Buried my graft union.
This is more of a story than a question.
About 5 or 6 years ago I planted two apple trees. I planted them only because I bought a new house with a big yard and planted a little of everything.
I have since become a Novice Orchardist and have planted 12 more apples with my selection of variety and rootstock.
I learned about rootstock/graft unions, etc. The new ones are planted correctly.
I just noticed the other day that there is no visible graft union on the two original trees.. Either they never had one or more likley I planted it too deep!
Anyway they are now 11' tall and about as tall as I want them. I guess that I'll just keep pruning them?
