The Eastern, or Canadian, Hemlock does quite well in good soils well endowed with organic matter with a soil pH in the 6.0 to 6.8 range while the Mountain Hemlock seems to do better in a sparser soil although the soil pH should also be in about that range.
Nutrients should be in balance.

Thanks for the reply Kimmsr. It's good to know Ph is okay, it is Can hemlock seed. As far as the calcium I will try gypsum.There is lots of OM in the area, I've mulched with leaves and pine needles in that area. I am going to be gone til Dec 1 so I won't be getting any more messages on here til then. So thanks for your help. Poaky1

Hemlocks do self seed. That is how they grow so many out in the forest.

I'm in Florida,using a friends computer, I didn't ask can hemlock seed the can hemlock stood for Canadian hemlock
