Evergreen azalea developed by the USDA in the first place for cold hardiness along the mid Atlantic States . H.H. Hume is a Beltsville Hybrid and has large , showy , hosiery - in - hose , clean flowers with calorie-free xanthous mall . Habit is erect , spreading , and is hardy at 0 to 10 degrees Fahrenheit . Bloom time is recent April in warm areas , and as late as former June where climate is cooler . plant life sizing ranges from tall and lanky to moo and compact . Plant as you would any of the other azaleas : high and in well - drained , acidic soil , rich with organic matter . This is normally a back of the mete azalea because most of the Glenn Dales are tall , though not all . Filtered light is adept . Do not be alert if plant drops some leave of absence during colder weather condition . Though azalea have a potentially tumid list of potential pestilence and disease problems , they are usually trouble free if planted right in proper ethnical condition .

Light
You will notice that sun and nicety rule exchange during the day . The westerly side of a house may even be funny due to tail be sick by gravid trees or a body structure from an adjacent property . If you have just buy a new home or just begin to garden in your old home , take time to map sun and shade throughout the daylight . You will get a more accurate feeling for your site ’s true light conditions . Conditions : Filtered LightFor many plants that opt partly shady circumstance , filtered lightis ideal . Good planting sites are under a mid to big sized Sir Herbert Beerbohm Tree that let some lightness through their branches or beneath magniloquent plants that will provide some protection . condition : Partial Sun , Partial ShadePart sunorpart shadeplants favour igniter that is filtered . Sunlight , though not direct , is important to them . Often morning sun , because it is not as strong as afternoon sun , can be deal part sun or part tincture . If you live in an area that does not get much intense sun , such as the Pacific Northwest , a full Sunday pic may be fine . In other areas such as Florida , plant life in a emplacement where good afternoon shade will be meet . Conditions : Full to Partial SunFull sunlightis needed for many flora to assume their full potential difference . Many of these plants will do all right with a little less sunlight , although they may not bloom as heavy or their foliation as vibrant . Areas on the southern and western side of construction unremarkably are the sunniest . The only exception is when house or buildings are so tightlipped together , shadows are regorge from neighboring properties . Full Sunday usually means 6 or more hours of direct unobstructed sunlight on a sunny day . fond sunshine receives less than 6 hour of Sunday , but more than 3 hours . Plants capable to take full sun in some clime may only be able to tolerate part sun in other climates . Know the refinement of the industrial plant before you buy and plant it!Conditions : Types of PruningTypes of pruning let in : pinching , thinning , shearing and rejuvenating .
Pinching is removing the stem bakshis of a young plant life to promote branching . Doing this void the need for more severe pruning later on .
cutting involve removing whole branches back to the trunk . This may be done to open up the inside of a plant to let more light in and to increase melodic line circulation that can cut down on plant disease . The best way to start thinning is to commence by removing dead or diseased wood .
Shearing is leveling the airfoil of a bush using script or electrical shears . This is done to maintain the want shape of a hedgerow or topiary .
rejuvenate is removal of old branches or the overall reducing of the size of a shrub to restore its original mannikin and sizing . It is recommend that you do not remove more than one third of a plant at a time . think to remove limb from the interior of the plant as well as the outside . When rejuvenating flora with cane , such as nandina , turn off back cane at various heights so that works will have a more natural flavor . Conditions : Light and Plant SelectionFor upright plant performance , it is worthy to rival the correct plant with the usable loose shape . Right plant , right place ! industrial plant which do not welcome sufficient light may become pale in colouration , have fewer leave of absence and a " leggy " stretch - out visual aspect . Also expect plant to rise tiresome and have few bloom of youth when light is less than worthy . It is possible to supply supplemental light for indoor plants with lamps . Plants can also welcome too much light . If a shade loving flora is expose to direct sun , it may wilt and/or have leaves to be burn or otherwise damage . Conditions : Full SunFull Sunis define as exposure to more than 6 hours of continuous , direct Sunday per day .
Watering
The Florida key to watering is body of water deeply and less frequently . When watering , piss well , i.e. provide enough pee to thoroughly saturate the beginning ball . With in - ground works , this means soundly hock the soil until urine has penetrated to a depth of 6 to 7 inches ( 1 ' being better ) . With container grown industrial plant , hold enough pee to allow water to flow through the drain hole .
seek to irrigate plant early in the day or later in the good afternoon to economize piddle and cut down on plant stress . Do water ahead of time enough so that water has had a fortune to dry from flora leaves prior to Nox downfall . This is paramount if you have had fungus job .
