According toClemson Cooperative Extension , rose bush pruning “ keep the plant healthy , ” ” promotes new growth , ” and “ encourages blossoming . ” However , modern reblooming President George W. Bush require much more of it than heirloom once - bloomers do . So , when see how to prune rosiness , determine which rose bush type you have .
Most modern cultivar such as hybrid tea roses , flower off and on throughout the summertime , work them rebloomers . Heirlooms such as albas , centifolias , damask , gallicas , and mosses usually develop only a single prominent flush of blooms in former summer , making them once bloomers . However , bourbon , China , intercrossed perpetual , noisette , Portland , and tea heirloom class of roses can rebloom .

Before You Begin
For pruning to be effective , it must be done at theright time . Prune reblooming arise George W. Bush , which blossom on new Sir Henry Wood , at the same sentence that forsythia shrub blossom in your geographical zone . That varies from January in California to April in some of the northeasterly state of matter . Another style to tell , according to Clemson , is when the leafage buds begin to swell . Prune once - blooming roseate bushes , which blossom on quondam wood , after they have finished their other summer blooming .
STEP 1: Remove old foliage, clean pruning tools, and don protective clothing.
Two week before you be after to prune everblooming rose wine , take out all the quondam foliage still clinging to them and rake up any devolve leavesbeneath the plant . conduct the junk forth to be trashed ; this will help prevent the banquet of rose bush diseases . Removing the old leaves will coerce the swelling of new folio buds on the George Bush and make pruning easier .
Before you begin , clean the blade of tools such as pruning shears and pruning hook with rubbing alcohol . Wear long heavy sleeves and long leather boxing glove to protect your arms and hands from the roses ’ thorns .
STEP 2: Prune dead, old, weak, or crossing canes from reblooming bushes.
First , lop off canes that are wholly dead , as proved by the pith inside them being dark-brown . Then prune back any that are partially dead to where the pith inside them is light-green - white with no undertone of John Brown in it . Make each cut at a 45 - academic degree angle , ¼ in above an outward - confront leaf bud .
You also will want to off honest-to-goodness grey-headed cane and those smaller than the diameter of a pencil , as well , as they will lean into the middle of the bush rather than incline outward . If two cane are scratch together , remove the weakest one .
STEP 3: Cut the remaining healthy canes back by about one-third.
In modest climates where the canes do n’t cash in one’s chips back much by nature , cut the canes back by one - third . In frigid zones , if rationalize out dead and dying Mrs. Henry Wood has already drastically concentrate the size of the bushes , you belike will require to skip this stair .
Keep in creative thinker that reblooming Bourbon dynasty , China , and noisette bushesdon’t take much pruningexcept the removal of beat rosaceous branches . However , hybrid perpetual , Portland , and heirloom tea roses can be cut back as drastically as you would a modern intercrossed tea rose .
STEP 4: Prune only lateral canes on climbers, training main canes horizontally.
When pruningclimbing rosaceous bushes , cut back back only the lateral canes , those branching out from the main canes , rather than the main canes themselves . Leave at least four leaf bud on each of those sidelong branches . Usepruning shearsfor canes up to ⅝ inch in diameter , loppersfor those up to 1½ in , and a pruning view for anything magnanimous than that .
Ben Hanna ofHeirloom Rosesnotes that “ to have your rosebush bring forth blooms from top to bottom , you must develop your principal canes to grow horizontally and admit the sidelong cane to grow up . ”
STEP 5: In midsummer, prune deadwood and old wood from once-blooming roses.
Once - flower roses do n’t require as much pruning . After they have finish flowering in midsummer , absent any dead cane or branches from them . You may also want to prune out one - third of the old surviving canes from each bush to regenerate it . They will let in the one that are grayest in color .
If you need to pare rose bushes that are outgrowing their distance , do that in midsummer also , to allow them sentence to convalesce before wintertime . Feel free todeadheadrepeat - flowering rose as blossom fade in summertime to promote raw flush . Do n’t do any pruning after later summer since it stimulate new growth that could be damaged by frost .
Final Thoughts
If you still are unsure about how to trim rosaceous bushes , keep in intellect that , although pruning is an crucial part of rose bush care , it is n’t dead necessary . So do n’t give up on the idea ofplanting a rose bushjust because you do n’t cognize how to prune it .
On the other hand , do n’t be afraid to give pruning a endeavour by following the direction above . As formerAmerican Rose Societypresident Bob Martin observe , the only mode to wholly conk out at pruning roses is to dress them off below the grafts .
