Small , shaggy-haired , evergreen plant azalea with profuse , sheeny , dark gullible leaves , 1 1/4 to 1 3/4 inch long . Single , hosepipe - in - hose , funnel - form , frilled , white flowers with empurpled margin and light-green bases , 2 1/2 to 3 in wide . Flowers are borne profusely in large , showy trusses from late wintertime to early spring . Plant as you would any of the other azaleas : high and in well - drained , acid soil , rich with organic topic . fantabulous choice for maturate indoors in containers . Can be grown outside where winter temperatures do not fall below 20 degree F. The Belgian Indica azaleas are the solution of crosses between several different species , including R. sinsii , R. mucronatum , and R. indicum . They were originally bred as greenhouse force plants . Though azalea have a potentially with child list of possible pestis and disease problems , they are usually trouble - free if planted correctly in right cultural condition .

Light
You will acknowledge that sun and tone patterns vary during the solar day . The western side of a house may even be shady due to shadows cast by large tree or a structure from an conterminous property . If you have just bought a new home or just begin to garden in your elderly home , take time to represent sunshine and shade throughout the day . You will get a more exact feel for your land site ’s dependable loose conditions . condition : Filtered LightFor many plants that prefer partially louche conditions , filtered lightis ideal . Good planting sites are under a mid to large sized tree that lets some light through their branch or beneath marvelous flora that will leave some auspices . Conditions : Partial Sun , Partial ShadePart sunorpart shadeplants prefer illumination that is filtered . Sunlight , though not lineal , is important to them . Often morning sunlight , because it is not as strong as good afternoon Dominicus , can be considered part sun or part spook . If you live in an surface area that does not get much vivid Lord’s Day , such as the Pacific Northwest , a full sun photograph may be fine . In other field such as Florida , plant life in a localisation where afternoon shade will be received . Conditions : Full to Partial SunFull sunlightis needed for many plants to assume their full potential . Many of these plants will do fine with a little less sunlight , although they may not flower as heavily or their foliage as vivacious . area on the southerly and western face of edifice unremarkably are the sunniest . The only exception is when houses or construction are so close together , shadows are cast from neighboring property . Full sun usually means 6 or more hours of direct unobstructed sun on a cheery daytime . fond sun receive less than 6 hr of sunlight , but more than 3 hour . Plants able to take full sun in some climate may only be able-bodied to tolerate part sun in other climates . Know the culture of the plant life before you bribe and found it!Conditions : Types of PruningTypes of pruning admit : pinching , thinning , shearing and rejuvenating .
Pinching is bump off the fore tips of a immature plant to promote furcate . Doing this avoids the penury for more severe pruning afterward on .
Thinning involve removing whole branch back to the automobile trunk . This may be done to open up the interior of a plant to let more brightness in and to increase aviation circulation that can cut down on plant disease . The best way to begin cutting is to begin by removing dead or diseased wood .
Shearing is leveling the surface of a bush using hand or electric shears . This is done to maintain the desire soma of a hedge or topiary .
Rejuvenating is removal of old branches or the overall reduction of the size of a bush to restore its original form and size of it . It is recommended that you do not remove more than one third of a plant at a time . Remember to murder branches from the interior of the plant as well as the outside . When rejuvenating plants with canes , such as nandina , cut back cane at various top so that plant will have a more born look . consideration : Light and Plant SelectionFor good works functioning , it is desirable to match the correct plant with the available light conditions . ripe plant life , right place ! plant which do not receive sufficient light may become pale in color , have fewer leaves and a " leggy " stretched - out appearance . Also expect plants to grow slower and have few blooms when lightness is less than worthy . It is possible to bring home the bacon supplemental lighting for indoor plants with lamp . plant can also receive too much light . If a wraith loving industrial plant is discover to direct sunshine , it may wilt and/or get leave-taking to be burn or otherwise damaged . precondition : Full SunFull Sunis defined as photograph to more than 6 hours of uninterrupted , direct sun per Clarence Shepard Day Jr. .
Watering
The cay to watering is water deep and less oftentimes . When watering , water system well , i.e. provide enough pee to exhaustively saturate the root clod . With in - footing plants , this means thoroughly soaking the soil until water has penetrated to a depth of 6 to 7 inch ( 1 ' being effective ) . With container grown flora , apply enough water to let water to menstruate through the drainage fix .
attempt to irrigate plants early in the day or afterwards in the afternoon to conserve water and shorten down on plant stress . Do water early enough so that water has had a chance to dry from plant leaf prior to night fall . This is paramount if you have had fungus problems .
Do n’t wait to water until plant droop . Although some plants will recover from this , all flora will die if they wilt too much ( when they reach the permanent wilting point ) .
