Why Does My Garden Look Messy? How to Make a Garden Look More Put Together

There’s a funny stage in gardening where you’ve bought plenty of nice plants, everything is reasonably healthy, you’ve mulched, weeded, edged the lawn... and somehow the garden still looks a bit ordinary.

Nothing is actually wrong with it.

It just doesn’t look like the gardens you save on Instagram.

So naturally, you buy another plant.

I see this all the time, and I reckon it’s one of the easiest traps to fall into because nurseries are full of individual plants begging to come home with you. You find a beautiful Salvia. Then a grass you’ve never seen before. There’s a Westringia over there with great foliage. Oh look, that one's flowering. You can definitely squeeze that in.

Individually, every decision makes perfect sense.

Collectively, the garden starts looking like everybody turned up to a party with a different dress code.

The problem usually isn't that you need better plants.

You need the plants you already have to start talking to each other.

The garden centre problem

There’s something you should know about shopping for plants.

A nursery encourages you to look at plants individually.

That's unavoidable. They're sitting in pots, often grouped by type, with labels telling you why each one is wonderful.

A garden doesn't work like that.

When you stand back and look at a garden, your eye isn't studying every plant individually. It reads shapes, repeated colours, layers, spaces, lines and patterns.

That's why a plant can be absolutely gorgeous in the nursery and add almost nothing to your garden.

It isn't a bad plant.

It just didn't have a job.

One of the biggest changes you can make to the way you buy plants is to stop asking:

“Do I like this?”

and start asking:

“What is this doing in my garden?”

That little question has saved me from many questionable purchases.

Not all of them, obviously. I still work in a nursery.

Repetition is probably what you're missing

If professional-looking gardens seem somehow calmer than yours, have a look at how often the same plants appear.

Then look at a typical home garden.

One of these. One of those. Something flowering. Something Nan gave us. A plant bought on holiday. Something from the clearance table that lost its label. Another thing that looked smaller when we bought it.

There is absolutely nothing wrong with collecting plants if that's what brings you joy. A collector's garden can be magnificent.

But if you're trying to create a garden that feels cohesive, repetition is one of the easiest ways to get there.

Take something as simple as Little Jess™ Improved Dianella.

One Little Jess tucked into a gap is a perfectly nice plant.

Repeat it five or seven times through a bed and it becomes a thread. Your eye spots the same foliage again and again and suddenly completely separate areas feel connected.

It's such a simple trick that people tend to underestimate it.

Landscape designers don't.

You don't need everything to flower

This one causes a lot of garden chaos.

We love flowers, so we keep adding flowering plants.

Pink here. Purple there. Red over there. Yellow because apparently that corner felt left out.

Then winter arrives, half of it stops flowering and we discover there wasn't much of a garden underneath.

A good garden should still have bones when the flowers disappear.

That's where foliage earns its keep.

Grey foliage from something like Grey Box™ Westringia can provide a completely different colour without producing a single dramatic bloom. Goldie Box™ Westringia can introduce a warmer foliage tone. The deep colour of Little Ruby™ can create contrast. Strappy plants such as Lomandra and Dianella change the shape of the foliage.

Suddenly green isn't just green anymore.

You've got dark and light, fine and broad, upright and spreading, soft and structured.

Flowers can then arrive on top of that.

They become the jewellery rather than the entire outfit.

Give the garden something solid to hang onto

Sometimes a garden looks messy because everything in it has roughly the same visual weight.

Lots of small flowering things. Lots of wispy foliage. Lots of plants doing lovely things individually but nothing holding the whole lot together.

It needs structure.

That doesn't necessarily mean a hedge.

It might be three repeated compact shrubs. A small tree. A clipped form. A repeated line of evergreen foliage. Something upright anchoring one end of a bed.

Compact Westringias are brilliant for this because their foliage gives you a fairly solid evergreen shape. Aussie Box™, Grey Box™ and Goldie Box™ can all perform structural roles, depending on the effect and growing conditions you're working with.

The important part isn't necessarily which shrub you use.

It's recognising that the garden needs something visually dependable.

Something that isn't having an identity crisis every season.

Then let something misbehave a little

This is where it gets fun.

Once you've got structure, you don't need everything else standing to attention.

In fact, you probably don't want it to.

Let Purple Fusion™ Scaevola wander towards an edge. Let Yareena™ Myoporum spread underneath taller planting. Let Meema™ Hardenbergia take up some room. Use the softer foliage of Lomandra or Dianella against compact shrubs.

A garden usually looks better when there's tension between order and looseness.

Too much order and it can feel sterile.

Too much looseness and it looks like everyone has been left unsupervised.

The sweet spot is somewhere in between.

Stop planting in ones

This doesn't apply everywhere, but it's a good rule to experiment with.

If you've got a reasonably sized garden bed and you're about to buy one small grass or one little groundcover, ask yourself what three would look like.

Or five.

Odd-numbered groups aren't some sacred horticultural law, but they can make informal groupings easier because your eye tends to read the plants as one mass rather than individual dots.

The other option is a larger repeated drift.

Imagine Tanika® Lomandra running through a planting.

Now imagine one Tanika.

Same plant.

