I bought two 5 in 1 apple tree from theusanursery.com which I now fear is just a relaunched summerstone nursery that had a horrible reputation. Seeing as how these trees are supposed to be 5 varieties from the same tree, I expected at least 5 branches grafted on to a trunk. Instead what I got was a 2.5' twig grafted on to some roots. Since it's one twig with no branches am I correct in thinking there's no way there is more than one variety of apple tree on this plant?
