Thank You Michael. I’ll hop right on it with the Cooper and see if I can track down ZeroTol. Again, Thanks!

Indeed, these houses were made with all views of the interior walls of the garden…nature and man together. I think a much better appreciation can be seen from the intent of the architects and designers, given religious and cultural facts…and the key idea was not the “garden”, but, “contemplation” I think. Perhaps there are a few other ways to force man to think about his place in the natural world, but….

Michael, It still happens. I ran across this article and saved a copy. You might enjoy it.

Many fungicides may be used as a drench, regardless of soil moisture. I would try a spray regardless. As for how often consult which product you’re using. The ZeroTol I use as a preventative spray several times in the dormant season.

Michael, I read this when you posted it and never heard of it. But 3-4 wks ago, one of my JM’s had this exact thing on it. (An air layer from last yr). The tree is inside my overwinter hoop house. I cut off the infected part, but can’t treat it as the soil is damp. What would you do here in Jan? Should I treat my other JMs too? I can always spray, but not the drench.

Thanks for bringing this up! I’m new to JM’s and never heard of it before.
Chris

Comment on Winter Cold And Tree Roots by Graham

Hi Michael, again an interesting topic of discussion.

A timely one too, as Anton and I were reviewing this very subject recently.
From my side of the fence (work wise – forest management) we are very aware of dormancy (is broken into quiescence and rest dormancy).
Quiescent (earlier stages of dormancy) is a stage where conifers if well irrigated or moved to a greenhouse where a favorable growth regime is maintained (or for us if we have unseasonably dry/hot weather periods in late summer) it will become active again and break its bud and resume active shoot elongation (we get this in many of our conifer plantations, during some warm late summers = Lammas growth). In contrast, a conifer in the “rest” dormancy stage will not grow regardless of how favorable the environment is.
Sounds like your climate only provide the quiescent dormancy whereas up here we get the full rest dormancy .

That’s a good point. The trunk is riddled with what looks like carpenter ant galleries, and looks truly antique, and yet the trailing branch and pointy top of the past design both indicated youth.

Sorry for your loss… that is a sad story. I had a yew once when I lived in upstate NY—still have it, actually—and a light snow covered everything that was green except for the bonsai benches where the snow blew off. Revealing my yew. Which was then restyled as a semi-cascade by a hungry deer. Improved it greatly.

That is a good idea. However I find that in pots unseasonably cold storms in otherwise mild times of the year or climates can still damage plants. Potted plants are really sitting ducks regarding cold—when it’s not cold, their roots will grow. And then it can get very cold. All we need is a 40 year storm to kill a tree we’ve worked on for 20.

It is an interesting problem. I think we simply need to be very cautious of trees that have not had frequent light frosts and lower light before exposing to deeper cold. Dave is a great resource. Our climates are very similar, he lives and works near Tacoma and the conditions are similar here in Portland. What I’ve seen is that partial dormancy occurs with changes in daylight and lowering temps, but full dormancy does not happen here. The roots remain active most winters. Sounds like you’re in a much colder area, and you won’t have as much worry in the deep of winter. The scary things are the storms that come out of nowhere and are very unseasonable in severity, in the spring and fall.
