As a newbe here can anyone suggest why most of my roses have their new shoots damaged. I tried a bug spray, slug bait, and ant killer to kill green aphids  Thanks

    Damaged in what way? 

    That's a lot of chemicals. Have a thought for any wildlife in the garden

    Thanks . The leaves on  one Rose look are all stringy and look as if something tries to eat them. Likewise any new shoots. I have pruned most at the back garden down to just a few inches hoping new shots will survive.

    You need to show close-ups of the damaged roses to get any real help but do, please, put away the chemicals and concentrate on feeding the soil and the roses so they can grow as healthily as possible.  Then they can fight off diseases and the good guys can come along and eat any pests such as aphids.

    Have you recently moved to this garden?  The soil around your roses looks very poor and sour ... signs of moss and algae on the soil and rose stump and blackspot on the leaves and stems.

    The young growth may well have been damaged by the over-application of spray, particularly in bright sunlight.

    The soil in this garden needs lots of mulching with organic matter to get it back into good heart.

    I agree.  Leave the roses alone and get the soil in good heart.  No use trying to cure ills while the roses are struggling for nutrients.

    your roses look quite old. If sorting the soil out for next year does not work it may be time to start thinking about getting some new stock.

    Thanks but I no longer run a compost heap at my age of 83 I have a hard working gardner to cut the lawns and hedges. What can I buy for compost I assume you do not like Growmore fertilizer.

    All but one of the roses have been here since 1995.

    I would buy in some bags of rotted farmyard manure from the garden centre.

    Growmore is a chemical product that may provide nitrogen, potassium and phosphate to your plants i the short term but will do nothing to improve your soil or help with micro-organisms that are beneficial to both soil and plants.   You need to apply a couple of inches depth of well-rotted manure to all the bare soil but make sure you do it after decent rainfall or you'll just lock in dryness.  

    Do it every autumn too when herbaceous perennials have died back and then bung a bit more round your roses every spring.   Your soil will improve no end and so will your roses and other plants.
