Step 1
Encore azalea are crossbreeds of natural spring - flower azaleas and summertime - bloom rhododendrons . By crossbreed these two shrubs , Encore azalea blooming in the bounce , summertime and fall . fertilise your Encore azaleas so that they flourish and originate bombastic , plentiful flowers .
Wait until after the last frost ( usually in March or April ) to fertilize Encore azaleas . If you imbed your azaleas in the spring or summer , put on fertilizer after institute . However , if you planted your Bush in the capitulation or winter , do n’t fertilize them until after the spring .
Step 2
fecundate using azalea fertilizer or azalea provender , as marked on the packaging . There are many brands of azalea feed and fertiliser , so read dosing instructions carefully . Generally , about a tablespoon of fertilizer is needed per plant . Some coarse-grained fertilizer are sprinkled over the etymon area of the plants , while others must first be dissolved in water before applying .
Step 3
Repeat fertilizing at specific intervals . Again , each brand of feed is dissimilar , but broadly speaking , you should reapply every one to two weeks .
Step 4
Stop fertilizing your Encore azalea after August . Fertilizer encourages new bud and you do n’t require new bud forming for the go about hibernating time of year .
My Encore Azaleas Are Not Blooming
Environment
Sometimes after implant new Encore azaleas in the ground , the plant hurt a shock and wo n’t flower until the next grow season . As long as the industrial plant is grow and look healthy , it will adapt to its environment the first produce time of year and bloom the next year . These azaleas are know for hop-skip a anthesis cycle when transplanted .
Light
Encore azaleas bloom for three season because of how the azalea has been breed . Because the plant can flower for so many seasons , it need to have at least four to six minute of direct sunlight to blossom . Plants do the effective in field where there is some afternoon shadowiness . If azaleas are plant in sphere without any shade during the Clarence Day , extra upkeep is needed to keep the territory moist .
Water
Long dry while can reduce bloom if the soil dries out . Azaleas necessitate moist soil to keep the works healthy and blooming . Manually water the stain during dry periods , giving the plants at least 1 inch of water once a week .
Fertilizer
Encore azaleas that are not blooming or have few blooms will profit from an app of plant food . Encore azaleas do n’t demand fertiliser in the first year , but gain with one covering every two week after the first grow time of year . The unspoiled fertilizer is one that has a 1 - 3 - 1 nitrogen - phosphate - K proportion . Phosphates , the middle identification number , promote flowering , and nitrogen , the first number , promote foliage growth , which you do n’t want if the plant life is develop healthy unripened leaf .
How to Care for Encore Azaleas
Keep Encore azaleas consistently moist throughout their first year . After the first year , Encore azalea do n’t need to be water regularly unless the weather is dry for prolonged times . If the atmospheric condition has been dry , water them well in tardy autumn , before the first freeze .
Fertilize Encore azaleas immediately after the first bloom with a plant food formulated specifically for azalea . This is all the fertilizer that Encore azalea need . Never fertilize in fall , because Modern ontogenesis will make the plant more susceptible to price during dusty weather .
Prune Encore azaleas as needed to maintain a pleasant shape . Otherwise , they involve no pruning , and it is n’t necessary to hit spent blooms . Any pruning should be done immediately after the first bloom , because later pruning will risk interfering with the 2nd bloom .
Step 5
Cover Encore azaleas with an insulated garden extend their first winter . After that time , a 3 to 4 - in layer of organic mulch such as pine acerate leaf or bark chips will be enough trade protection to isolate the roots . propagate the mulch around the plant , but do n’t pack it up against the tree trunk .
Step 6
Encore Azalea Problems
Reduced Flowering
For abundant efflorescence , azalea need four to six hour of sun per sidereal day . If planted in a shady land site , Encore azalea will not provide repeat blooming during the twelvemonth . However , too much hot summer sunshine will spite azalea and make heat stress . Select a internet site that meet morning time sun and good afternoon specter .
Pests
Many pests can damage azalea . Lacebugs are a common insect that dine on leaf chlorophyll , leave behind yellow speckles . Encore azalea is less vulnerable to lacebugs than other sort of azaleas . Petal fungal blight , triggered by Botrytis cinerea or Ovulinia azalea , causes a mold on flower petal .
Chlorosis
azalea that demonstrate chlorosis or yellowing leaves may be respond to their soil environs . azalea need well - drained soil at a pH of 5.5 . The turgid Encore azalea are more flexible regarding different soil pH levels than pocket-sized varieties of Encore azaleas , according to Louisiana State University .
When Can Encore Azaleas Be Moved?

