8 eco-friendly gardening tips for a greener sustainable garden

It’s National Gardening Week (1st-7th May) and with the weather warming up, it’s time to get outside and get your garden spring ready. As more and more people are becoming climate conscious and focused on helping the environment, there’s been a significant rise in sustainable gardening. Sustainable or eco-friendly gardening consists of practices that enhance your garden and cause no harm to the earth and its inhabitants.

Having an eco-friendly approach to your garden can make a huge difference to your outdoor space, including how it looks, how it functions and what it attracts. With this in mind, we spoke to Antoinette Jackson, founder of SuperBee.me who said that “by following eco-friendly gardening practices, not only do you create a beautiful, sustainable space, but you also take steps to minimise waste and reduce your carbon footprint. It's a win-win for both gardeners and the planet."

To find out more, Jackson gave us 8 eco-friendly gardening tips that are easy to implement and will leave your garden greener and more sustainable.

Before you get started, make sure you have the best equipment at your disposal, including the best garden tools to tackle all horticultural tasks, the best cordless lawn mower for grass maintenance and the best gardening gloves for hand protection.

1. Create a compost system

First on the list is to create your own compost system. If you’re new to gardening, “composting is the natural process of recycling organic waste, such as kitchen scraps and yard trimmings, into nutrient-rich compost for your garden,” says Jackson. In the spirit of ‘waste not, want not’, composting is a great way to reduce the amount of waste sent to landfills while also providing plants with essential nutrients. It’s also incredibly easy to do, so “to create a compost system, designate a corner of your garden for a compost pile or use a compost bin to speed up the decomposition process.” Find our top picks for the best compost bin to get started.

2. Plant diverse crops & native species

To keep your garden healthy, eco-friendly and looking beautiful throughout the seasons, plant diverse crops and native species. According to Jackson, “planting a variety of crops creates a more visually appealing garden and helps maintain soil fertility and prevent pest problems.” Similarly, native plants that are well adapted to local conditions often require “less water, fertiliser and pesticides, meaning you can conserve water, minimise chemical use and create a habit that supports local wildlife and attracts beneficial pollinators.”

3. Consider crop rotation & companion planting

Rotating your crops each year and companion planting are two ways to help your garden thrive in an eco-friendly way. Crop rotation helps “prevent soil depletion and reduce the risk of pests and diseases”, both factors that can lead to plants dying and soil losing its nutrients. Rotating your crops is a great way to avoid this and keep your plants and their insect friends happy.

Another tip is to start companion planting where you plant different plants in proximity to one another. There are many benefits to companion planting, as it can “help improve nutrient uptake, deter pests and increase pollination”, while also reducing the use of unnatural pest control measures and maximising your garden space.

4. Try vertical planting

Another eco-friendly planting tip is to grow your plants vertically. Introducing wall planters, hanging baskets, trellises and living walls to your garden expands your outdoor space and allows you to grow more in different areas of your garden. In addition to making your garden look more green and attractive, vertical planting can also “help improve air circulation and sunlight exposure, leading to healthier plants.”

5. Get mulching

Once you’ve planted your seeds or pruned your existing plants, give them a generous mulching. Jackson recommends “applying a layer of organic mulch, such as wood chips or straw, around your plants to retain moisture, regulate soil temperature, and suppress weed growth.” Mulching also helps conserve water, adds nutrients to soil and reduces soil erosion.

6. Choose organic, chemical-free pest control solutions

After you’ve put in the work to your garden, it can be annoying when your plants are invaded by aphids, earwigs and other common garden pests. To help keep these visitors at bay and away from your garden, Jackson says to “avoid using synthetic pesticides and opt for organic methods to control pests. Instead, introduce beneficial insects, like ladybugs and lacewings, to control pests naturally. You can also use homemade remedies, like a mixture of water and soap, to deter insects.”

7. Collect rainwater for irrigation

During spring and summer, your garden needs more water to deal with the hot temperatures. But the constant watering of your grass can be wasteful and rack up your water bills. Instead,  “collect rainwater in barrels or other containers, as it’s a free, natural resource that can help you conserve water. Additionally, rainwater is free from chemicals found in tap water, making it healthier for your plants.” Alternatively, having the best garden watering system can take care of watering your plants for you and you can set up schedules and timers so you’re not wasting water.

8. Use solar-powered garden lights

To light up your garden while reducing your electricity consumption, invest in solar-powered garden lights. “Solar lights charge during the day and automatically turn on at night, providing eco-friendly and cost-effective illumination,” says Jackson. See our guide to the best outdoor solar lights for our top picks. Another way to save money and cut down your energy usage is to invest in smart outdoor lighting. Options like the best Philips Hue outdoor lights can be easily customised so they only run at a certain time and use the lowest levels of brightness.
