That's a small pseudolarix to the left there

Cupressus bakeri came through no problem. Platycladus seedling to its left.

Plants don't "know" anything about windchill.

In and of itself, no, but wind can dry out conifers and make freeze damage potentially worse.

My C. obtusa 'Chirimen' sure didn't like -17f. Dead. :(

But those plants won't like each other before long . . . far too close together! That Pseudolarix won't do too well when the Sequoiadendron has a trunk a metre in diameter ;-)

I agree and also to close to the wall.

On the other hand, their proximity to the house may be their saving grace, due to its moderating effect on temp. and wind.

No advice was requested regarding the proximity of the plantings, but the thought is appreciated. The sequoiadendron is mainly an experiment, and should it survive a few more winters, the pseudolarix will be moved. Same regarding the Platycladus. Seeing as how the lot is small, I did not have the luxury to plant them far apart. Instead I must plant and see what does best and cull or move the rest. But really, thank you. The point of this post was mostly about seeing that these plants survived the recent cold spell. Heh heh...jeez.

Also, hairmetal, thank you for promptly handling the aforementioned idiotic question.

You are right shastensis. I have also a lot of windchill the whole winter and have lost in the first years a lot of plants p.e. ca 10 Sequoiadendron cultivars, Sequoia,Cupressus a.s.o.
So you must find a place with less windchill or stop planting.Try and error.
I do the same.

shastensis, I think Resin was "just trying to be helpful."
I do the same thing myself...put small plants near the house. Though in my case it's also because it's less of a hassle to water them than to try to drag a hose around 3 acres. But they have a way of getting away from you!
