Greetings all
Going to try and respond to Calvin's questions here tonight. So, here goes:
Mark, this is an interesting topic for me, mostly along the lines of protection. So your tree was protected and yet it still suffered severe dieback. I need to ask some questions.
1. How old was the HC?
--- this was started early winter 2013, so it was not yet a year old and this past Arctic winter was its first
2. Was it completely hardened off before you protected it, or was there still green wood?
--- completely hardened off, had been in ground and growing, fertilizer stopped a long time before winter: actually covered it once all leaves had naturally fallen and before any arctic blasts hit the area
3. Because it's hard to tell sometimes in a picture, how thick was the layer of leaves from the core where the tree was to the outside of the wire cage?
--- I think this is the culprit that didnt help. I had some extra hardware cloth that I made a circle and staked it around the tree firmly. Problem is that the distance from center of tree to the enclosure was probably only about 6inches, so the total diameter was about 12 inches, max 14.
4. Were the leaves just loosely filled into the wire cage or were they packed a bit?
--- i used a mixture of mulched and just raked. Again, by the time I got to this one, i probably didnt have enough shredded leaves and used mostly just raked oak leaves.
5. The outer layer just being a trash bag I'm sure leaked moisture at least some, were the leaves moist/wet when you uncovered it this spring?
--- surprisingly, the leaves inside stayed quite dry and there really was no moisture inside.
I do think that my problem with this particular tree was that it was a lot more exposed than other trees i protected, and I didn't use a large enough container, and I should have used all shredded leaves, vice mostly unshredded.
Hope this helps!
If you look at pix in the initial posting in this thread, you can see my other winter enclosures were much larger, and they worked well.
