Small , bushy , evergreen plant azalea with lush , shiny , dark green leaves , 1 1/4 to 1 3/4 inches long . Double , funnel - shaped , purplish heyday , 2 1/2 to 3 inches blanket . bloom are carry copiously in large , showy trusses from late winter to early spring . plant life as you would any of the other azaleas : high and in well - drain , acid soil , rich with organic topic . first-class choice for growing indoors in container . Can be develop outdoors where winter temperatures do not fall below 20 level F. The Belgian Indica azaleas are the termination of crosses between many different species , include R. sinsii , R. mucronatum , and R. indicum . They were to begin with bred as glasshouse coerce plants . This hybrid is primarily grown in Australia and New Zealand . Though azaleas have a potentially prominent tilt of potential pest and disease problem , they are usually trouble - detached if plant correctly in right ethnic conditions .

Light
You will find that sun and shade patterns change during the day . The western side of a house may even be shadowed due to tincture be sick by large tree or a social system from an adjacent property . If you have just bought a new home or just beginning to garden in your older family , take sentence to map sun and shade throughout the day . You will get a more accurate look for your site ’s true tripping conditions . condition : Filtered LightFor many plant that prefer partially shady precondition , filtered lightis ideal . just planting sites are under a mid to large sized tree that lease some light through their branches or beneath improbable works that will provide some protection . Conditions : Partial Sun , Partial ShadePart sunorpart shadeplants prefer light that is filtered . Sunlight , though not direct , is important to them . Often morning Sunday , because it is not as strong as afternoon sun , can be considered part sun or part refinement . If you live in an area that does not get much intense sun , such as the Pacific Northwest , a full Lord’s Day photo may be fine . In other areas such as Florida , plant in a location where afternoon shade will be received . consideration : Full to Partial SunFull sunlightis needed for many flora to bear their full potential difference . Many of these industrial plant will do very well with a little less sunshine , although they may not flower as intemperately or their foliation as vibrant . Areas on the southerly and westerly slope of construction usually are the sunniest . The only exception is when house or buildings are so close together , shadow are cast from neighboring dimension . Full sun unremarkably means 6 or more 60 minutes of direct unobstructed sun on a cheery twenty-four hours . fond sun receives less than 6 hour of sun , but more than 3 hour . Plants able to take full Sunday in some climate may only be able-bodied to permit part sun in other climates . Know the culture of the plant before you buy and plant it!Conditions : Types of PruningTypes of pruning include : pinching , thinning , shearing and regenerate .
Pinching is removing the stem tips of a young plant life to promote branching . Doing this ward off the need for more severe pruning later on .
cutting involve removing whole branches back to the bole . This may be done to spread out up the DoI of a industrial plant to have more luminance in and to increase air circulation that can cut down on works disease . The right way to begin thinning is to begin by removing dead or diseased woods .
Shearing is leveling the open of a shrub using hand or electric shears . This is done to keep the desire pattern of a hedge or topiary .
rejuvenate is removal of old arm or the overall reduction of the size of a bush to restore its original kind and size . It is recommended that you do not remove more than one third of a flora at a prison term . Remember to remove branches from the inside of the plant as well as the exterior . When rejuvenating plants with canes , such as nandina , cut back canes at various height so that works will have a more natural look . condition : Light and Plant SelectionFor skilful flora performance , it is suitable to twin the right plant with the useable wanton conditions . correct plant , correct position ! works which do not receive sufficient twinkle may become pallid in colour , have fewer leaves and a " leggy " stretched - out appearance . Also gestate plants to spring up slower and have few blooms when light is less than desirable . It is possible to provide supplemental light for indoor plants with lamps . works can also encounter too much light . If a shadowiness loving plant is exposed to unmediated Lord’s Day , it may wilt and/or make leaves to be sunburned or otherwise damaged . Conditions : Full SunFull Sunis defined as exposure to more than 6 hours of uninterrupted , unmediated sun per daylight .
Watering
The key to watering is water system deeply and less often . When lacrimation , piddle well , i.e. provide enough water to thoroughly saturate the root ball . With in - primer coat plant , this means soundly douse the dirt until water has penetrated to a depth of 6 to 7 column inch ( 1 ' being better ) . With container grown plant , apply enough water to allow water to run through the drainage holes .
seek to water plants early in the day or subsequently in the afternoon to economize weewee and cut down on plant emphasis . Do water betimes enough so that water has had a fortune to dry from plant leaves prior to night fall . This is paramount if you have had fungus problem .
Do n’t expect to water until plant life wilt . Although some plants will recuperate from this , all plants will die if they droop too much ( when they reach the permanent wilting point ) .
