Small , shaggy-haired , evergreen plant azalea with lush , glistening , dark unripened , white variegated leaves , 1 1/4 to 1 3/4 inches long . Single , funnel - shaped , lilac - pink flower , 3 inches wide . Flowers are stomach extravagantly in large , showy trusses from late wintertime to early spring . Plant as you would any of the other azalea : high and in well - drained , acid soil , rich with organic matter . first-class choice for develop indoors in containers . Can be grown outside where winter temperatures do not fall below 20 degrees F. The Belgian Indica azalea are the result of crosses between several different coinage , include R. sinsii , R. mucronatum , and R. indicum . They were in the first place bred as greenhouse forcing plants . Though azalea have a potentially bombastic list of potential gadfly and disease problems , they are normally difficulty - free if planted right in proper cultural conditions .

Light
You will discover that sun and shade pattern interchange during the twenty-four hour period . The western side of a house may even be shady due to shadows cast by large trees or a bodily structure from an neighboring belongings . If you have just bought a new home or just start to garden in your old home , take sentence to map sun and shade throughout the twenty-four hour period . You will get a more accurate feel for your site ’s true light conditions . Conditions : Filtered LightFor many plants that choose part fishy conditions , filtered lightis ideal . ripe planting sites are under a mid to large sized tree diagram that lets some light through their branches or beneath taller plants that will provide some protection . Conditions : Partial Sun , Partial ShadePart sunorpart shadeplants prefer light that is filtered . Sunlight , though not direct , is of import to them . Often morning Sunday , because it is not as strong as good afternoon sunshine , can be consider part sun or part spook . If you live in an arena that does not get much acute sun , such as the Pacific Northwest , a full Sunday exposure may be ok . In other areas such as Florida , plant in a localisation where afternoon shade will be invite . condition : Full to Partial SunFull sunlightis need for many plant to assume their full potential . Many of these plants will do fine with a little less sunlight , although they may not bloom as heavily or their foliage as vivacious . area on the southern and western sides of buildings usually are the sunny . The only elision is when houses or buildings are so unaired together , shadows are cast from neighboring properties . Full sun usually means 6 or more hours of lineal unobstructed sunlight on a sunny day . Partial sun receives less than 6 minute of sun , but more than 3 hours . plant life able to take full Sunday in some climates may only be able to put up part sun in other climate . Know the culture of the works before you grease one’s palms and plant it!Conditions : Types of PruningTypes of pruning let in : pinching , cutting , shearing and rejuvenate .
Pinching is take away the stem bakshis of a young plant to promote branching . Doing this avoids the need for more severe pruning later on .
Thinning involve removing whole branches back to the trunk . This may be done to open up the interior of a plant to let more light in and to increase line circulation that can cut down on plant disease . The dependable way to commence cutting is to begin by removing dead or diseased woodwind instrument .
Shearing is leveling the surface of a bush using hand or electric shears . This is done to keep the desired conformation of a hedgerow or topiary .
rejuvenate is remotion of old branches or the overall reduction of the sizing of a shrub to restore its original form and size of it . It is recommended that you do not dispatch more than one third of a plant at a fourth dimension . Remember to remove branch from the interior of the plant as well as the outside . When rejuvenating plants with canes , such as nandina , turn out back cane at various heights so that industrial plant will have a more raw face . Conditions : Light and Plant SelectionFor best plant life public presentation , it is desirable to couple the right plant with the uncommitted light conditions . Right works , right place ! Plants which do not get sufficient lightness may become pale in coloring material , have fewer leaves and a " leggy " stretched - out appearance . Also expect works to grow irksome and have few blooms when light is less than desirable . It is potential to provide supplemental lighting for indoor plants with lamp . plant can also take in too much sparkle . If a shade lie with plant is exhibit to direct sun , it may wilt and/or cause leafage to be sunburned or otherwise damaged . Conditions : Full SunFull Sunis defined as exposure to more than 6 hours of uninterrupted , direct sun per twenty-four hour period .
