How to Deal With an Overgrown Garden

An overgrown garden can feel impossible. You look out the window, see a jungle where a lawn used to be, and don't know where to start. I get calls about this all the time — and the first thing I tell people is that it's rarely as bad as it looks. With a clear approach and a bit of patience, even the most neglected garden can be brought back.

Cornwall doesn't help matters. The mild, damp climate means our gardens never truly stop growing. There's no hard winter frost to knock things back the way it does in other parts of the country. Brambles, bindweed, nettles and rank grass can go from manageable to overwhelming in a matter of months if the garden isn't kept on top of. Add in the Atlantic rain that keeps everything green year-round, and you've got conditions that can turn a garden wild very quickly.

Why Gardens Get Overgrown in the First Place

Before you start hacking away, it's worth understanding why the garden got to this state — because it affects how you should approach it. The most common reasons I come across include:

• Bereavement or illness. Someone has been caring for the garden for years and has passed away, or a health problem has meant they simply couldn't keep up with it. In these situations, the garden may have been well-maintained before but has been left for a year or two.
• Moving into an inherited property. You've taken on a house from a relative or through probate and the garden hasn't been touched in years. There may be valuable plants and shrubs underneath the chaos — it's worth being careful about what you remove.
• A busy life. Work, family, travelling — it's easy to let a season slip. A couple of missed cuts in spring can quickly become a full overgrowth problem by summer.
• Cornwall's climate. As I mentioned, the growing season here genuinely is longer. If you're used to gardening somewhere in the north of England, the pace of growth in Cornwall can catch you off guard.

The First Step Is Assessment, Not Action

The instinct when faced with an overgrown garden is to grab the nearest tool and start cutting. Resist that urge. The most important thing you can do first is walk around and take stock.

Look for what's worth keeping. Hidden underneath brambles and rank grass, there are often established shrubs, hedges, fruit trees and ornamental plants that have real value. Cutting everything back to the same level without identifying these first means you might end up removing plants that took decades to grow.

Ask yourself:

• Is there a lawn underneath this grass — or has the turf been completely taken over by weeds?
• Are those large shrubs in the corner overgrown or dead? (Prod them — deadwood snaps, live wood bends.)
• Can I see any boundary hedging that might just need a hard cut-back?
• Are there any hazards I need to be aware of — trip hazards underfoot, old broken glass, rusted metal, concrete rubble?

Taking photos before you start is genuinely useful. It helps you see progress, and it gives you a record if you're planning to get a professional in to quote.

The Right Order to Tackle an Overgrown Garden

Approach it in this order and you'll avoid making extra work for yourself:

1. Clear rubbish and debris first. Old pots, broken garden furniture, bags of compost that have split, general rubbish — get all of this out of the way before you do anything else. You need to be able to see the ground and move around safely.

2. Cut the grass. Even if it's very long, getting the grass down gives you back a sense of control quickly and lets you see what you're dealing with in the beds and borders. If the grass is very long (over 15–20cm), you may need to use a strimmer first and then follow with a mower. Don't try to cut it all to lawn height in one go — take it down in stages.

3. Tackle the weeds. Now you can see what's a weed and what isn't, start removing them — starting with the most aggressive spreaders. Brambles and bindweed are the two you want to deal with first (more on these below). Nettles are easy to pull but wear gloves. Annual weeds can often be hoed off at the surface.

4. Prune overgrown shrubs. Most shrubs can handle a harder cut than you'd think. If they're just overgrown rather than diseased or dead, a good cut-back in late autumn or early spring will usually rejuvenate them. The key is knowing which shrubs flower on old wood versus new — cutting at the wrong time can mean missing a year of flowers, but it won't kill the plant.

5. Restore the beds and borders. Once the worst of the weeds are out and the shrubs are cut back, you can start to re-edge the beds, add mulch to suppress future weed growth, and assess what replanting might be needed.

What Can Be Saved and What Has to Go

Not everything in an overgrown garden is worth keeping — and knowing the difference saves a lot of time.

Brambles must be removed completely. Cutting them back above ground is not enough — the roots will send up new growth within weeks. You need to dig out the root ball or treat with a suitable weedkiller applied to the cut stem immediately after cutting. In Cornwall, brambles are one of the fastest-colonising plants you'll encounter.

Bindweed is similar — the white rope-like roots go deep and break easily, with each fragment capable of growing into a new plant. Repeated removal over a full season is usually needed to get on top of it.

Established hedges that look dead may simply be dormant or dormant under thick growth. Many hedging plants — including privet, laurel and even leylandii — can be hard cut back to old wood and will regenerate given time. If in doubt, don't rip it out.

Old fruit trees that look gnarled and neglected can often be brought back through careful pruning over two or three seasons. A tree that hasn't been touched for ten years doesn't need to be felled — it needs a specialist prune.

The Dangers of DIY Clearance

I don't say this to put you off doing it yourself — but there are some real risks to be aware of with an overgrown garden:

• Hidden hazards underfoot. Long grass hides all sorts — broken paving, old wire, holes in the ground, uneven steps. Walk the area carefully before you start working in it.
• Back injury from heavy lifting. Moving large piles of cuttings, shifting old shrub roots, hauling away bags of debris — this is heavy, repetitive work that causes injuries if you're not used to it.
• Waste disposal. This is a real practical issue. A clearance generates a huge amount of green waste — far more than a standard green bin can take, and many councils in Cornwall have limits on what they'll collect. Hiring a skip or van to take waste to the tip costs money and needs planning in advance.
• Nesting birds. Between March and August, always check before you cut back any large shrub or hedge — active nests must be left undisturbed by law.

What My Garden Clearance Service Involves

When I take on an overgrown garden clearance, I start with a free visit to assess the garden in person. Every overgrown garden is different — some need a single day's work, others need a phased approach over several visits.

I'll talk through what you want to keep and what needs to go, give you an honest assessment of what's worth saving, and agree on a plan before any work starts. Waste removal is included — I'll take everything away, so you don't need to worry about skips or tip runs.

For larger gardens or particularly overgrown sites, a phased approach often works best. We tackle the most urgent areas first — getting the lawn down, removing the worst of the weeds and brambles — and then return to do the finer clearance work once the garden is more manageable.

When to Call in a Professional

Some clearance jobs are genuinely suitable for doing yourself — a garden that's had one missed season, where the grass is long but the weeds haven't established, and where the waste volume is manageable.

But if any of the following apply, it's worth getting a professional in:

• The garden has been neglected for more than a year
• There are established brambles, bindweed or Japanese knotweed present
• There are large shrubs or trees that need cutting back
• You're not sure what's a plant worth keeping and what's a weed
• The volume of waste is more than you can deal with
• You have any physical limitations that make heavy work risky

The satisfaction of getting a neglected garden back under control is real — and whether you do it yourself or bring in help, the end result is worth the effort. If you're based in Cornwall and would like me to take a look, I'm always happy to come out for a free no-obligation visit and give you an honest assessment of what the job involves.
