The drive is to be resurfaced but before I have it done I want to get rid
of Moss etc.

Thoughts are to give a double treatment a couple of weeks apart before
machine brushing (Bobcat mounted brush) to remove the dead moss and loose
surface dressing.

Glyphosate will be used also as a systemic weedkiller.

Any recommendations on the best *moss etc* killer applicable during Feb/
March months - staining will not be a problem due to the resurfacing.

Iron Sulphate as a moss killer. Can't remember if it is ferric or ferrous.

Glyphosate will only work on growing plants to conduct it to the roots.
It is NOT more effective to use a stronger mix. That just kills the
greenery and does not allow it

Ammonium sulphamate (NOT Sulphate) will help kill roots. Technically
cant be sold as a weed killer but perfectly legal as a composting
accelerator. Thanks to EU nonsense rule interpretation in uk

A mix of the last two is fairly effective on Ivy esp with a little
washing up liquid to make it wet the surface of ivy leaves.
