Tebuconazole (Bayer) ... propiconazole (Banner Maxx) ... everything else that's said is just hysterics, IMHO. They're among the most inoffensive chemicals around. The stuff is even used in shampoos to prevent dandruff - Nizoral (ketaconazole).

Bayer advanced is very effective. Picture has nothing to do with anything. I just like to show off.

Sometimes you just get a dud plant. I've seen this in a few beds where I've done mutiple plantings of the same rose. Same bed, same light conditions, same soil and treatment and they just refuse to flourish even though the other 4 or 5 of the same variety do just fine. It happens.

In my experience, if it's a long-term problem, there's something in that hole that you missed - a rock, etc., that's blocking the roots.

If it's something else, then what others have recommended may work. Be sure it gets at least 6 hrs of sunlight. Build up a 3-4 ft diameter drip ring with mulch (I like shredded pine bark mulch), and feed it organics - my organic of choice is Mills Magic Mix.

If none of that works, there's something in that hole.

Thanks for the recommendations.

I get conflicting information on Fru Dagmar. A local nursery and some websites say it just flowers once, in the spring. Other websites say it flowers throughout the summer. What is your experience with this?

Frau Dagmar flowers very heavily in spring, but also repeats well all season and very well if dead headed. If not, she also sets beautiful red and large hips that add fall and winter interest. She's a beautiful rose and one of my favorite Rugosas.

As far as I know, they have retired.... don't know if someone else has the business. I found them easy to contact and was really happy with their service..... perhaps you have tried to contact them since they retired.... it is too bad they are gone! I tried to propagate Island pearl from cuttings.... in a very slap happy fashion, and so far one is all that is left!

I know this is an older post, but thought I would respond anyway. I just bought an Island Pearl Rose from Milner Gardens. They have an ongoing plant sale of unique, high-quality plants.

I had a JFK that I shovel pruned after 4 years. it was always soooo promising. excelent growth, long canes, no black spot (only mildew when the damp ocean air sticks around too long), and HUGE HUGE HUGE flower buds which never opened all the way because I think it is too moist and/or cool so close to the ocean.
I gave up and swore off white roses. :)

Still no good after 6 yr. trying everything! Shovel pruned was the best thing I did for it. And I do know how to take care of roses, thanks to this forum! Will never try it again.

I did go to helpmefind, but everyone on their list seems to be out of this rose at this time...

Thank you deervssteve, I'll try rosesofyesterday...

I really wouldn't want anything shipped until Fall, so will keep my eye out for this rose, it sounds great for our area!

Have you contacted K&M Nursery or Coolroses?? I grew St Patrick in FL. It was a huge workhorse for me. By the time it was 4 yrs old it was putting out 35/40 blooms per bloom cycle. It's on my list for next spring.

Thank you, Donald. Looked it up on HMF. The exact same characteristics.

You're most welcome. Dortmund is a beautiful thing. I hope you have lots of room; this is what Dortmund can do, here on the west coast anyway.

Oops...here he is.

The leaves show some minor early infection of blackspot. They also have some whitefly damage and it looks like a rose slug larvae may also have been chewing on some of the leaves. None of it terribly serious.

You should have just left the foilage on the plant as even damaged leaves still provide energy to the rose. It will shed them itself when the leaf is no longer viable.

Those are really pretty flowers. Some rose bushes hold their flowers longer than others, and this one may be just a bush that lets its flowers go pretty quick after they open.

The only thing to do now is wait and see how it does after losing so many leaves. I think it will come back, but keep an eye on it for new growth. Keep it watered, how much depends on whether it is in direct sun or not and your daily temps. Roses do best in direct sun.

Not sure about that wire holding it up. If it's an important wire, you might want to get a narrow trellis to support the bush and get it away from the wire.

Good luck.
