Hardy in USDA zones 5 through 9 , they produce big pink flower in late spring to former summer and may bloom periodically after the first flush of flowers . Pruning Queen Elizabeth roses regularly keeps these vigorous growers straighten out and aid prevent disease and cuss infestations . Prune Queen Elizabeth roses to maintain shape , increase air flow around cane , eliminate weak and discredited increment that could lead to insect and disease infestations and to encourage re - flower after the first flush of flower .
Step 1
Prune Queen Elizabeth roses with acuate pruning shears . Disinfect the pruning shears between plants . Disinfect pruning shears between cuts if the rose you are pruning is diseased . Use a 10 pct blanching agent / water mix as your disinfectant . put the 10 per centum bleach / urine mix in the plastic pail for ease of dipping .
Step 2
Cut 1/3 of the honest-to-goodness cane to the ground . erstwhile canes are dark green or greenish - brownish and are not ductile . Make cuts on a 45 - degree angle .
Step 3
Cut back debile increase ( foresighted , floppy canes littler in diameter than a No . 2 pencil ) and cane that are cross or rubbing other canes to the ground .
Step 4
Remove dead or diseased cane at any metre of the year . Make cuts on a 45 - stage angle 1 to 2 inches into healthy ontogeny . The marrow ( cloth inside the center of the cane ) will be white . Make cuts 1/4 inch above a healthy outward - face bud ( the greenish - brown bump where new growth emerges ) .
Step 5
Remove faded flowers . This function is sleep together as deadheading . Make cuts on a 45 - degree angle above an outwards - facing bud .
Tip
Prune Queen Elizabeth roses in the springtime just as bud are startle to swell . Pruning cuts made on a 45 - degree slant are less likely to act as a portal for rot or bacterial disease . This is because water lam off the 45 - degree angle cut rather than sitting on and than sinking into the cane , as happens with horizontal cut . Leave three to five canes per Queen Elizabeth rose bush even if it means waive pruning .
Warning
Dispose of rosaceous thinning by thrust them away or burning them . Doing this will foreclose the counterpane of bacterial disease and cuss infestations . Thin , lank ontogenesis will not acquire flowers and is more prone to disease and insect damage . Do not crush or tear cane when making cuts . This damages level-headed tissue paper , which can lead to bacterial disease or pest infestation .
