I planted a couple of new blueberry bushes... In the fall and winter they get 3 hours or less of sunlight.
In the spring and summer months they should get a full day of sun light.

Anyone see a problem with this? I can move them but would rather keep them where they are.

Sounds good. Make sure they get enough water. They are from New England and they aren't used to hot dry summers like we get here in the PNW>

That amount of sunlight should be just fine. I have 6 blueberry bushes, all different cultivars and all are thriving, despite the fact that my soil is a terrible clay and I have no idea what the pH level is. People always advise you to make sure to give your blueberries plenty of acidic fertilizer or they won't do well, but unless I've gotten extremely lucky, I'd say that recommendation is a little overblown. They also say you need well drained soil (what doesn't?) but like I said, I have clay other than the topsoil I planted them in. I think they're tougher than most people give them credit for.

So no sun in the fall and winter should be OK?

Yes. They get only a little in New England in fall or winter. Mine have done fine with very little in fall or winter.
