Never spaded Cedars. Different Oaks and Maples, yes, up to 6" DBH. Problem is watering them enough to get them to take. It takes a LOT of water and it's got to be done at least once a week, depending on the rainfall, soil and temp.

I get a lot of trees from the state. I can get 2 year and 3 year old trees for around $0.38 - $0.40 each in packages of 100.
