Depending on the variety and cultivator, growth rate can be from a medium rate to slow rate.

Can I plant (3) 8 ft Hemlocks in Northern NJ now? I have purchased the Hemlocks and must pick them up by Dec 20. What is the risk of planting them now? Any suggestions to reduce the risk? How do I test for soil acidity? How do I add-subtract acidity? Thanks, Kelly
Early Fall is the best planting time for your growing zone. You are now in early winter and this is very late to attempt to plant the trees.
They will have very little time or any time to become established in the ground. The roots could freeze quite easily and you will have dead trees come spring.
If the garden center you are purchasing from will guarantee the trees and replace if they die, then you have nothing to lose except time and effort.
A soil test can be done easily. Contact your local County Extension office and they will be able to help you.

I ordered a 120 Canadian hemlock trees they came in bags bair root we planted them the same day they arrived on a drip line around the 1st of May it still cool and rainy in Colorado but the next day after planting they started losing needles and now they have none all of them . They are still pliable will they come back around ? And I can't figure what I did wrong? They were about 6" trees any thoughts or advice would be appreciated.
Planting stress may have caused initial needle drop.
Watering is key; daily for the first 2 weeks.
Continue watering and they likely will green up next spring.

Canadian hemlock needles turning yellow color what can I do thank you in advance
Yellowing can be a sign that the plants' roots are not in well drained soil. Can also be a sign of higher than normal ph levels (conifers are acid-loving plants - low ph).
Canadian Hemlock are also very sensitive to drought, so if you have had dry weather you will need to water your tree.
They are also susceptible to the Wooly Adelgid pest.

what would cause a hemlock small tree to drop all its needles in a few days
A diagnosis such as this requires a fair amount of investigation. Were the needles discolored before they dropped? How old is the tree? Was anything sprayed near the tree? Here is an article that will help you get started with a diagnosis: https://www.gardeningknowhow.com/ornamental/trees/tgen/why-conifers-drop-needles.htm
Hi - I am looking to purchase a weeping hemlock tree for a garden in the Catskills and am having a tough time finding any for sale. Would you be able to direct me to any reputable sources where I could buy one? Thanks.
Do a Goggle search for Weeping Hemlock, you should be able to locate a grower that can ship to you.
We do not promote any specific sellers.
How far can I cut a branch from its tip towards the trunk of the tree?? If I cut a branch past its needles into the wood, will that hurt the branch? Will it still grow? I was told that you can cut a branch back one third of its length and it will still grow. is that true?
Don't remove more than 25% of the branch, or of the entire foliage in a one year period, is the rule of thumb for best management practices in pruning.
Be conservative and don't remove all the foliage on a branch, leaving a bare stub. It's ugly and on a conifer it may not re-foliate.
