Is my boxwood sick?

[mrfish33]

This boxwood (maybe Goldilocks) has been really healthy until a month ago. It suddenly got yellower. I up potted last year with mostly new soil. Watered daily when hot, twice a week when cooler and more humid. Fertilized start of summer. Any thoughts?

First you should add your location to your profile so I wouldn’t have to ask if it has been cold where you live? My boxwood changes color when it gets cold, but yours looks more yellow so it may be something serious.

Seattle area, so lowest temps so far are upper 40s. This thing lives outside all year even in worst weather.

Damn. Maybe it’s boxwood blight? Hopefully not.

Can you send close up of leaves and branches?

What soil is it planted in.

Soil is a mix of akadama and potting soil which it went into 1+ years ago after just being in nursery soil. I feel an up-potting might be in order.