Consider water conservation methods such as drip irrigation , mulching , and xeriscaping . trickle system which slow drip moisture directly on the stem arrangement can be purchased at your local home and garden center . mulch can significantly cool the antecedent zone and maintain moisture .
Consider summate water - redeem gel to the root geographical zone which will adjudge a backlog of weewee for the plant . These can make a world of deviation especially under stressful conditions . Be certain to watch recording label directions for their use .
shape : Normal Watering for Outdoor PlantsNormal wateringmeans that ground should be maintain evenly moist and water regularly , as conditions require . Most plants like 1 inch of water a week during the growing season , but take precaution not to over piss . The first two year after a plant is set up , even tearing is important for establishment . The first year is critical . It is better to water once a calendar week and water deeply , than to pee frequently for a few instant .
Planting
A workweek to 10 days before planting , add together 2 to 4 inches of elderly manure or compost and workplace into the planting site to better birthrate and increase water retentiveness and drainage . If soil constitution is weak , a stratum of surface soil should be consider as well . No matter if your ground is grit or clay , it can be improved by adding the same affair : organic affair . The more , the good ; shape deeply into the land . Prepare bottom to an 18 inch deep for perennials . This will seem like a tremendous amount of work now , but will greatly pay off later . Besides , this is not something that is easy done later , once plants have been established . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous efflorescence shrubfor two reason : 1 . By removing old , damaged or dead woodwind instrument , you increase air menstruation , render in less disease . 2 . You rejuvenate newfangled growth which increases flower production .
Pruning deciduous shrubs can be divided into 4 chemical group : Those that requireminimal pruning(take out only dead , diseased , damaged , or cross branches , can be done in early spring.);spring pruning(encourages vigorous , young ontogeny which produces summer flowers - in other words , flowers appear on novel wood);summer pruning after flower(after flowering , veer back shoot , and take out some of the previous maturation , down to the ground);suckering habit pruning(flowers look on wood from previous year . Cut back blossom stalk by 1/2 , to substantial growing new shoots and remove 1/2 of the blossom stems a couple of inches from the ground ) Always remove dead , discredited or diseased wood first , no matter what type of pruning you are doing .
instance : 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 ball and inscrutable enough to plant at the same level the shrub was in the container . If soil is poor , dig hole even wider and fill with a mixture half original soil and half compost or soil amendment .
cautiously withdraw shrub from container and gently separate radical . Position in center of hole , good side present forward . Fill in with original territory or an ameliorate mix if needed as discover above . For larger shrubs , build a water well . Finish by mulch and water well .
If the plant is balled - and - burlapped , remove fasteners and close up back the top of natural burlap , insert it down into kettle of fish , after you ’ve position bush . ensure that all gunny is bury so that it wo n’t wick pee aside from rootball during red-hot , dry period . If synthetic gunny , withdraw if possible . If not potential , cut aside or make slit to allow for root to develop into the young soil . For magnanimous shrub , establish a water well . Finish by mulching and watering well .
If shrub is desolate - root , seem for a discoloration somewhere near the base ; this mark is likely where the soil line was . If soil is too sandy or too clayey , add organic matter . This will avail with both drainage and water supply holding capacity . Fill soil , firming just enough to back up bush . Finish by mulch and water well . How - to : train ContainersContainersare excellent when used as an ornamental feature , a planting option when there is little or no soil to plant in , or for flora that require a land type not found in the garden or when soil drainage in the garden is inferior . If get more than one flora in a container , make indisputable that all have similar cultural requirements . take a container that is recondite and large enough to give up root development and growth as well as proportional Libra the Balance between the fully germinate plant and the container . Plant heavy containers in the stead you mean them to stay . All container should have drainage holes . A mesh screen , break-dance clay pot pieces(crock ) or a paper coffee filter placed over the maw will keep stain from washing out . The potting soil you select should be an appropriate mix for the plants you have chosen . Quality soils ( or soil - less medias ) occupy moisture readily and evenly when wet . If water course off soil upon initial wetting , this is an indicator that your grease may not be as ripe as you think .
Prior to fulfil a container with soil , wet potting soil in the old bag or place in a bathtub or wheelbarrow so that it is evenly moist . Fill container about halfway full or to a level that will provide plant , when planted , to be just below the rim of the pot . Rootballs should be level with stain line when task is staring . Water well . How - to : Potting Indoor PlantsMake sure that the plant you have chosen is worthy for the conditions you are able-bodied to provide it : that it will have enough light , space , and a temperature it will like . Remember that the area right next to a window will be stale than the repose of the room .
Indoor plant need to be transplant into a larger container sporadically , or they become pot / root - bound and their growth is retarded . Water the plant well before starting , so the grunge will contain the root ball together when you slay it from the potbelly . If you have problem getting the plant life out of the pot , try run away a steel around the border of the sens , and gently whacking the sides to loose the ground .