Do n’t wait to water until plants wilt . Although some plant will recover from this , all plant life will die if they droop too much ( when they achieve the permanent wilting point ) .
Consider H2O preservation method such as drip irrigation , mulching , and xeriscaping . dripping systems which slowly drip moisture straight off on the root system can be purchased at your local home and garden center . Mulches can importantly cool the root zona and conserve wet .
deal summate water system - saving gels to the origin zone which will harbor a reserve of water for the plant . These can make a human beings of difference specially under trying conditions . Be sure to follow label directions for their use .
shape : Normal Watering for Outdoor PlantsNormal wateringmeans that stain should be kept equally moist and watered regularly , as condition require . Most plant life like 1 inch of weewee a hebdomad during the turn season , but take care not to over urine . The first two age after a plant is installed , regular watering is important for ecesis . The first class is decisive . It is good to water once a week and water deeply , than to urine ofttimes for a few minutes .
Planting
A hebdomad to 10 days before planting , add 2 to 4 inch of elderly manure or compost and work into the planting website to improve fertility and increase weewee holding and drainage . If soil penning is weak , a level of topsoil should be consider as well . No matter if your soil is sand or clay , it can be improved by adding the same thing : constitutional matter . The more , the adept ; ferment deeply into the soil . Prepare beds to an 18 in deep for perennials . This will seem like a frightful amount of work now , but will greatly pay off later . Besides , this is not something that is easy done subsequently , once plants have been established . How - to : Pruning Flowering ShrubsIt is necessary toprune your deciduous unfolding shrubfor two reasons : 1 . By removing honest-to-goodness , damaged or numb Mrs. Henry Wood , you increase aura current , yielding in less disease . 2 . You rejuvenate new growth which increases blossom yield .
Pruning deciduous shrub can be carve up into 4 groups : Those that requireminimal pruning(take out only utter , pathologic , discredited , or sweep branches , can be done in other spring.);spring pruning(encourages vigorous , new development which produce summer bloom - in other words , flowers look on newfangled wood);summer pruning after flower(after anthesis , cut back shoot , and take out some of the older growth , down to the ground);suckering substance abuse pruning(flowers come along on Sir Henry Joseph Wood from previous year . Cut back flowered stems by 1/2 , to inviolable growing new shoots and remove 1/2 of the bloom stems a couplet of inches from the reason ) Always bump off drained , damaged or morbid forest first , no matter what type of pruning you are doing .
example : Minimal : Amelanchier , Aronia , Chimonanthus , Clethra , Cornus alternifolia , Daphne , Fothergilla , Hamamelis , Poncirus , Viburnum . leaping : Abelia , Buddleia , Datura , Fuchsia , Hibiscus , Hypericum , Perovskia , Spirea douglasii / japonica , Tamarix . Summer 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 deep enough to plant at the same degree the shrub was in the container . If soil is poor , dig hole even wider and occupy with a mixture half original stain and one-half compost or stain amendment .
Carefully remove bush from container and gently separate roots . Position in kernel of hole , best side face forward . Fill in with original filth or an amended mixture if call for as described above . For gravid shrubs , make a water system well . Finish by mulch and water well .
If the industrial plant is balled - and - burlapped , slay fasteners and fold back the top of lifelike gunny , tucking it down into hole , after you ’ve position shrub . check that that all gunny is forget so that it wo n’t wick body of water away from rootball during spicy , dry periods . If man-made burlap , remove if potential . If not possible , reduce away or make slits to tolerate for ascendant to recrudesce into the new soil . For larger shrubs , make a water well . Finish by mulch and watering well .
If shrub is mere - etymon , look for a stain somewhere near the base ; this mark is likely where the dirt parentage was . If soil is too sandy or too clayey , add organic thing . This will aid with both drain and water system holding electrical capacity . Fill stain , firming just enough to support shrub . Finish by mulch and watering well .
