Upright , deciduous bush that is cold hardy from -10 to -20 degrees F. Single , trumpet - shaped , pinkish flower , 2 to 3 inch wide . leaf are elliptic to oblong , 2 to 6 inches long . heyday are borne in bombastic , showy trusses from early to tardy spring . The deciduous hybrid azalea , like it ’s aboriginal similitude , is known for excellent fall colour and unexceeded spring blossom . The deciduous azalea is ordinarily less picky about stain conditions , though it too prefers well - drained and acerb conditions . The Ilam azaleas are hybrids developed in New Zealand resulting from cross between R. molle , R. calendulaceum , and R. viscosum . Though azalea have a potentially big list of potential pest and disease problem , they are usually hassle - free if constitute correctly in right cultural conditions .

Light
You will notice that sun and shade design alter during the day . The western side of a house may even be shady due to shadows throw by large Tree or a bodily structure from an contiguous belongings . If you have just bought a new home or just beginning to garden in your onetime house , take time to map sun and shade throughout the day . You will get a more exact feel for your site ’s unfeigned light term . weather : Filtered LightFor many plants that favor partially shady experimental condition , strain lightis nonpareil . Good planting internet site are under a mid to large sized tree that lets some light source through their branch or beneath taller plants that will provide some protection . Conditions : Partial Sun , Partial ShadePart sunorpart shadeplants prefer luminousness that is filtered . Sunlight , though not direct , is important to them . Often first light sun , because it is not as unassailable as good afternoon sun , can be considered part sun or part tad . If you live in an region that does not get much acute sun , such as the Pacific Northwest , a full sun vulnerability may be all right . In other areas such as Florida , industrial plant in a locating where afternoon tincture will be receive . Conditions : Full to Partial SunFull sunlightis call for for many plants to assume their full potentiality . Many of these plants will do fine with a little less sunshine , although they may not blossom as hard or their leafage as vibrant . arena on the southerly and western face of building usually are the sunniest . The only exception is when house or buildings are so near together , shadows are vagabond from neighboring prop . Full sunlight usually means 6 or more hours of lineal unobstructed sunlight on a cheery day . Partial Lord’s Day receive less than 6 time of day of sun , but more than 3 hours . Plants able-bodied to take full sunlight in some climates may only be capable to allow part sun in other climate . Know the polish of the plant before you purchase and plant it!Conditions : Types of PruningTypes of pruning include : pinching , thinning , shearing and rejuvenating .
Pinching is removing the stem tips of a new industrial plant to promote branching . Doing this avoid the need for more wicked pruning later on .
cutting demand removing whole branches back to the body . This may be done to open up up the inside of a plant to let more ignitor in and to increase air circulation that can cut down on plant disease . The best fashion to begin cutting is to begin by removing dead or pathologic wood .
Shearing is level the aerofoil of a bush using hired man or electric shear . This is done to keep the desire configuration of a hedge or topiary .
Rejuvenating is removal of old branch or the overall reduction of the size of a shrub to repair its original manikin and size . It is recommended that you do not remove more than one third of a industrial plant at a clock time . Remember to move out branch from the inside of the industrial plant as well as the outside . When rejuvenating plants with canes , such as nandina , cut back canes at various heights so that flora will have a more natural flavor . condition : Full SunFull Sunis define as exposure to more than 6 hours of uninterrupted , direct Lord’s Day per day .
Watering
The key to watering is water deeply and less frequently . When tearing , water well , i.e. provide enough H2O to thoroughly impregnate the theme ball . With in - earth plants , this entail thoroughly soaking the grunge until weewee has penetrated to a depth of 6 to 7 inches ( 1 ' being better ) . With container grown plant life , enforce enough water to allow water to flow through the drainage holes .
attempt to irrigate plants early in the day or later in the good afternoon to economize water and trim down on industrial plant tenseness . Do water early enough so that water system has had a fortune to dry from plant leave-taking prior to nighttime fall . This is predominant if you have had fungus job .
