Q: We are thinking of transplanting 2, 6 ft. Alberta spruce
trees that are 20 yrs. old, maybe a little more, to a house that we have
just built.
Would it be practical for us to move 2 of these that are
this old?
6' dwarf Alberta spruces are hard to come by, and when you
do, they aren't inexpensive.
Be sure to get a good, firm, properly-sized root ball. The root ball should
be 10-12" in diameter for every inch in diameter the trunk is (measured at
6" above ground level), i.e., a 4" diameter trunk requires a 40-48" root
ball.
They can either be hand-dug or moved with a tree-spade. Either way, I think
it would be worth the effort and cost, especially if they have a sentimental
value to you.
