My boxwood hedges down the front path are showing yellowing/orange leaves which fall off. The bushes are about 45 years old. They are in full sun but did have a little shade from a pine tree which has been gone for a year or so. I have always taken care of them and I do not want to lose them. I fertilized them with an evergreen fertilizer in a granular form a couple of months ago, and they responded very well to that with lots of new growth. Yesterday I laid down an inch of fine shredded bark mulch. When the pine tree was near I used the fallen needles as mulch.
The foliage in your photo shows winter damage. We do not see any evidence of disease. Many broadleaf evergreens have been affected by our cold winter. The leaves will eventually fall off. Simply rake up.