Do n’t wait to water until plants wilt . Although some plants will recover from this , all plants will die if they wilt too much ( when they strive the lasting wilting peak ) .
Consider pee preservation method acting such as dribble irrigation , mulching , and xeriscaping . drip mould system which slowly dribble wet directly on the solution scheme can be purchased at your local home and garden center . Mulches can importantly cool the root zone and conserve wet .
Consider adding water - make unnecessary gelatin to the ascendant zone which will hold a reserve of water for the plant . These can make a human beings of difference particularly under stressful conditions . Be certain to follow recording label counsel for their usage .
stipulation : Normal Watering for Outdoor PlantsNormal wateringmeans that soil should be kept evenly moist and water on a regular basis , as condition need . Most industrial plant like 1 column inch of pee a calendar week during the growing time of year , but take care not to over water . The first two years after a plant is installed , regular watering is important for establishment . The first year is critical . It is unspoilt to water once a hebdomad and water deeply , than to weewee oft for a few minutes .
Planting
A week to 10 day before planting , add 2 to 4 column inch of aged manure or compost and work into the planting site to better fertility and increase piddle retention and drainage . If stain constitution is weak , a layer of topsoil should be moot as well . No matter if your filth is sand or Henry Clay , it can be improved by adding the same thing : organic matter . The more , the good ; work deep into the soil . Prepare bed to an 18 in deep for perennials . This will seem like a wondrous amount of work now , but will greatly devote off later . Besides , this is not something that is easily done later , once plant have been established . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous anthesis shrubfor two reasons : 1 . By removing old , damaged or idle wood , you increase air flow , grant in less disease . 2 . You rejuvenate new growth which increase prime output .
Pruning deciduous shrubs can be divided into 4 groups : Those that requireminimal pruning(take out only utter , diseased , discredited , or cut across branch , can be done in early spring.);spring pruning(encourages vigorous , Modern outgrowth which produces summer flowers - in other word , flowers appear on raw wood);summer pruning after flower(after blossoming , cut back shoots , and take out some of the old ontogenesis , down to the ground);suckering substance abuse pruning(flowers seem on wood from previous class . Cut back flowered stems by 1/2 , to strong growing novel shoots and remove 1/2 of the blossom stems a twain of in from the ground ) Always remove idle , damaged or diseased woods 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 . summertime after heyday : 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 the source ball and rich enough to plant at the same level the bush was in the container . If soil is poor , dig hole out even wider and fill with a mixture half original filth and half compost or ground amendment .
Carefully polish off shrub from container and gently freestanding root . Position in center of hole , better side confront forward . replete in with original soil or an better potpourri if need as described above . For larger shrubs , build a urine well . Finish by mulch and watering well .
If the plant is ball - and - burlapped , remove fastener and fold back the top of lifelike gunny , insert it down into hole , after you ’ve positioned bush . verify that all burlap is immerse so that it wo n’t wick piddle by from rootball during hot , dry periods . If synthetical gunny , remove if possible . If not possible , cut away or make slits to allow for roots to develop into the new grunge . For larger shrub , build a water system well . Finish by mulching and watering well .
If shrub is bare - root , face for a discoloration somewhere near the base ; this mark is likely where the soil seam was . If soil is too sandy or too clayey , add constituent issue . This will help with both drainage and water keeping capacity . Fill soil , tauten just enough to support shrub . Finish by mulching and irrigate well .
Problems
Possible controls : keep weeds down ; use screening in windows to keep them out ; take away infested plant away from non - infested plants ; use a reflective mulch ( atomic number 13 foil ) under plant ( this repels whiteflies ) ; hole with yellow-bellied sticky batting order , implement labeled pesticides ; encourage natural enemy such as parasitical wasps in the garden ; and sometimes a sound steady shower of body of water will wash them off the plant . Pest : AphidsAphids are small , soft - bodied , behind - moving insects that take in fluids from plant . Aphidscome in many coloration , ranging from green to brown to inglorious , and they may have wing . They set on a encompassing range of plant species induce stunting , deform leaves and buds . They can transmit harmful plant viruses with their piercing / sucking mouthpart . Aphids , broadly speaking , are but a pain in the neck , since it takes many of them to do serious industrial plant damage . However aphid do bring forth a honeyed substance call honeydew ( coveted by ants ) which can lead to an unattractive bleak airfoil growth called sooty cast .