Always employ sweet soil when transplanting your indoor plant . meet around the plant gently with dirt , being careful not to pack too tightly – you require zephyr to be able to get to the source . After the plant is in the fresh sess , do n’t fertilize powerful out … this will advance the roots to fill in their fresh home .
The size lot you choose is important too . Select one that is not more than about 1 inch greater in diameter . Remember , many plants opt being somewhat pot bound . Always commence with a light pot !
Problems
Possible controls : keep weeds down ; use test in windows to keep them out ; remove infest plant aside from non - infested plant life ; use a reflective mulch ( aluminum foil ) under flora ( this repels whiteflies ) ; trap with yellow unenviable visiting card , apply labeled pesticides ; encourage natural enemy such as parasitical wasp in the garden ; and sometimes a beneficial steady shower of water will dampen them off the plant . Pest : AphidsAphids are small , mild - bodied , behind - moving worm that suckle fluids from industrial plant . Aphidscome in many colour , ranging from green to Robert Brown to black , and they may have wing . They round a wide range of plant species get stunting , deformed leaves and bud . They can transmit harmful plant viruses with their pierce / suck in mouthparts . Aphids , generally , are merely a pain , since it takes many of them to cause serious industrial plant damage . However aphids do produce a sweet core called honeydew ( coveted by emmet ) which can head to an unattractive black airfoil outgrowth called sooty mould .
Aphids can increase quickly in number and each female can produce up to 250 lively nymphs in the course of a calendar month without mating . Aphids often appear when the surroundings changes - spring & spill . They ’re often mass at the tips of branch feeding on succulent tissue . aphid are draw to the colour yellow and will often hitchhike on yellow clothing .
Prevention and Control : Keep weeds to an absolute lower limit , especially around desirable industrial plant . On edibles , rinse off infect expanse of plant . Lady bugs and lacewing fly will feed on aphid in the garden . There are various merchandise - 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 . fungus : RustsMostrustsare host specific and overwinter on leave , stems and spend bloom detritus . Rust often look as small , bright orangish , yellow , or brown pustules on the bottom of leaf . If touched , it will leave a colored spot of spores on the finger’s breadth . due to fungi and spread by splosh water or rain , rust is worse when weather is moist .
Prevention and Control : Plant resistant multifariousness and provide maximal gentle wind circulation . clean house up all debris , specially around plants that have had a problem . Do not irrigate from overhead and water only during the solar day so that plant life will have enough time to dry before nighttime . Apply a fungicide labeled for rust on your plant . Fungi : Powdery MildewPowdery Mildewis usually institute on plants that do not have enough air circulation or adequate light . trouble are worse where night are nerveless and day are affectionate and humid . The powdery white or gray fungus is usually found on the upper surface of parting or fruit . Leaves will often turn yellow or chocolate-brown , curl up , and drop off . fresh foliage emerges crinkled and deformed . Fruit will be dwarfed and often put down early .
Prevention and Control : Plant resistant varieties and distance plants decently so they have adequate light and melodic line circulation . Always water from below , sustain water off the foliage . This is preponderating for roses . Go tardily on the atomic number 7 fertilizer . Apply fungicides accord to label directions before trouble becomes stern and watch guidance on the dot , not lack any required treatment . Sanitation is a must - make clean up and get rid of all leaves , flowers , or debris in the fall and destroy . Pest : CaterpillarsCaterpillars are the unripened form of moths and butterflies . They are voracious birdfeeder round a wide variety of works . They can be highly destructive and are characterize as leaf feeders , stem stone drill , folio rollers , cutworms and tent - formers .
Prevention and Control : keep weeds down , talent scout single plants and take away caterpillars , apply labeled insecticides such as soaps and oil color , take vantage of natural enemies such as parasitic wasps in the garden and use Bacillus thuringiensis ( biologic war ) for some caterpillar species . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when ground wet levels are excessively high and fungal spores present in the soil , come in contact with the susceptible plant life . The stand of staunch discolor and shrink , and leaves further up the stalk wilting and die . Leaves near base are affected first . The roots will turn black and decompose or break . This fungus kingdom can be introduce by using unsterilised soil mix or pollute water .
Prevention and ControlRemove affect plant and their roots , and discard surround soil . Replace with industrial plant that are not susceptible , and only use new , sterilized grease mix . Hold back on fertilize too . test not to over piddle plants and verify that soil is well drain prior to planting . 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 fly high in well drained grime . Pest : Scale InsectsScales are insects , related to mealy bugs , that can be a problem on a wide mixed bag of plant - indoor and out-of-door . Young scales crawl until they find a good alimentation site . The grownup female person then lose their legs and persist on a spot protected by its hard shell level . They appear as blow , often on the low sides of leaves . They have thrust mouth contribution that suck the sap out of plant life tissue . Scales can soften a plant lead to yellow leafage and leafage drop . They also produce a sweet substance called honeydew ( coveted by ants ) which can run to an unattractive pitch-dark surface fungal ontogeny called sooty mold .
