Answer: Staking is not necessary unless the trees are planted in a windy area. Sometimes stakes are placed around a tree the first year to keep it upright while the roots become established, but unless you see your newly planted trees listing to one side, staking isn't necessary.
If you do decide to stake your trees, use 3 sturdy stakes placed an equal distance from one another and the tree, then tie the tree trunk with 3 individual lengths of soft material (old pantyhose, strips of old sheet, etc.), connecting each to a stake. This will help avoid damaging the bark. Be sure to remove the ties and the stakes the following year.
Best wishes with your new trees!
