How to solve a problem with my rose

Hi all,

ive grown roses for many year and I am a big fan of David Austin’s. I have their Gertrude Jykell and for the first time ever, the leaves are going brown and dying. How can I cure this? I’ve only ever had black spot in the past. The rose is planted in a brand new border/ garden. My other roses are fine. Picture attached.

thanks for any help.

    I would dig that out and look at the roots. Could it have come into contact with weed killer? Is anything else afflicted? Roses are tough but that doesn’t look good. Hopefully one of our rose experts can help @Marlorena maybe?

    When was it planted?  It looks to me as if it spent winter in a sheltered spot and then was planted out and got hit by sharp frosts.

    Have you had any really cold, drying winds/freezing temperatures lately? Sometimes that can affect young new foliage. Other possible causes may bd if anyone (over the fence?) has been spraying anything noxious, which has carried over and landed on your rose, or if you have over-fertilised too soon. Looks more weather-related to me, but can’t be sure.

    Gertrude is a fairly large, healthy and vigorous rose, so just pick off the dead leaves and she will grow new ones. You have pruned her very low though, are you trying to keep her short? It’s possible she is sulking a bit because of that.

    it was planted last summer. We did have a bad cold spell in February.

    I haven’t pruned the rose, she is the size I planted last summer.

    If the leaves are last year’s ones then it’s perfectly normal for them to dry, especially after all the cold weather in February. Just remove the old leaves and new ones will sprout soon.
  • I was thinking "What's it doing with last year's leaves at all at this season?". My few roses are pretty much leafless, with new shoots just starting. I think I can see healthy reddish shoots starting, so probably nothing to worry about.

    Oh ok, when you said ‘I have GJ and for the first time ever’ I took that as meaning you had had it longer. Don’t dig it up, no need to disturb it, just pick off the leaves, definitely sounds like weather damage if it’s tender new growth, or leaves naturally dying off if old leaves. Either way, don’t worry, it should recover fine.

    ...some points I would add..

    ..the rose looks rather loose in the soil, was it firmly planted? the fact it was put in last summer and hasn't appeared to have grown much, suggests loose planting..
    ..the leaves look like weather damage, and should just be snipped off.. new growth is appearing so it's not dead..

    ..the other thing you should do is to remove those daffodils if you can... Narcissus contain a toxin that is poisonous to roses.. it's called lycorine and it is concentrated in the  bulb...  now I've not experienced problems planting daffs around large established roses, but it is not good practice to have them right near a newly planted rose like that..

    '' All members of the Narcissus family contain the alkaloid poison lycorine. The toxin is concentrated in the plant’s bulb.  You need to avoid planting too close to roses, cabbage, or rice because chemicals released by Narcissus can stunt the growth of these plants''.
