Actually they are a cross between Rugosa and Tea Roses.

quoting the article furnished above:

"If you are pruning to control the shape, wait until the second season of growth. After that, you may only need to prune every three years or whenever you want to shape the rose."

.

How far back should the knockouts be pruned? Do you do this the first year? Thanks for any help.

Did you read the link provided by Skyguy? Good information.

Knock Outs are darn near bullet proof and grow prolifically. If you have the time and inclination .... pinching wilted blooms will help cause greater blooming. I prune as needed throughout the year and do a major one (to about waist high) in early spring. Followed by a fertilizing when freeze danger has passed.

I really like the Job's Organic Knock Out Rose Fertilizer. Smells like poop because it is mostly "chicken manure" ..... works great! 2-3 feeding per year is all they will need.

My Knock Out Standard looked so straggly when I came down in March that I almost replaced it. Then I decided to prune it right back and fertilized it and it is now blooming its head off. The question is should I cut it back again just before we leave at the end of May and fertilize again? I was thinking that if I did that the blooms would be out again in Sept-Oct when we return til the end of Dec. Then I wondered if it should be cut back again at the end of Nov. before winter or do I leave it til March. Any help is appreciated.
