Planted 4 trees yesterday...how big should root ball be?

I think those were just nutrients to keep the plant healthy while it was in the container. Doubtful they would put root stimulator while its potted in the nursery. We just planted two red Maples yesterday and plan to follow up today with root stimulator.

No the soil I mixed in with the natural soil had stimulator

Ahh, that makes sense now. I was going to say, I've never heard of them using root stim while still in the container. Kind of defeats the purpose.

More than what was in the tree/shrub soil I bought?

I don't think it's possible to overdo it with the root stim. However, I'd wait 2-3 weeks before adding more. When I planted my magnolia, and red bud, I hit it with root stim like once a month for the entire summer. The Magnolia is about 1" thick around, and 12-15' tall. So it's tall as shit, and thin. I don't even have stakes in anymore, and you know what the wind has been like lately. Tough ass tree, because it rooted well.
