Tree broken at graft union

Posted by ltilton 5 (My Page) on

I thought I saw a branch broken off a tree after a storm, went out, and found my 2 yr old plum tree on the ground, broken off at the graft union. The break didn't look like raw wood at all, it was dark and scabbed over on both the rootstock and the grafted tree. Yet I hadn't noticed anything amiss beforehand.

Is this a common thing? Should I believe I got a badly-grafted tree, or is it just one of those things that happen?

To me that indicates an incompatible graft union. It could be a bad combination of scion and rootstock but is more likely due to a virus infection or similar. Something made the rootstock reject the scion. I've had it happen once.

After hurricane Sandy (ok, the winds were a bit stronger, 50mph) but I lost a Harglow apricot at the graft union. The cut was totally clean the graft must have been weak, but not brown like yours. You must have missed a small sign.

There were no strong winds here, despite forecasts. No branches were broken off on other trees. It's like the graft union just gave up and let go.

I didn't graft this tree, btw, I paid money for it from Raintree.
