Weed/Grass/Plant barrier under fence

[ThyJones]

Hi, I'm not far from putting up a new fence (individual slats) and this will be very close or on the existing grass.

I will be putting wooden (gravel) board and the fence on top. The problem I think I may have is grass/weeds/plants growing underneath or behind the fence. Is there anything I can put behind as a sure way to barrier against this? I've used normal fabric barrier stuff before but never particularly impressed, and I'm worried plastic membrane may cause water build up.

Any suggestions for anyone who may have done this please?

See my rubbish image, the black bit is where i think I may need to place barrier?

Thanks

A bit of grass won't hurt the fence, and if it needs tidied up just run a strimmer along it once or twice a month

I know it won't hurt it but it looks rubbish if weeds/plants etc come through the boards, I want to reduce it happening. I've got about 60 fence panels to do so ideally want it as fool proof as possible so I don't have to spend hours tidying it up as much.

Concrete gravel boards......

That would work fine except we only want wooden posts and wooden boards and to do away with / hide any concrete attributes

Leave the boards 3" from the ground to provide access for hedgehogs plus they won't go rotten at the bottom.