Aphids can increase cursorily in numbers and each female can produce up to 250 live nymph in the form of a calendar month without mating . Aphids often appear when the environs alter - spring & fall . They ’re often mass at the tips of branches feeding on lush tissue paper . Aphids are attracted to the color yellow and will often hitchhike on yellow habiliment .
Prevention and Control : Keep weeds to an absolute lower limit , especially around desirable plants . On edible , wash off infected area 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 . Seek the recommendation of a professional and follow all recording label procedures to a tee . fungus : RustsMostrustsare horde specific and overwinter on leaves , halt and spent flower debris . Rust often appear as small , smart orangish , yellow , or brown pustules on the undersurface of leaves . If touched , it will leave a one-sided spot of spore on the finger . do by fungi and spread by splashing water or rain , rust is speculative when conditions is dampish .
Prevention and Control : Plant tolerant varieties and render maximum air travel circulation . strip up all debris , especially around flora that have had a job . Do not water from disk overhead and water only during the day so that plants will have enough clock time to dry before night . Apply a antimycotic labeled for rust fungus on your plant . Fungi : Powdery MildewPowdery Mildewis ordinarily set up on plant that do not have enough air circulation or fair to middling light . Problems are worse where night are cool and daylight are strong and humid . The powdery snowy or grey-headed fungus is ordinarily found on the upper surface of farewell or fruit . Leaves will often wrench yellow or brown , wave up , and drop off . raw leafage emerges crease and distorted . Fruit will be shadow and often drops early .
Prevention and Control : Plant insubordinate varieties and blank space plants decent so they find adequate light and aura circulation . Always water from below , keep H2O off the leaf . This is paramount for pink wine . Go slowly on the N fertilizer . Apply fungicides according to label directions before problem becomes severe and observe directions precisely , not missing any take intervention . Sanitation is a must - make clean up and take away all leaves , flowers , or debris in the twilight and put down . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil wet tier are excessively high and fungal spores present in the stain , come in contact with the susceptible plant . The foot of stems discolor and shrink , and leaves further up the stalk wilt and die . foliage near base are bear on first . The ascendent will turn black and molder or break . This fungi can be introduce by using unsterilised soil mix or contaminated water .
Prevention and ControlRemove affected works and their roots , and discard circumvent soil . exchange with plants that are not susceptible , and only practice fresh , sterilized soil mixture . obligate back on feed too . essay not to over water plants and make indisputable that dirt is well enfeeble prior to planting . This fungus is not treatable by chemical substance .
Rhizoctonia Root and Stem Rot symptoms search similar to Pythium Root Rot , but the Rhizoctonia fungus seems to fly high in well drained grease . Fungi : Leaf SpotsLeaf spots are cause by kingdom Fungi or bacteria . browned or black spots and patch may be either ragged or circular , with a piss hit it up or yellow - edged coming into court . worm , rainwater , dirty garden puppet , or even people can help its spread .
Prevention and Control : absent infected leaves when the plant is ironic . leave-taking that collect around the base of the flora should be raked up and disposed of . Avoid overhead irrigation if possible ; water should be aim at land level . For fungal leaf topographic point , use a recommend fungicide concord to label directions .
fungus kingdom : Black SpotA known rose disease , Black Spotappears on young leave as irregular black circles , often hold a yellow halo . circle or spore settlement may grow to 1/2 inch in diam . Leaves will release yellow and flatten off , only to grow more leave that will follow the same pattern . rose wine may not make it through the wintertime if black spot is spartan . The fungus will also affect the size and timber of flower .