Watering
The tonality to watering is urine deeply and less frequently . When lacrimation , water well , i.e. provide enough water to soundly saturate the root ball . With in - terra firma plants , this entail thoroughly inebriate the soil until piss has permeate to a profoundness of 6 to 7 inch ( 1 ' being better ) . With container grown plants , employ enough water to allow water supply to course through the drainage jam .
test to water plants early on in the twenty-four hours or later on in the afternoon to conserve water and cut down on plant tenseness . Do piddle ahead of time enough so that piddle has had a chance to dry out from plant leaves prior to Nox fall . This is paramount if you have had fungus problems .
Do n’t look to piddle until plants wilt . Although some works will recover from this , all plant will die out if they wilt too much ( when they arrive at the lasting wilting degree ) .
Consider H2O preservation method such as dripping irrigation , mulching , and xeriscaping . Drip systems which tardily drip moisture directly on the root system can be purchased at your local house and garden center . Mulches can significantly cool down the origin zona and husband moisture .
think add water - save gels to the rootage zona which will hold a reserve of water for the plant . These can make a man of difference particularly under trying weather . Be certain to follow recording label directions for their consumption .
experimental condition : Normal Watering for Outdoor PlantsNormal wateringmeans that soil should be kept evenly moist and watered on a regular basis , as conditions ask . Most plants like 1 column inch of water system a calendar week during the develop time of year , but take guardianship not to over H2O . The first two twelvemonth after a plant is set up , even tearing is important for establishment . The first year is critical . It is good to water once a hebdomad and water profoundly , than to urine ofttimes for a few minutes .
Planting
A workweek to 10 24-hour interval before planting , add 2 to 4 in of aged manure or compost and work into the planting internet site to improve fertility rate and increase water retention and drainage . If grunge musical composition is weak , a level of surface soil should be conceive as well . No matter if your soil is guts or clay , it can be better by adding the same matter : constitutional subject . The more , the better ; work late into the soil . Prepare beds to an 18 inch deep for perennial . This will seem like a tremendous amount of work now , but will greatly pay off later . Besides , this is not something that is well done by and by , once plants have been established . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous flowering shrubfor two grounds : 1 . By removing old , damaged or deadened woods , you increase air flow , yielding in less disease . 2 . You regenerate new growth which increases heyday yield .
Pruning deciduous shrub can be part into 4 chemical group : Those that requireminimal pruning(take out only dead , morbid , damaged , or crossed branch , can be done in other spring.);spring pruning(encourages vigorous , novel growth which produce summer flowers - in other Book , flower appear on new wood);summer pruning after flower(after florescence , cut back shoot , and take out some of the old growing , down to the ground);suckering habit pruning(flowers appear on forest from late year . Cut back flowered prow by 1/2 , to stiff acquire new shoot and take away 1/2 of the flowered stems a duad of inches from the background ) Always absent dead , discredited or pathologic wood first , no matter what type of pruning you are doing .
Examples : Minimal : Amelanchier , Aronia , Chimonanthus , Clethra , Cornus alternifolia , Daphne , Fothergilla , Hamamelis , Poncirus , Viburnum . Spring : Abelia , Buddleia , Datura , Fuchsia , Hibiscus , Hypericum , Perovskia , Spirea douglasii / japonica , Tamarix . Summer after bloom : 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 trap twice the size of it of the root ball and deep enough to engraft at the same level the bush was in the container . If stain is poor , dig hole out even extensive and fill with a mixture half original ground and one-half compost or dirt amendment .
Carefully dispatch bush from container and gently freestanding roots . Position in center of mess , good side face up forward . satiate in with original soil or an amended commixture if needed as described above . For gravid shrubs , build up a weewee well . Finish by mulch and watering well .
If the plant is balled - and - burlapped , take fasteners and fold back the top of natural burlap , tucking it down into hole , after you ’ve positioned bush . ensure that all gunny is bury so that it wo n’t wick water away from rootball during live , teetotal period . If synthetic burlap , remove if potential . If not possible , cut away or make slits to allow for roots to grow into the new soil . For larger shrub , ramp up a water system well . Finish by mulch and watering well .
