    For future reference, since this post will no doubt come up in someone's seach for RRD info, here is what I just posted on another thread asking about RRD.

    The rule of thumb for diagnosing RRD is for the rose to present THREE symptoms. One symptom alone, it's probably normal. Two symptoms, you watch it. Three or more symptoms, it's probably RRD.

    The symptoms most likely to indicate RRD:

    Witch's broom growth. Once you've seen the real thing, there's no doubt. Although damage from RoundUp can imitate RRD, you can learn to differentiate it. A witch's broom (or several) will have as many as 20-30 buds or stems coming from one point.

    New growth (other than new canes from the base) larger in diameter than the cane or branch it springs from. This will usually have a witches broom, but not always.

    Mis-shapen, red new growth that does not turn green within two weeks. If the growth is red, but of normal shape...it's normal, lol. Red coloration alone is NOT a reliable indicator of RRD. Imagine the leaf in black and white, without any red tint. Is the shape normal for that rose? And red new growth is perfectly normal for many roses.

    Abnormal thorns, both in number and texture. RRD thorns will be much closer together, more numerous, and sometimes much larger, but more often larger mixed with numerous smaller thorns. They may be rubbery, rather than stiff and woody. This is not 100% of the time, but if the thorns do not harden...RRD.

    Mis-shapen sexual parts: pistils/stamens, if the buds open at all. The petals will probably be mis-shapen as well.

    Multiple sprouts from each eye/leaf bud. With RRD all the dormant "extra" buds tend to sprout at once.

    Extremely rapid growth of just one part of the rose (this does NOT include new canes coming from the base unless they exhibit at least two other symptoms).


    EDIT: if you ever need a hard and fast diagnosis, @stillanntn6b. She is THE authority on the forums (and anywhere else, for that matter, lol) on RRD. I hate to make more work for her, but she really is the best.

    Healthy, normal growth....your apprehension is understandable. I was hit with Rose Rosette Virus last year for the first time, and I was demoralized like I've not been in a long time. Digging out the diseased roserose was heart breaking... but life goes on.

    Thank you all for commenting! I am a rose newbie, and I went a little nuts and have planted 16 roses this year alone. Hopefully my garden will look as beautiful as all of the ones I’ve seen here!
