I am growing this one in Dallas. I have pampered it as I love the bloom color. It's been somewhat disappointing. It's grown into a massive, gangly thorny climber. It didn't bloom for its first three years. It bloomed three times last summer. Unfortunately, the blooms are very short lived in Tx heat. Rover seems to have an insatiable thirst. I think he would be happier in a cooler summer climate with a lot more rain.

I agree with some kind of burn. The edges don't look yellow as much as they do tan and crunchy. Whether from fertilizer burn or just high heat it should be fine when the new leaves grow out.

I live up in the N.E. corner of GA. Your foliage looks OK for this time of year. Just keep everything watered good. It wouldn't hurt one bit to drag the hose out and give the bush's a good watering down during the early morning's. I wash off my bush's at least once a week. I also use the same spray you use and have no black spot.

Mister Lincoln goes straight up. Just the nature of the beast. Just remember this, fall is just around the corner.

Julia Child can get to 6'X6'--maybe not in all climates, but in hot ones I wouldn't be surprised if she does. My photo shows just the top part of Julia. Diane

I was going to vote for Love and Peace too. Especially because of the deep yellow in the center. Don't you just love Aldi roses. They are such a great bargain. Mine have all done well. I have about 6-7

I love it when you get a deal on them and they turn out so well. I just wish mine were labelled-- so I could pick up another!

This is excellent advice. Especially since sometimes the water just doesn't go where it's needed. Sometimes very dry soil repels water and although you think it's soaking it, it may not be. I think I'll go get one today.

If this begins at the bottom of the plant and creeps up, it could be magnesium deficiency. If so, 1/4 cup epsom salts would fix.

Sorry for not replying sooner, I think it ultimately ended up being a lack of water- it's been hot here in California and we've been trying to reduce water usage so it's putting a strain on the plants. I've been watering them a little more and there's been some healthy new growth with no sign of crispiness so they're doing better now. I did add some epsom salts for good measure though! Thank you!

Different. Fewer petals. Different coloration, still nice looking.

Likely these roses were infected during a "canning" operation in Texas or some other southern area where the disease is active. Or I guess some roses are still grown in Texas. Florida probably doesn't have enough wild roses to serve as a bridge for RRD, but the disease could take hold in any city in the country if nurseries carry infected stock.

I would like to know where the infected roses came from.

The following was stated:

" Reducing the severity of the symptoms....so we can keep sick plants around waiting for additional vectors to find them and spread it? Balderdash"

H.Kuska comment: It is my understanding that there are roses that are resistant to natural in field infection. What does this mean? Some observations may be due to the mites not recognizing the leaf surface as belonging to a rose. We do not have to worry about these spreading the infection as they were never bitten. However, what about the others that were bitten but were able to control the infection naturally? Are they going to be "Typhoid Marys" of the rose world? This appears to be a concern of the above quote.

My first thought is that the "surviving rose" may have a virus concentration below the amount necessary to overcome most clean roses' natural defense system.

The virus plant world is not black and white. There are plants that do not get infected by a particular virus (complete resistance). There are plants that exhibit partial resistance, and there are plants that exhibit so little resistance that the virus kills it.

If we add an external chemical that boosts the immune system of a plant so that the plant does not die from the infection, are we providing the plant the opportunity to "fine tune" its immune system naturally so that it will be able to fight the virus in the future without addition application of the external chemical? The literature supports this possibility. This is called systemic acquired resistance against plant viruses.

https://www.google.com/webhp?hl=en&authuser=0&gws_rd=ssl#q=systemic+acquired+resistance+against+plant+viruses&newwindow=1&hl=en&authuser=0&start=90

Can this plant that has acquired SAR pass it on to the next generation? Evidence is now being accumulated that supports the possibility of "next-generation systemic acquired resistance".

I had my poor new Oklahoma in the shade because the first blooms all burned up before they were even half open and that was in May. it was not happy. Once I moved it back out in the sun a couple weeks ago, boom! Lots of new growth and buds, but they are doing the same thing. I'm hoping for cooler weather so I can see what the blooms look like.

This is not just happening in Oklahoma. We had a very long, cool gray spring and the roses showed the same effects. We haven't really had any of the usual heat we have in summer and now they seem to be putting on a little more size. So what ever odd weather you're having I'm sure that the roses are blooming differently in relation to those conditions.

Many of the RoundUp and pruning advice replies that you have received appear to apply to cases where the RoundUp problem started due to spray reaching the outer leaves or canes(drift). They are ignoring the possibility that the RoundUp entered through the roots.

I suspect Henry is right, the severity and non-recovery of any normal growth looks like you won't be able to get back your rose (damage has been done to roots, not just top growth).

The Roundup damage I experienced was only due to drift onto the plant, and not the soil (since I'm in pots) so my roses were able to recover within the month.

Looks like you should probably pull those roses out and replace with other plants, ensuring that herbicides are not in contact at all with the soil and the plant. If you're treating the pavement, it might be seeping into the ground soil? Maybe consider building a raised bed or keeping plants in pots in that area.

You can try and see if they'll recover by moving them to pots, but that would disturb the roots again, and might effectively just kill all signs. Pulling them out will also give you an idea of root health, so if you do decide to do that, could you post pictures?

Good luck!

My roses grafted on multiflora do just fine in our alkaline desert soil. My most problematic roses, as far as chlorosis is concerned, are grafted on Dr Huey. I simply can't tell the difference in my roses' performance when it comes to rootstock. Diane

If you would like both roses on Dr Huey, check out the Edmunds catalog this coming year. They carried both last year and will more then likely carry them this coming year. Now if you want monster bush's, buy two of each and plant them 12' apart from each other, by variety. I like doing this. Makes huge looking bush's. If you're hesitant about this method, just try it with the Queen. I think you might like how they fill in for each other and the amount of flowers you get from a planting like this.

Dear Cynthia,

Thank you again! This is truly very, very helpful. Now that you have pointed it out, I can see that the canes in picture I posted must be coming from multiple roses next to each other, not a single rose plant. I'll have to think about whether to plant another rose or two next spring along my fence or wait and see how this one grows.

Thank you for explaining the difference between primary and lateral canes, too. I have a few primary canes that I plan to tie horizontally in the fall after the leaves fall off (I figure it will be easier to see them clearly without the leaves). Hopefully, the wood will still be pliable. Considering how even a single cane rose like the one in your bottom photo (beautiful!) can put out many blooms, I'm looking forward to seeing how my new dawn develops.

Again, thank you for taking the time to help me out. I really appreciate it.

Best,

Saki

A lot of the brown twiggy growth in your pictures is probably dead stems. IF you have the time to clear that out, treatment of PI will be a lot easier.

I have used several thicknesses of cardboard to protect me from thorns.

And I also sing praises of Tecnu and we go through several bottles of it each year.

Yes, I do have Technu handy..

good point stillanntn. My brain got stuck when seeing PI; yes, I could use some cleaning...

Thanks