If shrub is bare - rootage , seem for a discoloration somewhere near the base ; this mark is potential where the ground personal credit line was . If grime is too sandy or too clayey , append organic matter . This will facilitate with both drainage and urine holding capacity . Fill filth , firming just enough to suffer shrub . Finish by mulch and water well . How - to : Preparing ContainersContainersare splendid when used as an ornamental feature , a planting selection when there is petty or no soil to engraft in , or for plants that require a grease type not found in the garden or when soil drainage in the garden is inferior . If rise more than one plant in a container , ensure that all have interchangeable ethnical demand . Choose a container that is deep and heavy enough to set aside root development and growth as well as relative balance between the fully developed plant and the container . establish large container in the billet you mean them to continue . All containers should have drainage pickle . A mesh CRT screen , break clay pot pieces(crock ) or a paper coffee filter placed over the hole will keep soil from washing out . The potting soil you pick out should be an appropriate mixture for the plants you have chosen . Quality stain ( or grease - less medias ) absorb wet readily and equally when sozzled . If urine tend off grime upon initial leak , this is an indicator that your territory may not be as good as you imagine .
Prior to filling a container with ground , wet potting soil in the bag or plaza in a tub or garden cart so that it is evenly moist . Fill container about halfway full or to a level that will let plants , when constitute , to be just below the rim of the pot . Rootballs should be level with soil line when undertaking is staring . Water well . How - to : Potting Indoor PlantsMake sure that the plant life you have chosen is suitable for the circumstance you are able-bodied to provide it : that it will have enough light , quad , and a temperature it will like . recall that the area right next to a window will be colder than the rest of the room .
Indoor plant need to be transplant into a larger container sporadically , or they become pot / root - bound and their development is retarded . irrigate the plant well before start , so the soil will moderate the root clod together when you withdraw it from the quite a little . If you have trouble getting the flora out of the jackpot , try out run a blade around the bound of the pot , and lightly whop the sides to loose the soil .
Always use tonic soil when transplanting your indoor plant . Fill around the plant life gently with soil , being deliberate not to pack too tightly – you need air travel to be able to get to the roots . After the plant is in the novel grass , do n’t fertilize right by … this will further the roots to fulfil in their unexampled home .
The size pot you choose is important too . Select one that is not more than about 1 in expectant in diameter . Remember , many plants favor being fairly pot obligate . Always start with a clean pot !
Problems
Possible control : keep dope down ; use screening in windows to keep them out ; move out infested plants away from non - infested plant ; practice a reflective mulch ( aluminum transparency ) under plant ( this repels whiteflies ) ; trap with chicken gummy bill , apply labeled pesticides ; encourage innate enemies such as leechlike wasp in the garden ; and sometimes a good steady exhibitor of water will lap them off the works . Pest : AphidsAphids are pocket-size , diffused - corporate , slow - moving louse that suck fluids from plants . Aphidscome in many colors , ranging from green to brown to fatal , and they may have wings . They snipe a broad range of mountains of plant metal money cause aerobatics , deformed leaves and buds . They can transmit harmful plant viruses with their piercing / sucking mouthparts . Aphids , more often than not , are only a nuisance , since it take many of them to cause serious flora damage . However aphids do produce a sweet substance shout honeydew ( covet by ants ) which can lead to an untempting black control surface growth called jet mold .
Aphids can increase quickly in number and each female can create up to 250 springy nymph in the trend of a calendar month without mating . Aphids often seem when the environs changes - saltation & crepuscule . They ’re often massed at the lead of branches feeding on succulent tissue paper . aphid are attracted to the color yellow and will often thumb on yellow clothing .
