I have noticed most Metasequoia Glyptostroboides – Dawn Redwood Bonsai trees are designed like a typical conifer tree would be with the branches styled in a downward motion. Dawn Redwoods growing in the wild do not grow with there branches pointing down towards the soil, they grow up and they stay that way. They never arch over and I think Dawn Redwood Bonsai should be designed the way grow in the wild. I have created a Dawn Redwood page under Redwoods, Conifers and Bonsai Tree Information.
Please spend some time studying the trees in the gallery. I think you will be surprised on how they actually grow.
