Eastern hemlock is found in many different settings, largely due to the fact that it is shade tolerant. In its natural range, temperature averages vary from 10 degrees F in winter to 60 degrees F in warm months. Annual precipitation levels range from 29 inches to 50 inches. Physiologically, it can take 20 to 40 years before seed production takes place and upwards of 250 years to reach maturity. Eastern hemlocks can live for more than 800 years!

Even so, seedling germination rates are often under 25%, so the task is not exactly easy. The process begins with the collection of cones in the fall before any seeds have been shed. Allow the cones to dry and shed their seeds into a container. Place the seeds with a moist material (sand or vermiculite for example) in an airtight container in the refrigerator (40 degrees F) for approximately 10 to 15 weeks in order to overcome natural physiological dormancy. This is known as stratification and it is accomplished in nature as conditions in the forest floor are often cold and moist during the winter.

The Hemlock that I dug this week are from 36″ to 48″ tall but as I was digging them I was thinking how easy it would be to sell them right in the ground if only I had grown them on to a size of about 7′. It’s really hard for landscapers and re-wholesalers to find big evergreens because most growers dig and sell them at smaller sizes. So the larger trees really bring a premium price. And since they are so scarce you can often find a buyer that is not only willing to buy them, but they are also willing to send a crew to your nursery to dig them.
How do you make a root ball?
On a seedling a root ball is created by root pruning, or transplanting your seedlings.
