Easy Growing Knock Out Roses

Knock Out Roses

Knock out roses are super easy to grow and they’re available everywhere.  This rose is popular in North America and don’t be surprised when you drive into shopping centers or restaurants if they have several mixed in their landscaping.

I ended up with a couple 6-inch starter plants by mistake.  I failed to do my research first and then found myself fascinated with the foliage and quantity of buds each stem produced, the flowers are the size of a quarter.  I went ahead and purchased, having no idea how large the plant would grow.

I failed to read the plant label too – I know sometimes I should really slow down… I discovered very quickly three things:

  1.  They’re easy to grow
  2. A breeze to Transplant
  3. You can propagate year round (Down South)

Planting conditions were very basic and because they’re disease resistant they’re a natural choice for busy gardeners.  I think I may be a busy gardener…

They even have what I call a bloom rotation about every six – eight weeks.  In today’s images mine are at the end of a six week bloom period which means they’re getting ready to rest and then bloom all over again. Oh, and for all the southern gardeners these beauties are very heat tolerant.

They’re Easy to Grow

Let’s check into some of the perks that make the knock out rose an easy to grow plant for any garden space.  I’m not kidding when I say easy because this rose bush is a matter of planting correctly then letting them be.

  • Plant in direct sunlight.
  • Requires fertilized soil with good drainage.
  • Can tolerate Zone 5 winters.
  • Blooms from Spring – through late fall (down south about 8 months out of the year)
  • Fertilize after blooming twice a year.
  • Cover plant base with a good mulch and water from the roots when needed during the Spring/Summer.

When to Transplant

I transplanted this huge plant a couple seasons ago, it was originally one of those 6-inch pots I was telling you about and now it’s about 4 ft. high. Transplanting should take place during the fall or early spring when temperatures are steady, between 50 – 70 degrees.  If the plant wilts during the process have no fear because it will revive.

That happened to this rose because I transplanted on a whim off season and as a result lost the original foliage, but then it grew an entire new batch.  I don’t recommend pushing the limits but I can tell you from experience this plant is strong and can overcome my sometimes spur of the moment ideas.

Propagating is a Breeze

Propagating is also a breeze and can take place during pruning season from late winter to early spring.  Once again, I’ve taken cuttings during the summer and was able to root them in a glass of water in addition to fertilized soil.  I know, I’m always pushing those gardening rules…

The Knock roses are not my favorite but I was happy to learn more about them and thrilled they were so easy.  They might be just what you’re looking for if anyone is seeking a pretty show piece next to the front driveway or sidewalk.   A row of these as a hedge would look wonderful even when they’re not blooming.

    Hi Carole,

    Can you believe I have never grown them? I’ve not had a lot of luck with roses but these are not the typical David Austin picky plants that I have tried. Now that we have the new beds with lots of light I’m definitely going to try some. Thanks for the inspiration.

      I can’t believe that… I will tell you I prefer the drift roses better – both are super easy and beautiful. Me I’m just getting tired of picky plants life is to short… LOL

    Good Morning Carole…I am relieved to hear you are not directly in the path of Harvey!!!!!! I am constantly saying prayers for the people and animals affected by this storm.

    Now about the Knockout Roses…… I am going to try to transplant the one I have as it is not getting enough sunlight now as the shrubs around it have gotten bigger and are blocking a lot of light. As you suggested, I will be trying to root some stem cuttings in water AND soil just in case the transplant of the momma rose doesn’t make it. Will let you know how my attempts to root this bush go and which process is the most successful.

    My Knockout rose did get big and requires some pruning from time to time. There are a LOT of thorns on mine so I will cut it way back before I transplant. Thank you for letting me know that it will produce new growth. I will wrap the plant in a tarp to transfer to new location so that I don’t get scratched up too bad. The best part of this rose is that there are always some flowers on it. The foliage stays a shiny healthy looking green and you are so right, it survives a LOT OF NEGLECT….ha ha That fits me.

      Good Morning to you! Thank you so much for your prayers… We were at the property this morning clearing and getting things cleaned up for our arrival. I just posted something Magnolia is doing on my Facebook page to help South Texas – Pretty neat.

      Go for it – transplant that puppy with gusto – September would be a great time to do it cause I’m thinking your temperatures drop then. Those thorns oh my goodness horrible so remember to wear long sleeves too and gloves. These are things I often forget.. I should do an entire series on plants that don’t need a lot of attention because I do love gardening but sometimes it takes my attention away from others things I enjoy. Have a great day we’re off the property clearing this afternoon and tomorrow…

    Hi Carole,

    I have these at our cabin and love them. They don’t seem to require anything from me. I think the cabin just has what plants need because everything seems to flourish and gets little attention. Maybe the mist off the river…I don’t know…just good old mother nature.

    Hope all is well with you, Texas is in our thoughts and prayers

      That cabin sounds like a neat destination.. We’re north of Dallas – safe here. The devastation down south is heartbreaking….