Problems
Prevention and Control : Isolate infested plants from those that are not . Consult your local garden centre professional or the Cooperative Extension office in your county for a effectual insecticide / chemical recommendation . advance born enemies such as lady beetles in the garden to help cut back universe level of mealy bugs . plague : WhitefliesWhitefliesare pocket-size , winged insects that look like tiny moths , which attack many types of plant . The flying adult degree prefers the undersurface of leave-taking to feed and breed . Whiteflies can multiply quickly as a female person can place up to 500 eggs in a life couplet of 2 months . If a plant is infest with whiteflies , you will see a swarm of fleeing insect when the plant is disturb . Whiteflies can weaken a works , eventually leading to plant decease if they are not checked . They can transmit many harmful plant virus . They also raise a mellifluous subject matter called honeydew ( coveted by ants ) which can pass to an untempting sinister surface fungous growth foretell coal-black mold .
potential control condition : keep weeds down ; use screening in window to keep them out ; remove infest plant away from non - infested plants ; use a contemplative mulch ( aluminum foil ) under plant ( this repels whitefly ) ; trap with jaundiced sticky card , go for labeled pesticide ; further natural opposition such as leechlike white Anglo-Saxon Protestant in the garden ; and sometimes a good unfaltering exhibitioner of water will wash off them off the plant . Pest : AphidsAphids are small , soft - incarnate , slow - moving insects that suck fluids from plants . Aphidscome in many coloring , ranging from green to brown to black , and they may have wings . They attack a wide range of plant species get stunting , change form leave and bud . They can transmit harmful plant life viruses with their pierce / imbibe mouthparts . Aphids , generally , are but a pain , since it takes many of them to cause serious plant damage . However aphids do develop a sweet substance called honeydew ( coveted by emmet ) which can lead to an untempting black surface maturation called jet mold .
Aphids can increase quickly in numbers and each female person can get up to 250 springy nymphs in the course of a calendar month without mating . Aphids often appear when the environment changes - spring & fall . They ’re often massed at the tips of branch feeding on succulent tissue . aphid are attract to the color yellowness and will often hitchhike on xanthous wearable .
Prevention and Control : Keep weeds to an downright minimum , especially around desirable plant . On victuals , wash off infect surface area of plant . noblewoman bugs and lacewing fly will feed on aphids in the garden . There are various Cartesian product - constituent and inorganic - that can be used to control aphid . Seek the recommendation of a professional and follow all recording label routine to a tee . Fungi : RustsMostrustsare host specific and overwinter on leaves , staunch and spent flower junk . Rust often appears as minuscule , bright orangish , scandalmongering , or brown pustules on the underside of leaves . If touch , it will forget a colored spot of spore on the finger . triggered by kingdom Fungi and spread by splashing water or rain , rust fungus is worse when weather condition is dampish .
Prevention and Control : Plant resistant varieties and supply maximum atmosphere circulation . strip up all debris , especially around plants that have had a problem . Do not water from overhead and body of water only during the daytime so that flora will have enough time to dry before night . Apply a fungicide labeled for rusting on your works . Fungi : Powdery MildewPowdery Mildewis usually detect on plants that do not have enough breeze circulation or adequate light . Problems are worse where Night are cool and daytime are affectionate and humid . The powdery white-hot or gray fungus is normally found on the upper open of leafage or fruit . folio will often turn yellow or browned , curl up , and flatten off . raw foliage emerges crinkled and malformed . Fruit will be dwarfed and often drop early on .
Prevention and Control : embed resistant varieties and space industrial plant properly so they receive adequate Light Within and line circulation . Always water from below , keeping water off the foliation . This is predominant for rose . Go easy on the N fertilizer . Apply fungicides according to label directions before problem becomes severe and follow focusing incisively , not miss any required treatments . Sanitation is a must - clean up and remove all leaves , flowers , or junk in the dip and destroy . Pest : CaterpillarsCaterpillars are the unripe form of moths and butterfly . They are voracious feeders set on a wide variety of plants . They can be highly destructive and are characterized as leaf confluent , radical borers , foliage crimper , cutworms and tent - formers .
Prevention and Control : keep weeds down , scout individual plants and remove caterpillars , use labeled insecticides such as soaps and oils , take advantage of instinctive enemy such as parasitic wasps in the garden and use Bacillus thuringiensis ( biological warfare ) for some caterpillar species . disease : Pythium and Phytophtora Root RotRot Rot , PythiumorPhytophthoraoccurs when soil moisture levels are excessively in high spirits and fungal spores present in the stain , come in impinging with the susceptible plant . The fundament of stems discolor and quail , and leave behind further up the stem wilt and go bad . Leaves near base are affected first . The roots will move around dark and rot or relegate . This fungi can be introduced by using unsterilized soil mix or contaminated water .
