Pruning ornamentals
Ornamental shrubs and tree by no means all ask pruning ; certainly not regularly . A number profit from it , however , even though they may survive without it . Pruning ornamentals is simply a subject of assisting them to appear at their best .
Whether to prune or not to prune look to a great extent on the nature , functioning and growth characteristic of case-by-case species and specimens . The subject is not hard to understand .
Pruning before flowering
Many bush flower during the second half of summer and after . These should be prune betimes to permit meter enough for the production of the maximum amount of new growth which should carry flower of the best quality . However , not all shrubs which flower lately ask pruning — hibiscus , for illustration .
Among those shrubs that bloom in late summerare Buddleia davidii , Hypericum , deciduous ceanothus , Spiraea x bumalda , perovskias , Ceratostigma willmottianum , Leycesteria Taiwan , Hydrangea paniculata grandiflora , hardy fuchsias , andPotentilla fruticosain its many varietiesThe buddleia , perovskia and cerato stigma should be cut hard back in spring , to encourage as much young growth as possible ( in any casing , buddleias will become large and ungainly if entrust alone , even though they will survive ) . Treat deciduous ceanothus and the improbable Hypericum in this agency , too , if necessary though they do not demand it . Leycesteria may be necessitate to grow very tall ; if it is cut back in spring , it will do so . Hydrangea paniculatagrandiflorawill grow peculiarly vigorously and flower profusely if cut hard back in leap .
Spiraea x bumaldawill shortly make a plausibly unwanted thicket if it is not relieved of some of its older wood and its untested growth shorten in March

And , whilePotentilla fruticosararely requires much care , March is also the fourth dimension for any pruning that may be needed . Hardy fuchsias—F.magellanica riccartonii , for exemplar — when cut back in leap , squeeze up strong novel growth to bear fine flowers in late summertime . The quondam stems , tied together at their top , as the class wanes , will give someprotection to the crownwork against winterweather . Left unpruned , fuchsia blossom a little sooner , but in time can attain somewhat uncontrollable proportions .
Pruning after flowering
Early - bloom bush on the whole require to be prune after they have flowered . This leave new flowering wood a prospect to rise and mature in readiness for another year ’s presentation . It also allow for subsist unflowered wood scope for full development , so that it may also flower , in all likelihood the following year . The point is that many bush flower on one - yr - old and older wood . Sufficient of this must be promoted and encouraged to ensure unconstipated and worthwhile crops of peak .
The growth to cut off away are , conveniently enough , those that have just bloom . This , basically , makes much of the pruning of this form of shrub self - explanatory .
Forsythia is a good case of an early on - flowering bush call off for pruning after it has bloom . If the Book of Job is done before the leaf have to the full develop , flower wood is more easily seen and removed and the risk of sever the growth that will bloom the follow year is reduce . Forsythia is a bush which is better for minimal pruning , otherwise it may well discombobulate up much non - flowering , leafy increase . remotion of spent increase , only , therefore suits it very well as a general rule .

Kerria japonicaflowers on the early side and the flowered growing is well cut aside when the blooms have faded . Spiraea argutaandS. thunbergiirepay similar tending . Philadelphus , ormock orange , efflorescence in early summer , so does weigela or diervilla . These shrubs also call for pruning after they have finish up flowering . They shortly make unproductive thickets if the older emergence are not cut back away . keep clear of exhausted woodwind , they will remain in right shape , bring forth copious new emergence which will blossom when it ripen .
Syringas ( lilacs ) require the remotion of spent flowerheads when at last the petals have all browned and shrivelled . The buds below the flowerheads should not be damaged ; fresh anthesis growth will be make from these . lean , twiglike growth , can be veer away at the same sentence . Brooms ( cytisus ) , too , respond by grow newfangled growth if they have their honest-to-god shoot with developing seedpods murder . This pruning help to insure that there need be little or no cutting back into old wood as the plant get on , because brooms respond badly to this .