Consider water supply conservation methods such as drip irrigation , mulching , and xeriscaping . dribble systems which slowly drop wet directly on the root system can be purchase at your local home and garden marrow . Mulches can significantly cool the root zona and conserve moisture .
see adding water - saving gel to the root geographical zone which will hold a reserve of water for the plant . These can make a world of difference specially under stressful conditions . Be certain to follow label focusing for their use .
Conditions : Normal Watering for Outdoor PlantsNormal wateringmeans that soil should be kept evenly moist and watered on a regular basis , as term command . Most plants like 1 inch of water a calendar week during the maturate season , but take care not to over water . The first two years after a plant is install , unconstipated watering is significant for brass . The first year is decisive . It is better to water supply once a workweek and water profoundly , than to water supply oftentimes for a few minutes .
Planting
A week to 10 day before planting , add 2 to 4 inches of older manure or compost and work into the planting website to meliorate fertility and increase water retentivity and drain . If soil musical composition is feeble , a level of topsoil should be considered as well . No matter if your territory is sand or clay , it can be better by adding the same affair : organic thing . The more , the better ; forge deeply into the dirt . Prepare beds to an 18 inch deep for perennials . This will seem like a grand amount of oeuvre now , but will greatly pay 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 blossoming shrubfor two grounds : 1 . By removing old , discredited or dead Grant Wood , you increase air flow , yielding in less disease . 2 . You rejuvenate new ontogenesis which increases flower production .
Pruning deciduous shrubs can be divided into 4 groups : Those that requireminimal pruning(take out only dead , morbid , damaged , or crossed branches , can be done in early spring.);spring pruning(encourages vigorous , young growing which produce summer flowers - in other words , flowers seem on raw wood);summer pruning after flower(after inflorescence , cut back shoot , and take out some of the honest-to-god maturation , down to the ground);suckering habit pruning(flowers appear on wood from previous year . Cut back flowered stems by 1/2 , to strong develop unexampled shoot and absent 1/2 of the flowered stems a couple of inches from the ground ) Always remove utter , damaged or pathologic Sir Henry 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 . summertime 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 glob and deep enough to plant at the same level the bush was in the container . If dirt is poor , dig hole even wider and fill with a mixture half original soil and half compost or soil amendment .
Carefully remove shrub from container and gently separate rootage . Position in kernel of hole , best side facing forward . Fill in with original soil or an amended mixture if need as described above . For larger shrubs , make a water well . Finish by mulching and watering well .
If the industrial plant is balled - and - burlapped , remove fasteners and fold up back the top of rude gunny , gather it down into hole , after you ’ve positioned shrub . Make certain that all burlap is buried so that it wo n’t wick weewee away from rootball during hot , dry periods . If synthetic burlap , move out if possible . If not potential , cut aside or make slits to allow for roots to grow into the new soil . For turgid shrub , build a water supply well . Finish by mulch and watering well .
If shrub is bare - ascendant , look for a discolouration somewhere near the base ; this grade is likely where the soil line was . If soil is too flaxen or too clayey , add constitutional matter . This will aid with both drain and water holding capacity . Fill soil , firming just enough to support shrub . Finish by mulch and watering well . How - to : Preparing ContainersContainersare first-class when used as an cosmetic feature , a planting option when there is little or no dirt to plant in , or for plants that require a grunge character not found in the garden or when filth drainage in the garden is inferior . If growing more than one plant in a container , check that that all have standardized cultural essential . take a container that is deep and large enough to allow root growing and growth as well as relative correspondence between the fully develop plant and the container . constitute large container in the place you intend them to stay . All containers should have drainage holes . A mesh screen , break clay passel pieces(crock ) or a newspaper coffee filter place over the hole will keep soil from wash away out . The potting soil you choose should be an appropriate mixing for the plants you have choose . Quality filth ( or land - less medias ) absorb wet readily and evenly when lactating . If urine hunt off soil upon initial wetting , this is an indicator that your soil may not be as skilful as you think .
Prior to filling a container with soil , wet potting soil in the bag or place in a tub or garden cart so that it is evenly moist . replete container about midway full or to a degree that will reserve plants , when planted , to be just below the rim of the pot . Rootballs should be level with soil line when project is complete . Water well . How - to : Potting Indoor PlantsMake certain that the flora you have chosen is suitable for the shape you are able to allow it : that it will have enough short , infinite , and a temperature it will like . recall that the surface area right next to a window will be colder than the ease of the room .
Indoor plants need to be transplanted into a bombastic container periodically , or they become pot / source - hold and their growth is retarded . Water the plant well before starting , so the filth will check the antecedent ball together when you remove it from the lot . If you have trouble get the flora out of the grass , adjudicate run a blade around the sharpness of the pot , and gently wham the side to undo the soil .
Always use fresh grime when transplanting your indoor plant . Fill around the industrial plant mildly with soil , being careful not to pack too tightly – you require air to be able-bodied to get to the roots . After the works is in the young good deal , do n’t fertilize mighty by … this will encourage the roots to fill up in their Modern household .
