What is the best rootstock for apples planted in wet areas for Zone 5A?

Way more than me. I just dug the hole, triple mix mound on top. Plant tree. Mulch on top. 4 years later adding 2 bags shrimp compose and replacing mulch.

Grow or die! Working so far.

That’s great! Must’ve been strong stock!

Sorry, also forgot I have a plum also on Marianna 26-24 in same wet situation that is doing great as well so far.

Me, too. But newly planted.
