There’s been a lot of coverage of the climate crisis over the past few months, and it’s fantastic that awareness is growing. But how can you do your bit in the garden? Here’s 15 ways you can garden more sustainably to help our planet!
How many of these do you do already?
Be Smart With Seeds
you can save resources and money by keeping the seeds from your flowers such as the cowslip pictured, as well as fruits and vegetables to use the following year. Be sure to dry them out before storing and then keep in a breathable container. If you end up with a surplus of seeds, look for your local seed swap event and see what you can exchange them for.
If you collect seeds from primulas, it is a good idea to scarify them before sowing to speed up the germination process.
Ditch the Peat
Whilst peat is great for growing plants, it comes with a high environmental cost. Peat is extracted from peat bogs, destroying the unique biodiversity of this habitat. Peat bogs are also an excellent carbon store – turning decomposing plants into peat thanks to the wet, anoxic condition of the bogs. When peat is harvested, green house gasses are released into the atmosphere, and once spread onto gardens, further carbon dioxide is released. Ditch the peat for the many equally great alternatives such as the Dalefoot compost pictured, or even better, make your own compost!
Dalefoot compost is a fantastic peat-alternative, especially their wool compost.
Re-Wild your Lawn
Let’s face it, lawns are pretty boring. Biologically they aren’t very diverse and often require artificial nutrients and weed killers to keep them looking lush and green. Converting your lawn into a wildflower meadow not only saves you the time used for mowing but benefits the bees (and other invertebrates) too!
Dandelions are an important nectar supply for early spring pollinators such as this male orange tip butterfly.
Garden for Pollinators
Our insects are suffering a catastrophic decline and we need them to survive. You can do your bit by planting nectar rich flowers covering as much of the flowering season as possible (primroses are great early supplies of nectar, whilst Ivy is a fantastic late supply!). Non-native plants can be great for nectar if they are simple open flowers, but the advantage of native plants is that they often support insects throughout their life cycle by providing food for different stages as well as a suitable habitat. You can also install log piles to offer shelter for other invertebrates such as beetles, and leave your garden untidy over winter as fallen leaves and dead stems are the perfect place for insects to hide out during the cold months.
Gardening for pollinators is more than planting nectar – the larvae of commas feast on nettles before emerging as adult butterflies.
Install a Pond
All good wildlife gardens should have a pond. Animals needs water and a pond can provide a watering hole for birds, mammals and invertebrates that visit your garden. They are also essential for breeding amphibians who will soon find your pond (don’t transfer spawn from one pond to another to prevent spreading diseases and invasive organisms). What’s more, many flying invertebrates start of life in the pond and emerge as an adult providing a food source for bats!
Monitoring when frogs spawn can tell us a lot about our changing climate. If you want to help scientists then report your spawn sightings using iRecord which you can find online or through an app for your phone.
If you’ve gardened for some time, chances are you have a stack of plastic pots somewhere. Where you can, re-use these as much as possible. But when buying new, or looking for containers for seed growing, seek out plastic-free alternatives. You can make your own pots from newspaper, re-use egg boxes and toilet roll tubes for growing on seeds and they best bit is you can plant them straight out in the tubes – which is excellent for root veg!
You can use almost anything as a pot, just be sure to drill some holes for drainage!
Insects have declined more than 75% in the last 3 decades which is just astonishing. A big part to blame for this is the continued use of pesticides. Whilst you can’t control what happens outside your garden (but buying organic veg does help!) you can control what you use at home. Organic gardening doesn’t have to be difficult. There are many natural ways to deter pests if needed, although creating lots of different habitats means you are likely to attract the predators needed to control problematic species and the garden will look after itself. Another thing to consider is only growing plants which aren’t susceptible to problems such as Lilies.
Pesticides don’t just target pests – other species such as bees can suffer too.
Garden for Birds
Feeding birds using a bird feeder though winter can help them survive when food is hard to find, but you can also make your garden bird friendly by adding plants which also provide food such as a native hedging plants; hawthorn, blackthorn, holly, guelder rose, trees such as Rowan and fruit trees and Ivy which provides food late in the season. Hedges, trees and climbers all give birds somewhere to nest and roost in, and by growing plants for insects you’ll be providing food for insectivorous birds too!
Birds love the sloes from blackthorns – if you’re lucky they’ll leave you some to make a batch of sloe gin in time for xmas.
Where do you buy your garden supplies from? Are they making positive changes to combat climate change? Do they use peat, or pesticides? Are their plants grown locally or imported (and risking bio-security issues)? By choosing where you shop you encourage businesses to do better.
Local nurseries by their nature of being smaller will have a much lower environmental impact than bigger companies, and they are usually much friendlier too. I love visiting British Wild Flower Plants in Norfolk!
Buy Local and Connect with Neighbors
Buy local where you can. Often local nurseries take more care growing the plants, and you can usually find some interesting varieties too. Buying local also reduces transportation impacts. Local selling pages are a fantastic place to offload excess plants or gardening equipment as well as picking up a few bargains yourself!
Walnut Tree Nursery in Norfolk is a great place to find some unusual varieties of more common plants.
Grow Your Own Food
If you can, try growing you own food. You don’t need a massive garden to do this as there are lots of patio varieties of different fruits and veg which can be grown on balconies too. If you don’t have much space, you could always consider an allotment. Not only does growing your own organic food reduce your environmental impact, it’s delicious too!
I’ve started using straw as a substrate in our veg patch as so far so good! This year I’m adding compost from the chickens too.
Food waste has a massive impact on the environment and not all councils collect it so some still heads straight to landfill. You can prevent this by composting your own food waste and there are lots of options to do this. You can have a basic plastic bin which works well over time, an open compost bin like the one pictured (though more suited to garden waste than food) or even a wormery! There are new hot compost bins which are ideal for small gardens as they require less space and make compost much quicker than a traditional bin. Using your own compost reduces the need to buy in compost from elsewhere too.
This bin was made from 4 pallets, the one at the front cut into sections which can be slid into the front as needed. Perfect for garden waste or areas where you don’t have rats.
Get Your Own Chickens
Animal agriculture comes with a high environmental impact. If you eat eggs, having a couple of hens is a great way to produce eggs for your family and they are much nicer than mass produced eggs too. One of the issues with current farming methods is that the rainforests are being cut down for soy plantations for animal feeds – so if you do have your own hens, make sure that the feed is soy-free!
There’s nothing quite like a fresh egg from a spoilt and happy chicken!
Garden for your Local Climate
Hose bans will become more frequent as water supplies dry up. It is predicted that some areas of the UK will suffer regular water shortages within the next 25 years so the idea of watering your garden will be a thing of the past. To avoid excessive water use, plant species which are adapted to our climate, or even more drought tolerant ones, and avoid planting in the dry seasons so there’s no need to regularly water.
Sedums require little watering and can be great for ground cover or for green roofs – as well as being a good nectar supply for pollinators.
Green Your Roofs
Green roofs can come in many forms from a small sedum roof on your wheelie-bin cupboard to a whole garden on top of a city building. They can help reduce energy costs by absorbing heat and acts as insulation for buildings as well as cleaning the air around us. When roofs are greened in cities, they help mitigate the urban heat island effect which may be more important than ever in the next few years. They also provide a habitat to our wildlife, including birds and pollinators and like this one seen at the Hampton Court Flower Show in 2015, they look stunning too!
There are no limits to green roofs, except the load bearing of the structure! To find out more head to livingroofs.org
