These special “seed orchards” produce seeds that the propagators expect will grow into high-quality trees resembling their parents. Much work goes into identifying and nurturing seed trees until they are mature enough to produce seed, and then into collecting the seed and growing seedlings. Unless you have the time and expertise to take on these propagation tasks, it is better simply to buy planting stock from a reputable nursery. Nurseries now offer seedlings of these improved strains, and most Christmas tree growers are planting them instead of pulling small trees from the woods or planting seed from random native species, as was once done.
The additional year or two of growing time and extra room to grow in the transplant bed allow them to develop a much larger root system, which better equips them to survive field planting and get off to a fast start. There can be too much of a good thing, though. You may be tempted to buy the largest planting stock available, in order to shorten the time required to produce a salable Christmas tree. Especially large transplants, however, or those older than 3-2 (3 years of growth in a seed bed, 2 years as a transplant), do present some challenges.
A spade or auger will easily work through smaller roots, but larger ones might require extra work to remove. Planting a foot or two away from stumps can help to minimize this problem.
