farm hunter; if you really want to keep the cost down, fill the 1-2 liter pop bottles (clear preferred) with planting soil. Plant the acorns/seeds in these and grow them through until the fall. They will then plant out with a good root ball and you can then use the pop bottle as a grow tube.

Timbercruiser is absolutely correct about final spacing. I just like to over plant to take care of the ones that die off, to let me select the best trees and to help kill off the grass by getting quicker shade.
