How do you encourage a rose to repeat bloom?

I have 2 mature Cecile Brunner climbers growing on arches over our entry walkway. They face east and get all day sun at the top (rooftop height) and half a day's sun at the bottom. HMF notes on this rose: "occasional repeat later in the season." How do I encourage them to repeat bloom as much as possible?

Thanks

RE: How do you encourage a rose to repeat bloom?

Where to start? Usually, keeping the plant properly watered and healthy will provide it with the basics. If the plant WILL rebloom and isn't, with holding nitrogen while feeding with a Super Bloom type fertilizer might encourage repeat flowering from it. That would be low to no nitrogen with higher phosphorous and some potassium. Watch out for lawn food in its root zone. Grass fertilizer is usually high nitrogen. If these plants are anywhere near turf, you can be guaranteed their roots are all under that grass to grab the water and fertilizer applied to the grass.

The biggest determining factor is WHICH Cl. Cecile Brunner you have. Like many other climbing mutations, it can range from rampant, enormous growth with one spring or summer flowering, to nearly continuous bloom with more controlled growth. Figuring out which you have is determined by how the rose performs. I know of plants here which want to be 20' tall and flower only in spring. I've seen others which grew closer to 12' - 15' with age and little pruning and which flowered much of the summer, and some which didn't achieve that size and flowered virtually year round.

There is a clone of Cl. Cecile Brunner on the market which repeats well, as well as the common one found at many garden centers which is once flowering and much larger growing. Spray Cecile Brunner is the most reliable larger grower (10', give or take) which flowers most of the year in this climate. It's an intermediate mutation between the original seedling bush form and the larger climber and is able to be grown as a very large, self supporting shrub or a bit larger as a climber if given support.

So, alter your feeding of the rose to a Super Bloom type and keep everyone from applying ANY lawn food within many feet of these plants. Keep it well watered and healthy. Don't prune it unless you absolutely have to and see how it performs for you. IF it will rebloom, this should help encourage it to. If it won't, you may have to consider replacing it with either Spray Cecile Brunner (presuming you want Cecile on your arch) or something else which doesn't grow quite as large and provides more continuous color.

Lay a shovel by the climbers.

If they do not get the message, well at least the shovel is handy.

Love it! My dad used to love to tell how he'd talk to his old Ford (1950s) when the car misbehaved, he'd start talking out loud about how neat some newer model looked. He claimed the car listened and straightened up! I've done similarly. Talk to plants that don't behave and point out the compost heap in the yard. They sometimes listen! Kim

Lol, I swear that shovel thing must work! I've heard it time and again how someone threatened a rose with a shovel and it promptly started to grow and bloom!

Thanks Roseseek for the practical advice. Most likely these CB's are the garden center variety. They came with the house we just bought.

I'll also try the plant psychology too!

Thanks for this advice!
I planted a Climbing CB over twenty years ago, my husband didnt like it and tried to dig it up. It was a two year war,,,it was pruned back, hacked at..etc.

CB is now growing on the roof, usually blooms once a year but this year it started blooming in December and is still blooming. I havent got on the roof to prune it back.

I think this rose just has an attitude. When she blooms in spring I have sprays over 12 feet long - I put my potting bench under her (It is over an eight food spread) and grew an angel wing begonia up the branches. I hang little lanterns all over her too.

Sometimes we dont get what we think we want..but we learn to love what we have. I love this cantankerous old gal.