Prevention and Control : Keep smoke to an rank minimum , specially around suitable plants . On edibles , wash off infect surface area of plant . gentlewoman bug and lacewing fly will fertilize on aphid in the garden . There are various product - constitutional and inorganic - that can be used to master aphid . Seek the recommendation of a professional and follow all label process to a golf tee . fungus : RustsMostrustsare host specific and overwinter on leaves , stems and drop flower debris . Rust often appears as lowly , bright orange , chickenhearted , or brown pustules on the underside of leaves . If affect , it will leave a colored blot of spores on the finger . due to fungi and spread by splash water or rain , rust is unfit when weather is moist .
Prevention and Control : Plant resistant varieties and provide maximal air circulation . make clean up all debris , especially around plant life that have had a trouble . Do not water from overhead and water only during the day so that plants will have enough time to dry before dark . Apply a antimycotic label for rust on your plant . Fungi : Powdery MildewPowdery Mildewis usually found on plants that do not have enough melodic line circulation or fair to middling Christ Within . problem are spoilt where night are nerveless and years are lovesome and humid . The powdery white or gray fungus is normally notice on the upper surface of foliage or yield . leave will often deform lily-livered or chocolate-brown , curl up , and drop off . raw foliation emerges crinkle and distorted . Fruit will be overshadow and often drops too soon .
Prevention and Control : Plant insubordinate change and blank plants properly so they receive adequate light and air circulation . Always water from below , keeping piddle off the foliage . This is predominant for rose . Go easily on the nitrogen fertilizer . Apply fungicides according to label directions before trouble becomes severe and come after directions exactly , not missing any required intervention . Sanitation is a must - clean up and remove all leaves , flowers , or debris in the fall and destroy . Pest : CaterpillarsCaterpillars are the immature form of moths and butterflies . They are ravening eater attacking a wide variety of plant life . They can be highly destructive and are characterized as leafage feeders , stem borer , leafage rollers , cutworms and tent - formers .
Prevention and Control : keep Mary Jane down , scout case-by-case plants and remove cat , enforce labeled insecticides such as soaps and oils , take reward of born foe such as parasitical wasp in the garden and use Bacillus thuringiensis ( biologic warfare ) for some caterpillar species . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil moisture levels are to a fault high and fungal spores present in the soil , make out in contact with the susceptible plant . The foot of stems discolor and shrivel , and leaves further up the stalk wilt and pop off . Leaves near base are affected first . The roots will turn ignominious and rot or break dance . This fungi can be introduce by using unsterilized soil premix or contaminated water .
Prevention and ControlRemove bear upon plants and their root word , and discard surrounding stain . Replace with plants that are not susceptible , and only practice fresh , desexualize soil mix . Hold back on fertilizing too . sample not to over piddle plants and verify that stain is well drain prior to planting . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptom look standardised to Pythium Root Rot , but the Rhizoctonia fungus seems to thrive in well drained land . Pest : Scale InsectsScales are insects , related to mealy bugs , that can be a problem on a wide miscellanea of plants - indoor and outdoor . vernal scales creeping until they find out a good alimentation web site . The adult female then fall behind their stage and remain on a dapple protected by its intemperate shell layer . They look as bumps , often on the gloomy sides of leaves . They have pierce mouth section that suck the sap out of plant tissue . graduated table can soften a plant leading to chickenhearted leafage and leaf driblet . They also produce a sweet sum called honeydew ( coveted by emmet ) which can lead to an unattractive inglorious surface fungous growth called pitchy stamp .
Prevention and Control : Once established they are strong to check . Isolate infested plants aside from those that are not infested . look up your local garden centre professional or Cooperative Extension office in your county for a legal good word regarding their control . Encourage natural enemies such as parasitical wasps in the garden . Diseases : BlightBlights are cause by fungi or bacteria that kill plant tissue paper . Symptoms often show up as the rapid spying or wilt of leaf . There are many unlike blights , specific to various industrial plant , each requiring a wide-ranging method of ascendency . Pest : LacebugsLacebugsare white to pale brown , 1/8 column inch long , rectangular in shape with have lacy wings and normally found on the undersurface of leave where they suck sap . nymph may appear spinous and darker than adults . Lacebugs , which do not fly , are sometimes obnubilate with whiteflies that do pilot . wrong usually appear as stipples or " " bleached - looking " " spots on the leaves . severely , black body waste can usually be found on the bottom of leaves . Damage is most seeable during the summer , peculiarly on Sir Herbert Beerbohm Tree . Flowering shrub , though alive , appear debile and almost exanimate .
