I found this at a nearby nursery yesterday. The pocketknife in the second picture is a hair over 4 inches long. I was pressed for time, so didn’t dig around the base to find how deep I need to go to find the roots. It’s the biggest dawn redwood I’ve found so far looking around the various nurseries, but that may have something to do with the season here. I may go back today to have another look, but thought I’d ask folks here what they think.
