I’m installing a retaining wall for a concrete slab. This root runs through one corner of that wall. It’s about 1-1/2” diameter. This tree (Blue Spruce?) is probably 50 to 60ft tall.

I accidentally hit the root a few times with a shovel and opened a few large wounds. I’m not sure if that makes any difference.

It’s winter in Northern Colorado. This is the only root I’ll need to cut. I just want to make sure I don’t overly stress or kill this incredible tree.

Additionally, if it is ok to cut, is there anything I should do to help the tree heal and mitigate infection?

    Go for it. It’s clearly going to be in the way of what you are building. It’s relatively minor size

    No crushed gravel base? Personally that would be my solution. Bury the root in crush them before adding course of brick

    Also cinder block is no bueno for retaining walls, but I’m not really sure what you’ll be retaining with it

    This root is probably one of the smaller ones this tree has. I’m fairly certain tree can cope with its loss as long as you put lights on it. Because that is one Majestic Beauty!!

    Prune it with a nice clean cut! Dont bury it under your wall. The wall will get messed up from the root growing!

    It might be fine but given all the other construction activities there is probably root damage elsewhere and potentially soil compaction that will hurt it too. I would move over the slab if possible. Tree might be fine but it could also weaken it.

    If that’s the only root that is in danger of being cut, I can’t see it causing anything more than the most minor stress to the tree. If you do, just make sure it’s a clean cut.

    Yes, I cut many bigger on my silver maple and ypu basically cant kill the thing.
