I also wanted to chat here about the prevalence of blackspot on BV and HC.
So far, both BV and HC get blackspot here, actually HC was covered in BS when I first got it, but the trouble setteld with a regime of mulching and removing all the affected leaves. So far BV seems to only get blackspot on the occasional lower leaves.
I am now starting to prophylactically remove these basal leaves even before they show blackspot. Is this practice a bad idea?!
oh…I should say that I never spray the roses with anything at all.
I spray all of my roses with love <3
haha.
Seriously, BV and HC dont blackspot here despite being blackspot central.
You are very lucky, Jadae
Actually, there are very very few roses I can say dont get BS around here, it is a matter of how much BS they do get.
I must get a ‘R. Wuichurana’ specimen soon, to see if it gets BS or not here.
I have seen some sort of leaf spotting on ‘R. Bracteata’ specimens here, but I am not 100% sure of the pathogen. It might not be a blackspot, and in any case it is very minimal, maybe it is just expired leaves yellowing and about to drop.
Well, I imagine the blackspot here is similar to the blackspot in the UK. Being as Hot Chocolate comes from Livin Easy, a UK bred rose, it doesn’t surprise me that it is healthier here. A lot of UK bred roses, be it Harkness, Warner, Scrivens, Cocker or Dickson, do very well here. A lot of McGredy roses, with some major exceptions, do very well here, too. The west side of Oregon and Washington seem to be similar to the UK (and I am guessing Japan, too).
I was not very fond of R. bracteata as a species here. Personally, I am going to stay away from it as best as possible. But a lot of others seem to love it. To each their own. But, yes, I also saw spotting on it. It almost looked like anthracnose lol. It wasnt mildew or blackspot, however.
lol…when I first saw a mature ‘R. Bracteata’, Jadae, I thought of Jurassic Park, especially those gigantic triangular prickles that it had sticking out the “tree stump” it had developed…well, they reminded me of those triangular humps that poke out of the back fo some dinosaur types.
I actually do love the smell of its pollen, it is quite unrose like?! and the flowers are intriguing, but I really dont care for the gigantic growth and excessive and hooked prickles…OUCH!!
UPDATE ON ‘BROWN VELVET’…
Similar to Robert-N-R’s exepriences with ‘Brown Velvet’, one of my three ‘Brown Velvet’ plants got beautiful foliage, then declined with a global mildew attack, which was quite unsightly. I shovel pruned it, yes it was that bad.
The lucky /interesting thing is that the other two plants of ‘Brown Velvet’ I had acquired from the same grower were positioned in a totally different aspect of the garden, and they are NOT showing any mildew attack.
If they do mildew I plan to still keep them, unless the attack is global.
How weird it that!
Location makes a big difference in terms of mildew.
Areas with restricted air flow experience worst symptoms.
Yeah, Robert.
The two ok plants are located in a corridor at the back of the premises, maybe there is better ariflow in the corridor (if so this is pure luck for me).
My backyard and propagation areas are surrounded by high block wall. This sets up an ideal situation for testing for mildew susceptibility. I’m glad when it shows itself. At lest I know what I’m working with.
My front yard gets lots of air flow so no excuses for anything placed there.
The more I hybridize the less I want to waste my time on parents that produce disease prone offspring. No roses is ever going to be perfect but some are much better than others.
I have actually always had a very low tolerance to mildewing roses. I don’t think about mildew much, because the roses I am used to seeing in suburbia here are mostly varieties that are immune to mildew in the outdoor garden setting. So whenever I SEE mildew (eg. laevigata-big time, fortuniana-to a small extent, some teas etc etc), it really gets to me…now that I think about it I probably get more upset when I see mildew than blackspot-which is pretty much everywhere here.
This could turn out to be a great climate for testing roses against theses fungal afflictions, I say … :0)
My ten Ebb Tide X Hot Cocoa seedlings have flowered. The flowers were all doubles, but were so small, and alot of them showed this central vegetation thing in the flowers. I kept none of them.
I’ve removed Hot Cocoa form my breeding plans.
Oh I forgot, there was one single, it looked like a really inferior version of Ebb Tide.
Thats a shame, George. Sometimes you hit upon a combination that is just all wrong and the genetics go south. At least now you know!
FWIW, ‘Hot Cocoa’ might not be solely responsible for the glaring defects, it could easily be both parents.
