Capture Carbon In Your Garden

Can your garden help reverse the effects of climate change?

It most certainly can!

Your garden can be an effective carbon sink, by using your plants and your soil to capture and store CO2.

This Chelsea Fringe 2017 project, run by fringe regulars Modern Mint, will show you the simple yet positive actions you can take to make your garden a carbon capturing eco-system.

Share With Us How You Capture Carbon In Your Garden

Please share this project with all of your gardening friends, or show us how you already capture carbon in your garden by using the #capturecarbon hashtag on social media.

We will be retweeting, liking and sharing your photos and comments throughout the Chelsea Fringe festival so that all can see how our gardens can make a positive change in the world.


You can share your carbon capturing techniques with Modern Mint in these following places:

But how exactly can you do it?

How To Capture Carbon In Your Garden

1. Plant A Tree (Or Several!)

Trees pull carbon from the atmosphere, holding it in their woody stems. It is the simplest and easiest way of capturing carbon in your garden, while also providing habitats for birds and possibly a crop for you too, if you choose the right tree.

Any prunings you make when the tree gets too big can then be used to create a wildlife habitat. This is the best way to dispose of them, as burning the prunings will just release the CO2 back into the atmosphere.

2. Improve your soil

The biggest store of carbon in the world is our oceans. The second biggest? Our soils.

Capturing CO2 in your garden soil is easier than you can imagine. The first thing to do is stop digging. (That has got to be good for your back too!)

By digging your soil it is exposed to air, which in turn releases CO2 and nitrous oxide. So if you have a vegetable plot, save yourself the effort of double digging, or even turning over the soil at the end of the harvest (yes, the frost will help to break up the ‘clods’, ready for planting again next year… but the only reason you have ‘clods’ in the first place is because you created them by your digging!)

Instead of digging you can improve your soil by adding compost or other organic matter. Copy nature by placing a mulch of your own garden compost onto the soil, then let the worms do the work for you. This creates humus and builds top soil, which in the long run is better for your plants.

For more information about the benefits of no-dig vegetable gardening and the use of compost, see anything by the specialist vegetable gardener Charles Dowding.

3. Cover Your Soil With Plants

If you can’t mulch with compost to help build your soils capabilities to sequester carbon, you can at least grow something instead.

By reducing and keeping bare soil to a minimum in your garden, you get the benefit of more flowers too.

4. Don’t Use Artificial Fertiliser

Now this is an interesting one! Did you know 1 kilogram of carbon is burned just to make 1 kilo of nitrogen fertiliser.

(Even worse than that, 5 kilos of carbon are burnt to make 1 kilo of pesticide…. you can do an awful lot to lower your carbon footprint by just refraining from chemical pesticides…)

By using compost on your flowerbeds, instead of using fertiliser, you still help give your plants all that they need to grow well  because it creates a soil rich in beneficial fungi, mycorrhizzas, water holding capabilities and air pockets.

Forgetting for a moment that feeding the soil is better for your plants than feeding the plants, and putting aside the vast sums of energy needed to make artificial fertiliser, why else should we stop using it in order to store carbon in our garden?

A big influx of artificial fertiliser to the soil your plants are growing in will stop the plant exchanging the carbon it has taken from the air with the nitrogen and other nutrients it needs that are available in the soil.

No exchange means the process plants rely on to grow well breaks down, your soil stops improving, you start to panic because nothing looks healthy and so resort to more and more fertiliser to improve the situation.

This downward spiral can be stopped by improving the humus content, the organic matter, in your soil – not by feeding the plant alone.

5. Use Peat Free Composts

Peat free composts have, historically, been considered a bit rubbish in the garden media.

All that has now changed!

Peat free composts can be bought from places like Dalefoot, who make their mixture from wool and bracken, or Sylvagrow.

They are recommended by Earth Friendly Gardeners across the country and the results are sublime, with many nurseries now growing all their plants in peat free compost.

By not buying or using peat-based compost, you reduce the destruction of peat bogs, a habitat that holds vast stores of carbon. These are non-replaceable stores of carbon too, because a peat bog only grows at a rate of 1mm per year.

Making your garden a place for peat free compost is a fine way to keep fossil carbon stores locked up.

These 5 simple actions can turn your garden into a carbon sink – so start today, and let us know about it!

How To Reduce Your Garden’s Carbon Footprint

A few ideas we like are:

  • No petrol and oil powered tools like mowers, hedge trimmers, leaf blowers and strimmers. But it does mean you need to use sharp tools to replace them, or your life will be tough….
  • Grow from seed at home, so it saves the transport cost of plants and the waste of non-recyclable plastic plant pots.
  • Grow as much food as you can – herbs, fruit, vegetables and flowers for the vase will also taste and smell better when freshly picked!
  • Reduce your lawn and replace it with flowers. Mulch grass clippings onto any lawn you do have.
  • Don’t heat your greenhouses.

Ivo Graham

Ivo Graham is a comedian. We met him, and some of his family, last year at a Christmas Fair. He bought a gift for his father (a log gobbler, which he thought his dad would find funny….) and in the process of buying it also supported the charity the Christmas Fair was raising money for. He was a lovely chap and laughed a lot. We like that in our customers….! Then lo and behold, here he is, providing 30 minutes of funny on the BBC – check it out: Ivo Graham – Live from the BBC He will also be …



Roses – Another One For People Who Plant For Bees

We are currently writing a book about plants that do a great job of Helping The Honeybee. This means we are always on the lookout for flowers that are attractive to our little, honey making friends. This week we have heard plenty of buzzing coming from: Dead nettle Helenium Alliums Veronicastrum Escallonia Plus we glanced in a magazine and saw a note about bees preferring dark flowers when they forage in the shade. We will research this a little more for you, but worth making a note of and thinking about right now if you have a dark patch of …



Visit To David Austin Roses

Last week Modern Mint took a little time out to visit David Austin Roses. The English roses they have created were still blooming beautifully, though the staff there insisted that, because of the warm weather this spring, we had missed the VERY BEST of the flowers. We don’t think so…. A post shared by ModernMint (@modernmintshop) on Jun 27, 2017 at 6:11am PDT This photo is actually of the trial fields, the roses here are part of the breeding program and are being tested as potential new introductions. So look as close as you like, but you won’t be able …
