Re-Locating A Dawn Redwood Grouping

I am new to the bonsai world and last year (September) ordered a Dawn Redwood (5 tree grouping) to get my feet wet. When ordered I lived in San Diego, and although it took until January for the leaves to fall, the trees seemed to do very well. I did my first pruning in February (once I saw the buds starting to break open) and the growth took off.

Last week I moved to Hailey Idaho and I have some concerns I am hoping someone can help with! The temperature here is just now starting to be above freezing at night (between 0-3 Celsius / 32 -38 Fahrenheit). The days have been warm at (13-19 Celsius / 55-65 Fahrenheit))Because of this, I left the bonsai in my garage for the first 3 days to help it acclimate to the new temperature while making sure it (and the new green shoots) were not exposed to sub-freezing temps. I moved it outside last week once the lows were above 3 Celsisu/38 Fahrenheit) and it seemed to be handling it pretty well. It has been getting ample water and southern exposure (roughly 8 hours of sun from 8:00am-4pm). Although the temperature is lower in Idaho than San Diego, the bonsai is probably getting double the amount of sun it was getting while in San Diego. It has been outside in Idaho now for 6 days/nights.

In the last 2 days, the leaves on the outside of the trees have begun to brown slightly. The browning is also occurring on the moss in the pot. Since there are so many new variables, I am not sure what is causing the effect and what steps I should take to make sure the grouping survives the move. Any suggestions?

Probably your new location is at some elevation? Less dense atmosphere means more intense sunlight. But your trees need to adapt, I would just leave them where you have them, you might loose some leaves, but the new leaves will quickly replace the ones you loose.

Should do fine. Make sure it isn't left out in the frost/freezing weather. Its in leaf, which means it has exited winter dormancy and isn't freeze tolerant at its roots anymore.

Dawn redwood is pretty cold hardy, down to USDA zone 4 in the landscape (which means around Zone 5 in a pot). It will need some winter protection in your winter.
