This is the graft union of a chestnut on another chestnut done 2 years ago. Does the union look normal or is it indicative of possible rejection. The demarcation is still very obvious which makes me worry the seal is not good.

What a great photograph. Which species is this? Is this a graft between two different species of Chestnut (Castanea spp.)?

That slight gap at the edge of the graft may not be indicative of a problem. There seems to be a good join deeper within. Of course, predicting the long term outocme of a graft is never a certainty. Sometimes even the neatest looking grafts fail, even many years after the joining.

Hope the graft stays! Up to date it seems fine. Although I feel the graft is growing very slowly (maybe that's a good thing since I usually loose the grafts due to breakage from wind or otherwise). Also, this year the graft bore a couple of tiny burrs. Maybe I should have removed those. This is a Marron-type (I do not know the cultivars name) chestnut graft on a seedling with small tasteless nuts. Hopefully, the graft will survive to bear tasty bigger nuts. Thanks for your comments.
