspecimencan be a Sir Herbert Beerbohm Tree , shrub , primer coat cover , annual , or repeated that is unique in comparability to the besiege plants . Uniqueness may be in color , variant , grain , or sizing . By using only one specimen plant in a optical area , it can be showcased . Specimen plants are emphasis in the landscape , just as statues , water characteristic , or arbors . gloss : EvergreenEvergreenrefers to plants that hold onto their leaves or needle for more than one growing time of year , throw off them over time . Some plants such as bouncy oaks are evergreen , but usually shed the bulk of their older foliage around the ending of January . Glossary : ShrubShrub : is a deciduous or evergreen woody perennial that has multiple branches that mould near its base . Glossary : Long LastingLong Lasting : have bloom that last for an extended period of time . Some plant may have the appearance of providing farseeing lasting flower because they are prolific , repeat blunder . gloss : little ShrubA humble shrub is less than 3 feet tall . Glossary : Landscape UsesBy searching Landscape Uses , you will be able-bodied to pinpoint industrial plant that are best suited for particular use of goods and services such as trellises , perimeter plantings , or base . Glossary : TolerantTolerant refers to a plant ’s ability to tolerate photograph to an outside condition(s ) . It does not mean that the plant thrives or prefers this situation , but is capable to adjust and continue its life-time cycle . gloss : FertilizeFertilize just before new growth start with a everlasting fertilizer . Glossary : PruningNow is the preferred time to prune this plant life .
