When the temperature drops, most gardens in Epsom and the surrounding Surrey areas suddenly look fragile. Pots crack. Shrubs brown overnight. Small trees that looked perfectly healthy in October can look half-dead by February.
The truth?
Frost damage is sneaky – and completely preventable if you get ahead of it.
Below is a practical winter garden guide so your pots, shrubs and small trees don’t just “survive”… they roll into spring ready to thrive.
Why frost is such bad news for plants
When frost hits, two things happen:
- Moisture inside plant cells freezes, expands and causes damage
- Roots get chilled, meaning they can’t pull in nutrients or water
Plants in the ground are usually insulated by surrounding soil.
Pots and containers? They’re exposed on every side – which is why they suffer first.
Which plants are most at risk?
In and around Epsom, the ones we see struggle most are:
- young shrubs
- olives, bay and small citrus trees in pots
- lavender in cold, wet soil
- borderline exotics (phormium, palm, cordyline)
- herbaceous plants left in shallow containers
If you’ve invested good money in your garden, don’t let winter undo it.
Simple ways to protect pots from frost
- Lift pots off the ground
Use pot feet or bricks so cold water can drain away.
Standing water + freezing nights = cracked pots and dead roots.
- Wrap the containers
Bubble wrap, hessian or fleece tied loosely around the pot works brilliantly.
You’re insulating the root ball – that’s what actually matters.
- Move vulnerable pots closer to walls
A house wall radiates a tiny bit of heat and blocks the wind.
Those few degrees often make the difference.
- Group pots together
Like penguins huddling in Antarctica. They protect each other.
Protecting shrubs through cold snaps
Shrubs rarely die overnight. They deteriorate gradually through repeated frost.
Do this:
- Add a 5–7cm layer of mulch (compost, bark, leaf mould)
- Avoid feeding – new growth is tender and frost will roast it
- Water occasionally during long dry spells (yes – even in winter)
And yes – the ugly garden fleece is worth it. It’s cheap, light, and keeps frost off delicate foliage without suffocating plants.
What about small trees?
Young trees, especially in exposed gardens, benefit from:
- trunk protectors or fleece wraps
- mulching around (but not touching) the trunk
- staking properly so winter winds don’t rock the roots loose
Tree rocking is a silent killer – roots break, water uptake stops, and the tree declines in spring. It’s avoidable.
Common winter mistakes (we see these constantly)
- Cutting everything back “to tidy it”
Many plants rely on their top growth as winter protection.
- Overwatering containers
Cold + soaked compost = root rot.
- Leaving delicate pots in exposed corners
Wind chill is as bad as frost.
When to bring plants indoors
Move tender plants into:
- a greenhouse
- unheated conservatory
- sheltered garage with light
If that’s not possible, double-wrap the pots and keep them close to the house.
Want peace of mind through winter?
If all this sounds like effort… it is. But it’s cheaper than replacing half your garden in April.