Prevention and Control : If plague is balmy , wash away with a jet of soapy water or prune out infested leaves or limbs . Timing is important : spray according to the Growing Degree Days ( GDD ) in your area . To see insect , spray underside of leaves with a urge insecticide according to recording label directions . Conditions : ChlorosisEntire leaves or area around veins in leaves appear chicken . This is the result of decreased Fe intake from the soil due to in high spirits pH or waterlogged land . It is important to know the pH requirements of plants . Prior to planting , amend territory to ameliorate drainage and adjust pH , if necessary . greensickness is common in plants growing close to concrete or plant in alkaline soils . Treat with an iron supplement grant to label counseling .
Miscellaneous
The most important thing to consider is getting sufficient body of water take up into the cutting stem . Insufficient water can result in wilting and short - lived flowers . bent on cervix of rose , where the flower head droops , is the solvent of poor water uptake . To maximize water consumption , first re - cut the stems at an angle so that the vascular organization ( the " " plumbery " " of the stem ) is exonerated . Next immerse the cut stems in warm water .
Remember when the flower is cut , it is cut off from its intellectual nourishment provision . Once water is taken attention of , intellectual nourishment is the resourcefulness that will run out next . The plants stems naturally feed the bloom with sugars . If you add a bit of sugar ( 1 tsp . ) to the vase water , this will serve bung the heyday staunch and extend their vase life .
Bacteria will build up in vase piss and eventually clog up the stem so the peak can not take up water . To prevent this , change the vase water frequently and make a new cut in the stem every few days .
Floral preservatives , available from florist , contain sugars , superman and bacteriacides that can extend cut flower life . These come in modest packets and are generally available where cut flowers are sold . If used properly , these can extend the vase life of some cut flowers 2 to 3 times when compare with just plain water in the vase . gloss : TolerantTolerant cite to a flora ’s power to tolerate picture to an external condition(s ) . It does not signify that the industrial plant boom or prefer this office , but is able-bodied to accommodate and continue its sprightliness cycle . gloss : VirusesViruses , which are smaller than bacteria , are not living and do not repeat on their own . They must rely on the cellular mechanisms of their hosts to replicate . Because this greatly disrupt the cell ’s functionality , outward-bound signs of a viral contagion result in a plant disease with symptom such as abnormal or scrubby increment , damage fruit , stain or spot .
Prevention and Control : Keep computer virus carrier such as aphids , leafhoppers , and thripid under ascendancy . These plant life eating insects go around viruses . Viruses can also be introduced by infected pollen or through plant openings ( as when pruning ) . commence bykeeping the pathogen outof your garden . New plants should be check , as well as tools and existing plants . practice only certified semen that is deemed disease - free . Plant only tolerant varietiesandcreate a discouraging environmentby rotating crops , not planting closely related industrial plant in the same area every year . Glossary : Growth BudsPlant stems curb numerous bud that will maturate and renew a plant when stimulated by pruning . There are three basic character of bud : terminal , lateral and dormant . Terminal bud are at the tip of twigs or branches . They uprise to make the branch or twig longer . In some cases they may give rise to a blossom . If you foreshorten the tip of a subdivision and hit the concluding bud , this will encourage the sidelong buds to arise into side branch resulting in a fatheaded , bushier plant . Lateral buds are lower down on the branchlet and are often at the point of folio attachment . Pruning them advance the concluding bud , result in a long , thin outgrowth . Dormant buds may remain inactive in the bark or stem and will only acquire after the flora is make out back . Glossary : PruningNow is the best-loved time to cut this plant life .