Completely different effect.

One says, “I bought a Lomandra.”

The other says, “This was the plan.”

Don't confuse variety with interest

This took me a long time to properly appreciate.

You can have a garden containing thirty different plants that somehow looks less interesting than a garden containing six.

Because interest doesn't only come from the number of species.

It comes from contrast.

A broad leaf beside a fine leaf.

Dark foliage against silver.

A low spreading plant beneath something upright.

A soft plant beside a clipped one.

Movement against solidity.

That's why something like Blue Horizon™ Eremophila can be so useful in a predominantly green planting. Its foliage provides contrast before you even consider flowers.

The same goes for a dark grass, a variegated plant or a silver groundcover.

You don't necessarily need another species.

You might just need another texture.

Look at the shapes, not the plant names

Here's a little exercise I love.

Squint at your garden.

Seriously.

Don't focus on individual plants. Let everything go slightly blurry and look at the overall shapes.

Where are the big masses?

Where is the height?

Is everything the same height?

Is there one random tall thing floating in the middle?

Does the planting gradually move from one form to another, or does it look like twenty individual green blobs?

This is much closer to how we actually perceive a garden from a distance.

Now imagine adding something low and broad such as Mundi™ Westringia or Low Horizon™, something compact and rounded, then something upright.

You're designing with forms rather than names.

That's a much more powerful way to think about plants.

Sometimes the messy bit is actually the empty bit

This sounds contradictory, but stay with me.

A garden can feel visually messy because there are too many isolated plants surrounded by visible mulch.

Your eye keeps stopping.

Plant.

Gap.

Plant.

Gap.

Plant.

Gap.

Once appropriately selected groundcovers begin connecting some of those spaces, the garden can suddenly feel calmer.

That's where plants such as Yareena™, Purple Fusion™, Aussie Rambler™ or even Zen Grass® in the right situation can change the whole feeling of an area.

They create a ground layer.

You're no longer looking at twenty separate objects sitting in mulch.

You're looking at a planting.

That difference is enormous.

But please don't fix it by cramming plants together

This is where enthusiasm gets dangerous.

If repetition is good and covering bare soil is good, surely we should simply plant 400 things immediately?

No.

The plants are going to grow.

A new garden is allowed to look new.

In fact, it should have gaps if you've planted according to mature size.

This is why knowing the eventual width of a plant is just as important as knowing its height.

Give the structural plants the room they'll need later. Use genuinely lower-growing plants where another layer makes sense. Mulch the remaining spaces while everything establishes.

A garden filling in over two or three years is normal.

You haven't failed because it didn't look like Chelsea Flower Show six weeks after planting.

Edges matter more than people think

If your garden feels untidy, look at its boundaries.

Where does lawn finish and garden begin?

Where does groundcover stop?

Does a garden bed simply peter out into nowhere?

Is there a path or edge giving the planting a shape?

Plants can be informal while the underlying layout is quite clear.

In fact, that contrast often looks fantastic.

A crisp path beside loose planting.

A defined lawn edge with groundcover spilling slightly over it.

A strong garden-bed shape filled with soft grasses.

The structure doesn't always have to come from the plants themselves.

Sometimes the edge is doing half the design work.

Give the eye somewhere to stop

A garden where everything has equal importance can be exhausting to look at.

You need quieter bits.

And occasionally you need something that makes you stop.

Maybe that's a feature tree.

Maybe it's a grass tree.

Maybe it's a beautifully shaped shrub, a pot, a seat, a rock or something flowering spectacularly at a particular time of year.

Whatever it is, don't surround it with ten other things screaming for attention.

Let it have its moment.

This is another reason repetition works so well. Repeated planting becomes the supporting cast.

Then when something genuinely special happens, you actually notice it.

Before you buy another plant, try this

Walk outside and take a photo of the garden.

Photos are strangely unforgiving.

Things we stop noticing in real life suddenly become obvious on a screen.

Look for the plants that already repeat. Could you repeat them again?

Look at foliage colour.

Look at the heights.

Look at the bare areas.

Look for one plant that seems completely unrelated to everything around it.

Then ask yourself what the garden needs.

Not what plant you want.

What does the garden need?

Those are very different shopping trips.

How do you make a garden look professionally designed?

There isn't one formula, and there shouldn't be.

But the gardens that feel considered usually share a few things: plants have enough room to develop, forms are repeated, there is some kind of structure, foliage has been considered as carefully as flowers, and not every square metre is trying to be the main event.

Most importantly, the plants relate to one another.

That's really what good garden design is.

Not expensive plants.

Not having hundreds of varieties.

Not knowing every botanical name.

It's creating relationships between plants, space and the house around them.

You probably don't need more plants

I realise this is a questionable thing for an online nursery to tell you.

But there you go.

If your garden doesn't quite look right, don't automatically add something new.

Stand back first.

Repeat something that's already working. Give a feature plant some breathing room. Add structure if everything feels loose. Add softness if everything feels rigid. Look at foliage instead of chasing another flower. Cover the ground where it makes sense and leave deliberate space where it doesn't.

Then, if the answer genuinely is another plant...

Well.

Conveniently, we know a place.
