Talk:Tsuga canadensis

Comment
At 10:32, June 28, 2005 167.206.176.233 asked, "Is this poisonous like the plant that Socrates ate? My collegue from work just ate some at his desk.  Pray tell." In case the poster really wants to know (it looks more live valdalism), the answer is no, this is not poison hemlock. That would be Poison Hemlock. Henryhartley June 28, 2005 16:25 (UTC)

No the tree eastern hemlock Pinacae Tsuga cannedensis is a source of vitiman C and can be boied into a tea. Poison hemlock common name watercress is a herbasious plant is thought to have killed Socrates. In no way, other than both being plants, are these two individual plants related.

While many beleive that the Eastern Hemlock is delicios I fail to see how any body could sink their teeth into this ThingI mean really. Just the thought makes me sick to more then my stomach. I really don't know how any person, nay, anything could eat this. Even in tea. Gross, man. Really gross.

Drawbacks
The following line appears to contain an incorrect or out-of-date reference:

"It has several drawbacks, such as a fairly low tolerance of urban stress, intolerance for very wet or very dry soils, and it is susceptible to attack by the hemlock woolly adelgid, though this is treatable.[11]"

The referenced webpage currently contains no information about treatability/treatment of the hemlock wooly adelgid. Suggest adding a reference to webpage documenting wooley adelgid control e.g. http://www.saveourhemlocks.org/index.shtml

misleading or outright wrong unsourced comments
This article is full of a lot of unsourced assertions, and at least one of them I spotted that is outright wrong: "The tree is equally tolerant of full shade and full sun" Here is a source from the Ohio Department of Natural Resources:  that reads:


 * "Eastern Hemlock achieves its best growth in evenly moist, acidic, organic, rich, well-drained soils in partial shade to partial sun. It can tolerate less favorable conditions (such as full sun in average soils of alkaline pH) if sufficient supplemental water is given during the dry periods of summer, as long as the soil is well-drained. Eastern Hemlock does not tolerate wet soils, nor prolonged drought. Strongly windswept areas and air polluted sites should be avoided. It generally performs best in partial sun to partial shade, and is found in zones 3 to 7."

This fits with my own personal experience too--we had a hemlock exposed to full sun get hit by the Hemlock woolly adelgid. Actually, as I am typing I can look out my window right now and see a row of terribly unhealthy eastern hemlocks, planted in an exposed area and exposed to nearly full sun. Full exposure seems to stress the trees. Cazort (talk) 16:46, 25 June 2009 (UTC)

Extreme Concerns
Almost everything under the Hemlock Woolly Adelgid portion of this article is incorrect. Also, the distribution of these trees is now false thanks to the HWA. The last remaining hemlocks in the U.S. are mostly in Georgia, because the threat began in Virginia and made its way south, killing off almost every hemlock from Virginia to Georgia. If you want more accurate information please look at this site or find more up to date scientific articles. I know this article on wikipedia has a lot of false information because I am currently working at a lab to help save the last remaining trees.

 * I had to delete my initial response because it was rude, but there are still PLENTY of hemlocks in the Appalachians from Georgia to Maine. Famartin (talk) 01:41, 28 April 2014 (UTC)


 * Thank you for your work to help save hemlocks! The spread of HWA is definitely tragic, but I don't think I would go so far as to say eastern hemlock has been completely extirpated from its original range where HWA has spread. Also, there are still large areas of eastern hemlock free of HWA in the north and west. Tdslk (talk) 02:42, 28 April 2014 (UTC)

Porcupines
Not sure if anyone has a source for this but it could be added to the page. New world Porcupines seem to love these trees (Living in and eating them). I have many eastern Hemlocks on my land and the porcupines are decimating them more than any other tree on my land. They nibble on the maples a bit, but they are decimating the hemlocks. One porcupine can defoliate an entire large hemlock in a week. They get everything except the needles at the far ends of the branches, which are too thin to hold their weight. Maybe someone is aware of some study or something about porcupines preference for hemlock and can add the into to the article? I couldn't find anything, just my personal observations.