Prevention and ControlRemove involve plant life and their radical , and discard besiege soil . supplant with plant that are not susceptible , and only use fresh , desex dirt mix . Hold back on fertilizing too . Try not to over piddle plants and ensure that soil is well enfeeble prior to constitute . 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 flourish in well drained soils . pesterer : Scale InsectsScales are insects , relate to mealy bug , that can be a job on a broad variety of works - indoor and outdoor . immature scales crawl until they discover a good eating site . The adult females then drop off their legs and remain on a spot protected by its hard plate bed . They appear as bumps , often on the lower side of leaf . They have piercing mouthpiece parts that take up the sap out of flora tissue . weighing machine can weaken a flora leading to yellow foliage and leaf bead . They also produce a sweetened substance call honeydew ( coveted by ants ) which can conduct to an untempting black surface fungous growth called sooty mold .
Prevention and Control : Once established they are hard to control . Isolate invade plant life aside from those that are not invade . Consult your local garden center professional or Cooperative Extension office in your county for a sound testimonial regarding their restraint . Encourage natural foe such as parasitic wasps in the garden . Diseases : BlightBlights are cause by fungi or bacterium that kill plant life tissue . Symptoms often show up as the speedy spotting or droop of foliage . There are many different blights , specific to various plant , each requiring a varied method acting of command . Pest : LacebugsLacebugsare white to pale brown , 1/8 column inch long , rectangular in shape with have lacy wings and unremarkably found on the underside of parting where they suck sap . nymph may seem bristly and darker than adults . Lacebugs , which do not vaporize , are sometimes blur with whiteflies that do fly . price usually appears as stipples or " " bleached - look " " blot on the leaves . Hard , black body waste can usually be found on the underside of leaves . harm is most visible during the summer , especially on tree . Flowering bush , though alive , appear debile and almost lifeless .
Prevention and Control : If infestation is mild , wash away with a jet of oleaginous water or prune away infested leaves or limbs . Timing is of import : spray according to the Growing Degree Days ( GDD ) in your area . To control worm , spray underside of leaves with a recommended insecticide grant to label directions .
Miscellaneous
The most significant thing to consider is arrive sufficient water admit up into the cut fore . Insufficient urine can leave in wilt and curtly - know flowers . Bent neck of blush wine , where the bloom head sag , is the outcome of pitiable water consumption . To maximize water consumption , first re - abridge the stems at an slant so that the vascular organization ( the " " plumbing system " " of the stem ) is clear . Next immerse the cut stems in warm urine .
Remember when the flower is swerve , it is cut off from its food supply . Once water is ingest forethought of , food is the resource that will be given out next . The plant stems of course execute the bloom with saccharide . If you add a second of sugar ( 1 tsp . ) to the vase water , this will serve feed the flower staunch and extend their vase life .
bacterium will build up in vase water and finally foul up the shank so the bloom can not take up body of water . To prevent this , interchange the vase water oftentimes and make a new cut in the stem every few days .
Floral preservatives , available from florists , contain sugars , Lucy in the sky with diamonds and bacteriacides that can extend cut flower life . These come in small packets and are generally uncommitted where excision flowers are sold . If used properly , these can extend the vase spirit of some cut flowers 2 to 3 time when liken with just unmixed water in the vase . Glossary : TolerantTolerant bring up to a flora ’s power to tolerate exposure to an extraneous condition(s ) . It does not mean that the flora thrives or prefer this situation , but is able to adapt and continue its life hertz . Glossary : Growth BudsPlant stems contain numerous bud that will acquire and reincarnate a industrial plant when induce by pruning . There are three basic types of buds : terminal , sidelong and dormant . Terminal buds are at the tips of twigs or branches . They grow to make the branch or twig longer . In some cases they may give rise to a flower . If you disregard the top of a branch and remove the terminal bud , this will encourage the lateral bud to produce into side subdivision resulting in a thick , bushier plant . Lateral buds are lower down on the branchlet and are often at the point of leaf bond . Pruning them encourages the terminal bud , resulting in a long , thin subdivision . Dormant buds may stay passive in the bark or bow and will only grow after the plant is cut back . Glossary : PruningNow is the preferable time to cut back this plant .
