Tsuga canadensis is one of my favorite species of conifer. For my yard they were perfect and one of the few conifers that thrives in shade. I think this infestation has spread too far to be controlled with predators of the adelged's at this point. For the past 10+ years the Arnold Arboretum has been researching alternative Asian hemlocks to replace the Eastern Hemlock. I think you would be better of getting Tsuga diversifolia or Tsuga chinensis. They don't look quite as nice as the Eastern hemlock in my opinion, but do share the ability to thrive in shade and most important...have shown very strong immunity to HWA, especially chinensis Here is a link that might be useful: Arnold Arboretum article

well, 'inferior to' leaves a pretty wide berth for the imagination but a google search brings up many links to HWA resistance of T. sieboldii and many of then say that while T. diversifolia and T. chinensis have excellent resistance, T. sieboldii show little damage even though some HWA may reside on the tree itself. To me that would be good enough to try one. :) https://www.nrs.fs.fed.us/disturbance/invasive_species/hwa/control_management/hybrid_hemlocks/

Just might do that! lol I may later on do more in the way of 'islands' around some of the trees and add something or other under them. Something to think about next winter. I'm leaving the center of the yard open, so when the grand kids come we can throw foot ball etc. As viewed from the deck almost directly SSE. The wife decided we should leave things so we can 'drive through' past the house in to the front yard for furniture/appliance moving etc. Front yard not so big but I had to move the lily station because after we added the bb hoop, we couldn't drive around that side of the house without running them over. You can see in the grass where it used to be. It was so root bound it hardly bloomed anyways. I'm standing in the neighbors driveway to take this pic. My yard ends several feet this side of the green ash in front of me. All this and my deer farming in the countryhas been quite enough for this year. I just finished my third week of full retirement. Well at least I got everything I wanted done for this year. Sometimes our Autumns can be quite wet so not much gets done.

Very sad to see the demise of such large forest trees. Is there any headway being made with the predator beetles that were released a while back? The one in Brainerd might have been much taller with less taper, if it was in a setting with competing trees. The branches go all the way to the ground and some are at least half as long as the tree is tall. If more of that growth had been further up the crown.... From the looks of it, there hasn't been any pruning done to the tree. The branches overhang the garage and lower entry of the house. The owner said he had to put hoods on his rain gutters because they would fill will needles and other trash but he's happy with the results. I forgot to ask if he ever found any seedlings around the property. And I should've asked what type of soil is there. The banks of the river are quite steep and at least 100 ft. below street level. It may be a different type of soil along there and may even be underground springs that helped cause this anomaly. Oh well, more to ask about next time. :-)
