Overgrown Garden: Where to Start

By the Property Maintenance Coventry team· 2026-10-27· 8 min read
The quick answer

Identify before you cut. Japanese knotweed, bamboo and mature trees all change the plan, and some trees are protected. Then work in order: survey, cut access, deal with woody growth, clear and remove, establish the boundaries, and only then decide the layout. Clearing in an arbitrary order means handling the same material twice.

Key takeaways
  • Identify knotweed, bamboo and protected trees before any cutting starts.
  • It is an offence to damage an active bird nest, which effectively restricts hedge work in spring and early summer.
  • Clear boundaries first. You cannot see the garden or fix the fence until you can reach it.
  • Do not plan the layout from memory of what the garden used to be. Plan it once it is clear.

Identify before you cut

This is the step people skip, and it is the only one that can turn a weekend into a legal or financial problem.

Four things to establish before a blade goes near anything.

Japanese knotweed

Hollow bamboo-like canes with reddish speckling, heart-shaped leaves alternating in a zigzag along the stem, and clusters of small cream flowers in late summer. It dies back to brown canes in winter and regrows fast from spring. Strimming or digging it spreads it, because fragments of rhizome regenerate. Soil containing it is controlled waste. If you suspect it, stop, do not cut it, and have it identified — treatment is a managed programme, not a clearance job.

Bamboo

Running bamboo spreads by rhizome, often many metres, and routinely crosses boundaries and comes up through patios and into neighbouring gardens. It is not a notifiable plant but it is a genuine problem and it has been the subject of neighbour disputes. Cutting the canes achieves nothing — the rhizome is the plant. Removal means excavating the rhizome mass, which is substantial work.

Trees, and whether they are protected

A tree may be covered by a Tree Preservation Order, or protected simply by being in a conservation area, in which case notice must be given before work. Felling or heavily pruning a protected tree without consent is an offence carrying a substantial fine. Trees also have roots near foundations and drains, and a large tree close to the house is a question for an arboriculturist rather than a clearance team. The local planning authority will confirm whether a tree is protected.

Nesting birds

It is an offence to intentionally damage or destroy the nest of a wild bird while it is in use or being built. In practice that restricts hedge and dense-shrub work through the nesting season, roughly March to August, with the main risk in spring and early summer. It does not stop all garden work, but it does mean checking a hedge before cutting it, and often means deferring hedge removal to autumn or winter.

Nothing on that list is exotic. Knotweed and running bamboo in particular turn up often enough in neglected gardens that checking is simply sensible.

The order of work

  1. Survey. Walk it, photograph it, note what the four items above turn up. Find the boundaries, the manholes, the stopcock, and any service runs. Mark anything worth keeping.
  2. Cut access. Clear a route in and a route to the boundaries. Until you can get round the garden you cannot assess or work on it.
  3. Reduce the woody growth. Brambles, self-seeded saplings, overgrown shrubs and ivy. This is the bulk of the volume and it is best dealt with before anything at ground level.
  4. Clear and remove. Get the material off site. Working around heaps of cut growth is how the same material gets handled three times.
  5. Sort the boundaries. With access cleared, repair or replace fences and walls now — while there is nothing in the way and no new planting to damage.
  6. Deal with the ground. Stumps, roots, levels, and whatever the clearance revealed. Expect to find an old path, a concrete base or a buried patio; neglected gardens usually have one.
  7. Then plan the layout. Not before. You now know the levels, the aspect, the drainage and the boundaries, and the plan you make will be about the garden that exists.

Steps four and five are the ones most often done in the wrong order. Replacing a fence before the clearance means working around the growth and then damaging the new fence getting the material out; replacing it after the planting means trampling the planting.

What you will probably find

DiscoveryWhy it mattersWhat to do
An old path or concrete baseAffects levels and new foundationsBreak out, or build the plan around it
A buried patio under turfDrains badly; grass over it will not thriveLift it, or expose and reuse it
A failed or missing fenceBoundary and privacy; cheapest to do nowReplace while access is clear
Ivy into brickwork or rooflineGets under tiles and into mortar jointsCut at the base; remove slowly
A tree too close to the houseRoots near foundations and drainsArboriculturist, not a chainsaw
A blocked gully or manholeStanding water and drainage problemsClear and check it runs
Severely compacted groundNothing will grow; water sitsDecompact before planting anything

The last row is worth taking seriously. A garden that has been under dense growth for years often has poor, compacted soil underneath. Planting into it without improving it wastes the planting.

