Topiary Box Buxux Sempervirens

Hi
I have a Topiary Box Buxux Sempervirens purchased last November
All over winter the foliage has been a healthy green colour
Over last 3-4 weeks the leaves have started turning brown like attached pics
I dont know if the plant has got frost damaged or is dying or if this is expected behavior for the plant at this time of year

If it is expected behaviour for the plant at this time of year, when will it started to green up again
Thanks

 

Sorry, but that looks dead i'm afraid.

 

looks dead , strangely it died just now, they are really frost hardy (-20) and with all the rain we had it look strange that dry out .....where did you keep it?

 

Thanks All for the replies
I had it outdoors
Thought maybe the recent frosty nights might have damaged it
It wasnt getting watered as i thought with all the rain it wouldnt dry out
Ah well - its a pity that it dead but not to worry
Thanks for the replies and help

 

Don't give up completely just yet. Have a close look at the stem, particularly around the bottom, and see if there is any sign of life. If there is, you'll have to chop off all the dead brown stuff, give it a feed and keep it lightly watered.

It'll be a long haul, but if, like me, you enjoy resurrecting hopeless cases, it will be worth a go. However, if it really is dead, it's time to get another.
