Help with a new hedge

Berberis would be my choice as not too fast growing. I also like Pyracantha but they can get a bit tall in my view and not as easy to keep in check

We have a lot of different hedging. The easiest has been the hornbeam and also the beech (beech keeps it's nice autumn leaves, purple and green mixed is quite attractive and gives some privacy. The berried prickly hedges are a bit of pain, they look nice but spread by seedlings and are stiff to cut. We have a nice mixed hedge of hawthorn.  sloe. wayfarer, eglantine and hazel, the hazel is very upright and needs traditional layering. Our best new hedge is yew, strong and easy. Hmm lots of choice TDA, be careful with your choices! That said I much prefer hedges to fences. 

Edit   Photinia, Red Robin might be nice?

I have a Photinia rr, it’s a bit open, I’ve had to interplant to thicken it up. Beaut colours of the new leaves👍🏻

Pyracantha? Anti-social thing. Only fit for Indian Fakirs.

Great security though and only needs minimal  looking after,

Good point it really disrupts the thieves & burglars nefarious comings & goings😂😂

Yes, I can see that might be needed. Don't be tempted to buy the dwarf Red Robin either, our neighbours did this and now have a one foot hedge...

Thanks ET. My concern about Berberis is that it can be invasive, but how invasive I am not sure. Lovely colours though.

My daughter planted a Berberis hedge in her previous garfen, I pass it regularly Not been any problem at all over 20 years 

Beech would be lovely, especially if use green and copper. How fast does it grow though, as this will be newly planted, and we both have dogs. The Photinia RR is a lovely possible. 

We have just been chatting and hazel might bring us more problems, as we already have hazel trees, and the ruddy squirrels plant their nuts all over, we are forever tugging up seedlings. Would be a cheap option though, growing our own😂 but they do make a mess digging lawns up.
