Blue Atlas Cedar dying
I planted three Blue Atlas Cedar back in the late Spring. They are planted along a North/South wall on the West side of my home. They get part sun.
After planting and through the summer, they seemed to do REALLY well. All three had new growth and produced cones. Over the last month, they've begun to drop their needles. The Southern most plant has dropped about 25% of it's needles, the middle plant about 50% and the Northern most plant, about 90%.
They are planted in a somewhat raised bed so I don't think drainage is an issue but maybe. I'm wondering thought if they aren't getting enough sun. With the shorter days, would that be what might be killing them?
Should I move the worst to an area with full morning sun to see if it will come back or would that be too much of a shock?
Please help. I want to save these guys but my brown thumb seems to always kick in.
