Planting & Pruning
Can I transplant my roses?
Yes, it is okay to transplant your roses. The best time to transplant is late winter or early spring while the plant is still dormant and before new growth begins to push out. Click here for more detailed instructions.
I did not know to prune my Knock Out® roses in early spring. Is it too late?
If they were just planted this spring and have already begun to bloom, we would advise against cutting them back hard. Try deadheading instead. If they have been in the ground a few years and are well established, it's okay to trim, but don’t take off more than 1/3 of the growth. Save the hard 2/3 trim until late winter/early spring.
Is it safe to plant in late winter/early spring?
We recommend you check your 10-day weather forecast, and if there is no threat of frost, then it should be safe to plant. For detailed instruction on how to plant a Knock Out® Rose, click here.
Should I prune my roses each spring?
For best results, cut back Hybrid Tea, Floribunda, and Grandiflora roses in early spring (after the last hard frost) to 10" to 18". Remove all winter injured or damaged wood.
Prune climbing roses only as needed to control their size. Remove the older wood. Prune sparingly as the top is needed for bloom.
For shrub roses, to promote healthy growth and encourage lots of flowers, in early spring (after the last hard frost), simply use hedge trimmers or loppers to shear the shrub down to about 1/3 or 1/2 it's current height. It is okay if what remains is only about 12-18" above the ground.

How close together can I plant my Knock Out® Roses?
All of the Knock Out® Roses should be planted on 3' centers. This allows room for them to grow and have good air circulation.
Is pruning Knock Out® Roses the same as other roses?
In the Spring, after the last threat of frost has passed, cut back your roses (using hedge loppers) to about 12". This should make them grow to about 3'-4' tall by the end of the season.
For climbing roses, you want to prune your climbers in the winter or very early spring when the plants are dormant. Remove all suckers coming from below the bud union. Remove all dead or twiggy growth extending from the bud union. Cut all the flowering laterals that rise from the horizontal growing canes back to 2 or 3 buds.
What is the ideal time of year to plant Knock Out® Roses?
You can plant Knock Out® Roses in the spring or the fall.
Is it okay to plant Knock Out® Roses in containers?
Yes, it is fine to plant Knock Out® Roses in pots. If you want to plant them in containers, transplant into a container 2 sizes larger than the size pot the plant was currently in to give it room to grow. Also, be sure to place the pot in a sunny location and keep them well watered. Depending on where you live, you'll probably need to bring them inside over the winter.
