Green Dream -- Once again, a great deal depends upon what sort of roses you are growing. It's hard to advise, without knowing that.

If you are discussing modern Hybrid Tea or Floribunda Roses, budded onto rootstock, then a fairly light pruning is probably fine for them. Remember that in your climate, most roses are not (as lizard points out) going to go dormant at all, and certainly won't be losing canes to freezing temps.

If, OTOH, you are discussing Old Garden Roses (or others) growing on their own roots, pruning will likely not be needed this year, and maybe not even next year.

If you can find a pruning demonstration, that would help you A LOT.

It takes temperatures around 27-28 degrees to harm new growth on most repeat-blooming roses. If such temperatures are expected, it would be well to wait until you are safe from them before pruning.

I wonder why zone 9b and 10 growers prune in winter at all, since it is the best weather for growing and blooming, and freeze damage won't occur most winters. It may just be a habit derived from practices in Britain and the colder parts of the US. (I'm guilty too, since I used to prune in winter in zone 9b Florida.) It seems like a good time to prune in the western low desert would be after the summer heat breaks, or in Florida after the summer rainy season with its heavy blackspot pressure. Where freeze damage is not an issue, repeat-blooming roses can be pruned at any time. In Lakeland, FL, Malcolm Manners prunes in March in order to maximize bloom at graduation time on the FSC campus.

PS: Don't think of pruning as "cutting down." In warm climates, modern bush roses are pruned to around 3', and some types of roses are hardly pruned at all. Old tea and China roses would be harmed by severe pruning.

That's probably the one he wrote for the ARS American Rose early in 2014 based on the ARS funded research he has been doing as a three year project.

I emailed him a few years ago and asked a few questions. He said he is glad to talk with people who care about the research he is doing.

Thank you all. I haven't seen any disease or infestations, so I will just continue to pull off the dead (and ugly) leaves. I'm already seeing new bud eye growth, so I'll just continue doing what I have been doing.

You know, for the first year or so of growing my roses, I thought that after a while, I would know most of what I needed to know..... Silly me!! This is a much longer learning curve than I originally expected. But it's a FUN learning curve. I'm having a great time with it.

And happy new year to you all too.

Sounds like your plants are going through a normal process in winter. I do prune mine the week between Christmas and New Year. I do strip the leaves off so I force the plants into dormancy and give them a rest before spring. Come Feb/March, they will leaf out again and be beautiful. Although I do like the starkness of the garden in winter as well. It makes the spring all that more amazing.

My healthiest roses in my no spray, hot and humid Louisiana garden have been: sweet fragrance, freckles, Beverly, Mrs. B.R. can't, mons tillier, quietness, and molineaux. Hopefully they will continue to be healthy and provide more beautiful blooms! I can't wait for spring!

Let me tell everyone that the pictures on this thread have been so exquisite!!!! Such eye candy! This has been such a fun and interesting thread to see which roses have done well for everyone this year. Thanks for sharing your pictures and input on your roses. Lots of new roses and several that I would definitely like to get my hands on in the coming year. It was interesting to see how we all voted this year and there was a 3-way tie for the 2014 rose of the year........Julia's child, Love song, and Pope John Paul II. The runners up or ones that got more than one vote were: Beverly, double delight, mutabilis, lady of shalott, south Africa, peace, gold medal, Marie van houtte, tiffany, belindas dream, hot cocoa, Gemini, and don juan. I think we should do this again next year to see how we all fared and see if our favorites are still the same or have changed given all the variables we may encounter in the coming year. Thanks to all who participated and Happy New Year to everyone! May everything come up rosey in the new year! Shannon

Welcome back, Diane, and a very happy new year to you and everyone else. Your rose is so beautiful; I really love all the different shadings of Augusta Luise, not to mention its ruffles.

Here in a very southern part of southern California we've had snow and temperatures hovering around the 30's at night. Before that we had a bit of rain so all that moisture is welcome. Further inland there was even more snow, and naturally everyone freaks out as though this were some incredible phenomenon. In Minnesota they probably would have considered this a balmy spring day.

I'm glad too, to see you posting again, Diane. And thankyou, for raving about Julia Child. I have my own now, and she's so healthy and well-shaped, and takes baking afternoon sun without batting an eye.

I got some new ones in last spring and was delighted with all of them. Chartreuse de Parme was my favorite, just a gorgeous color, very full blooms, intoxicating scent and the blooms were extremely long lasting. I remember the fragrance persisted for at least a week. The plant seems to have good vigor too. Dames de Chenonceau is gorgeous, Henri Matisse has big striped blooms with good repeat,
Nahema has a powerful fragrance , exquisite beauty and good vigor. Alfred Sisley is one of my favorite striped roses. It's incredibly healthy, repeats fast, love the colors, and it has a lot of hips in fall. Makes a good shrubby plant. I'm impressed with Delbards.

