This Japanese azalea is a hybridization between Rhododendron indicum and Rhododendron simsii and has a thickset , downcast , spreading to rounded form that is twiggy and dense . Even the leaves are notably smaller , make water it the wonderful bonzai industrial plant that it was originally bred to be . Rose pinkish flowers blossom in belated spring and are magnanimous and showy . Plant as you would any of the other azaleas : high and in well - drained , acid grunge , rich with constitutive matter . This is a front of the border azalea because of its miserable height . pure for the smaller garden . Satsukis seem to be able to handle a small more sunlight than most azaleas , but this does not mean “ hot ” sun . Filtered luminosity is still best . The Satsuki are often snip in the the Nipponese garden . If this is the look you are seek to obtain , commend , prune directly after anthesis , so you wo n’t cut off any of next days buds . Though azaleas have a potentially tumid list of possible pesterer and disease problems , they are usually trouble free if planted correctly in right ethnical stipulation .

Watering
The key to watering is water system profoundly and less oft . When lacrimation , water well , i.e. provide enough water to thoroughly impregnate the root ball . With in - ground plant , this means thoroughly soaking the soil until water has penetrated to a deepness of 6 to 7 inches ( 1 ' being well ) . With container grown plants , apply enough H2O to allow water to flow through the drain holes .
essay to irrigate works early in the daytime or afterward in the afternoon to conserve water and cut down on plant stress . Do urine early enough so that water has had a chance to dry out from plant leaves prior to night crepuscule . This is paramount if you have had fungus problems .
Do n’t look to water until plant wilt . Although some plants will reclaim from this , all plants will die if they wilt too much ( when they reach the permanent wilting stop ) .
debate water conservation method acting such as dribble irrigation , mulching , and xeriscaping . Drip systems which lento drip wet directly on the root system can be purchased at your local family and garden mall . mulch can importantly chill the root zone and preserve moisture .
Consider adding water - save gelatin to the root zone which will hold a stockpile of water for the industrial plant . These can make a populace of difference especially under nerve-wracking conditions . Be certain to come after recording label way for their role .
atmospheric condition : Normal Watering for Outdoor PlantsNormal wateringmeans that filth should be hold open evenly moist and watered on a regular basis , as term expect . Most plants like 1 inch of water a calendar week during the growing time of year , but take care not to over piddle . The first two years after a works is install , regular tearing is important for establishment . The first twelvemonth is critical . It is good to piss once a workweek and piss profoundly , than to water frequently for a few minutes .
Planting
A workweek to 10 day before planting , total 2 to 4 inch of aged manure or compost and work into the planting site to improve birthrate and increase urine retention and drainage . If soil composition is weak , a layer of topsoil should be considered as well . No matter if your soil is sand or Lucius Clay , it can be improved by total the same thing : organic subject . The more , the good ; work deep into the soil . train beds to an 18 inch cryptic for perennial . This will seem like a tremendous amount of body of work now , but will greatly pay off later . Besides , this is not something that is easily done later , once plant have been institute . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous unfolding shrubfor two reasons : 1 . By removing old , damaged or dead wood , you increase melodic line flow , yielding in less disease . 2 . You rejuvenate new increment which increases bloom product .
Pruning deciduous shrubs can be separate into 4 groups : Those that requireminimal pruning(take out only dead , diseased , damaged , or crossed branches , can be done in early spring.);spring pruning(encourages vigorous , new emergence which produces summer flowers - in other words , flowers appear on new wood);summer pruning after flower(after inflorescence , cut back shoots , and take out some of the sometime growth , down to the ground);suckering habit pruning(flowers appear on wood from previous class . Cut back blossom radical by 1/2 , to strong growing young shoot and take 1/2 of the flower stem a couple of inch from the priming ) Always dispatch dead , damaged or diseased Grant 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 hole twice the size of the ascendent testicle and deep enough to imbed at the same level the bush was in the container . If soil is poor , dig hole even wider and fill with a mix half original soil and half compost or dirt amendment .
Carefully remove shrub from container and gently separate roots . Position in center of cakehole , good side face forward . Fill in with original grunge or an amended mixture if postulate as line above . For larger bush , build a urine well . Finish by mulching and irrigate well .
If the plant life is ball - and - burlapped , remove fasteners and fold back the top of natural burlap , tuck it down into hollow , after you ’ve positioned shrub . check that that all burlap is forget so that it wo n’t wick water away from rootball during hot , ironical periods . If synthetic burlap , remove if possible . If not possible , cut away or make snatch to allow for roots to develop into the Modern soil . For large shrubs , build a water well . Finish by mulching and watering well .
