Native to cardinal and western China , the leatherleaf viburnum(Viburnum rhytidophyllum ) becomes a large , coarsely textured evergreen plant shrub 10 to 15 feet magniloquent and as as wide . Dr. Michael Dirr , generator of " Viburnums " notes that this shrub potentially reach a height 20 foot tall and 30 feet wide in ideal garden conditions in England . Nonetheless , Polypodium scouleri viburnum is a shrub for wide landscapes where winter low temperature do n’t drop below minus 10 to minus 15 degrees Fahrenheit , which kill the bud and stems . Generally , Viburnum grow with a by nature good structure and conformation . They do n’t require much pruning . Pruning must retain the mantrap of this shrub ’s large , glistening and rippled leaves , otherwise it begins to see untempting .
Step 1
analyse the overall condition of the leatherleaf viburnum shrub in former spring once wintertime coldness and frosts no longer endanger . The leaves course flag in cold conditions . Excessive cold or drying winds John Brown and kill leaves , and some outgrowth twig baksheesh and efflorescence buds . Once spring arrives , those branches and leaves that perished from the previous winter will be manifest .
Step 2
Prune off all dead or diseased wood , using hand pruners . Make the pruning cut 1/4 in above a lower living offshoot junction or yoke of dormant buds or greenish folio . Remove dead and diseased tissue paper anytime of yr they are run into , but early leap is ideal since raw development quickly responds and develops after pruning .
Step 3
abstain from more pruning on this shrub species until after it completes its flowering in mid- to late spring . The flower buds look like fuzzy browned Brassica oleracea botrytis heads on the top of branches . Pruning before these buds clear diminishes the leap floral showing and subsequent production of colourful berries later in summertime and fall .
Step 4
shave back errant or problematic branches on the shrub in late spring or early summertime to shape the shrub . Make the pruning cut 1/4 inch above a lower duet of leaves or offset join to reduce the ramification duration to your needs and design taste .
Step 5
cut down off suckering shoots from the stem of the bush ’s trunk , if any are present . Make the cutting off 1/2 to 1 column inch above the soil line or flush with the shrub ’s trunk , if that ’s where the farsighted , scraggly suckering stems originate . If you want the shrub to become prominent or fuller , do not prune away suckers .
Tip
Viburnum do not need intensive and extensive pruning – only tidying and balmy shaping to make a prissy plant and prevent branches from itch into building window dressing or becoming hazardous across pavement .
Warning
Avoid using shearing blades on the large leaves of leatherleaf viburnum . It causes temporary lachrymation of the leaves that tend to embrown and look shredded and sickly weeks subsequently . Do n’t trim past mid - summertime . Regrowth should n’t be under - germinate and belt down back by fall frost . Plus , the fussy bloom buds are already formed for next bounce . Do n’t remove them with an ill - clock pruning in late summer or fall .
