Ning planting 2 apricot trees

Neighbor had 2 seedling apricot trees they've been growing for a number of years. They wanted to give them away, so here we are! Nice neighbors! There is some risk - first, I've never been able to get an apricot tree to survive here. Second, seed-grown, no idea what the apricots will be like. Finally, they might need a pollinator. Still for #2, my neighbor has had these outside for maybe 6 years, in containers. I suspect they will be OK. Maybe there is a rootstock issue with the trees that have died? These are seed grown, so on their own roots. As for pollinator, since these are seed-grown, each should be genetically a little different from the other, so they should be compatible. As for the unknowns, we have room for them, and there isn't much risk, so here they are. This little orchard now has the 2 apricot trees, 2 pear trees, and an American linden (nectar source). Also planned are the 2 dwarf apples I bench-grafted at the Home Orchard Society grafting class, starting to grow. I'll keep then in containers for a little longer before planting in ground.