Prevention and Control : Plant resistant varieties for your area . Always water system from the ground , never overhead . Practice good sanitation - clean up and destruct debris , especially around plants that have had a problem . When trim roses , even deadheading , drop pruners in a bleach / water supply root after each cut . If a plant seems to have chronic dark spot , off it . A 2 - 3 in thick bed of mulch at the base of works concentrate splashing . Do not look until black place is a vast problem to ensure ! Start too soon . Spray with a fungicide labeled for smutty maculation on rosiness . Pest : Scale InsectsScales are insect , bear on to mealy bugs , that can be a problem on a wide mixture of plants - indoor and outside . Young scales crawl until they observe a good alimentation site . The adult females then misplace their legs and remain on a speckle protect by its difficult shell stratum . They appear as bumps , often on the low-pitched sides of leave . They have pierce backtalk parts that suck up the sap out of plant tissue paper . Scales can undermine a plant head to sensationalistic foliation and leaf drop cloth . They also give rise a sweet substance called honeydew ( covet by ants ) which can head to an untempting black surface fungous increase called jet mold .
Prevention and Control : Once established they are hard to control . Isolate infest works away from those that are not infested . Consult your local garden center professional or Cooperative Extension spot in your county for a effectual recommendation regarding their control . Encourage natural enemies such as parasitic wasps in the garden . disease : BlightBlights are induce by kingdom Fungi or bacteria that kill plant tissue paper . symptom often show up as the rapid spotting or wilting of foliage . There are many different blight , specific to various plants , each requiring a varied method of mastery . Pest : LacebugsLacebugsare blank to pale brown , 1/8 column inch long , rectangular in shape with have lacy wing and usually find on the underside of leaves where they suck up sap . Nymphs may appear spiny and darker than grownup . Lacebugs , which do not vanish , are sometimes confused with whiteflies that do fly . Damage usually appears as stipples or " " bleach out - looking " " spots on the leave . severely , disgraceful excreta can usually be found on the undersurface of leaves . Damage is most seeable during the summer , especially on Tree . Flowering shrubs , though live , seem weak and almost exanimate .
Prevention and Control : If infestation is soft , wash out with a jet of soapy piss or prune off infested leaves or limb . Timing is important : spray harmonise to the Growing Degree Days ( GDD ) in your region . To control dirt ball , spray underside of leave with a recommended insecticide according to label directions . shape : ChlorosisEntire folio or area around mineral vein in leaf appear yellow . This is the answer of decreased iron intake from the soil due to higher pH or waterlogged soil . It is important to have it off the pH requirements of industrial plant . Prior to planting , amend soil to improve drainage and line up pH , if necessary . greensickness is mutual in plants growing nigh to concrete or planted in alkaline dirt . Treat with an iron supplement according to label counselling . Fungi : Downy MildewDowny Mildew , a fluffy white fungal growth that develop on the underside of leaves , is most common during cool , humid conditions . Foliage often discolors and is stunt .
Prevention and Control : utilize disease free industrial plant and space far enough apart so that air circulation is good . Remove and discard infected leaves or even entire plants . Use a recommend fungicide and always follow the direction on the label .
Miscellaneous
Although many citizenry consider that cooler temperature are responsible for the color variety , the weather condition has nothing to do with it at all . As the days grow short and the nighttime longer , a chemical clock inside the trees starts up , releasing a hormone which confine the flow of sap to each leaf . As decline progresses , the sap flow slows and chlorophyl , the chemical substance that give the leave of absence their green color in the natural spring and summer , go away . The residual cosh becomes more concentrated as it dries , create the colors of fall . gloss : Low MaintenanceLow maintenancedoes not entail no maintenance . It does mean that once a plant is establish , very little needs to be done in the way of pee , fertilizing , pruning , or treatment in order for the plant to stay healthy and attractive . A well - designed garden , which takes your modus vivendi into consideration , can greatly reduce maintenance . Glossary : Mass PlantingMass is one of the elements of design and relate direct to balance . Mass planting is define as the grouping of three or more of the same type of plants in one domain . When massing plant life , keep in mind what visual effect they will have . Small properties require small masses where expectant properties can manage larger masses or sweeps of plants . gloss : SpecimenAspecimencan be a tree , shrub , undercoat screen , annual , or repeated that is unique in comparison to the border plant . singularity may be in color , signifier , texture , or size . By using only one specimen plant in a visual area , it can be showcased . Specimen plants are accents in the landscape , just as statue , water system feature , or arbors .

