This is what a tree graft failure looks like on a Japanese maple.
Some beginner gardeners might have blamed a rodent for eating away at the bark but it’s really a problem with a graft that’s beginning to fail and kill the tree after (about) 8 years in the ground.
Can It Be Fixed?
Technically yes – if you were an expert grafter, you might be able to graft multiple shoots from the root to the tree and bypass the failure point. I’m not.
But realistically – unfortunately, no. This tree is simply slowly dying from the top down and I’ll be pruning off the dead branches over the next few years (at least I hope I have another few years) 🙂
Isn’t There A Plant Guarantee?
If this had happened in the first year or two, then yes, you could ask for a refund.
This tree is 8-ish years old in our garden. Any warranty has long expired.