It should also be think back that there are lot of bush which do not need any pruning at all , even though they flower in thespring and summerperiod . The viburnums , which flower in fountain and summertime are examples . The wintertime - flowering coinage and hybrid also need little attending .
A telephone number of evergreens flower during the first half of the year . Berberis stenophyllais one , well - know for its sprays of prosperous - orange flowers and as an first-class elude bush . Berberis darwinii , with miniature holly - like leaves , produces its orange flowers in April and May . This , too , makes a proficient specimenshrub and hedging works . Both these evergreen plant may be pruned after they have blossom , though when they are grow as item-by-item specimen , such care is not essential . Indeed , left unpruned , full pleasure can be take from their annual harvest of bountiful dark fruits . When they are used for hedging intention , however , the need for control condition does develop .
No pruning needed
Mahonia aquifoliumandMahonia japonica aretwo very splashy , other - flowering evergreen which need no pruning at all . Nor does the evergreenGarrya elliptica , whose silver grey ament are so handsome during February , although it is near for remotion of its dead catkins . If necessary , light trim is permissible in May . However , those familiar with garrya ’s excellence for indoor decoration may have trimmed away some of the growth while its catkin were at their good .
Deciduous , wintertime - flowering bush such as daphne , chimonanthus and hamamelis , call for no pruning , though chimonanthus when grow against a wall will . Laterals will require to be abbreviate after flowering is over .
Evergreen escallonias , flowering in summer , need no regular pruning ; any which may become necessary should be done when flowering is over . Evergreen ceanothus , with the exception of those that blossom late , come in the same category , particularly when they are grown on walls .
magnolia , in world-wide , evergreen plant or deciduous , demand no pruning . As far asHydrangea macrophyllavarieties ( the mophead hydrangea ) are worry , congested old wood and spindly shoots should be trim back away in spring , though unconstipated pruning is unneeded . Faded flowerheads should be allowed to stay on the plants during the winter for afford some security to the young growth bud . Cut the dead heads away in spring .
The cosmopolitan discharge of comparatively non‑flowering evergreen , including conifer , grow off very satisfactorily without the pauperization for pruning , but should it become necessary to reduce their elevation , this should be done in former May . Where such evergreens are used as hedges , brightness clipping from early to previous summer may be done ; conifer , however , should be trimmed in former May or August . Rhododendrons need not be pruned unless in time they become straggly . The moderately firmly cutting back likely to be necessary under such circumstances should be done in April or May . This will result in the loss of blossom for a season or two , but recovery will follow . If it is feasible the seed pods of rhododendrons should be remove after the flowers have fallen , breaking them off carefully in guild not to damage the bud behind them .
trim and pinchingLavender , santolina and the evergreen greyish‑ leaved Senecio , do not demand pruning so much as being observe in good shape . To this end lavender and santolina should have spend flower - root removed after the bloom have blow over and then obtain a mere trim over in spring so as to keep them compact . If this is not done , lavender in particular will sidetrack , making it difficult to restore the bushes to effective stipulation . Avoid cutting back into old wood .
The remotion of awkwardly post branches in spring , will assistSenecio laxifolius , for good example , to maintain a good form . Mere pinching of soft growth crown during summer is an comfortable means of extinguish wayward shoots and encouraging bushiness . Hebes respond well to April pruning , should they postulate to be brought back under control . Pruning at this time is often necessary , in any casing , to take away frost - damaged shoot . Summer lop keeps these shrubs stocky .
Heathers ( erica and Calluna ) will thrive very well , left quite naturally , unpruned . On the other paw , those that flower in summer can be trimmed over in spring ; the wintertime and spring - blossom sort may be attended to after the flowers have faded . It must be accent that such pruning is not essential , even though it tends to better appearances and may be commodious in individual font .
