    @Marlorena That is really useful GdF info that I will follow, thank you

    @poppyfield64 Seeing as I recently mentioned a rain resistance filter I wonder if that is what you meant? I was referring to Agel Rosen website where the filter is in the german bit they haven't translated. Expand "Rosen nach Eigenschaften" (Roses by characteristics) on the left, there you'll find what you want "Regenfeste Rosen". And if you want to see all the roses not just those in stock  there is a box for that under filters

    @Marlorena thank you from me too for the pruning info on GdeF.

    And thank you @Tack.  I found it now......I was on the wrong website lol.  I do like the look of Leonardo da Vinci for the rain resistance and have seen a few others I like too.  Best stop looking now as have so many google pages open, I don't think my old laptop can cope!!

    Thank you so much @Marlorena. Your advice is so helpful. I'll definitely follow that advice later on. And will snip the errant leaf on English Miss. 

    I'm assuming that if I dig up the two blackspot prone roses, the fungus will be in the soil. Would planting an ADR, super disease resistant rose in the same position limit the likelihood of black spot affecting them? Or should I treat those area as in quarantine for a period of time?

    @Katsa Blackspot spores usually overwinter on rose stems and fallen leaves. It doesn't live long in the soil. Even if it survives in the soil, if you mulch with a layer of fresh compost or other mulch, they have no way how to get on the leaves of the new rose. To be 100% sure, you could also do a sulphur dormant spray (I plan to do it this winter to see if it makes a difference).
    If you plant a disease resistant rose, it will be most probably fine. My Joie de Vivre is right next to infected roses and doesn't get it.
    I would be more worried about rose replant disease than blackspot.

    @Katsa
    ...this isn't something I would worry about at all... if you see any remains of black spotty foliage lying around, then you could remove it, but otherwise it's not something worth bothering about.. just replant your new rose...  you might want to add some amendments though.. I have found replant disease can occur even after just a few months, contrary to what you may have read..  but it doesn't last long, but the new rose can receive a check in growth.. it helps considerably if you can replant just a foot or so to one side, of the original hole...

    As for ADR roses, I have 2 here at the moment and they are amongst the best for disease resistance, but that does not mean their blooms are always the best.. they may suffer in our climate where humidity levels are often high..
    .. so it does not always follow that ADR winners will be perfect here.. they are tested under German conditions.. black spot fungus has many strains, and they are different not only in other countries, but year on year... however, you should feel more confident with these in the main, so I recommend them as first choice if available..

    My preference when ordering from abroad is to go for roses that are listed as having a strong fragrance.. they may not be the most disease resistant, but I do want scent..

    @poppyfield64
    ..your Hansa is very nice.. not one I've grown before..
    ...the yellow and orange roses being more susceptible isn't something I would take a lot of notice of...  what one often finds is that highly scented roses have poor resistance... roses without any, or little scent are often almost disease free..
    ...I understand that on the rose genome, the genes that confer scent sit next to the ones that produce immunity to diseases and one over rides the other... so you get disease free scentless roses and strongly fragrant disease ridden beauties..   the difficulty for breeders is to produce the exception that provides both disease resistance and scent in one rose.. 
    David Austin plays the numbers game, producing some 200,000 seedlings in the hope that just two or three will fit that bill..

    ...you have a number of lovely roses there.. it would be good to know the names of them at some point, as otherwise we don't know what we're looking at... and I especially would like to know the rose in photo no. 3.. and the last one,  thanks..

    I've posted a photo of my "Lady of the Lake" a DA short rambler. I'm really happy with everything about it, it's performed beautifully all Summer (plenty of blooms out of picture) but the problem I've got is the criss crossing growth of the stems, it doesn't look good, rather messy and untidy quite frankly. What would be your advice on how to improve the appearance for next year. It does flower on new growth so major pruning might be an option with the possibility of training it again from scratch...or just hide it with a clematis.
