Question
I read you answer about the cecile brunner that wasn't blooming.  My plant is in the ground.  It has had two blooming seasons with very few blooms once.  I can I tell if my plant blooms only once a year?  The nursery said all cb are hybrids that will provide repeat blooming.

Answer
Hello Phyllis and thank you for your question. The answer you read must have been from an earlier expert on this site, but no matter.
C鑓ile Brunner has two forms: the bush form and the climbing form.
It's a lovely Polyantha Old Garden Rose from 1881, and the climbing form is a sport which was discovered in 1894.  

The climbing C鑓ile is mainly a summer bloomer, but does tend to bloom heavier, with better formed flowers than the shrub form.  The nursery sounds a bit confused on their defintion of hybrids and repeat blooming, or in rose terms 'remontancy'. All roses accept the species or wild roses, are hybrids or sports of hybrids.  This is not a guarantee of repeat blooming.

The climbing form, if planted against a warm wall will bloom sporadically throughout the season, from early summer to early autumn.
It's a hungry rose and needs feeding during the growing season.  Be sure not to give it too much nitrogen! This causes lots of foliage but no flowers.  On fertilizer packages there will be three numbers like this:  N-P-K  10-10-10, for example. The first number is nitrogen, the second is Phosphorous and the third Potassium. The rose fertilizer you'll want to use - about twice yearly in spring and mid-summer- will have a low first number, a higher 2nd number and a mid-range third number.  An example might be: N-P-K is 5-20-13.  Also, always apply a mulch to your roses, preferably a hardwood mulch with 4-6 layers of black and white newspaper beneath it.  The paper will prevent weed seeds from germinating and break down over time into nitrogen and other organic substances and feed the soil your rose is in. With the mulch on top, your rose's soil will retain moisture better.

Deadheading (removing spent flowers) and removing suckers that develop below the bud union where the rose was grafted, if it's not on its own roots), and proper pruning will improve C鑓ile's performance. In spring, remove all dead, diseased or damaged wood. Then, cut back the the side-shoots to 6 inches or so off of the ground.  Every two years or so, remove the oldest cane at its bast.  This will cause the production of healthy new canes and more flowers.

I hope this help, and feel free to let me know if you have any more questions. Let me know how your rose fares if you have time!
Best wishes,
