When to trim 5 foot tall boxwoods?

Question

We have 4 large leggy boxwoods that have been ignored for the last 3 years. They may have some blight, or simply be under fertilized.

Answer 1

You can trim at any time unless it is late Autumn. It will be too cold to recover.

You will also want to correct the issue before pruning. Doing a heavy prune on top of an issue will almost be guaranteed to cause its death.

If you can include photos, this will help me to see what is going on so that I can recommend the best solution.
