Weeping norway spruce struggling
I bought and planted a weeping norway spruce into a flower bed a couple of years ago. I love this tree! It has done fantastic for the last couple of years but a couple of weeks ago I noticed it started browning and dropping needles. It had a lot of new beautiful buds this spring and has taken a turn for the worse. I dug around the root ball to check the moisture level and it seems to be ok. I manually water this flower bed and it occasionally catches overspray from the sprinkler. I noticed that there are a lot of shallow roots spreading through the top couple inches of soil. My neighbors weeping nors don't have the shallow roots like mine. I'm not an experienced gardener and need help to save this tree. There are boxwoods, hostas, a false cypress and a host of other small plants in this bed that are doing fantastic. I'm just not sure if it's a watering issue or some type of disease. Please help me save this wonderful tree.
