Sure, the big gardens are Chelsea Flower Show's ultimate showstoppers, but we argue that for most homeowners, the real magic happens in the balcony and container gardens. These clever designs are inspiring reminders that even the smallest spaces have big potential. Browse this year's round-up below, packed to the brim with ideas that are both pretty and practical.
All the designers of the Balcony & Container Garden category are making their Chelsea debut this year. Their designs range from wildlife-friendly spaces to nostalgic, rose-filled gardens created with large reclaimed pots and vessels – as seen in the Whittard of Chelsea Garden – to practical, space-saving solutions featuring foldable furniture and corner planters, showcased in the Transient Garden.
To try these ideas at home, the RHS recommends the following:
For balcony gardening
Check the weight loading of your balcony - this is usually calculated at 70kg per mz
Limit weight by using lightweight potting media and containers
Place heavy containers near load bearing walls or joists
North-facing balconies can be dark and dry, south-facing balconies can be very bright, so are unsuited to shade loving plants
For container gardens
Use big containers where dryness and breezes are expected
Choose drought resilient plants such as succulents, grey-leaved plants and hardy palms for sunny spots
Feed pots with liquid fertiliser such as seaweed fertiliser every week in summer
Switch seasonal plants throughout the year to ensure nonstop colour.

Alzheimer’s Society: Microbes and Minds Garden
Josh Kemp-Smith
This container garden aims to raise awareness of the increasingly well-evidenced link between gut health and brain function. Inspired by the process of making apple cider vinegar – renowned for gut health benefits – the design centres on an apple tree representing 'The Mother', the naturally occurring culture of bacteria formed during fermentation. A high-gloss sculpture curves protectively around the tree, sheltering both 'The Mother' and the person sitting on the bench within.

RHS / Josh Kemp-Smith
The angels' share is the portion of whisky lost to evaporation as it's left to age in oak casks. This balcony garden draws on the poetic language of whisky-making, using planting designed to attract endangered native pollinators – species that are themselves at risk of becoming part of the angels' share.

The Whittard of Chelsea Garden
Josh Kemp-Smith
Celebrating 140 years of Whittard, this nostalgic container garden is created using only reclaimed or recycled materials, from the pots to the paving and gravel, made from cockle shells collected from the bank of the Thames. If this design, full of scented roses and trailing foliage, proves one thing, it's that large containers definitely belong in a small garden.

The most colourful of all the balcony and container gardens, this modest design is a striking example of how effectively colour can transform a space. Beyond containers overflowing with vibrant blooms, there is little else – proving that even with limited means, bold use of colour can have a dramatic impact.
