Tips and techniques for pruning shrub roses for maximum blooms.
Shrub roses are a group of roses that include landcape roses, modern English roses and rugosas.
The most popular shrub roses are the Knockout rose series. Very easy to care for shrub roses.
Most of the these shrubs will respond very well to an annual clean up and pruning, done in spring or late winter.
Prune back vigorous shoots that originates close to the ground by a third.
Try to prune just above a bud eye. Check the drawing on this page.
The canes, branches coming off these, can be shortened to about 8-12 inches long.
Don't be afraid if you make a "wrong cut". Rose bushes are rather tough and can take a bad pruning now and then.
When you have several annual pruning experiences behind you, it will be a lot easier.
You should also prune for form, and otherwise try to maintain a natural shape.Rugosa shrub roses do best with minimal pruning.
Just cut out dead and damaged wood.
It's ideal to plant rose shrubs so they have enough room to grow naturally and not be crowded.
But if they are growing too large for their allotted space, and/or you must control their size, you can cut back rather severely in spring, to just a foot or two.
