As seen in many North Carolina gardens, the Knock Out rose, is one rose that looks good, blooms continuously during the growing season, and is virtually maintenance free. Not spraying required.
When you read this, I hope you aren’t too disappointed to find out there is very little you need to know or do to prune your Knock Out roses.
Anytime during the year, dead wood can be pruned away from the shrub, but any major pruning to shape the shrub rose should be done during the dormant season in late winter/ early spring.
When planting your Knock Out roses, give them room to grow their full size, so then the only attention you need to give the shrub rose, is you admiration. For an added bonus, Knock Out roses are self-cleaning meaning, so you don’t even need to deadhead; only if you want too.
It would seem the Knock Out rose is destined to be the perfect landscape shrub rose.
How to prune Knock Out roses
Using sharp by-pass pruning shears, begin by cutting off any deadwood. Next removed any spindly canes growing from the base of the shrub rose.
Look for an outward facing bud and cut just above the bud at a 45-degree angle sloping towards the bush.
So you can see pruning Knock Out roses isn’t particularly tricky, and doesn’t actually need to be done at all. But if desired, pruning while dormant and above a bud will reward you with vigorous growth and continuous blooms during the growing season.
