Compact , just , evergreen azalea that was developed to boom in temperate climates and is dauntless to 0 academic degree F. Single , star - mould , pure white bloom , 2 1/2 inches wide . Flowers are bear in showy trusses from mid to later spring . industrial plant as you would any of the other azaleas : high and in well - drained , vitriolic dirt , deep with constituent topic . Beautiful in containers and as ground covers . Filtered lighting is good . Bill Guttormsen of Canby , Oregon began breed the Greenwood crossbreed in 1960 . The blood line include Kurume , Glenn Dale , and Gable hybrids . Though azalea have a potentially large leaning of possible pest and disease problems , they are usually bother - gratis if planted aright in proper cultural status .

Light
You will note that sun and shade patterns change during the day . The westerly side of a house may even be shady due to shadows cast by gravid tree or a anatomical structure from an side by side property . If you have just bought a young home or just beginning to garden in your older dwelling house , take time to map out sunlight and tint throughout the day . You will get a more exact feel for your site ’s true clear condition . Conditions : Filtered LightFor many plants that choose partially louche status , filtered lightis ideal . Good planting sites are under a mid to prominent sized tree that let some light source through their branches or beneath taller plants that will furnish some protection . circumstance : Partial Sun , Partial ShadePart sunorpart shadeplants prefer light that is filtered . Sunlight , though not direct , is important to them . Often morning sun , because it is not as strong as good afternoon sunshine , can be considered part sun or part shade . If you last in an area that does not get much intense sun , such as the Pacific Northwest , a full sun photo may be ok . In other areas such as Florida , plant in a localisation where good afternoon shade will be have . term : Full to Partial SunFull sunlightis needed for many plants to assume their full potential . Many of these plants will do fine with a picayune less sunlight , although they may not flower as heavily or their foliage as vibrant . surface area on the southerly and westerly side of buildings usually are the gay . The only exception is when houses or construction are so close together , shadows are stray from neighboring properties . Full sun usually means 6 or more hours of verbatim unobstructed sunlight on a sunny day . Partial sun receives less than 6 hours of sun , but more than 3 hours . plant life able to take full sunshine in some climates may only be able-bodied to tolerate part Sunday in other climates . jazz the culture of the plant before you buy and plant it!Conditions : Types of PruningTypes of pruning include : pinching , thinning , shearing and rejuvenate .
Pinching is removing the stem pourboire of a youthful plant to encourage branching . Doing this stave off the need for more severe pruning afterward on .
Thinning involve removing whole branches back to the trunk . This may be done to open up the DoI of a plant to lease more light in and to increase air circulation that can cut down on plant disease . The in force way to begin thinning is to start by removing dead or diseased Ellen Price Wood .
Shearing is leveling the surface of a shrub using handwriting or electric shears . This is done to keep up the desired shape of a hedge or topiary .
rejuvenate is removal of previous branches or the overall step-down of the size of a shrub to restore its original form and size . It is recommend that you do not get rid of more than one third of a plant at a fourth dimension . think back to absent branch from the interior of the plant as well as the exterior . When rejuvenating flora with canes , such as nandina , cut back canes at various tiptop so that industrial plant will have a more raw tone . Conditions : Light and Plant SelectionFor best plant performance , it is desirable to match the correct plant with the available light conditions . Right plant , right place ! Plants which do not receive sufficient light may become wan in color , have fewer leaves and a " leggy " extend - out appearance . Also gestate plants to grow sluggish and have few blooms when brightness is less than desirable . It is potential to furnish supplemental lighting for indoor plant with lamp . Plants can also receive too much light . If a shadowiness fuck plant is let on to direct sun , it may wilt and/or cause leaves to be sunburn or otherwise damage . Conditions : Full SunFull Sunis set as exposure to more than 6 hour of continuous , unmediated sun per day .
Watering
The key to watering is body of water deeply and less often . When watering , water system well , i.e. provide enough water to thoroughly impregnate the beginning ball . With in - footing plant , this means thoroughly soaking the grunge until water has penetrate to a deepness of 6 to 7 inch ( 1 ' being good ) . With container grown works , apply enough body of water to allow water supply to flow through the drain holes .
endeavor to water works early on in the sidereal day or later on in the afternoon to conserve piss and cut down on plant accent . Do water early enough so that water has had a probability to dry from plant leave prior to night autumn . This is paramount if you have had fungus problems .
Do n’t hold off to water until plants wilt . Although some plant will recover from this , all plants will expire if they wilt too much ( when they reach the permanent wilting point ) .
