Roses

We bought and planted six David Austin Roses in February this year and planted them in our garden.  At first everything went well, with the plants growing and seemingly establishing.  However, the leaves on four of them have now turned blacky brown and the plants look awful.  We've fed and watered them regularly, and we enriched the ground before planting them.  We have good drainage and there is no root rock.  Any suggestions other than digging them out and burning them?

  • could be fungal issue? I had rust and some back spot via some DA Roses. Rose Clear seemed to sort it once the infected leaves where removed.  I'm not an expert on roses but presume once they go deciduous most of the fungal spores go with the disposed of leaves?

    Excellent advice from waterbutts.  Additionally, you should be meticulous about clearing the fallen leaves from beneath the bushes and always burn or bin them - don't put them on the compost heap.  Each Spring, put down a fresh layer of compost or manure under the bushes which will both feed them and cover any fungal spores which will be on the surface of the soil.

    If you plant any more roses in the future, it would be wise to look for blackspot resistant varieties now that you know your area is susceptible to the disease.

    A trowel in the hand is worth a thousand lost under a bush.
  • Thanks to all.  I've seen blackspot before but this literally looks like the whole plant has been infected with something and gone completely discoloured.  We were  warned that roses don't do well here in Somerset before we planted them,  but decided we love roses enough to have a go.  However, I will attend to the plants and see what happens.

  • Why not send an email to David Austin customer services to ask for their advice, it may be something that is known to that certain rose and they may give you advice.

  • Hi can you please tell me why the leaves on my roses,apples,and pears get brown spots turn yellow then drop off, still get lots of roses and fruit. This happens every year. Thankyou  Anne Baines.

    I put a post on here about my David Austin roses yesterday, good idea to ask their customer services. I'm going to send my photos in later.
