Pruning a beech hedge
 

This Beech hedge is approximately two and a half years old and approx.2ft 6 inches high.

Someone mentioned that it needs cutting back in order to thicken or 'stool' it i.e. get side shoots to grow in order to thicken it.

Some native species - hawthorn, blackthorn and holly have been planted in between but these do not seem to be prospering. Someone told me that Beech is quite dominant and will 'poison' other species in its vicinity.

Could someone possibly give me detailed instructions on how to cut the hedge back and thicken it out etc? Also, could it do with a mulch of well rotted farmyard manure?

Thanks in advance-image links below:

Update:

I've pruned the hedge but noticed that some of the plants have been planted with the side shoots vertically positioned rather than horizontally so they will grow towards each other to form a hedge.

Is there any need to dig them up and turn them ninety degrees or will they eventually develop side shoots horizontally and join to form a hedge?

If need be, is it too late to dig ?

Thanks in advance.
