Problems on my roses..

One thing I have discovered in my short trip since starting gardening is that i'm never more than one step away from an issue :)

The two pics are of a couple of my roses, leaves browning and dying etc - any suggestions as where i start my recovery research?

Many thanks

    They look thirsty to me ,also if they are in the ground I would take that shingle slate away as it can hamper their growth ,I found that out myself the hard way .I would try giving the roses a jolly good douse with water ,wash up water will do if your in a water shortage area ,or bath water .That should help .You can gently remove the brown leaves if you like ,they won’t green up now , but you have plenty of chance to revive them Don’t water till the evening or at least in a bit of shade later on .

    Various issues going on there but one thing I'd say you do have is rose rust, quite a severe case.
    You should defoliate your rose, just snip them off with scissors, discard all leaves, and you might want to consider spraying with rose rust prevention.  I don't spray so cannot recommend a product in particular but there are lots out there.

    Thanks,

    They are on an irrigation system, and are growing in large pots. The soil seems to be fairly damp but I can increase watering if needed. They get watered twice daily 6am and 6pm at soil level. Its based on temperatures at present and todays volume is 2.1ltr (3.7pints)at each watering.

    I'll trim off and look at some rust treatment ASAP.

    Thanks

    Ok, i've defoliated pretty severely, hopefully enough, got rid of all debris in bin and washed my secateurs. Then i treated with Rose Clear which listed rust as one of its targets.

    Fingers crossed that will get a grip on it. I'll give them all a feed tomorrow evening.

    Is rust something that just happens or would it have come in on a new rose etc?

    Some roses are susceptible to it but most are fairly resistant these days.  I see little of it on mine, just a leaf here and there and I've never seen anything like that.   I notice you are in a hot part of the country so there could be weather induced problems on your rose as well.  It's not only rust, there appears to have been a complete breakdown..
    However, you might start a spray regime next Spring and see how it goes.  If I had a rose that looked like that repeatedly,  I'm afraid it would be disposed of and something better in its place.  This is up to you to consider perhaps..

    @DaveKearley I cut my rose down 2 weeks ago after it had not one single bud and now it starts again to get fresh new leaves. 
    We have a rose in front of the house and it was in a really sorrow stage. I cut it down 6 weeks ago and it’s flowering a lot and looks so healthy. 

    I ♥ my garden.

    @DaveKearley I always think the best wat to water any plant in a pot is to soak until you see some water running out the bottom. This isn't instant, so water and wait, may be go to the next pot return to check it has come through.

    Thats pretty much how i set the volume of water for the setup - its also applied in 5min steps so 5 on and 5 off - this is to allow the water to soak in and not just run straight through and out, seems to work ok.

    Yes, very hot here and they are in sun most of the day too. Its not been like it all along but now i think of it I recall seeing some black spots on one rose early this year but not thinking much more about it just left it, maybe it spread from there ?

    I'll see what happens next season I think, maybe a hard cutting back in winter will help refresh it.

    Its early days yet I guess but things are not improving :( The remnants of the defoliated rose are getting worse, I now have signs on a Peony and it has spread to one of my newly purchased climbing roses on the other side of the garden now.

    My guess is to wait for winter and cut them right back ? 

    I did try to treat the undersides of the leaves with the Rose Clear stuff but being a hand-held gun means it stops spraying when inverted - is there a better way?

    And there was me thinking gardening would be stress free  ;)
