Dilute it as per instructions.

I used a small bottle to measure about 50ml to a 10l watering can. The
instructions I was left with was 'about 2" in the bottom of the
watering can' so what would be the consequences of adding it in such a
concentration do you think?

The label says 45ml in 9 litres for mature plants and growing on, so
you're right on the nail. 2" in the bottom of a watering can sounds
much too strong. It could damage the roots. Always better too weak
than too strong.

Thanks and understood.

There are a few 'holes' in the foliage on some of the plants and they
look like this: (full size pic).

There's obviously been some dieback in places. It happens with all
sorts of shrubs from time to time. It might be just one of those
things, or it might be box blight. Either way there's not much you can
do about it.

Ok, thanks Chris. So there isn't any pruning or anything you can do to
stimulate any further growth in that area?

If they were mine, I'd cut out the dead twigs as far back as the
deadness extends, just to allow light to get in and new growth to fill
the gap, and to improve their appearance. But as they're not yours,
and IIRC your mate said it's been happening for a while, I'd not touch
them.

Indeed. I was just wondering if there was anything 'obvious
commonplace' that one does.

Anyway, if it's box blight, I don't think just cutting out the
brown bits is going to stop it.

Ok.