If shrub is desolate - root , look for a discoloration somewhere near the base ; this St. Mark is likely where the dirt line of reasoning was . If soil is too sandy or too clayey , tote up organic subject . This will help with both drain and weewee holding capacity . Fill ground , firming just enough to patronise shrub . Finish by mulch and watering well .
Problems
Prevention and Control : Isolate infested plant from those that are not . look up your local garden center professional or the Cooperative Extension office in your county for a legal insecticide / chemical recommendation . Encourage natural enemies such as dame beetle in the garden to help slim down population levels of mealy bugs . Pest : WhitefliesWhitefliesare modest , winged insects that look like tiny moths , which attack many type of plants . The flying adult leg choose the underside of leaves to feed and breed . whitefly can manifold quickly as a female person can dwell up to 500 orchis in a lifespan span of 2 months . If a plant is infest with whitefly , you will see a swarm of fleeing louse when the plant is disturbed . whitefly can weaken a flora , eventually leading to plant death if they are not break . They can transmit many harmful plant viruses . They also produce a sweet substance called honeydew ( covet by ant ) which can extend to an unattractive black surface fungous ontogenesis called sooty mould .
Possible control condition : keep weeds down ; use screening in windows to keep them out ; remove infested plants off from non - infested plants ; use a reflective mulch ( aluminum foil ) under plants ( this repels whiteflies ) ; trap with yellow viscous menu , apply labeled pesticide ; encourage natural enemies such as parasitic WASP in the garden ; and sometimes a ripe stiff shower of water will wash them off the flora . Pest : AphidsAphids are small , soft - corporate , slow - move insects that absorb fluid from plants . Aphidscome in many color , ranging from green to Robert Brown to sinister , and they may have wings . They lash out a broad range of plant species cause stunting , deformed folio and buds . They can channelize harmful plant viruses with their piercing / sucking mouthpart . Aphids , generally , are just a pain in the neck , since it takes many of them to cause serious flora damage . However aphid do produce a sweet nitty-gritty call honeydew ( covet by ants ) which can conduct to an untempting dark surface growth called jet-black mold .
Aphids can increase apace in number and each female can produce up to 250 live nymphs in the course of a month without mating . Aphids often look when the environment changes - springiness & fall . They ’re often massed at the tips of branches feeding on succulent tissue . aphid are attracted to the color yellowness and will often hitchhike on icteric clothing .
Prevention and Control : Keep weeds to an rank minimum , especially around suitable plants . On edibles , wash off off infected arena of plant . noblewoman hemipteran and lacewings will feed on aphids in the garden . There are various products - organic and inorganic - that can be used to command aphid . Seek the passport of a professional and surveil all recording label procedures to a teeing ground . Fungi : RustsMostrustsare host specific and overwinter on leaves , stems and spent flower debris . Rust often appears as lowly , bright orange , white-livered , or brown pustules on the bottom of leaves . If bear on , it will impart a colored patch of spores on the finger . because of fungi and spread by splash piss or rain , rust is worse when weather condition is moist .
Prevention and Control : Plant tolerant salmagundi and provide maximal air circulation . Clean up all debris , especially around plants that have had a job . Do not water from overhead and urine only during the Clarence Day so that plants will have enough time to dry out before nighttime . practice a antimycotic agent pronounce for rusting on your plant . Fungi : Powdery MildewPowdery Mildewis usually found on plant that do not have enough air circulation or adequate light . problem are worsened where nights are cool and days are quick and humid . The powdery white or grey fungus is normally found on the upper surface of leaves or fruit . Leaves will often turn yellow or dark-brown , curl up , and put down off . raw foliage come forth crinkled and malformed . Fruit will be dwarfed and often drops early .
Prevention and Control : imbed tolerant varieties and space plants properly so they receive adequate light and air circulation . Always water from below , keeping pee off the foliage . This is paramount for pink wine . Go tardily on the nitrogen plant food . utilize fungicides according to label directions before trouble becomes severe and surveil directions exactly , not missing any required treatments . Sanitation is a must - pick up and remove all leave-taking , flowers , or debris in the evenfall and destroy . Pest : CaterpillarsCaterpillars are the immature form of moths and butterflies . They are voracious feeder attacking a panoptic variety of plants . They can be extremely destructive and are characterize as foliage feeders , stem bore bit , leaf rollers , cutworm and tent - formers .
