The first one was a Winecrisp on G202, it never woke up this spring. It never bloomed in previous years, but struggled to grow. My guess is standing water or high water table was a factor.
The second was a Grimes Golden on G16. It had been severely damaged by rodents or borers so it had about 50% of the rootstock girdled. It produced a few apples last year, and bloomed this year, but couldn’t handle a freak windstorm in April. It snapped off at the base. I should’ve staked it but didn’t, but it may still not lasted more than a couple more years.
I have a couple other trees on G16 and they’re doing well, including another GG.
The Winesap that fell over this weekend was a potted Lowe’s tree. It said ‘semi-dwarf’ on the label, but nothing else, so I have no idea. My guess is maybe M7, but can’t say for sure. It did have significant root suckers, so that’s why I suspect M7. I remember it came from a nursery in TN.
BTW, all of these trees were planted in 2016.
