There is no regular fertilizer guideline for Boxwood.
The most reliable guide is a soil test to determine if there is a Nitrogen deficiency.
The first signs of a deficiency is yellowing leaves, generally will start on the bottom branches and work it's way up.
If you determine that your plants need a fertilizer, use a granular urea 10-6-4 or something similar.
Scatter around the drip line as this is where the most active roots are.
Do not over fertilize, as this can lead to root burn.
