Hedge Planning Questions Checklist

List the jobs the hedge has to do — enclosure, privacy from one particular window, keeping a dog in, filtering wind, a green edge — then rank them.

Ranking matters because those jobs pull against one another, and a nursery or designer has to know which of them the hedge is allowed to fail at.

Note which positions you want screened and stand in each of them, since the height a hedge needs depends entirely on where it is being judged from.

Screening from a ground-floor seat and screening from an upstairs window are different requirements, and only one of them may be achievable.

Consider whether the hedge is expected to stop anyone or anything getting in or out, and say so plainly, because that changes the whole proposition.

A hedge expected to contain or exclude has to be planned that way from the start, and it is rarely something that can be added afterwards.

Whether planting can act as a barrier, and what it would have to withstand, is a matter for a qualified professional; nothing here makes any hedge secure.

Record whether the hedge is expected to do anything about noise, and ask directly what planting can and cannot do about sound before relying on it.

Planting more often changes how much a noise is noticed than how loud it is, and that distinction is worth hearing from a professional first.

Note whether you want the hedge to read as a clipped face or a loose informal band, since that decides both the ground it takes and the work it makes.

The two are different propositions in width, in cutting and in appearance, and briefs often assume one while describing the other.

Write down whether the hedge is also expected to mark the boundary itself, because that is a separate question from screening and carries different consequences.

A hedge planted as a screen and a hedge planted as a boundary marker are treated differently by everybody involved, including future occupiers.

Where a boundary actually runs, and who owns a hedge standing on it, is a legal matter for your title documents and a suitably qualified adviser.

Walk the full length of any existing hedge on both sides where you can, and note where it is thin, bare at the base or dying back.

Faults concentrate in stretches rather than spreading evenly, and where they are matters more than how much of the hedge is affected.

Record how the hedge appears to have been managed, including whether one face has been cut regularly and the other left to grow.

A hedge cut on one side only tends to develop a lopsided form, and that history shapes what can reasonably be expected of it now.

Note where gaps have been filled with fencing, netting or a different plant, since patched hedges behave unevenly along their length.

Patches mark the places that have already failed once, and they usually indicate something about the ground or exposure there.

Record what grows up through or into the hedge from either side, and where it appears to enter.

Growth coming in from outside your plot is a different conversation from growth in your own bed, and the entry point tells you which it is.

What has grown into a hedge, and what should happen to it, is a question for a qualified horticultural professional to answer on site.

Note the height the hedge is kept at now and what it has been cut with, described by what you have seen rather than what you assume.

The current height reflects what somebody could reach with the equipment they had, which is useful information about future upkeep.

Consider whether you are trying to improve the hedge you have or replace it, and be clear which conversation you are starting.

These lead to entirely different discussions, and starting one while intending the other wastes the visit and the goodwill.

Mark on your sketch how wide a band of ground is available along the line, judged against everything else that has to fit past it.

A hedge squeezed into a strip that suits the drawing rather than the plant is the origin of most later complaints about it.

Note what runs alongside the line — a path, a drive, a lawn edge, a parking space — and how much of it a mature hedge would reach over.

The usable width of whatever runs beside a hedge shrinks as the hedge fills out, and that loss is rarely allowed for at the start.

Record whether anything is buried along the line, including drains, cables, a soakaway or a shared service, and ask before any digging is planned.

A hedge line is a long trench through a garden, and it crosses more buried things than a single planting hole ever would.

Where anything runs along or under a boundary line has to be established by the relevant provider before a trench for a hedge is planned.

Note where the line runs close to a wall, a fence post, a building or a paved edge, and raise each of those rather than assuming it is fine.

Position against built elements is a constraint owners rarely think to mention until something lifts, cracks or has to be cut back hard.

Planting close to structures, drains and boundaries should be discussed with a qualified professional before any position is fixed.

Consider what will be growing on the other side of the line, since a hedge with a border, a lawn or a neighbour's shrubs against it behaves differently.

Competition and shade at the base come from both sides, and the far side is often the one nobody looks at while planning.

Note whether the ground along the line is even, or whether it dips, slopes, or changes from wet to dry as it goes.

A long run frequently crosses more than one set of conditions, which is why hedges so often establish unevenly along their length.

Note where a person would stand to cut each face, and whether that ground is level, planted, paved or on the other side of the boundary.

Standing room decides whether a hedge gets cut properly or gets cut from whichever side is easy, which is how lopsided hedges begin.

Consider whether the far face can be reached without stepping onto a neighbour's land, and raise that question before the hedge goes in.

An agreement about access is straightforward to reach in advance and awkward to raise once the hedge has grown out of reach.

Access onto a neighbour's land is something to agree with them beforehand; where the position is unclear, take advice from a suitably qualified adviser.

Record whether the upper face could be reached from ground level at the height you intend to keep the hedge, or whether working at height would be involved every time.