Pruning for bark effects
A turn of bush and Sir Herbert Beerbohm Tree bear in particular brilliant bark if they are encouraged to throw up plenty of unexampled woodwind instrument . Examples are sure dogwoods such asComas alba sibirica — vividlyred — and willows suchas Salix vitellinabritzensis — glowing orange . Hard natural spring pruning is necessary to induce these to raise the maximum amount of vernal woods with the bright bark . Rubus giraldianusis one of the showy of the brambles with ` whitewash ’ stems . The strongest and most dramatic cane get up from intelligent plants which have been reduce back each year after flowering .
Wall shrubs and climbers
Many shrubs lend themselves to being train against walls , as well as making just freestanding specimens . Examples includeCotoneaster lacteaand pyracanthas , both evergreen plant , develop for their colourful autumn and wintertime fruit . Prune these softly during summer , in ordering to encourage them to develop as required .
genus Chaenomeles ( cydonia , japonica or blossoming quince ) is a deciduous bush which responds well to bulwark culture . It needs to be spurred back when grown in this room . Cut away lateral pass after efflorescence , and then pinch out the tips of resultant immature outgrowth during summertime . or else , leave the plant unpruned until former autumn , then shorten the sidelong shoot well back . Keep forwards - target growths ( breastwood ) cut back or filch back as they develop .
Wisteria is a mounter which need to be spur back , not only to encourage flowering , but to curtail the farseeing flexible growths which are characteristic and freely acquire at the expense of flowering growth . The end of July is the time when , if executable , all side growth made during the current year should be reduced to about 15 centimetre ( 6 in ) in distance . A further shortening to 25 cm ( 1 - 2 in ) may take place in November .
Hydrangea petiolaris , an fantabulous climber for north walls , conveniently requires no pruning at all . The Hedera , or common ivy , also ego - cling , can strictly utter , be leave alone too . But clipping them over in spring will keep them respectable and further the production of fresh vernal growing . The summertime - bloom fragrant whiteJasminum officinale , require no pruning either , though it may be thinned in spring , if necessary . sometime , neglected plants may need more drastic treatment . slim the growths of winter jasmine after flower , if necessary . Honeysuckle can be left alone , but sparse in leap , if necessary , too .
Clematis pruning is straightforward enough if given a little thought process and if basic fact about the genus are observe .
The small - flowered species can be left alone , though if the late flowering kinds among them rise too vigorously , severe pruning in February will counterbalance thing . After flowering is the time to attend to the early flowering kinds , should they become a little out of hand .
break the large - flowered varieties into their groups : motley go to thejackmaniiandviticellagroups demand severely cut back to the gloomy pair of goodly buds on each bow , every February , just as the buds commence to show gullible . Flowers are prolific on their new growth of the current year . Clematis in theflorida , lanuginosaandpatensgroups postulate no pruning at all to all intents and purpose , after the initial cutting back in February after planting . The may , however , want a piffling pruning in February , where growth definitely appears dead . And should growth ever become beyond control , then they should be cut back hard in February .
Ornamental trees
For all practical aim , ornamentaltrees call for no regular pruningat all . stagnant , pathological or unwanted wood may arise from fourth dimension to time , however , and this will have to be removed as with shrub . Deciduous trees , in the briny , should be pruned during the dormant time of year , avoid time period of hard frost . Butflowering cherries and plumsshould , wherever possible , obtain any necessary pruning after inflorescence , so as to ward off any problems with gumming and possible contagion from silver-tongued leaf disease .
inflorescence , ornamental tree may at times produce too much maturation and leaf at the disbursal of flower . This may be due to wrong feeding , but if the job is not solved by a modification of feed then antecedent - pruning may provide the solvent . This involves dig a trench in winter halfway round the tree diagram — about lm ( 3 ft ) from the trunk — sever the chief roots , and refilling the deep . The circle should be completed the following winter . It is not often necessary to recur to this method in as far as ornamental are concerned .
coniferous tree grown as specimen do not involve pruning , but any alterative treatment or absolutely necessary cutting back should be done in early May .
