The first image is of one of my box balls, the other, the second one, its twin- same stock; they stand either side of my front door, 1.2m apart.
Box 1, the ailing one, has appeared 'different' for about a year after 5-6 years growing identically. I swap their positions every 2nd year or so. The leaves are deeper green, shiny, more, maybe 'brittle-edged'- not perhaps 100% 'healthy' when compared to Number two, which is blooming (as it were). New growth is consistent vibrant lime-green.
This issue has appeared in the last 2 weeks.
Do I have box blight?
And yes, I know what to do with the plant and soil, but what shall I sluice the container with to free it of that fungi/virus so I can start again?
I've lost about 8 box bushes this season to caterpillars - they've destroyed them - do. you have any webby/thready type bits around them? Can you see any caterpillars? This season for us has been particularly bad - we've been told that the offending bushes need burning to get rid.....
