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.
