Question
A few of my korean boxwoods have yellowing leaves.  I fertilized them with evergreen fertilizer.  I put my coffee grounds on my evergreens all winter.  Is that a good idea?

Answer
Hello Phoebe

This could be just a case of winter scorch from cold winds.  I suggest that you wait until the weather warms up to see if the plants continue to grow well.  If they don't, there could be a more serious problem, which will need to be addressed - let me know if this is the case.

Coffee grounds can be used as a very mild fertilizer, so it shouldn't have done the plants any harm.