Ivy, brambles and the things that come back

Clearance is not a single event with these, and anyone promising otherwise is overselling it.

Brambles regrow from the root crown. Cutting them to ground level removes the visible plant and the crown sends up new growth within weeks. Digging out the crowns is the difference between clearing brambles and cutting brambles, and it is considerably more work.

Ivy on a wall or into a roofline needs cutting at the base and then leaving to die before removal. Pulling live ivy off brickwork takes the mortar with it, and pulling it out of a roof dislodges tiles. Cut it, wait, then remove it gently.

Self-seeded sycamore, ash and buddleia coming out of walls and paving regrow from any remaining stump. Treat or grind the stumps, or accept they will return.

Bindweed, ground elder and horsetail regenerate from root fragments left in the soil. Rotavating a bed full of them multiplies the problem by chopping the roots into cuttings.

The realistic expectation is that the first year after clearance involves pulling regrowth, and that a garden is properly under control in its second season. That is normal rather than a sign something went wrong.

Mistakes Coventry homeowners keep making

  • Strimming first. If there is knotweed, strimming spreads it. If there are nests, it destroys them. If there are brambles, it achieves nothing lasting.
  • Rotavating a weedy bed. Perennial weed roots become cuttings. You have propagated, not cleared.
  • Planning the layout before clearing. The buried patio, the levels and the drainage all change the plan.
  • Burning or dumping the waste. Green waste goes to a licensed site, and soil containing knotweed is controlled waste with specific disposal requirements.
  • Pulling ivy off the house. It takes mortar and tiles with it. Cut at the base and wait.
  • Doing the fence last. It is cheapest and easiest while the garden is clear and empty.
  • Planting into compacted soil because the clearance looked like the hard part. It was not.

What it costs

These are the landscaping figures published across this site:

JobTypical Coventry guide priceNotes
Day rate£150–£250/dayPer landscaper
Landscaper, hourly£15–£40/hrTask dependent
Fencing£80–£150 per panelSupplied & fitted
Patio£80–£150 per m²Material dependent

Clearance is priced by the day plus disposal, because the volume of material is what drives it rather than the area. Waste removal is a real and often underestimated part of the cost on a badly overgrown garden.

Frequently asked questions

Where do I start with an overgrown garden?

Identify before you cut — Japanese knotweed, running bamboo, protected trees and active bird nests all change the plan. Then cut access, reduce the woody growth, clear the material off site, repair the boundaries while access is clear, deal with the ground, and only then plan the layout.

Can I clear a garden during nesting season?

Most of it, with care. It is an offence to intentionally damage or destroy a wild bird's nest while it is in use or being built, which in practice restricts hedge and dense-shrub work from roughly March to August. Check a hedge before cutting it, and defer hedge removal to autumn or winter where you can.

How do I know if I have Japanese knotweed?

Hollow bamboo-like canes with reddish speckling, heart-shaped leaves zigzagging along the stem, cream flowers in late summer, dying back to brown canes over winter. If you suspect it, do not cut or dig it — fragments regenerate and the soil becomes controlled waste. Get it identified first.

Why do brambles come back after clearing?

Because cutting removes the visible plant and leaves the root crown, which sends up new growth within weeks. Digging out the crowns is the difference between clearing brambles and cutting them, and it is considerably more work. Expect to pull regrowth through the first season either way.

Should I strim an overgrown garden first?

Not as a first move. If there is knotweed, strimming spreads it; if there are nests, it destroys them; and on brambles it achieves nothing lasting. Survey first, cut a route in, then work through the woody growth deliberately.

Can I pull the ivy off my house?

Not while it is alive. Pulling live ivy off brickwork takes the mortar with it, and pulling it out of a roofline dislodges tiles. Cut it through at the base, leave it to die back, then remove it gently. It takes longer and it costs far less than the repairs.

Identify first, then clear

We survey before quoting, because knotweed, bamboo or a protected tree changes the job completely and all three turn up in neglected gardens.