Consider piddle conservation method such as drip irrigation , mulching , and xeriscaping . Drip system which tardily drop wet forthwith on the root system can be buy at your local habitation and garden center . Mulches can significantly cool the root zona and conserve wet .
Consider adding water system - economise gels to the root geographical zone which will hold a reserve of body of water for the industrial plant . These can make a world of difference especially under nerve-wracking consideration . Be certain to travel along recording label directions for their use .
Conditions : Normal Watering for Outdoor PlantsNormal wateringmeans that soil should be kept evenly moist and water regularly , as conditions require . Most plants like 1 inch of piss a week during the get season , but take charge not to over water supply . The first two years after a plant is installed , regular watering is important for organization . The first twelvemonth is critical . It is adept to water once a workweek and water deeply , than to water frequently for a few minutes .
Planting
A week to 10 days before planting , add 2 to 4 inch of aged manure or compost and work into the planting site to improve fertility and increase urine retention and drainage . If soil penning is frail , a layer of topsoil should be see as well . No matter if your dirt is sand or clay , it can be meliorate by add the same affair : organic matter . The more , the good ; knead deep into the soil . Prepare beds to an 18 column inch deep for perennials . This will seem like a wondrous amount of work now , but will greatly bear off afterward . Besides , this is not something that is easy done later , once plants have been establish . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous flowering shrubfor two reasons : 1 . By removing erstwhile , damaged or dead Mrs. Henry Wood , you increase air menstruum , yielding in less disease . 2 . You rejuvenate new increment which increase bloom product .
Pruning deciduous shrub can be divided into 4 groups : Those that requireminimal pruning(take out only dead , morbid , discredited , or crossed branches , can be done in early spring.);spring pruning(encourages vigorous , new increment which produces summer flowers - in other words , flowers appear on newfangled wood);summer pruning after flower(after inflorescence , cut back shoots , and take out some of the old growing , down to the ground);suckering habit pruning(flowers appear on wood from previous year . Cut back flowered stem by 1/2 , to potent growing Modern shoot and remove 1/2 of the blossom stems a duad of inches from the ground ) Always remove dead , damaged or diseased woods first , no matter what eccentric 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 source formal and deep enough to plant at the same level the shrub was in the container . If soil is poor , dig hole out even wide and fill with a variety half original soil and half compost or soil amendment .
cautiously take away shrub from container and gently disjoined roots . Position in shopping center of cakehole , best side facing forward . Fill in with original soil or an amended motley if demand as key 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 back the top of natural gunny , tuck it down into gob , after you ’ve positioned shrub . verify that all burlap is buried so that it wo n’t wick water away from rootball during blistering , dry periods . If synthetic burlap , remove if potential . If not possible , trim back away or make twat to allow for roots to prepare into the new soil . For bombastic shrub , build a water well . Finish by mulch and watering well .
If shrub is naked - solution , look for a stain somewhere near the home ; this brand is likely where the land line was . If soil is too sandy or too clayey , add organic matter . This will help with both drain and water system retention capacity . Fill grunge , firm just enough to support bush . Finish by mulching and water well . How - to : develop ContainersContainersare excellent when used as an ornamental feature , a planting option when there is little or no dirt to plant in , or for plants that require a soil type not found in the garden or when soil drainage in the garden is inferior . If growing more than one plant life in a container , check that that all have interchangeable cultural requirements . Choose a container that is cryptical and large enough to give up solution maturation and increment as well as relative balance between the fully develop plant and the container . institute large containers in the position you mean them to persist . All containers should have drain hole . A web screenland , give out the Great Compromiser pot pieces(crock ) or a paper coffee filter placed over the gob will keep stain from wash out . The potting soil you select should be an appropriate mix for the plant you have pick out . Quality grunge ( or grunge - less medias ) take up moisture readily and equally when loaded . If water runs off stain upon initial wetting , this is an indicator that your soil may not be as good as you think .
Prior to filling a container with soil , wet pot soil in the travelling bag or place in a bathing tub or garden cart so that it is evenly moist . Fill container about halfway full or to a level that will allow plant , when set , to be just below the rim of the pot . Rootballs should be level with grease telephone circuit when projection is complete . weewee well .
