Seedling
Hey all, I have a ~8 - 10 year old thuja occidentalis (eastern white cedar) and recognize it’s quite hardy. This is my first cold season with this tree (I’m in southern Maine, zone 5) and I’ve been watering as needed when the soils drys. My concern is that the cambium is quite dull and it’s not nearly as vivid as my other conifers in the cold frame. I’m not sure what it’s lacking / how I can improve the health of this tree, photos attached of its setup in the cold frame.
