With these it is kinda up to you. I left the lower branches on this one and got a neat lower trunk at the exchange of having to get the trimmer out a dozen or so times a year.

Yours looks great!

Here’s another pic.

its your tree.. and your saw.. and your whim ... all my trees were pruned up high enough.. that i could mow on the garden tractor at speed ...

when you have a goal.. YOUR goal.. its not hard to accomplish such with a goal ...

there is no tree bible that states some certain height is proper or perfect ..

ken

There are four other residental metasequoias I drive by locally and a slew of taxodium.

They are pruned up what, waist to torso high?

I leave the lower branches on my other trees I prune up, but more slowly than most. They seem to deter deer slightly.

I agree with ken . Unless you like trim mowing either with a push mower or weed eater, ALL trees and bushes should be trimmed so that you can EASILY mow under and around them. Unless you have a 200 year old oak with a branch that droops to the ground

To me spruces look much better with branches all the way to the ground. I know nothing about dawn redwoods though.

I had to limb mine up more after this pic to keep open access to the spring house. Even limbed up a bit, the lowest branch away from the building is low enough that you can touch the foliage if you reach up.

imo... the only reason to keep tree low .. is to hide that buttwipe neighbor you dont want to see for the rest of your life.. lol ..

that said.. i dont prune up conifers.. that self mulch and kill all that tries to grow under them... like water hog pines that suck up all the water under them.. when they are 20 or 30 feet tall ... same with spruce.. etc ..

in teh pic above.. its a shame bengs tree is 20 feet to close to the structure .... and 20 feet too close to the utility lines.. who placed that tree .???

another reason to prune up.. is to see the garden or plants behind.. that you want to also see from the beer drinking throne on the patio ... or deck
