    We are currently pruning spruce at 10-25 degrees F. Does anyone have information on appropriate temperature ranges for pruning? The best I find is to avoid predicted sub-zero temperatures. Thanks for any comments!

    No idea what "10-25 degrees F" means. But it doesn't matter what the temperature is, as long as it is comfortable to work in. Above 20°C, it's too hot and sweaty work to be enjoyable.

    Below about 5°C, you need gloves, which may hamper pruning efficiency. But beyond that restriction, sub-zero temperatures down to about -10°C aren't too bad to work in as the physical activity keeps you reasonably warm (if it isn't too windy). Colder than that, stay inside in the warm!!

    Thanks. Thinking in Fahrenheit here! Research in Oregon says not to prune when subzero (Fahrenheit) temperatures will occur after pruning. Apparently pruning has a temporary effect on hardiness...
