Growing Wholesale Tree Growth Rate from Seedlings

[arminius]

Located in MN, and I'm starting Tree Farm, and going with 15# grow bags (18" x 14.5") and each of the following I'd be starting with 1-2 year old seedlings, abut 10"-12" high each. If I water well, fertilize, and keep weeds down, can these trees make it to 6' tall in about 3-4 years?

- White Spruce
- Autumn Blaze Maple
- Thuja Green Giant
- Flowering White Dogwood

Yes easy just keep them from drying out in Summer.
