1. How Long Do Knockout Roses Bloom? How Long Will They Live?
Knockout roses will bloom from spring to late fall (around April – November). They have blooming cycles of about 5-6 weeks. This means you may see about 5-7 bloom cycles. Not all cycles will be heavy with blooms (plants need growing breaks too). It usually alternates between heavy and light blooms.
They can live for decades if you care for them properly. This means cutting back dead canes every 2-3 years to give the bush new life.
2. When Is The Best Time To Plant Them?
The best time to plant knockout roses is in the spring or fall. Make sure there is no threat of frost or they may not last through it.
3. Where Is The Best Place To Plant Them?
The best areas for knockout roses are ones that receive at least 6 hours of full sunlight (the more the merrier). You’ll want to give them about 3-4 feet of space so they have room to grow.
4. How Tall Do They Grow?
Knockout roses usually grow to a height of 3-4 feet. The Sunny Knockout Rose may reach 5 feet. In some cases, they can grow up to 6 feet tall, although it doesn’t happen often.
They usually spread out about 3-4 feet as well.
6. How Do You Grow Knockout Roses (A Quick Overview)
- Find an area that gets full sun for at least 6 hours per day. The soil should be fertile and well-drained
- Dig a hole about 2x as deep and wide as the container the rose is currently growing in
- Loosen the soil at the bottom of the hole
- Turn the pot upside down and gently remove the rose (gentle shaking/tapping should do the trick)
- Loosen the soil and roots at the bottom of the plant
- Add the rose in the hole and fill
- You can add manure or fertilizer to help aerate the soil
- Soak soil in water, allowing it to soak in as necessary
Adding mulch can help retain water, keep them cool, and prevent weeds. Check in on them for the next 3-4 weeks to ensure they are getting enough water.
Prune annually to shape them and prune back old/dying canes by ⅓ every 2-3 years to help give the bush new life.

Can I plant knock out roses in a big pot?
You can plant anything in a pot! But because of the cold temperatures in fall through late spring, you run the risk of the plants getting extra cold in a pot versus if they were in the ground. The ground offers more insulation to keep them warm during the cold months. The plant is not guaranteed to survive as long in a pot as it would in the ground. Hope that helps!
Which colors are the most hearty
The original Knockout roses are hardy for zones 5-9, we here in Nashville are in zone 7. So all colors of Knockout roses are hardy for this zone! Does that help answer your question?
Hello, I moved my knock off roses from one flower bed to another now it looks like its dead. Its all brown leaves no blooming insight. Is it dead.
It sounds like it might be going through transplant shock but it’s hard to say exactly without putting eyes on the plant. Transplant shock often results in wilting, browning, yellowing, or dropping of leaves. If you feel this may be correct, we recommend pruning back some of the plant to help reduce stress. Make thoughtful cuts that remove dead wood, crossing canes, and promote the growth of outward-facing buds. Also try root stimulating fertilizer to help the roots of your rose plant get established. Let us know how it goes! You can contact us on Facebook and Instagram if you have any other questions. Thank you!