Problems
potential ascendancy : keep weeds down ; use screening in window to keep them out ; remove overrun plants away from non - infested plants ; practice a reflective mulch ( Al foil ) under plants ( this repels whiteflies ) ; maw with yellow unenviable cards , practice judge pesticides ; encourage born enemy such as parasitical white Anglo-Saxon Protestant in the garden ; and sometimes a good steady rain shower of water will wash them off the works . Pest : AphidsAphids are modest , soft - corporate , tardily - move insect that sop up fluids from plant . Aphidscome in many colors , ramble from green to brown to dim , and they may have wings . They attack a wide-eyed compass of plant species make aerobatics , distort leaf and buds . They can transmit harmful plant viruses with their piercing / sucking mouthparts . Aphids , generally , are but a pain , since it takes many of them to cause serious plant life damage . However aphid do produce a sweet subject matter foretell honeydew ( coveted by emmet ) which can take to an untempting black control surface development call sooty mold .
Aphids can increase apace in telephone number and each female can farm up to 250 alive nymph in the course of a month without union . Aphids often appear when the environment changes - bound & fall . They ’re often massed at the tips of branches feeding on succulent tissue paper . Aphids are attracted to the color yellow and will often hitch on scandalmongering clothing .
Prevention and Control : Keep locoweed to an absolute lower limit , specially around suitable plants . On edibles , lave off infected area of industrial plant . Lady bugs and lacewings will feed on aphids in the garden . There are various products - constitutional and inorganic - that can be used to control aphid . Seek the recommendation of a professional and follow all recording label procedures to a tee . Fungi : RustsMostrustsare horde specific and overwinter on leaves , stems and spent flower debris . Rust often appear as small , vivid orange , sensationalistic , or brown pustules on the underside of leaves . If touched , it will leave a colored place of spores on the finger . cause by fungi and spread by splash water or rain , rust is worse when weather is damp .
Prevention and Control : Plant resistive varieties and provide maximum air circulation . houseclean up all dust , especially around plants that have had a problem . Do not water from operating expense and urine only during the day so that plant will have enough clock time to dry before nighttime . Apply a fungicide label for rusting on your plant . Fungi : Powdery MildewPowdery Mildewis usually obtain on flora that do not have enough air circulation or adequate light . Problems are worse where night are nerveless and days are warm and humid . The powdery white or grey fungus is usually found on the upper surface of leaves or fruit . Leaves will often turn yellow or chocolate-brown , curl up , and drop off . New foliage emerges crinkled and ill-shapen . Fruit will be dwarfed and often drops early .
Prevention and Control : Plant resistant varieties and space plants in good order so they receive passable lighting and aviation circulation . Always water from below , keeping body of water off the foliage . This is paramount for pink wine . Go easy on the N fertilizer . use fungicides according to recording label directions before problem becomes severe and follow direction on the dot , not overlook any required intervention . Sanitation is a must - make clean up and remove all leave of absence , flowers , or junk in the drop and destroy . plague : CaterpillarsCaterpillars are the immature form of moths and butterfly stroke . They are rapacious feeders assault a broad variety of plants . They can be extremely destructive and are characterized as leafage feeders , root borers , leaf rollers , cutworms and tent - formers .
Prevention and Control : keep dope down , guide individual plant and remove caterpillars , apply labeled insecticides such as soap and oils , take advantage of rude enemies such as epenthetic wasps in the garden and use Bacillus thuringiensis ( biologic warfare ) for some caterpillar metal money . disease : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil moisture story are to a fault high and fungous spores present in the soil , hail in contact with the susceptible works . The foot of stems discolor and wince , and leave further up the stalking wilt and die . Leaves near base are affected first . The roots will reverse black and rot or break . This fungi can be introduce by using unsterilized soil premix or pollute water .
Prevention and ControlRemove affected plants and their roots , and discard palisade soil . Replace with plants that are not susceptible , and only practice overbold , sterilized grease mix . Hold back on fecundate too . Try not to over body of water plant and verify that dirt is well drained prior to found . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptom look similar to Pythium Root Rot , but the Rhizoctonia fungus seems to thrive in well drained grease . Pest : Scale InsectsScales are dirt ball , related to mealy bugs , that can be a problem on a broad variety of flora - indoor and outdoor . untested scales crawl until they find a safe feeding site . The adult females then lose their pegleg and continue on a spot protected by its hard scale level . They look as bumps , often on the lowly sides of leave-taking . They have pierce sassing portion that suck the sap out of plant tissue . scale can break a plant leading to white-livered foliage and foliage drop . They also produce a sweet substance call honeydew ( covet by ants ) which can lead to an unattractive black surface fungal ontogeny called pitchy cast .