The intended height quietly determines who can maintain the hedge and with what, and that is worth settling before it is planted.

Work at height and the equipment used for it belong with a qualified professional; do not plan a hedge on the assumption that somebody will manage.

Ask who will cut the hedge, and check that person is willing before the length of the run is decided.

The length of hedge somebody is prepared to cut is usually shorter than the length an owner is prepared to plant.

Note where the cuttings would go each time the hedge is cut, and whether there is anywhere on the plot to put them.

A hedge produces a large volume of arisings every cut, and having nowhere to put them is a common reason cutting gets postponed.

Consider whether a machine could reach the whole run, or whether part of it would have to be done by hand because of a slope, a step or a narrow gap.

The awkward stretch is the one that gets left, and identifying it now allows the design to change while that is still easy.

Ask what the hedge will look like when it goes in and how it is expected to change before it closes into a continuous face.

The gap between what arrives and what was pictured is the single most common disappointment in hedge planting.

Note whether you can tolerate an open gappy line while the hedge fills out, or whether something temporary is needed in the meantime.

Deciding this in advance avoids a rushed fence going up alongside a new hedge and then having to come out again.

Ask what watering the new hedge will need while it establishes, who will do it, and how water would reach the far end of the run.

Uneven watering along a long run can produce uneven establishment, and the far end is usually the part that suffers.

Watering needs vary with the site and the planting, and should be confirmed with a qualified horticultural professional rather than assumed.

Record what will be growing right up against the young hedge, since competition at the base is a common reason a run establishes unevenly.

Grass or a border pushed hard against a new hedge can take water and light from exactly the place the hedge needs both.

Ask what could damage the base of a young run at ground level, and agree who is responsible for putting any guard or barrier back once it is knocked over.

Damage at the base of a young hedge often shows for a long time afterwards, because the plant does not simply grow past it.

Settle in writing who makes good losses along the run, and how a visible difference in size between the original planting and any replacement would be handled.

Replacements planted later usually stay visibly behind the rest, and how that is handled is much easier to agree before it happens.

Talk to your neighbour before a hedge goes in on or near a shared line, and write down what was agreed while the conversation is fresh.

A hedge affects both sides for a very long time, and an early conversation is remembered far more warmly than a late one.

Confirm locally whether any requirements apply to hedge height, position near a highway, or sightlines at an entrance or junction.

Requirements of this kind vary from place to place and cannot be assumed either way from what neighbouring gardens have done.

Only the local authority can confirm what applies to hedges, boundaries and highway sightlines at your address.

Note what light the hedge would take from a neighbour's window or garden as it grows, and raise it early rather than after a complaint arrives.

Light lost gradually is resented sharply, and the resentment is much harder to answer once the hedge is established.

Record who has cut which side historically, since long-standing practice shapes expectations even where it settles nothing formally.

What has always been done is the first thing either side will cite, so it is worth writing down accurately at the outset.

Agree how growth crossing the line will be handled, and what either side will do before cutting anything back.

Most hedge disputes start with cutting that was reasonable in itself but arrived without warning.

What either side may cut, and what happens to the cuttings afterwards, is a legal question for a suitably qualified adviser.

Note whether the hedge would overhang a pavement, a shared path or a parking space used by others.

Growth over shared ground becomes somebody else's problem quickly, and it is usually raised by complaint rather than conversation.

Ask what wildlife the hedge is likely to support, and confirm locally what that means for when it may be cut or removed.

Timing restrictions can apply to hedge work in many places, and they are the sort of thing owners discover after arranging the work rather than before.

Nesting birds and other wildlife may be protected; what applies and when must be confirmed with the relevant authority before any cutting is arranged.

Note whether the hedge forms part of a longer run across several gardens, since a continuous line often matters more than any single stretch of it.

Connected hedges function differently from isolated ones, and a gap cut in the middle affects more than your own plot.

Record whether the hedge appears old, mixed and varied in its make-up, and ask whether that changes what may be done to it.

Older mixed hedges are treated differently in many places, and appearance alone is enough reason to ask before assuming anything.

Older or mixed hedges can carry protection; status must be confirmed with the local authority before removal is even considered.

Ask when in the seasons this hedge would normally be cut, and consider how that fits with the way the household uses the garden.

Cutting arrives at a fixed point in the seasons regardless of what else is happening, and it is disruptive if nobody expected it.

Consider whether you want the hedge to flower and fruit, and accept that this affects both its appearance and how it has to be cut.

Flowering and fruiting can depend on how and when a hedge is cut, so the preference is worth stating before any cutting regime is settled.

Write down whether anything nests, shelters or feeds in the hedge as far as you have observed, and pass those observations on.

Owner observation over the seasons is genuine evidence, and it is the sort a visiting professional has no way of gathering.
