The Q&A Archives: Yellow Leaves on my Shrubs

Question: What should I do when the leaves on my Boxwood shrubs start turning yellowish brown?

Answer: Boxwoods tend to drop their oldest leaves (toward the inner part of the shrub). As long as new growth is a healthy green, the yellowing and dropping leaves should not cause concern. They will be replaced with healthy new leaves later in the season. If the newest foliage is turning brown, water stress or a need for fertilizer are the usual causes. Hope yours is just naturally dropping the older leaves.
