Agreed - good points.
One has a choice of Bare-Root or Containers.
1. Bare Root.
One is basically; -Creating a trench 0.9 metres wide, with that 1st row
of stems 10.5" in from the side;15" between the 1st & 2nd rows & then a
final 10.5" to the near-side. The depth of the trench should be;- "The
depth to the bottom of the (bare) roots of the plants " I'd believe
that that depth should not need to be deeper than
12"/30cm to get to that depth.
I'd also believe that existing grassroots would be found at that depth.
2. Containered.
Never regard container-grown plants as an easy-option - an option in
that one might be led to believe that one can 'get-away-with' simply
planting pots in separate holes. I wouldn't recommend NOT creating a
trench when one is trying to create any hedge.
Because - between each plant is being left compacted,uncultivated earth
which will also contain grass roots + maybe other 'weed'-roots. This is
leaving both 'competition' & 'compaction'.
If one has decided to create 'separate' planting holes instead (
actually a longer work-process than setting-out the pots in the trench,
incidentally ) - then assuming it's "clean" holes, - ("cleaned" of
stones/roots etc - including any existing roots-of trees - would still
be severed. To give the best start to the new plantings,( which of
course isn't taking into
account those Tree Roots.) [I appreciate this dilemma of trying to
accommodate the tree & the hedge together ]
It's also good practice to ensure that the holes should BOTH be (a)
having the Top of the soil-ball of the Container/ed)
Plant is 1" ( 25mm ) below the surrounding soil surface & (b) AND have a
further 3"- 4" layer of planting-mixture(soil, bone-meal +
organic-matter e.g.leaf-mould) - UNDERNEATH the
level-of-the-bottom-of-the-pot.
This tells me that such any 'typical' pot-grown plant-planting-hole is
- or SHOULD be - the same/even deeper than any
'typical' bare-root plant.
If the plant is to carefully integrate containers-(containers-in-which
any subject COULD BE GROWN - but containered/
/container-grown Beech will STILL be cheaper than Box) planted
roughly-in-line ( to miss those tree - roots )
- then yes - there WILL be less damage to those existing Tree Roots.
The key phrase is 'carefully integrate'.
If you use a single-line of Bare-root is would be MORE EASILY 'carefully
integrated' between those existing Tree Roots.
In that case I'd decrease that gap-between-plants down from 18" to 15"
(30cm).
Don't forget to herbicide the grasses - this is the major-competitor to
the Hedge rather than the Tree(s) . And then 'top' with a 3" (75mm)
mulch of Dead Leaves, after the initial Good-watering.
I'd suggest Fagus will be better than Buxus with regard to
shade-tolerance.

Subject: RE: Underplanting new trees
<I'd recommend a staggered/double-row of plants (40-60 Bare-Roots ) -
planted 18" / 45cm apart between plants-in-the-row & 15" / 30cm between
rows. (This works out to 5.25 plants/lin.metre )>
Beech, good choice, but just realised from Alan's first posting
'underplantng beneath street trees'. Would these trees be growing within
narrow strips of land along the roadside where the majority of roots are
going to be found eitherside of the stem beneath the verge! Any planting
within the verge would probably destroy the already confined tree roots.
So staggered planting, excavation etc here would appear to be a most
destructive activity for the trees.
