How to Get Your Garden Ready for Summer Colour

By May, most gardeners are ready to start looking ahead. Spring has brought fresh growth, blossom and early flowers, but now the focus begins to shift towards summer. This is the month when you can start preparing the garden for a fuller, more colourful and more inviting season ahead.

The best thing about getting your garden ready for summer colour is that it does not have to mean starting from scratch. In fact, a few well-timed changes in May can make a remarkable difference. Refreshing pots, filling gaps in borders, planting long-flowering favourites and paying attention to shape and balance can all help the garden feel more vibrant over the weeks ahead.

In the UK, May is a key month for planting, tending containers, protecting tender plants if needed and preparing the garden for stronger summer growth.

For Oxfordshire gardens, where spaces range from traditional village plots to family lawns and modern patios, May is the ideal time to bring structure and colour together.

Start by looking at the garden as a whole

Before buying new plants, take a little time to notice how your garden feels.

Where does it look empty?

Some parts of the garden may still feel sparse after winter and early spring. These are often the best places to target first.

Where would colour make the biggest difference?

Think about what you see from windows, where you walk through the garden, and where you spend the most time. These are often the most rewarding places to add more seasonal interest.

Refresh pots and containers

If you want quick results, containers are one of the fastest ways to make the garden feel brighter.

Update spring displays

Some spring pots may still look lovely, while others may be beginning to fade. May is a good month to refresh them gradually with plants that will carry the display forward.

Bring in more summer colour

Towards the end of the month, summer bedding and stronger flowering plants can begin to take over in baskets and containers, especially in milder or sheltered gardens.

Do not forget hanging baskets

Hanging baskets help add colour vertically and make patios, doors and walls feel more layered and complete.

Fill gaps in borders

One of the simplest ways to prepare for summer colour is to look for spaces in borders that need strengthening.

Add long-flowering perennials

Plants such as salvia, hardy geraniums and verbena bonariensis can help build summer impact while still looking natural and garden-friendly.

Use foliage for contrast

Flowers matter, but foliage is what often makes a planting scheme feel rich and balanced. Heuchera and compact shrubs can be especially useful here.

Repeat colours for a more polished look

If you use similar tones in more than one part of the garden, the whole space feels more joined up and intentional.

Think in layers

Gardens that feel colourful and successful usually have more than one level of interest.

Low planting

This softens the front of borders and helps beds feel full.

Mid-height planting

This often provides the main colour and volume.

Taller accents

Plants with vertical growth or airy stems add movement and stop borders feeling flat.

Plant for longer-lasting colour

One of the best ways to improve a garden in May is to choose plants that will continue performing well into summer.

Choose reliable performers

Good summer colour often comes from dependable plants rather than overly complicated combinations.

Mix flowers, herbs and shrubs

A garden feels more interesting when it includes useful and fragrant plants as well as ornamental flowers.

Support pollinators at the same time

Summer colour and pollinator-friendly planting work beautifully together.

Include nectar-rich flowers

Plants such as lavender, salvia and thyme can add colour while also helping bees and other pollinators.

Let the garden feel alive

A colourful garden feels even more successful when it has movement and wildlife within it.

Tidy and prepare without overdoing it

May is a good month for light, purposeful maintenance.

Remove faded growth

Clearing away what has finished makes room for stronger new planting.

Feed and water where needed

If plants are to perform well through summer, they need a good start now. Containers especially benefit from regular attention.

Stake plants early

Some taller plants are easier to support before they become too large and floppy.

Use colour around key areas of the garden

Front doors and entrances

A few well-planted pots can change the whole feel of the entrance to your home.

Seating areas

Colour and scent near places where you sit make the garden more enjoyable to spend time in.

Paths and focal points

Placing brighter planting along routes through the garden helps the whole space feel more alive.

Make small gardens feel fuller

Even in compact spaces, summer colour can be made to feel generous.

Use vertical planting

Hanging baskets, wall planters and climbing plants help small spaces feel more layered.

Keep the palette controlled

In smaller gardens, a slightly simpler colour palette often looks more stylish and less cluttered.

Use containers for flexibility

Containers let you move colour around as needed and make the most of every bit of available space.

Plan now for a better summer garden

The most beautiful summer gardens are often shaped in May. This is when the foundations are laid, the gaps are filled, the containers are refreshed and the seasonal direction becomes clear.

You do not need to transform everything at once. Often, the best results come from making a few thoughtful changes in visible areas and building from there.

Bring your garden into its next season

If your garden still feels a little too spring-like or slightly unfinished, May is the perfect time to guide it towards summer. Refresh containers, fill empty spaces, choose reliable flowering plants and create a garden that feels ready for the months ahead.

Learning how to get your garden ready for summer colour is really about noticing what your space needs and responding with simple, practical improvements. A few well-chosen plants and some thoughtful positioning can make all the difference.
