I cut out the dead wood and found black stains in the sapwood, so cut back all the way to the point I could no longer find any staining - thinking it was some sort of canker or some such. I've now come to the conclusion it's verticillium wilt.

All the leaves just suddenly went brown and crispy for no apparent reason.

It's just self pruning to protect itself. A lot of plants in the sumac family (Anacardiaceae) do this.Then after it drops it leaves, cut it back some more so next year it doesn't outgrow its water. Mine does this crinkling at the top, too, near the end of the season. I love this tree, too. I first saw it in Cambridge Botanic Garden in the 1980s and when I got home to southern California, I had a long search to find one but eventually did.Jane Stronghttps://www.blogger.com/profile/05016381279699618539noreply@blogger.comtag:blogger.com,1999:blog-3840827850297141825.post-74596278579217694002014-10-02T18:35:43.586+01:002014-10-02T18:35:43.586+01:00Hi Gill; OK then, I'll follow suit...Hi Gill; OK then, I'll follow suit...Mark Willishttps://www.blogger.com/profile/04558305122821209520noreply@blogger.comtag:blogger.com,1999:blog-3840827850297141825.post-28952953318896344122014-10-02T18:35:00.793+01:002014-10-02T18:35:00.793+01:00Thanks Roger.

It is sometimes difficult to know that a pathogen was able to invade because of these physical things.<br />Last year I lost a large cotinus- nearly a metre high with sudden death at this time of the year.<br />It had been given me as large container grown plant the previous Spring and of course I was aware it would need occasional heavy watering that Summer. It seemed to be thriving and then, bingo it was showing exactly the same symptoms as yours!. I wondered if I had relaxed my watering too soon in a dry Autumn!<br /> Roger Brook - No Dig Gardenerhttps://www.blogger.com/profile/16210160273591839142noreply@blogger.comtag:blogger.com,1999:blog-3840827850297141825.post-10339804043592399312014-10-02T16:29:44.118+01:002014-10-02T16:29:44.118+01:00I tried layering my Cotinus "Grace", and...I tried layering my Cotinus "Grace", and so wounded a stem before burying it.
