Hi,
Some of my blooms on a particular rose shrub have slight browning on the ouside petals. Plant generally looks very healthy and it ia just the outer petals. Any ideas? Thanks.

last month@floral_uk z.8/9 SW UK thanks. No aphids but looking between the back petals and behind them there is coloured spotting which is strange. The flowers should be plain pink (Chandos Beauty rose) so shouldhn‘t have these dark speckles. Any ideas from these pictures? Centre of the rose is perfect just on these outer petals. Thanks.

Which Roses Do Not Drop Petals?
Comments (22)Yes, I'd agree that the degree to which a rose hangs onto its petals is more a matter of petal structure and genetics of the rose than the type of rose per se. Stiff, high substance petals (like Dream Come True) can last in their bloom form until the whole bloom falls apart and that can be several days. Anything that is considered good for cutting or a "florist" or "exhibition" rose tends to hang onto its petals longer than those that do not. While more HTs are considered florist roses than other types, that doesn't necessarily mean that HTs as a class are better at hanging onto their petals in general - it's just because the buying public expects that form in their cut roses. One of the most lasting blooms I can think of is Acropolis, which I think is a shrub. Still, the blooms stay on the bush forever and eventually age to a very pleasant parchment tone of pink after maybe 10 days. If you're looking for roses that don't blow quickly you really just have to check around within the types of roses. Like everything else in rose growing (e.g. black spot resistance, bloom frequently), blowing quickly varies a lot among roses within a certain class. Some subtypes of roses like Austins have a reputation for blowing quickly, but as mentioned above they were bred for this so that's not surprising. Even among these, I find that Austins like Molineux or Darcey Bussell hang onto their petals pretty well, at least average times. Cynthia...See MoreWhat causes brown petal edges on light pink rose?
Comments (3)Hi Lux, thrips can cause petal edges to brown because they suck out the sap. They LOVE lighter colored roses, particularly those with thin, papery, fragrant petals/blooms, which both Lemon Spice and Sunday Lemonade both have. Excessive heat, low humidity, intense direct sun, too much salt in the water (either naturally occurring or added fertilizers) can also do it. You can easily check for thrips by pulling open the petals and looking for small, thin insects between them. Perhaps a hand held magnifying glass or even the macro of your camera might help you see them. You may also consider if any of the other conditions mentioned above might fit the situation.

Comments (2)I have had a Bewitched for over 10 years. It's absolutely gorgeous in Spring and late Fall. In between, it pretty much goes dormant in the heat. It does not like heat, period. Let me emphasize that - very few roses, if any, have I seen that go totally in the tank during summer heat, but Bewitched does. I agree with seil that the current climate this summer has been hot enough to burn almost every bloom. That may be all it is....See MoreIan Thorpe - brown rose
Comments (17)Dee & Annie I'm sorry the pic didn't quite come out as brown as it really is in realy life. It is the closest to Leonidas in colouring I've seen - truly. My Ian T still has much leaves on it and as far as I can see - no PM. However - as none of my other roses around it has PM - I would imagine that given another season and time - it would succumb to PM like some of my other roses - I'd have to succumb to the spraygun. I've tried to fiddle with the colouring here to give a better impression .......See MoreAlfie
