Who is growing Double Knock Outs? Do they bloom and repeat like regular KOs? Same size?

The city has put double KO's in some of the medians, and they have performed quite well. Good place for them-- they look OK when you drive by at 45 mph but there are a lot prettier roses for your yard. I'm particularly fond of Martha Gonzales for garden color-- a nonspot performer in heat. I also love Champlain, which like MG has very beautiful canes & foliage that compliment the color of the blooms, a nice clear red.

Hi Rosebud.
I planted one Double Knockout last year. It did not bloom as well as the regular Knockouts, at least for me. May do better this season as it will be more mature.
My best blooming Knockout variety is Blushing Knockout. I have 15 or so planted in a triangular bed on the street at ehe beginning of my Driveway. It's in bloom all summer and the color is much more noticeable than Knockout.
Last year was it's second so the plants were well established.

Yes, you can move it but I wouldn't wait until Memorial Day to do it. It should be blooming by then in SE MI. I would move it as soon as the soil is workable, late March or early April, and before it really starts to wake up. If you move it while it's still dormant it won't even know it's been moved when it wakes up. I'm in St Clair Shores and my roses usually start to come out of dormancy around the first week of April. Of course, that's all dependent on the weather we get. A good rule of thumb for our area is when the forsythias start to bloom for spring pruning and I'd move it just before that. The roses will be in the stores by then and you should be able to pick up another KO to plant too!

Odd, stunted growth on double pink KO

Florida roses share RRD susceptibility with all other roses; but (and this is where you have been lucky, so far) you have water on three sides and you seldom have winds from the north in May through September (this means you don't get cold fronts then either.) The vector mites for RRD are wingless and windborne. For them to carry RRD to Florida from areas to your north would require right wind condition + being a time of year, up north, when mite populations have built up. Florida isn't totally free of RRD. Two Hybrid Musks near Tallahassee were diagnosed with RRD over five years ago. Multiflora isn't common in the southern halves of the Gulf Coast states. That's a good thing for youall. A bad thing for youall is that R. laevigata can catch RRD. I know because mine has it, and I have a report of it just south of Charleston S.C. One thing on the pictures that is really interesting: the blooms on the affected roses. Your use of the word "Stunted" is a very good description of both leaves and petals. The blooms' petals are truly stunted but what caught my attention was the deep color of the petals. Of the many plants I've seen with RRD, I've never seen a situation when the petals got changes in the colors to make a deeper petal color. I've seen a lot of pink roses with RRD and pink Knock Outs with RRD....the colors have tended to become lighter, or splotchy. Do you have a scanner with your computer? Most scanners can be used as a microscope to see if you've a mite problem that is below the limit of what we see with the 'naked eye'. Ann

That's a lovely colour Brian. It's amazing it is flowering in such a short time considering our weather ...... Mind you this past week or so probably encouraged it a bit :) Regards Averil UK

Hello to two of my favorite Forumers.
I don't grow these but they are at the Woodland Park Rose Garden, where I last saw Karl.
Double knockout is, in my opinion a better Rose.
Bloom machine, very clean foliage and an overall better looking plant.
Personally I'd like more scent but none of them are listed as fragrant.

One thing that has been repeated regularly on Roses in Review is that the plant of DKO isn't as big as that of the original KO, and is more compact. Quite a few see that as an advantage.

Rosebud: one of my customers planted six. When I saw them they were so covered with blooms it was hard to find the bush underneath. He said they bloomed all summer, sometimes more than others, but always blooming. They are planted toward the back of his lot, easily visible from the deck. He said even when the blooms are old they look okay at that distance. They have the same little twiggy stemlets that give you plenty of places for blooms as do the regular Knockouts. He's not particularly knowledgeable gardener. Was feeding them the same thing he was feeding his other shrubs.

I thought they made an excellent landscaping addition. If I didn't want to buy 340 various other roses I'd add some to my place :-)

I like my knockout rose's better so far. I have one double but again last year was the first year I had it and the flowers are smaller then the knock out. Bloom bloomed the same for me. I was looking to tak out the double and replace it with another red knockout but I will give it one more year to see if I change my mind.