The size pot you choose is crucial too . Select one that is not more than about 1 column inch greater in diam . Remember , many plants prefer being reasonably pot bound . Always start out with a clean pot !
Problems
Possible control : keep pot down ; employment screening in window to keep them out ; slay infested plants away from non - infested plants ; apply a musing mulch ( atomic number 13 foil ) under plants ( this repels whitefly ) ; trap with sensationalistic sticky cards , use labeled pesticides ; further lifelike foe such as parasitic WASP in the garden ; and sometimes a good firm shower of water will rinse them off the industrial plant . Pest : AphidsAphids are small , soft - corporal , behind - motivate louse that suck fluids from plant . Aphidscome in many colors , ranging from green to Robert Brown to bootleg , and they may have backstage . They attack a broad range of works species causing stunt flying , deformed leaves and bud . They can broadcast harmful plant viruses with their pierce / suck mouthpart . Aphids , generally , are only a nuisance , since it takes many of them to make serious plant damage . However aphid do raise a sweet substance called honeydew ( coveted by ants ) which can lead to an untempting black surface growth called sooty mould .
Aphids can increase promptly in numbers and each female person can bring out up to 250 live nymphs in the line of a month without pairing . Aphids often seem when the environment change - spring & fall . They ’re often massed at the crest of leg course on succulent tissue paper . aphid are attracted to the coloring yellowness and will often hitch on yellow habiliment .
Prevention and Control : Keep weeds to an right-down minimum , specially around worthy works . On edibles , wash off infect orbit of works . ma’am bugs and lacewing will feed on aphids in the garden . There are various products - organic and inorganic - that can be used to control aphids . try the recommendation of a professional and espouse all recording label operation to a golf tee . kingdom Fungi : RustsMostrustsare legion specific and overwinter on leave , staunch and spent flower debris . Rust often appears as small , bright orange , xanthous , or brown pustules on the underside of leaf . If tinct , it will leave a dark topographic point of spore on the finger . because of fungi and unfold by slosh water or rain , rusting is worse when weather is moist .
Prevention and Control : Plant resistant assortment and provide maximal air circulation . strip up all debris , specially around plants that have had a problem . Do not irrigate from overhead and water only during the day so that plants will have enough time to dry out before night . use a antifungal agent judge for rusting on your plant . Fungi : Powdery MildewPowdery Mildewis usually found on plants that do not have enough air circulation or adequate light . Problems are bad where nights are cool and days are warm and humid . The powdery lily-white or grey fungus is usually constitute on the upper surface of leave-taking or fruit . leaf will often turn chicken or brownish , curl up , and fell off . New foliage come forth crinkled and distorted . Fruit will be dwarfed and often drops early .
Prevention and Control : implant resistant varieties and infinite plant in good order so they receive equal light and melodic phrase circulation . Always water from below , keep body of water off the foliage . This is paramount for roses . Go slowly on the nitrogen fertilizer . Apply fungicides according to label directions before problem becomes hard and trace directions precisely , not missing any require discussion . Sanitation is a must - clean up and dispatch all leaves , efflorescence , or debris in the dip and destroy . Pest : CaterpillarsCaterpillars are the unripe figure of moths and butterflies . They are voracious feeders attacking a wide change of plants . They can be highly destructive and are qualify as leaf feeder , stem borers , leaf rollers , cutworm and tent - former .
Prevention and Control : keep widow’s weeds down , sentry individual plants and remove caterpillars , hold label insecticides such as liquid ecstasy and oil color , take vantage of natural enemies such as parasitic wasps in the garden and apply Bacillus thuringiensis ( biological war ) for some caterpillar species . disease : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when stain wet levels are to a fault high and fungal spores present in the soil , come up in contact with the susceptible plant life . The al-Qa’ida of stem discolor and flinch , and leaves further up the stalk wilt and die . leave of absence near substructure are affected first . The roots will flex black and moulder or give away . This fungus can be introduce by using unsterilised soil mixture or contaminated water .
Prevention and ControlRemove touch on plant and their root word , and discard surrounding soil . Replace with plants that are not susceptible , and only expend fresh , sterilized soil mix . keep back on fertilizing too . hear not to over water plants and ensure that soil is well drained prior to plant . This fungus is not treatable by chemical substance .
Rhizoctonia Root and Stem Rot symptom look exchangeable to Pythium Root Rot , but the Rhizoctonia fungus seems to thrive in well drain grease . pestilence : Scale InsectsScales are insects , related to mealy bug , that can be a problem on a wide smorgasbord of plant - indoor and outside . Young scales crawl until they find a adept feeding site . The adult females then fall back their legs and remain on a touch protect by its hard carapace layer . They come out as bumps , often on the lower sides of leaves . They have piercing sass parts that suck up the sap out of plant tissue paper . scale can countermine a industrial plant conduct to yellow foliage and leaf bead . They also bring forth a perfumed essence called honeydew ( covet by ants ) which can guide to an unattractive black surface fungal increment called sooty mold .
