I have this small shrub which was so healthy in the spring as well as all the years I have had it. Then all of a sudden about a month ago we found the leaves turned brown as though it died, It happened quite rapidly. But there are still some leaves poking through that seem unaffected. It looks really weird like the leaves have been eaten from the inside, and whoever did it left all the edges of the leaves intact. Almost like eating the inside of a slice of bread and leaving behind the crust. :) Does anyone have any idea what may have caused this? Could it be an insect or maybe a disease?
I found out what this was. This is a Boxwood and it has been eaten by the Boxwood tree moth larvae (Cydalima perspectalis). I think it's too far gone and I have to remove it. Cydalima perspectalis (Walker) – (Box tree moth) – Fact sheet - Canadian Food Inspection Agency (canada.ca)
Thanks for reporting back on this. You'd think it wouldn't have been in their interest to do in the whole plant.
I have three boxwood , each in a large container - purchased at same time approx 10 yr ago. I have the name tag but it is not near me at this time - it’s a good round small size boxwood 2 are nice vibrant green - happy and healthy even with heat, smoke, minimal water this past summer 2021 1 is dry fading green The one fading away had a white powder on it sometime last year (it’s all a blur :) It was like a dusting of very dry snow which you’d know if you live in a really low humid winter climate In any event - I suspect my dying plant is a similar situation to OP boxwood EDIT - the 3 I have each in large container are Green Velvet buxus Boxwoods Make Gardens Better
