Hello, all! Very happy to find this thread today!
I'm having an indoor rose aphid problem. I read through the posts - and some other pages as well - and am going to try the garlic w/ 1 tsp soap mix on my rose when I get home. I will post about how it turns out!

For now though - this is the infestation I've got. :/
I am a little bit new to gardening; I always helped my Father with his rose garden when I was growing up, but this year is my first year with my own. I've had indoor potted roses for a few years, usually minis. I've never really had many problems with them before though. Minis are pretty tough lil guys. (I actually have one that is planted in my garden that is still blooming despite the snow on the ground!)

This time I have a David Austin Charity rose that I'm attempting to get started indoors. I purchased it late in the season, and I did not think it was established enough to survive outdoors with my planted minis during the winter. Therefore, I am not trying so much to get a lot of blooms, but rather keep it alive and as healthy as possible until spring when I can transplant it to its permanent home.

I just wanted to post this picture before I go spraying things in case there were any suggestions specific to this. :) I'm fairly certain that these are adult winged female aphids. Before I left for Thanksgiving vacation I found the little green aphids all over it, and I gave it a hard spraying and pruned it back hoping that would help. When I returned, it looks like this now. :(

I grew a hybrid tea (Black Madonna, zone 6) a few years ago in a very large clay pot outside. I was overwintering it in the unheated, attached garage. It had done well overwintering in there the year before. I brought it out into the living room, (I think it was in February, I was starving for flowers!) where there were large South-facing windows. It leafed out, and produced two beautiful blooms that helped with my February-rose Fever! The blooms hadn't faded yet, but already in a few days they were quite heavily infested with spider mites. Once it was safe outside, I brought it out. It suffered for a while that summer from the spider mite infestation. I think I might try again this winter, and prune/pinch it to prevent it from being leggy, apply insecticidal soap, mist it, maybe I'll keep a bag of manure in the garage to feed it once a month or so... Boy was it great though to have such big beautiful blooms for a bit in the dead of winter! We get alot of snow and usually a week of -40C every winter. I'd be willing to try it again.

Alison, make the distinction between canes (or stems) and leaves. You can remove leaves without cutting the canes.
Leaves use water at a prodigious rate until they wilt. Canes lose relatively little water, and they contain stored nutrients that will help restart growth once the roots can get enough water. I'd suggest stripping off half the leaves, starting at the top, because new growth will come later at the top. If it's a big awkward plant, cut the canes back if you want to. If digging left few roots attached to soil, remove more than half of the leaves, or even all of them.

Lawn or deck chairs are handy for shading transplants. If you remove all the leaves, there is no need to shade.

I'm sorry some people misunderstood the article I referred to - it does not refer only to trees. .

I agree that more work might need to be done regarding transplanting roses in dry climates like SoCal. The research that I am aware of was done in moderate climates - places like OH (where the OP lives) and NJ (where I live). That was the context I was replying in - I would not tell someone who lives in a place like SoCal what to do.

BTW, for a long time I DID top prune woody plants at transplanting time - not just roses - because that was the way I had always done it. I didn't base that on any science or on any real research behind the practice - it was just the way it was. I never questioned it until I became aware of the work that had been done on no-prune transplanting. . For about five years now, I have not top pruned when transplanting roses, and haven't had any problems doing it that way.

In my experience with Bayer Disease Control for Roses etc, you get good control by just covering the top surfaces. I recommend that you try that to reduce the amount of fungicide used.

When I used sulfur, I was careful to spray both surfaces, because sulfur washes off easily and isn't super effective.

The great majority of particular local blackspot infections occur on the upper leaf surface. How can you tell the difference? Such spots do not usually bleed through to the lower surface. But spots that start on the lower surface do bleed through to the upper a few days later.

I spray a quick blast under then a good coating on top. Works fine for me. If you're roses look good, don't mess with anything. "If it aint broke, don't try to fix it."

First off is that garden soil in those pots?
Heavy soils do not work well in pots.
Use a lighter mixture of a potting soil or mix.

Well a just-planted body-bag is likely not going to have mature flowers. Give it time to settle in and you may get many many more petals and better form and a more accurate ID.

Babies can't run marathons; baby roses don't produce the flowers they are capable of producing when established.

I often wonder about this. I planted a Garden Party and a Peace rose at the same time (same source) and both have flowered, too. They are both very full, petal wise. I understand they are also related, which may explain the habit.
I guess some roses just have to grow into themselves! I will give it some time and see if this one does the same.

Andrea, sometimes GW times you out. I don't know why, but sometimes it does. I've found by hitting the back button, it takes me back to the screen where I was typing my post. I often copy it from here, take it to my email program and paste it into an empty email to be worked until I'm happy with it. I can easily check spelling there, too. Once completed, I copy it there and bring it here to paste into the window to be posted. The next time you're timed out, try your back arrow or back button and see if that takes you back where you wrote what you wanted. You can then copy and bring it forward. Hope it helps. Kim

Thank you so much Kim. Great idea. It does take me too long to get a message right, my home keyboard is rotten (work KB is great). And I'm not the greatest typist.