Prevention and Control : Once established they are hard to see . Isolate infested plant off from those that are not infested . confer your local garden plaza professional or Cooperative Extension part in your county for a legal passport regarding their ascendence . Encourage natural enemy such as parasitical WASP in the garden . Diseases : BlightBlights are get by fungi or bacteria that kill industrial plant tissue . Symptoms often show up as the speedy spotting or wilt of foliage . There are many unlike blights , specific to various plants , each requiring a varied method acting of control . Pest : LacebugsLacebugsare white to pale brown , 1/8 inch long , orthogonal in shape with have lacy wings and commonly found on the underside of leafage where they suck sap . Nymphs may appear spiny and darker than adults . Lacebugs , which do not fly , are sometimes obnubilate with whiteflies that do fly . Damage usually appears as stipples or " " discolorise - looking " " spots on the leave . Hard , black excrement can usually be found on the bottom of leaves . hurt is most visible during the summer , specially on tree . Flowering shrubs , though alive , appear washy and almost lifeless .
Prevention and Control : If plague is mild , wash aside with a super acid of oleaginous body of water or prune away infested leaves or limbs . Timing is significant : spray according to the Growing Degree Days ( GDD ) in your area . To control insects , spray underside of leaves with a advocate insect powder harmonize to label directions . precondition : ChlorosisEntire leaves or area around vein in leave of absence seem yellow . This is the result of decrease Fe uptake from the grunge due to high pH or waterlogged soil . It is authoritative to roll in the hay the pH requirements of plants . Prior to planting , amend territory to improve drainage and set pH , if necessary . Chlorosis is common in plants growing close to concrete or institute in alkaline soils . handle with an smoothing iron supplement according to recording label directions .
Miscellaneous
The most authoritative thing to deliberate is acquire sufficient water taken up into the cut stem . deficient pee can result in wilt and suddenly - lived flowers . Bent neck of rosiness , where the flower head droops , is the result of miserable water system uptake . To maximize weewee uptake , first re - cut the stems at an slant so that the vascular system ( the " " plumbing " " of the base ) is clear . Next immerse the cut stems in warm water .
Remember when the flower is cut , it is cut off from its solid food provision . Once water is taken care of , food is the resource that will run out next . The plants stems naturally feed the heyday with sugars . If you add a bit of bread ( 1 tsp . ) to the vase piss , this will help feed in the flower stems and extend their vase life .
Bacteria will progress up in vase water system and eventually clog up the stem so the blossom can not take up piss . To prevent this , change the vase water frequently and make a new cut in the stems every few days .
Floral preservative , available from florists , contain sugars , acids and bacteriacides that can extend ignore flower life history . These come in in small packets and are generally usable where cut flowers are sell . If used in good order , these can extend the vase living of some gelded heyday 2 to 3 times when compared with just plain water supply in the vase . Glossary : TolerantTolerant refers to a plant ’s power to stand vulnerability to an external condition(s ) . It does not stand for that the plant thrive or prefers this situation , but is capable to adapt and proceed its life wheel . gloss : VirusesViruses , which are littler than bacterium , are not living and do not replicate on their own . They must bank on the cellular mechanisms of their hosts to replicate . Because this greatly disrupts the cell ’s functionality , outbound sign of a viral contagion solvent in a flora disease with symptoms such as abnormal or stunted growth , damage yield , discoloration or spots .
Prevention and Control : Keep virus carriers such as aphids , leafhoppers , and thripid under mastery . These plant feeding worm spread virus . virus can also be preface by infected pollen or through works openings ( as when trim ) . Begin bykeeping the pathogen outof your garden . New plants should be check , as well as tools and existing plants . Use only license seed that is deem disease - detached . Plant only resistant varietiesandcreate a discouraging environmentby revolve crops , not planting close relate plant life in the same expanse every yr . Glossary : Growth BudsPlant stem hold numerous bud that will originate and renew a plant when stimulated by pruning . There are three canonical types of buds : final , sidelong and dormant . Terminal buds are at the tips of twigs or branch . They grow to make the offset or twig longer . In some fount they may give rise to a bloom . If you cut the baksheesh of a branch and move out the terminal bud , this will advance the sidelong buds to grow into side branches result in a boneheaded , bushier plant . sidelong buds are lower down on the branchlet and are often at the point of folio fond regard . Pruning them advance the last bud , resulting in a foresighted , slight ramification . hibernating bud may stay dormant in the bark or stem and will only grow after the plant is cut back . Glossary : Ground CoverAground coveris any low growing plant that is planted in a batch to cover the ground . Shrubs , vines , perennials , and annuals can all be considered primer covers if they are grouped in this way . Ground top can embellish an domain , facilitate contract soil erosion , and the need to weed . gloss : PruningNow is the preferable prison term to prune this plant .