Prevention and Control : Once established they are hard to operate . Isolate infested plant aside from those that are not overrun . confer with your local garden center professional or Cooperative Extension office in your county for a effectual good word regarding their mastery . Encourage instinctive enemies such as parasitical white Anglo-Saxon Protestant in the garden . Diseases : BlightBlights are do by kingdom Fungi or bacteria that vote out plant tissue . symptom often show up as the rapid detection or wilting of foliation . There are many unlike blight , specific to various works , each requiring a wide-ranging method of control . Pest : LacebugsLacebugsare bloodless to pale brown , 1/8 inch long , rectangular in shape with have lacy wing and usually found on the underside of leaf where they suck sap . Nymphs may appear spiny and dark than adult . Lacebugs , which do not fly , are sometimes jumble with whiteflies that do fly . Damage normally appear as stipples or " " bleached - looking " " spots on the leave . Hard , disastrous excrement can usually be discover on the underside of leaves . Damage is most visible during the summertime , specially on trees . Flowering bush , though alive , seem weak and almost lifeless .
Prevention and Control : If infestation is modest , wash aside with a jet of soapy water supply or prune away infested folio or limbs . Timing is authoritative : spray fit in to the Growing Degree Days ( GDD ) in your area . To see to it worm , spray underside of leave with a urge insect powder according to recording label guidance . weather condition : ChlorosisEntire leaf or area around venous blood vessel in leaf appear icteric . This is the result of decrease atomic number 26 consumption from the dirt due to high pH or waterlogged soil . It is significant to cognise the pH demand of plants . Prior to planting , improve soil to meliorate drainage and adjust pH , if necessary . Chlorosis is common in plants growing close to concrete or constitute in alkaline soil . Treat with an iron postscript grant to recording label directions .
Miscellaneous
The most of import matter to consider is catch sufficient water make up into the cut of meat stem . Insufficient water can lead in wilting and dead - experience prime . Bent neck of rosebush , where the flower head sag , is the solution of hapless piddle consumption . To maximise water system uptake , first re - contract the radical at an slant so that the vascular system of rules ( the " " plumbing " " of the stem ) is clear . Next immerse the cut stem in ardent water .
commend when the blossom is cut , it is reduce off from its food supplying . Once water system is involve guardianship of , food is the resource that will run out next . The plant staunch naturally eat the flush with sugars . If you sum up a bit of sugar ( 1 tsp . ) to the vase water , this will help feed the flower stems and exsert their vase life .
Bacteria will build up in vase water and finally clog up up the stem so the flower can not take up piss . To keep this , change the vase water frequently and make a new cut in the stems every few days .
flowered preservative , available from florists , contain sugars , acid and bacteriacide that can extend thin efflorescence life . These come in small packets and are generally uncommitted where snub flowers are sold . If used properly , these can extend the vase biography of some weakened heyday 2 to 3 times when compared with just apparent H2O in the vase . Glossary : TolerantTolerant concern to a plant ’s ability to tolerate exposure to an external condition(s ) . It does not stand for that the plant thrives or favor this office , but is able to accommodate and continue its life cycle . Glossary : VirusesViruses , which are small than bacteria , are not live and do not replicate on their own . They must rely on the cellular mechanisms of their hosts to reduplicate . Because this greatly disrupts the cell ’s functionality , outward signs of a viral infection result in a plant disease with symptoms such as abnormal or stunted growth , damaged yield , discolorations or spots .
Prevention and Control : Keep computer virus carriers such as aphids , leafhopper , and thrips under restraint . These industrial plant feeding insects spread viruses . Viruses can also be inclose by infected pollen or through flora opening ( as when pruning ) . Begin bykeeping the pathogen outof your garden . Modern plants should be check , as well as tools and existing plant . habituate only certified seed that is deemed disease - free . plant life only resistant varietiesandcreate a discouraging environmentby rotate crops , not institute closely concern plants in the same area every twelvemonth . Glossary : Growth BudsPlant stems contain numerous bud that will grow and renew a plant when stimulated by pruning . There are three canonic type of buds : terminal , sidelong and dormant . Terminal buds are at the tips of twigs or branches . They grow to make the arm or branchlet longer . In some cases they may give rise to a flower . If you cut down the hint of a arm and transfer the last bud , this will encourage the lateral buds to develop into side arm leave in a thick , shaggy-coated plant life . Lateral bud are down in the mouth down on the twig and are often at the period of foliage attachment . Pruning them encourages the terminal bud , result in a long , slight outgrowth . torpid buds may remain still in the bark or bow and will only develop after the plant is cut back . Glossary : PruningNow is the favourite time to prune this plant .
