I have had several semi dwarf apple trees that were purchased from a major nursery and they all failed.
They normally last a few years and either break off where they were grafted or just fall over, this year they all fell.
Earlier I had them staked with the orange screw in tent stakes but they didn’t work so I cut some 2x4s.
I was going to drive the stakes in then drill the holes to avoid breaking the stakes but it was a day of failure, my cordless drill wouldn’t turn the bit even though it had before and my corded drill wouldn’t let me tighten the chuck even though it turned.
Ended up using a hand drill which was a pain horizontally that close to the ground.
Staking trees generally isn’t very good for them because it doesn’t encourage strong root growth since the tree doesn’t have to hold itself up but if I ever bought Apple trees again I would stake them and just accept that they will always be staked.
I am going to try to grow some trees that aren’t grafted from cuttings and see how they do.
