These sustainable small garden ideas will inspire you to use your compact patio or balcony for so much more than sunbathing and barbecuing.

To help make the most of a passion for gardening no matter your garden's square footage, Uswitch have put together some small garden ideas and tips for transforming your tiny space into a self-sufficient haven... 

Sustainable small garden ideas

1. CREATE A WORMERY

Any organic waste you produce, such as fruit and veg scraps and garden greens, can be digested by tiger worms in a container, turning them into valuable compost. 

Worms can eat up to half of their own body weight each day, and their population increases rapidly under the right conditions, so emptying your bin regularly should become a thing of the past. Don’t worry, it doesn’t smell.

2. COLLECT RAIN WATER WITH A WATER BUTT

Whether you are looking for courtyard garden ideas or are lucky enough to have some lawn space, water butts are one of the simplest sustainable small garden ideas, as they reduce reliance on grid services. 

The back-to-basics approach of collecting rainwater is as old as humanity itself, and it’s surprising that not more of us have this as a facility, especially during the summer when hosepipe bans are rife. The lack of chlorine makes it ideal for watering plants - but not safe for us to drink ourselves.

3. HARNESS THE WIND

You don’t need a massive turbine in the garden to prove you’re an eco-warrior. An innovative design is expected to enable city dwellers the ability to harness the wind from their balconies. 

The winner of the 2018 Dyson Award, O-Wind is a small product that claims to make the most of multi-directional winds, making it an ideal roof garden idea or one for those in high-rises who need balcony garden ideas instead. Alternatively, you can purchase simple building-mounted turbines for a fraction of the cost of pole-mounted ones.

4. GROW YOUR OWN

No grass? No problem! Food can be grown in all sorts of containers to create a small vegetable garden – from raised beds, to crate pallets, hanging baskets, and plastic poly tunnels. 

In many ways these planters are better than a garden, as you're able to choose the quality of your soil and benefit from better drainage. Lettuces, tomatoes, and cucumbers are some of the simplest items to grow, where you’ll see the fruits of your labour within a few weeks, encouraging you to keep up the good work.

5. BENEFIT FROM A BIRD BOX

Adding birdhouses to your garden will provide a refuge for wildlife in any environment.

Especially in cities, where a lack of natural habitat in cities leaves many birds without areas to nest and lay eggs, providing this small space for them helps to protect their species. They’ll return the favour by keeping pests at bay, a necessity when growing your own food.

Taking these small steps to improve your outdoor space are a great way to start leading a more organic lifestyle. 

Even those in the city can reap the benefits of being more self-sufficient and put some sustainable small garden ideas into action. And with the mental health and well being benefits of gardening clear, there’s never been a better time to get started.
