Hi I have a question regarding boxwoods. I have a row of them in my pathway shaped in round circles however I would like them shaped smaller but they aren't green enough or filled all the way. I'm assuming they are lacking something such as fertilizer or plant food. However, I have no idea how to treat them. Any suggestions

You can make them smaller but, as you pointed out, there are no leaves in the middle of the plant. You will have bare branches for a season before leaves grow. I have cut them to the ground and they grow back.

I can't tell from your photos if the boxwoods have another problems. Maybe some closer photos will help. How often do they get watered? How long since they have been sheared? Are you looking at the brown edges of leaves that have been cut in half?

Looks like they have recently been trimmed, and need some time to green up.
I think ! they may need more water.
A lite app of fertilizer, be ok, if there not stressed.
If any dead spots. A trick i do. Is cut dead stuff out. Then take a few green branches and pull and tie them together in bare area.
If your going to reduce there size. You need to wait untill early winter when you have cool weather, or they will burn up.
