How do you care for knockout roses after they bloom?

When should knockout roses be cut back?
To maintain a size of 3–4′ w x 3–4′ h, Knock Out® Roses should be cut back once a year to 12” high. Check your rose bush from time to time in late winter/early spring, and when you start to see new shoots growing from the canes on your rose bush, that’s a good sign that it’s time to prune.
Can I prune roses in November?
For most gardeners, it’s time to put the garden to bed when the mercury starts dropping. But late winter is an ideal time to prune most roses, while the plants are dormant and unlikely to put out tender, new growth that would be damaged in freezing weather.

The main reason roses don’t bloom is they aren’t getting enough direct sunlight. You say your plants are in full sun, but keep in mind they need at least 8 hours of direct sun a day. If there’s a tree or building nearby, they might not be getting enough light. Also, don’t go heavy on the fertilizer.
Can I cut my knockout roses to the ground?
Roses should be cut to the ground only in winter, and only if the wood is seriously damaged or diseased and needs to be removed. That means when you cut into the stem, you are removing everything that is brown and withered, and making your cut where stems are still white and firm.
Can you prune roses that are budding?
Prune branches all over the Knock Out rose bush in late winter, after buds have formed and are coming out of their dormant winter state. Cut back new growth to bring branches back into line or reduce the size of the bush. You must prune before new growth appears. Snip branches at a 45-degree angle to promote growth.

How do you shape knockout roses?
Cut the stems back to a 5-leaf grouping or an outward-facing bud (if pruning during the growing season). Remove and discard any dead, crowded, crossed or rubbing branches. The goal is to open up the plant’s center and eliminate unnecessary suckers or random shoots. Cut the rose bush back by 1/3 to 1/2 the size.
Why are my roses growing so tall?
Your roses are growing tall because they aren’t receiving enough equal sunlight, or they haven’t been pruned recently enough. Roses are fast-growing plants (especially when grown in fertile soil), and when they aren’t getting enough light they are encouraged to grow tall.
How do you winterize roses?
After several days of below freezing temperatures, create a mound of soil, compost, shredded leaves or evergreens 8 to 10 inches deep over the base of the plant. Mounding keeps the rose uniformly cold, which reduces the chance of damage caused by cycles of freeze and thaw.
