Coppicing

I suppose much depends upon how “tidy” you want it to look. Thinning and grubbing is probably the simplest answer.



This is a stand alone hawthorn that used to be a hedge plant. It just needed space. It doesn’t seed regen because I occasionally mow my side of the fence and my neighbour’s stock graze the other.

If I had space I would love a thorn thicket; so much goes on inside them.

Off topic but if anyone wants to grow up a hedge plant - make sure that your chosen leader starts below any stem that has been laid in the past to get a secure stable trunk.



pee ess,
My ancestors would warn you to be very careful before doing anything with blackthorn.

Haha, yes, I have felt the wrath of those thorny curses

Hawthorn and blackthorn are traditionally hedge plants because they like to grow in a cris cross way.
Giving them space will help but, as Pattree says, it depends on your definition of 'tidy'.
It's unlikely to be a 'tidy' hazel stool with nice vertical sun shoots.

If you want to plant other species in it's place you will need to first remove the thorn - otherwise it will out compete the small sapling as you suggest.

Blackthorn and Hawthorn have their place and can be useful plants.
A blackthorn walking stick will outlast many.