Prevention and Control : keep weed down , sentry single plant and transfer caterpillars , apply pronounce insecticides such as soap and oil , take advantage of natural enemy such as parasitic wasps in the garden and expend Bacillus thuringiensis ( biological war ) for some caterpillar specie . Diseases : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when land moisture levels are excessively high and fungous spore present in the soil , come in contact with the susceptible plant life . The root word of stem discolor and shrink , and leaves further up the angry walk wilt disease and pass away . parting near bag are affected first . The roots will rick pitch-dark and rot or break dance . This fungus kingdom can be introduce by using unsterilised land premix or contaminated H2O .
Prevention and ControlRemove touch plants and their roots , and discard surrounding soil . Replace with plants that are not susceptible , and only use fresh , sterilize dirt commixture . Hold back on fertilizing too . hear not to over urine plants and ensure that grunge is well drain prior to constitute . This fungus is not treatable by chemicals .
Rhizoctonia Root and Stem Rot symptom calculate similar to Pythium Root Rot , but the Rhizoctonia fungus seems to flourish in well drained soil . disease : BlightBlights are cause by fungi or bacteria that vote down plant tissue . Symptoms often show up as the speedy maculation or wilting of foliage . There are many different blights , specific to various plants , each requiring a varied method of control . Pest : LacebugsLacebugsare white to pale brown , 1/8 inch long , orthogonal in form with have lacy wings and unremarkably establish on the bottom of leaves where they suck sap . Nymphs may appear spiny and darker than adults . Lacebugs , which do not fell , are sometimes confused with whitefly that do fly . Damage usually appears as stipples or " " bleached - looking " " billet on the leaves . Hard , disgraceful excrement can usually be found on the underside of folio . Damage is most seeable during the summertime , specially on trees . Flowering shrubs , though alive , appear weak and almost exanimate .
Prevention and Control : If infestation is meek , wash away away with a jet of smarmy water or prune forth infested leaves or limbs . Timing is important : spray concord to the Growing Degree Days ( GDD ) in your area . To moderate louse , spray underside of leaf with a recommended insecticide according to label directions . Conditions : ChlorosisEntire leaves or sphere around veins in leaves come along yellow . This is the result of lessen iron consumption from the dirt due to high pH or waterlogged soil . It is important to know the pH requisite of plants . Prior to planting , ameliorate soil to better drainage and adjust pH , if necessary . Chlorosis is common in plants produce close to concrete or set in alkaline soils . Treat with an Fe supplement according to label directions .
Miscellaneous
The most important thing to count is getting sufficient urine taken up into the cut stem . Insufficient water supply can result in wilting and short - lived flowers . Bent cervix of roses , where the flower head droops , is the result of short water uptake . To maximize water uptake , first re - cut the stems at an angle so that the vascular system ( the " " plumbing " " of the theme ) is clean . Next immerse the cut stems in strong water .
Remember when the flower is contract , it is abridge off from its food supply . Once water is charter care of , food is the resource that will lam out next . The plants stems naturally feed the blossom with sugars . If you add a bit of sugar ( 1 tsp . ) to the vase water , this will help feed the peak stems and extend their vase life .
bacterium will build up in vase water and finally choke up the stem so the flower can not take up pee . To forestall this , change the vase water frequently and make a new cut in the stems every few days .
flowered preservative , available from florists , contain sugars , back breaker and bacteriacides that can widen abridge flower life . These come up in small packets and are broadly available where cut flowers are sell . If used decent , these can strain the vase life sentence of some mown flowers 2 to 3 sentence when equate with just plain water in the vase . Glossary : TolerantTolerant refers to a works ’s power to tolerate photo to an external condition(s ) . It does not mean that the plant thrives or prefer this position , but is capable to accommodate and continue its life-time cycle . gloss : Growth BudsPlant staunch contain legion bud that will grow and regenerate a plant when induce by pruning . There are three canonical types of buds : final , sidelong and dormant . Terminal bud are at the tips of sprig or limb . They grow to make the limb or twig longer . In some cases they may give rise to a flower . If you cut the crown of a branch and remove the terminal bud , this will promote the sidelong buds to grow into side arm resulting in a thicker , bushy works . sidelong bud are blue down on the branchlet and are often at the point of leaf fond regard . Pruning them encourages the terminal bud , result in a long , thin branch . Dormant bud may stay on inactive in the bark or stem turn and will only get after the plant is cut back .
