box trees

I read somewhere recently that this was a sign that they needed to be watered! Give that a try.

Someone else may have more ideas about the problem.

Hi Darren. Sometimes the leaves go a bronzy brown but are still alive, this is protection against drying out or cold and they recover again in the spring. If they are crinkly, thin and obviously dead. Thie trace down the stem to where you can see green under the bark and prune back to there. Spritzhenry is quite right about watering they ofcten go dry because the foliage is so dense. Make sure the water gets to the roots.

I would google this problem there is a disease that causes box to die back , you need to make sure the plant is not suffering from this.

If it is the disease that Box gets you can try pruning back to good wood. Be careful to burn or bin the cuttings as you don't want to spread it around. I don't think there are any sprays that work well. However, potted Box can get a bit stressed and the leaves turn an orangey colour, not brown or dead. Feed the plant well in spring as this will help it in either case.
