Lainey,
I haven't heard that about NJ and I doubt it (as RRD really doesn't lend itself to spraying.)
There is a plant disease note for Maryland where two scientists announced that they had successfully gotten RRD to take in Maryland by graft augmentation. To my hypersensitive reading, they were really pleased with what they had done.
Sometimes when you plant a rose the roots get damaged, and cannot support the top growth, and it dies. To prevent this, I would immediately prune back your rose to maybe 12 inches high. Take off all of the blooms and buds - they will be replaced if it survives. After you have pruned it down to a small size, DO NOT feed it - just make sure it has lots of water (which it needs temporarily because of lack of roots) and good drainage - that is very important. If it survives, it will just sit there for a while (weeks) looking like it is not doing anything. It is actually growing roots under the dirt, which you cannot see. Then it will start to sprout leaf buds, and eventually flower buds, and away you go.

I'm surprised to hear of vigor issues with this rose. I cut mine back to around 2 ft every winter, and by end of growing season, it's always back to at least 6 ft with many new canes (picture is from early August and that's a 6 ft fence behind it). It also has very little blackspot here in our humidity even without spraying. I believe mine is grafted on Dr. Huey, but I can't remember...some of my roses in the "Easy" group are own root and some grafted, but all are very vigorous here.
It typically take a rose 3 years to establish, but it depends on the variety. Some grow roots first, then top growth. The phrase is: First year sleep, second year creep, third year leap. If the canes are still green, that is a good sign!
If it was a soft new bud that broke off at its' base from the cane or from the bud union then it wont regenerate from the same place. Guard buds spring from a growing cane that is cut off in the growing region where there are meristematic cells. From one you will get two. BTW, if you break off a sucker at its' base it wont regenerate but if you cut it off above the base you may get two suckers.
I have newly planted a own root blushing iceberg. But 2 days after potting, many of its leaves have turned yellow. Some of the buds are dropping too. We have enough warmth here in tropics even during this part of the year, so that is not the problem. I have ensured that i am not over/ nder watering the plant. What else could be the reason...Remedy?????
Paul Zimmerman does some excellent rose pruning videos.
I live in Houston and we always advise to prune the week of V-day.
As for spraying I usually hold off until the roses tell me. Temperature and humidity are great right now for BS but we are about to dip into the 40s this weekend which should help. When the weather is 50-80 degrees with high humidity I worry about spraying.

Will do and thanks a bunch Kim.
The rest of my babies are doing so well I could just cry....well I tend to blubber easy anyway.
I have noticed that the plants that lost a noticeable number of leaves this winter(?), are generally producing more leaf sprouts than the ones (Pristine and Sterling Silver) that lost almost none. Each one seems to have it's own personality and growing habit. It's really interesting to watch.
Lady Emma has had 3 large blooms, Molineux has large buds ready to pop, and they are all just generally looking like SPRING HAS SPRUNG!!
I have already fertilized once, foliar sprayed 2 weeks later with Neptune's Harvest (Fish and Seaweed), and cleaned up the beds and put down a spring layer of compost this week end.
I'm just so happy to be out playing with the babies....
Hugs and Smooches,

Very interesting. It's a determined little bush. I got my first GP last spring and really enjoyed it during the summer. After only one year in the ground, I moved it this week to a place where it will get more water. I had to hand water it last year, and since we're in a drought, I'm gearing up for reduced water.
Disbudding is more critical for small, newly rooted cuttings.
A grafted or even an own-root body-bag rose has been growing for 18-24 months, so it's not so critical to disbud.
Also you have a long (51 week) growing season. A short growing season means there's less time for the plant to establish. A long one means it has a lot more time.
Expect your newly planted roses to slow way down in the heat of summer. In future years they will handle the SFV heat better than they will the first year.
Roses Unlimited has Dee Lish listed as a new rose this spring. Their roses are one gallon size own root roses.

Hmmm...a friend gave me Dee-lish last fall along with a couple others he'd gotten (he knows people and gets early releases he shares sometimes). At the time I wasn't all that thrilled with it but it was free so I accepted it (I'm known for taking in strays, lol). Now I think I might be glad I did (could become rare)...or maybe not depending on why it failed, lol?
Thanks, Henry