Delbards are spectacular, but do better in warm climates (on a whole). Delbard has a large variety however. Some more cold hardy than others. But a lot of them do best in warm climates. And not all have scent. I grow Eden, papi Delbard, nahema and dames de chennonceau ( my favorite of all). There are SO many types of roses however, so don't limit yourself to one breeder. See what does best in your climate. There is a rose (many in fact) for every garden.

I do appreciate the further information on Florentina. It is good to know that the canes are easily trainable which makes it a good candidate for my fence in full sun. I was hoping that there would be *some* fragrance as Palatine's description says "fragrant rose" - I'd even settle for it being faint, not expecting the fragrance of an old rose or even an Austin. Well, I guess I will just have to give it a try. Disease free is another desirable quality in my no-spray garden, so thank you Cynthia for your experience.
I'll let you all know down the road how it does for me!

We try to be honest about the fragrance and not promise what we don't think is present. I spend a lot of time evaluating fragrance in roses. You are right it seems there are not many fragrant climbers. I think Kordes Golden Gate has moderate spicy fragrance. Another Kordes with very good fragrance and very good cold hardiness is Laguna. There are repeated very good reports on cold hardiness in the Midwest. it is an ADR winner with really great disease resistance.

Thanks Henry, I ordered Ice Cap last month. I'm thinking it is a double form of White Out. Being short and scentless is perfect here as they are seldom bothered by the hordes of Japanese Beatles that we have here.

I grew Blaze in a pot and it did great. You do have to have a BIG pot though. Not just for the root system but also to counter weight all that top growth so it doesn't topple over. The pot I used was about 2 1/2 X 2 1/2 feet and I had a small trellis in the pot to tie the canes to. It was in that pot for 5 years before I got it in the ground. Now that I think of it, it bloomed more in the pot than it does in the ground!

Here's Crepuscule growing in a large pot by my front door. It is rarely watered and has a lot of competition from English ivy growing in the same pot. I throw my mop water on it.
It is starting to decline some but has done fairly well for five years or so. I have a large Constance Spry plant in a pot but it rooted through the hole a long time ago. Used to have a big Lavender Lassie in a big pot. It got too big for the area it was in. It also had rooted through the hole.

You might try Jack Falker's method of using leaves to protect them. Keep in mind it's cold winds that cause the most damage. So surrounding them with a wind barrier is the best thing you can do.

Also if you lose some of the tops that's okay. You'll just prune that off in early spring. focus on the bottom 12" or so.

Here is a link that might be useful: Jack's blog post

I haven't seen any actual leaves yet but there is definitely some plump red leaf buds out there. Nothing you can really do about it. Just leave them alone and hope for the best. This freeze and thaw stuff is the real culprit that kills most roses. And the freeze is already on its way for this coming week. If the roses went into winter healthy and you gave the crowns some protection even if you lose some of the canes they should still be fine and come back next spring.

"Preliminary data showed that epsom salt application (in addition to N-P-K), on a monthly schedule, did not reduce the disease incidence but did reduce defoliation compared to plants receiving no secondary nutrients. However, the plants treated with epsom salts or CaCl2 were less vigorous and produced fewer flowers than nontreated plants or plants treated with calcium sulfate (Figure 2)."

http://www.aaes.auburn.edu/comm/pubs/highlightsonline/summer96/blackspot.htm
_________________________________________
"As to the claim of the effectiveness of Epsom salts to combat fungus infections in plants, no real evidence supports this. Reports done by Washington State University and other research facilities have shown that Epsom salts have no affect on apple scab or other mildews. However, many gardening enthusiasts and websites, including the National Gardening Association, say that applying Epsom salts can produce healthier plants by providing magnesium to the soil and reducing leaf loss."

I gathered from Bierkreek that adding sugar to one's soil helps stimulate the growth of mychrorriza funghi (please excuse eventual spelling error). In fact, this year,I decided to try sprinkling white sugar around in my garden; NOT hundreds of pounds of it,of course;just a bit in each new rose hole,plus a couple bags sprinkled sparsely around on the soil. I can't see what harm it could do...

Have you considered purchasing it as a own-root rose? High Country Roses has it. They told me they only carry varieties that they believe do well own-root. The climbing rose I ordered from them is doing very well. Best wishes in your search.

I have this one along with Hypnotized and Neil Diamond on order for the spring. Can't wait for some new striped roses, they are always such a surprise with every bloom! I can't find either Hypnotized or Daring Spirit on hmf just yet but I loved your shot of Neil Diamond!!