Glossary : Long LastingLong Lasting : having blossoms that last for an extensive stop of metre . Some works may have the visual aspect of providing foresightful lasting flowers because they are fertile , repeat bloomers . Glossary : pHpH , means the potential of Hydrogen , is the measure of alkalinity or sour . In gardening , pH refers to the pH of soil . The musical scale measures from 0 , most acid , to 14 , most alkaline . Seven is neutral . Most plant prefer a range between 5.5 and about 6.7 , an acid reach , but there are plenty of other works that like soil more alkaline , or above 7 . A pH of 7 is where the plant can most easily ingest the most food in the soil . Some plants favour more or less of sealed nutrients , and therefore do better at a certain pH.Glossary : Plant CharacteristicsPlant characteristics define the flora , enable a hunt that rule specific eccentric of plants such as bulbs , tree , shrubs , grass , perennials , etc . gloss : Flower CharacteristicsFlower characteristics can vary greatly and may serve you decide on a " " look or feel " " for your garden .

How - to : get the Most Out of Cut FlowersCut blossom bring the garden into your nursing home . While some cut flowers have a farseeing vase life-time , most are extremely perishable . How prune flowers are treated when you first bestow them home can significantly increase how long they last .
The most important thing to consider is acquire sufficient body of water taken up into the gash stem . Insufficient water system can result in wilting and short - live flowers . Bent neck of roses , where the blossom head droops , is the result of poor piddle intake . To maximize water uptake , first re - cut the stem at an slant so that the vascular system ( the " " plumbing system " " of the stem ) is clear . Next immerse the cut stem in fond water .
Remember when the efflorescence is dilute , it is cut off from its food provision . Once water is taken aid of , food is the imagination that will scat out next . The plant life stems naturally feed the flowers with sugars . If you add a bit of sugar ( 1 tsp . ) to the vase water , this will help feed the flush staunch and extend their vase life sentence .
Bacteria will build up in vase water and eventually clog up the stem so the bloom can not take up water . To prevent this , change the vase body of water frequently and make a new cut in the stems every few days .
flowered preservative , available from florists , contain sugars , acids and bacteriacides that can extend dilute flower lifetime . These come in little packet and are generally available where cut flowers are sold . If used decently , these can extend the vase life of some cut flowers 2 to 3 times when compared with just unmistakable pee in the vase . Glossary : TolerantTolerant refers to a industrial plant ’s ability to tolerate exposure to an outside condition(s ) . It does not mean that the works expand or prefers this situation , but is able to accommodate and continue its life wheel . gloss : VirusesViruses , which are lowly than bacterium , are not go and do not reduplicate on their own . They must rely on the cellular mechanisms of their emcee to replicate . Because this greatly disrupts the cell ’s functionality , outbound signs of a viral contagion result in a plant life disease with symptom such as abnormal or stunted maturation , damage fruit , discolorations or spot .
Prevention and Control : Keep virus carrier such as aphid , leafhoppers , and thrips under control . These works feeding insects circulate viruses . virus can also be introduced by infected pollen or through plant openings ( as when crop ) . Begin bykeeping the pathogen outof your garden . New plants should be tick , as well as dick and existing plant . apply only certified seed that is take for disease - gratis . industrial plant only immune varietiesandcreate a discouraging environmentby rotating crop , not planting intimately related plants in the same expanse every yr . Glossary : PruningNow is the preferred time to dress this industrial plant .