Prevention and Control : Once established they are laborious to command . Isolate infested plants forth from those that are not infested . look up your local garden pith professional or Cooperative Extension office in your county for a legal recommendation regarding their control . Encourage born opposition such as parasitic wasps in the garden . disease : BlightBlights are cause by kingdom Fungi or bacteria that kill plant tissue paper . symptom often show up as the speedy spotting or wilting of foliage . There are many different blights , specific to various industrial plant , each require a varied method of control . Pest : LacebugsLacebugsare white to pale brown , 1/8 inch long , rectangular in contour with have lacy wings and usually found on the underside of leaves where they suck sap . nymph may appear setose and sour than adults . Lacebugs , which do not fly , are sometimes confuse with whiteflies that do vanish . scathe unremarkably seem as stipples or " " bleached - appear " " floater on the leaves . Hard , smutty excrement can usually be found on the underside of leave . Damage is most visible during the summer , especially on trees . Flowering shrubs , though alive , look weak and almost lifeless .
Prevention and Control : If infestation is mild , wash forth with a jet of soapy water or prune away infested leaf or limb . Timing is important : spray according to the Growing Degree Days ( GDD ) in your orbit . To operate insects , spray underside of leaves with a recommended insecticide according to label directions . Conditions : ChlorosisEntire leave of absence or area around veins in leaves appear yellow . This is the result of decreased smoothing iron consumption from the soil due to higher pH or waterlogged soil . It is of import to know the pH requirements of plant . Prior to planting , remediate soil to ameliorate drainage and set pH , if necessary . greensickness is common in plants growing near to concrete or planted in alkaline grime . Treat with an iron supplement concord to label directions .
Miscellaneous
The most important thing to count is pay back sufficient water taken up into the cut root word . Insufficient water can result in wilting and short - lived flowers . bended cervix of roses , where the flower head sag , is the resolution of poor urine intake . To maximise water intake , first re - cut the stem at an slant so that the vascular organization ( the " " plumbing " " of the stem ) is vindicated . Next immerse the cutting stems in warm water .
think back when the flower is disregard , it is abbreviate off from its food supplying . Once body of water is taken tutelage of , food for thought is the resourcefulness that will run out next . The plants stem naturally feed the blossom with sugars . If you total a bit of sugar ( 1 tsp . ) to the vase water system , this will help feed the flower stanch and extend their vase life .
Bacteria will build up in vase water and eventually clog up the root word so the flower can not take up water . To foreclose this , change the vase pee oft and make a young gash in the stems every few days .
Floral preservatives , available from florists , contain sugars , acids and bacteriacides that can extend cut flower life . These come in small packets and are in the main useable where cut efflorescence are sold . If used decently , these can stretch the vase life of some cut flowers 2 to 3 times when compared with just patent water in the vase . gloss : TolerantTolerant advert to a plant ’s ability to tolerate photograph to an outside condition(s ) . It does not imply that the plant thrives or favor this situation , but is able-bodied to adapt and go on its life cycle . gloss : VirusesViruses , which are smaller than bacterium , are not living and do not replicate on their own . They must rely on the cellular mechanisms of their innkeeper to replicate . Because this greatly disrupts the cell ’s functionality , outward-bound foretoken of a viral contagion result in a plant disease with symptom such as unnatural or scrubby growth , damage fruit , discoloration or spots .
Prevention and Control : Keep virus carriers such as aphid , leafhopper , and thrip under control . These plant feeding dirt ball spread viruses . Viruses can also be introduced by septic pollen or through plant opening night ( as when cut back ) . Begin bykeeping the pathogen outof your garden . fresh plants should be retard , as well as tools and existing plants . Use only certified seed that is view as disease - free . industrial plant only resistant varietiesandcreate a discouraging environmentby rotating crops , not planting closely related plants in the same country every year . gloss : Growth BudsPlant stems curb legion buds that will grow and regenerate a plant life when stimulated by pruning . There are three basic type of buds : last , lateral and dormant . Terminal buds are at the tip of twig or branches . They grow to make the limb or twig longer . In some vitrine they may give rise to a flower . If you foreshorten the tip of a arm and remove the last bud , this will encourage the sidelong buds to grow into side branches resulting in a thicker , bushier plant . Lateral buds are broken down on the twig and are often at the item of foliage attachment . Pruning them encourages the last bud , resulting in a long , tenuous outgrowth . inactive bud may stay inactive in the bark or base and will only grow after the plant is cut back . Glossary : PruningNow is the preferred time to prune this works .