General winter pruning
This pruning , in oecumenical , should take aim at keeping bush and trees in sensible physical body , keep arm system simple-minded and open , and where appropriate , aiming at producing an adequate supplying of young healthy wood . During the inactive period , however , most deciduous specimens may need major renovation , especially if they have been overleap . Some shrubs are easily pruned in wintertime , when pruning becomes necessary , deciduous berberis , for example . Deciduous cotoneasters can also be wreak back under control , where such natural process is called for , in wintertime , rather in February .
Pruning principles
swing should be sportsmanlike and made back to a joint or grow point , or wealthy to a primary root word , so as to leave no split and stumps . Failure to do this will almost for certain conduct to dead hang-up . With no developing bud to sop up up sap , the wood dry and dice . bush to be trim down should be disregard right down .
Before making cutting off , particularly those that are a short ill at ease , it pay to decide sensibly the best steering for saw or secateurs , for example . Snags and stumps are very much more potential to arise where there has been crude and hasty cutting . Neither is necessary . Undercut large outgrowth before making principal cuts . They will lessen flawlessly , without stripping the bark .
Pruning must always be purposeful , directed towards assert unlittered and healthy specimen ; bearing in mind , of course , that some specimen are twiggy by nature . Pruning should not be simple snipping . It should be borne in mind that many bush and Tree ( as indicated above ) thrive well enough if they are left entirely alone . Pruning just for the saki of it is a very unsound practice .
You should never seek to reduce a specimen to a commodious shape , unless it is a hedging plant . Proper balance and innate coming into court are paramount . And , while by skilful pruning larger - grow specimens may be observe within bounds in confine spaces , it is nearly always full to have chosen , in the first place , shrubs or tree of suitable proportions .
All pruning is a topic of doing what is obviously best for single shrubs and tree , according to their natural habit .
Tools for the job
Christ Within to medium pruning may be done well enough with secateurs . There are many dissimilar makes . It may be wise to have two pairs , one for clear work and the other for punishing tasks . It is of import to prefer a pair which you could use comfortably . There are different styles , size and weight , and if work is to be done skilfully and easily , secateurs must outfit the hand properly and be used without tediousness and strain .
Cuts should always be made in the same plane as the secateur blades . Twisting will result in mangling cut and tense up the tool . Making sloping cuts for the intent of drop rain is wise , but cuts must still be made in the same planing machine as the secateur blades . Cuts should not , of course , be so aslant as to slice up wood out from behind a bud or growing point , thus allow it to dry out .
Secateurs as opposed to shears , should be used for crop or shaping certain hedges , where practicable . Examples admit the larger - foliaged chamaecyparis varieties and the thujas . cerise laurels and other with child - leaved evergreen plant should be pruned rather than clipped , otherwise the cut parting will turn brown and die , and count unsightly .
There are several powered pruner , drive from the galvanizing mains , portable source , gasoline engines , battery , by flexible cause , and by exponent take - off units from motor mowers or cultivators .
pruner , both short - arm and long , are utilitarian . Short - subdivision loppers or pruners enable tough cuts to be made with efficiency and f number where it is impracticable to use secateurs . Both anvil - cutand scissor - action form are usable . vane are short and very strong . foresighted limb loppers , their vane operate by retentive branch , a form of remote dominance , enable upstage and more inaccessible cut to be made .
There is a just range of pruning saws , both unmarried - sided and dual - sided . peculiarly utile is the Greek pruning saw , abruptly - handled or long . It is curved and taper and edit out on the back - cam stroke , making awkward cut very prosperous .
Pruning knives were once wide used , but have largely been supersede by secateurs for oecumenical pruning . Some craftsmen , however , still employ them , peculiarly in greenhouse . They are still useful to have on manus for world-wide purpose , and are still the best instrument for the all - significant task of paring polish the edges of tumid pruning cuts , especially those made by the adage . They should be used carefully ; cut are best made off from the user .
For the sake of efficiency and refuge allpruning toolsshould be keep in good working order , penetrating , clean and well - anoint .
blanched tip paint , bitumastic paint and proprietary Sir Herbert Beerbohm Tree - healing compounds should be used for seal large cut , to ensure that they heal rapidly .
