Q.Why is this evergreen dying?
I bought and planted this in April. It was doing fine until suddenly last month the limbs started turning brown. The 3 brown ones turned quickly, the fourth higher one has only recently started to turn. Does anyone have any idea why it’s dying? I don’t see any bugs on it and it’s been watered regularly.

Unfortunately, it may have been watered a little too regularly. Overwatering is the most common cause for needles or scales turning brown. Cold is another cause, but this will, clearly, not be the case here.
It is best to only water once the soil is dry down to about 4 inches or so. These trees are quite drought tolerant, and will not need extra water unless there is drought. Even then, it is best to allow the soil to dry out down to that depth before watering again.
From here, you will want to cut off the browning portions, as they will not return to normal. Treat with a fungicide as well. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
I would also treat with about 1/2 cup of DOLOMITIC LIME and a tablespoon of WETTABLE SULFUR. This can help to remedy the situation and bring the soil back to a more suitable condition.
