Question
Hello, I planted a few Canadian Hemlocks last summer, I have one tree that is turning brown on the bottom, My Question is how do I save this tree and can it be saved.

This may be evidence of transplant shock. This is that adjustment a tree goes through getting use to its new surroundings. Selecting a good site, proper planting techniques and a through watering at planting is helpful to minimize this stress. A through watering helps to ensure that the roots come in good contact with the surrounding soil.  Roots often stop growing when they encounter an air space created at planting.

I do not know how many trees you planted.  Is this the only one doing the browning? This may be a sign of stress and time will tell the story if it looks like it is getting some new growth or not.  If the browning continues to worsen, replacement may be your only option.  Ideally, at least in my part of the world, the best time to plant a tree is beginning in October and continuing until May. Always be sure the soil drains well in the location.  Soils that have a lot of clay can lead to root rot problems.
