Too late for this Hemlock?
This Tsuga canadensis has been in the ground for almost 3 years and was doing fine, until now. I noticed it turning brown over the past week, and it is progressing quickly. I've inspected it for wooly algecid & other pests, and see nothing. It is on a fairly steep slope, and I have tried to keep it well watered and mulched. It is in a partly shaded woodland area, good soil, no drying winds. The only thing I can come up with is shortage of water last summer and it is only now showing signs of stress. Any thoughts on what, if anything, we can do to save this tree? Thanks for any suggestions. I love hemlock, but have not had good luck with them.
