Kim's method works for me usually. Fire up that chain saw and look at the avo tree....first time that thing ever produced a fruit (but the fruit was bad so it still met the firewood pile)
St Patrick and QE have had the shovel waved at them this week. QE will loose her head first I think.
Leena, yup, that is rust. What I would do is:
1) Remove every single leaf which has those spots on it (they contain spores, and can spread to other roses) carefully - they make spore "dust" which floats all over the place. What I do is hold a brown paper bag under them so that they drop directly into it. Close the bag and dispose of it in the garbage, not your compost bin.
2) Spray the bush with a fungicide only spray (not 3 in 1,2 in 1, anything that contains food, etc - just a fungicide). Of course, follow the directions.
3) Keep watching for more rust, and repeat the above. You can and will get control of it. It can spread, as I said, to nearby roses if you don't actually remove the spore infested leaves.
Good Luck -

You can even use your computer to tell you when to spray (it doesn't sound like it would be much of a stretch to have the computer turn the sprayer on and off!

Egad, you're right Kim. Just picture the mayhem if you had to run out into the street yelling - "help, the coyotes just carried off my Blessed Child". Much as we love our roses, I don't think the neighbors (or police) would understand.

My Prospero has only one flower bud on it today, but that bud does not have long, leafy sepals. Overdeveloped sepals (for the variety) are one symptom of RRD, not necessarily definitive. I would remove the shoot and keep an eye on the little guy (one of my favorites too).
You should scout the neighborhood for infected multiflora and garden roses.
I think Henry is justified in suspecting herbicide could be involved in a "whole bed" of mini roses showing strange growth. RRD would do that only if symptoms were ignored for a couple of seasons.
Hi michaelg, Thanks so much for looking at your Prosper. I cut that branch way back and have another bud that looks strange with the long sepal. I am going to let it grow for a few days and take another picture. I have a row of 5 Prospero and the 2 on one end look strange.
I think the bed of mini roses could have been round up damage. I don't miss them as much because it hurt my back to bend over.
Appreciate all the help.

Incidentally I remember reading that the common reddish "lava rock" is actually a brick-like by-product of some industry--I just can't remember what. Steel, maybe. Not that it matters, but I always wondered how it was harvested or mined and where it came from. Not volcanoes, as it turned out.
I read the following on another post - sure hope this works out, I have missed Pickering!
Just an update on the Pickering situation..... I called Pickering 2 or 3 months ago, but don't think I posted what I learned on GW. Sorry about that. Anyway I called because I'd ordered roses from them to be shipped to friends of mine in Canada as a gift. This was to at least semi-replace my order that they couldn't ship to me in California. While I was on the phone, I asked about the future possibility of those of us in the USA getting their roses shipped to us. I was told they expect to begin shipping to the U! SA again this fall, and if I understood correctly, this coming season will be the last one for them selling grafted plants. After that they are going own-root. I didn't ask if they still planned to sell roses bareroot or if they'd be potted (or the size if they go this route).
It's possible it could be your new roses were overfertilized
from the miracle grow and that caused the problem...
And the MG soil you added around rose roots probably also had fertilizer added in to it.
What do you others think???
You may want to try using mulch around that rose
since the soil is drying and cracking...

Michael, a lot of these roses seem to have several names - Millie has also been Ghita and Mum in a Million, Claire has also been Liliana, Eleanor has been something else which I cannot recall, Philippa seems to have vanished off the radar but is probably just using a different name........so Clara may well be known by another name altogether.
I have my own name for them - Irritating Eyesore.
If only my Memorial Day could look like yours, Susan. Mine always has thrips damage and simply can't take our heat. Maybe things will get better in a year or two. It didn't help to transplant her this spring either. Anyway, your photo is gorgeous and that look of pink porcelain was one of the reasons I bought MD in the first place. Thanks for posting your photo. Diane
When I lived in that area, many roses defoliated during the worst heat of July & August. I kept up the watering, fed them at the beginning of Sept. & enjoyed a new flush of leaves & blooms when the weather moderated. Usually, in September, the nights start to get cooler & give the plants some relief.
Fall blooms were often the best of the year in that climate. And once the roses recovered they were beautiful into December.
Defoliation is the plant shutting down because of stressful adverse conditions. Sometimes it's only one stress that causes it, but more usually it is a combination.
So for example, a rose being stressed by a lack of water will not need much pressure from black spot to start shutting down. Similarly, a rose stressed by an untreated black spot infection will not need much pressure from a lack of water to start shutting down.
Unfortunately, if the shut down continues for too long it can be fatal. Roses and other plants are not immortal, and they do die if conditions are adverse enough.
Hmmm....that does not sound good. :)
Since all of my roses are in pots - they need to be stand alone roses.
I know someone whose garden it will look fantastic in. I think I'll give it to her.
Thanks!

Good Idea....and well done for looking further than your usual choices - those are the times when serendipity strikes and offers up lovely surprises - all the better after taking a bit of a risk.
