Quick Answer
What buyers notice first in a neglected garden: overgrown lawn, broken fences, bramble patches, rubbish and clutter, dirty patio, dead plants, and overgrown hedges. These are the top 7 turn-offs that reduce the sale price. In the Chilterns, where buyers are discerning, a neglected garden can knock 5 to 15 percent off the sale price.
Why First Impressions Matter
When a buyer arrives at a property, they form an opinion in the first 30 seconds. The garden is a major part of that first impression. A tidy, well-presented garden says "this property is cared for". A neglected garden says "there are problems here". Once a buyer has formed a negative opinion, it is hard to change it.
In the Chilterns, where property values are high and buyers are discerning, a neglected garden is particularly damaging. Estate agents in Marlow, Henley, Beaconsfield and Amersham tell us that a neglected garden is one of the top three things that put buyers off. This guide explains what buyers notice first in a neglected garden, so you can fix the problems before marketing.
The 7 Things Buyers Notice First
1. Overgrown Lawn
An overgrown lawn is the most obvious sign of neglect. It suggests the whole property has been neglected, not just the garden. Buyers wonder what else has been neglected (the boiler? the roof? the drains?). Fix: mow and edge the lawn before the photos.
2. Broken Fences
Broken fences suggest the property is not maintained. They also make the garden feel less private and secure. Fix: repair or replace broken fence panels. See our fencing service.
3. Bramble Patches
Bramble patches are a clear sign of neglect. They look like a lot of work to clear, which puts buyers off. Fix: clear brambles before listing. See our bramble clearance guide.
4. Rubbish and Clutter
Rubbish and clutter (old furniture, broken toys, building materials) make the garden look neglected and reduce the apparent size. Fix: remove all rubbish and clutter. Hire a skip if needed.
5. Dirty Patio
A dirty, mossy patio looks neglected and is a safety hazard. It also makes the garden feel smaller. Fix: sweep and pressure wash the patio. See our pressure washing service.
6. Dead Plants
Dead plants in the borders suggest the garden is not cared for. They also make the garden look untidy. Fix: remove dead plants and replace with healthy ones.
7. Overgrown Hedges
Overgrown hedges make the garden feel smaller and darker. They also suggest the property is not maintained. Fix: cut hedges to a neat shape. See our hedge cutting service.

- Spending on the wrong things. Fix the obvious problems first. Do not spend on expensive landscaping.
- Leaving it too late. Allow 2 to 4 weeks before the photos for the fixes to look their best.
- Not clearing the front garden. The front garden is what buyers see first. Make sure it is tidy.