All Encore azaleas can bloom three times per year , depending upon your location . They are grown like standard azalea but require just a flake more sun each day . The ' Autumn Royalty ' blooms are large , and gorgeous shade of purple .
Autumn Starlight
Another Encore azalea , this one with 3 - column inch white blooms with pink freckles and an occasional pink stripe , resonant of some petunia varieties . The short green , narrow foliage create a delicate backcloth for the flowers . Encore azalea prefer a somewhat acid soil , they only need to be fertilized once a year and are hardy to USDA zone 7 through 10 .
Pink Craze
This azalea , from the Bloom ' N Again ® line of azaleas , is cold hardy to -10 point F , and needs to be planted in an area of mottled sunlight . The " Pink Craze " will bloom in September and then again in the spring . The flower is a very clean , frail shade of pink .
How to Cut Back Azaleas

Prune the azaleas in early outflow before the blossom bloom . Once the azaleas begin to bloom , they will have plenteous time to grow to maturity and produce many blooms .
take away the branches from your azaleas that are shaded out by the other branches . These branches will finally kick the bucket out due to a lack of sunshine . murder these first .
crop off the diminished branches that do not bring out flowers after blooms appear . These branches will only practice valuable nutrition that the blooming branches could gain from . move out the non - flowering branch increases the be yr ’s blooms .
Take off the tops of the taller branches from the inside of the plant life . swerve them back to the sizing of the height of the outside branches . preclude the azalea from daze by removing only a few of the magniloquent branches at a time .
How to Fertilize Azaleas
rationalise off any all in or pathologic branches , as well as blow over bloom immediately after the flowers fade in mid - bound .
Remove the mulch by pulling it away from the base of the azalea . Spread slow - press release , high nitrogen granulated plant food around the plant , following the manufacturer ’s recommend pace of coating . Keep the granules of plant food from rival the stem of the plant as it can burn the bark . substitute the mulch .
Apply granulate fertilizer that is peculiarly formulated for azaleas around the fundament of the plant approximately six week after the first fertilizer app in the north and eight weeks in the south . apply the same method of app that you used to apply the eminent - nitrogen fertilizer and play along the producer ’s urge rates of app . Do not fertilize after July in the Union . In the due south , fertilize every eight weeks until other September .

For example , The Glen Dale azalea has chartreuse , orange , pinkish and red colours , while the Indica ( or Indian ) azalea has blanched , crimson and pinkish people of color .
Deciduous Azaleas
Deciduous azaleas can grow large with large leaves and will arise naturally in North America and Asia . They are n’t as common as evergreen plant azaleas . During the crepuscule time of year the parting diminish off , but during blooming time of year in fountain the colors wander from orange to magenta , yellow and white .
Species and Hybrids
Evergreen and deciduous azalea are either mintage azaleas or intercrossed azaleas . Species azaleas signify that it was crossbreed and insulate from other plants during production , whereas hybrid azalea are a mixture of azaleas and other plant coinage . Species azaleas maturate from seedling from their parent plants , and hybrid azaleas must be grown from cuttings of a mother plant life clone .
Azaleas With Brown Leaves
Distressed
Most azaleas prefer fond shade to full sun . If your azalea receive too much Dominicus and are not adequately watered they may come distressed and twist chocolate-brown . Azaleas transplanted during the heat of the day may also become distressed and initiate to plow brown .
Watering
Plants that are yellow and brown may indicate a watering problem . Too niggling water supply will go forth the works parched and brown . Too much water can create root rot , which drowns the ascendant with surplus water system . Carefully checkazalea stem ; they should be unannealed . If the roots feel mushy the industrial plant is meet from tooth root rot .
Seasonal Change
Deciduous azalea , which expend their leaves in the fall , will of course turn browned in the fall calendar month . Do n’t occupy ; leaves will develop back in the spring . If the leaves fall off during the summertime it may betoken to a problem such as a diseased flora .
Disease
foliage gall is a fungus that affect azaleas in the spring , alter leaves from gullible to white and then chocolate-brown . The North Carolina State University note that the disease does not harm the industrial plant , beyond making it look bad . slay affected leaves by handwriting and discard .

azalea lose leaves when they are infected with disease . Humid weather and overhead watering encourage folio post and other fungus problems . leaf develop fungus blotches and curl or fall off the plant . fungicide give readily usually control serious equipment casualty .
White Fly Treatment for Azaleas
Natural Enemies
Naturally occurring predators of the whitefly include lacewings , bigeyed bug , minute pirate bugs , certain species of dame mallet ( for instance Clitostethus arcuatus and Harmonia axyridis ) and parasites of the Encarsia species .
Leaf Removal
off leaves that have been infested with the nymphs and pupa of whitefly can help oneself reduce the population to an amount controllable by raw predator .
Traps
direct yellowed unenviable traps tightlipped to infested industrial plant at the level of the plague , out of direct sunlight , with the sticky part facing the plant . This strategy works best in conjugation with other anti - whitefly maneuver .
