I made a firm commitment to stop using chemicals in the garden and have gradually lessened my use in so much as the only treatment I used last year and the previous year was Roseclear.  The roses were late to come into leaf this year so decided that now was the time to cease treating them.

However, most of them are suffering from what I think might be some sort of insect problems.  Aphids don't seem to be a problem this year so what is causing the problem and how to treat organically?  Thanks in advance.

    First thoughts are it looks like chemical damage of some sort.
    That said, when one of my climbing roses (a briar) started growth this year all the new shoots and stems were bright yellow and all the leaves were bright yellow and deformed, I don't know why. I've subsequently had the best display ever from it this year.
    Was it possibly over fertilized?
    tbh I've not seen a leaf quite like that before

    Did you possibly give it a spray with roseclear while the sun was on the leaves? - that could well do it

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    It looks very like rose sawfly damage to me Angie.

    I think Ladybird has it in one image  Little be$$ars!  image   

    The first couple of years or so without chemicals can sometimes seem as if things are worse rather than better, as of course the chemicals have depleted the natural predators and they need to re-establish, meanwhile things like saw-flies take advantage of the situation.

    Keep an eye on your roses, pick off the saw fly caterpillars when you see them and hang bird feeders near your roses to encourage blue tits etc into the area ... they'll gobble up the saw fly caterpillars next year if you get them used to feeding around there image

    Thank you one and all.  I used to have feeders out front but removed them so a lesson well learnt!  I've put it back this afternoon and won't be tempted to remove it again!