Thanks again,

andrea

If you cut the prickle back in any way it will NOT grow back. Don't break them off because that can introduce different problems but clipping them off so they are not so sharp should work fairly well.

On closer look, I see that there are hundreds of tiny thorns around the large ones. I am thinking that cutting a sheet of hard plastic and making a loose tube around that section of the branch might be a better solution.

Bumping. I would love to know as well. :)

Made a quick trip to the NY Botanical Garden yesterday. Saw they use Peach (or was it Coral?) drift roses to hedge some areas. Lovely effect.

Well, she got it mostly right. Thankfully, she does state it is necessary to destroy roses with the disease.

The acres of Knockouts used in landscaping around here has turned into acres of witches brooms. And no one is doing anything other than hard pruning to get rid of the growth. So far, about 80% of the KOs seem to be living just fine with the disease. The existing non altered canes continue to produce normal growth and blooms. And the affected canes produce monstrosities. The hard pruning that the blow and go guys practice rarely kills them. They just continue spreading the disease far and wide on the wind, with no one caring to do anything about it.

I've lot around 200 roses to RR.

I'm not planting any more.

It's too heartbreaking.

I think the belief that excess P promotes bloom is an old wives' tale. However, I don't know of any trial to point to. Excess P does suppress beneficial mycorrhizal fungi and does cause trace nutrient deficiencies.

Same here... I had a soil test done a couple years ago and everything was good... soft clay soil...
I have been applying mulch, compost, etc for years.
That's all I need here as the use of fertilizer (esp granular) has caused me some problems...
So I'm going back to what works best for me here...
Applying mulch, compost, etc. on top of soil...
You know even 1-2 cups of coffee grounds has caused me slight problems here at times also...
Just don't need it here...

I agree with the other posters 100% about P...

Thank you, Henry, for the above links, I find them very fascinating. I am always curious about the role of sugar in plant growth, much appreciated.

"My understanding is that the Bayer fungicide (not the Bayer 3-in-1 or 2-in-1) is not harmful to bees."

Kate is right, the Bayer tebuconazole (Disease Control for Roses, Flowers and Shrubs) is rated a minimal hazard to bees, birds, and earthworms. It is a significant hazard to aquatic creatures--keep it away from streams and ponds.

Thank you! I got lazy this year and used the Bayer Advanced 3 in 1(because I didn't have to spray, I just add water and pour it around the roots,) and now I am feeling guilty about it.

Even if they are suckers, they will bloom - suckers are just another kind of rose. just wait and take pictures.

They will bloom, but not during the season that they first grew out.

The question is, did it die because of the stems turning black, or did the stems turn black because it died of a root infection that cut circulation off to the stems? You can see by the wrinkled texture of the still-green portion of the canes that no circulation is getting up to the canes from the roots. They are shriveled.

Look at the roots, are they rotted, soft, gooey? Did the soil smell sour and foetid when you pulled the rose out of the ground? Is the area constantly soggy? Those conditions would point to rot.

Is it possible a large pet dog urinated several times on the rose and gave it such a blast of ammonia that the rose was poisoned? Did it accidentally get too much fertilizer? That would point to death by chemical damage.

A bacterial infection would be another possible culprit--are there other problem plants in your yard?

Thanks everyone. I've cleared out the pachysandra, but left the alium. I cut all of the canes just below where it's brown, above the lowest node. I used sharp cutters and cleaned them with part 1 bleach/9 water between cuts. I'll watch it closely and hopefully it rebounds. I'd hate to think I killed a rose that's been around for so long.

I appreciate all of your help. Thanks again.

Looks good, Becifer - I can already hear the rose breathing a sigh of relief and getting ready to stretch its arms out to bloom. In this latest photo, it does look like you have a grafted rose with the graft about 2" above the soil. At least by wintertime, you'll want to protect that graft by adding soil around the base of the plant. You can certainly build up the soil around the base of the plant to cover the graft now if you wish, as opposed to trying to rebury the rose with graft deeper (which is wa-a-a-a-y too much work for the likes of me). I figure that roses are survivors, and if this rose has been through many of your winters it's liable to handle itself regardless of too many details of what you do with it. You're off to a great start regardless.

If you want to encourage it to put out some new branches ("basal breaks") from the base of the plant, it's useful to work some alfalfa into the soil near the rose. I'm pretty lazy and just sprinkle on some alfalfa hay and rustle it into the top layer of soil or mulch near the rose. Alfalfa is usually sold as animal feed, and you can see small bags of it sold in the guinea pig/hamster section if you have the one rose and don't want to buy the 50 lb. horse bales like me! Just avoid the ones that have added salts if you can.

Have fun and post us pictures of the rose when it blooms for you!
