Instant hedging

[Karcheer]

We currently have a scrappy looking hedge between ourselves and a neighbour, which is going to look more gappy in the next week or so as our neighbour is removing her bushes to replace with a wrought iron fence.
I’d like to replant the gaps with mixed native hedgerow. I’ve been looking at instant hedging.
Can anyone recommend a company for this? And advise if this is a good idea?
Thanks... I’m rubbish at gardening!

When we moved to our current property the hedges were a right mess. filled with ivy and so much dead hedge under they were collapsing in places.
I spent ages ripping all the ivy out and replaced with bare roots in the gaps, the roots from the existing hedges were huge and there's no way I'd have been able to dig enough to get an established hedge plant in there, except where there was a good 2 foot gap through dead hedge, this was probably only in 3/4 places along a 40ft hedge - it's already looking a million times better 1 year on.

I have now started on the back hedge which currently looks butchered as it was so wide we've had it cut in half width wise, again the neighbouring field is full of bramble, ivy and stinging nettles in the summer so I am spending ages weeding ahead of us replacing the chain-link fence, any gaps will be replaced - ideally next weekend before its too late with bare root plants and I know come next year it'll look a million dollars.
Just look at how harsh farmers cut their hedges and how quickly they ping back.
I used hedges direct for the bare root plants and they do packs of mixed native hedgerow. I'd seriously consider saving many pennies by doing it this way as I believe they'll fit into your current hedge far better.
For the back to try and hide the swamp...I mean field behind us I plan on using beach so the leaves stay in place over winter and provide some screening, may be worth a thought if you don't like the wrought iron?

oh I love beech hedging !
