should cause no problems to have your gun Redwood keep growing, I have two in my front yard which is maybe smaller than average and they are they magnificent presence in that location and have no problems with their roots or with their limbs. Because of the size of our yard we have pruned the Dawn redwoods Oh up from the bottom so they’re no limbs till you get to about15 feet or so. 15 feet or so it’s only downside is it size if you have a big small yard It’s Major downside is it’s very big for a small yard unless you prune it up. We have many plants growing below it with no problem. We give it extra water during the heat But I’m not sure that we absolutely need to do so. In China it does grow in river bottoms and it’s called the water fir. If we had to move and could take only one plant with us I’m sure my wife and I would agree that Dawnwood would be our unanimous choice. it is one magnificent, splendid plant with its birth millions of years ago, probably coexistent with dinosaurs. I’ve never heard of one having a disease or dying prematurely like many other trees much more recent origin. I would put this in the same category as the ginkgo tree also from China.
