Raising beds - concrete tiles and reo put to use

Principle 6: Produce no waste

In an effort to get more engaged with my local community I began writing a regular article for  the Telegraph, our local newspaper. My plan is to write an article every couple of weeks about projects that I'm involved in or inspired by - I've decided to call the column: Do It Yourselfer. These articles are being reproduced on the Permaculture Principles blog.

On this blog post I thought that I'd reproduce the first article that I wrote with some more detail and links to expand on what I've been up to. If you've got any thoughts about this idea or the projects, please leave a comment - and feel free to share these posts if you find them of interest. - Cheers, Richard Telford.

The first of the Do It Yourselfer articles published in the Telegraph. Note: I didn't write the heading - which is not what I'm trying to say. Reproduced below with added pictures and captions.

Do It Yourselfer #1

I like to get my hands dirty and have a go a just about anything. It’s something that runs through my veins. When asked “what’s your profession?” in those probing forms that you have to fill out, I started answering “Do it Yourselfer”. Seems to be the best fit for a generalist like me.
So, what’s this article about? I had this idea for writing a regular piece about things to do around the home that could inspire people to have a go themselves. There’s somethings that work, and there’s others that don’t. There’s lots of ideas and knowledge ‘out there’, so I thought it would be good to share some of what I’ve learn't and been inspired by.

Raising beds

When I deconstructed the dilapidated house on the site that was later to become Abdallah House I was confronted with one material that I was really challenged to find a productive use for. Old concrete roof tiles.
There’s a lot of these in the area. As I understand it, once the protective coating wears away, they start to soak up moisture when it rains that can double the weight of a roof. This can cause the roof to sag, crack and leak.
So, what to do with 750 tiles? I ended up using most of them to build raised garden beds - there’s nothing new about that, or is there?
Initially I thought that garden beds should be low rather than high, so that the water doesn’t drain out of the soil. But, when heavy rains come, the beds can flood and the plants die (I learnt that one).
Heavy rain caused flooding of garden beds in the backyard

I dug the tiles in to about half their length and held them in place with soil. String lines were used to ensure that the beds were straight and level. The capping tiles came in handy for corners.
Footpaths around the beds have been dug in lower, providing the soil to raise the beds and acting as basins to capture and store rainwater.
A thick layer of mulch was added onto the paths, which help to maintain moisture, reduce weeds and provides a good walking surface. The mulch eventually breaks down into a rich compost that can be dug back into the beds, building them up further over time.

Thick course mulch used to fill in the recessed paths, as Peter Lockyer talks about the house design at SHD14.

What I found was the moisture from the soil wicks up into the garden, and the raised bed encourages the plants to send their roots down to access water as required. The beds do dry out in the summer, which they would anyway, but you can take advantage of those freak rain events by capturing the water that usually drains off the hard dry surface.

The path around garden bed at the front of our house has been designed to catch and store water, which seeps into the soil to be later accessed by the plants.

In a tweak on the idea, I used a light reinforcing mesh, of the 200 x 200mm variety, to create a curve that backs against the brickwork of our recently completed greenhouse. The 6 metre by 500mm wide off-cut was hammered in 200mm into the surface leaving the top one and a half rows, about 300mm above ground.
The tiles were dug in about 50mm at the base and a large amount of soil was added to raise the beds about 400mm from ground level. The pressure from the soil locks the tiles into a gently sweeping curve.
This garden bed will be used to grow corn with beans to climb up the stalks, providing some shade for the greenhouse in time for summer.

Using reo as a form, tiles are set into the soil about 50mm and soil filled in to hold the tiles in place.

Why produce the 2015 Permaculture Calendar?

Principle 3: Obtain a yield

I've been working towards making a living from doing what I love. This has been a long process which has been helped by the fact that we live a simple lifestyle. Reducing our overheads so that our family of four only requires around AU$10,000 a year to cover our normal living expenses.

For the first time I have generated enough income through the ongoing development of the Permaculture Principles website to cover our living costs - the majority of that has come from the sale of the Permaculture Prinicples Calendar - which is now being distributed from partners in the UK, USA and NZ as well as from here in Australia at Abdallah House.

The sale of other permaculture publications, many of which I've been involved in producing, also contributes to the running of the website. Since July 2013 I've committed to putting a portion of this income aside, along with that of the calendar, to support the wider permaculture community.

Permafund

It was important for me to ensure that I embodied the values that I highlight in the website and calendar. I've applied the ethic of Fair Share, in part, by donating (or tithing) 10% all profits that I generate from the Permaculture Principles business to Permafund. This financial year past my contribution was $1013.77 - The donations given to the Permafund are used to promote Permaculture projects to assist with resilience in the developing world, in places of extreme need and in projects promoting permaculture.

The 2015 Permaculture Calendar

Since taking over the co-ordination of the calendar in 2012 the 2013 and 2014 editions have sold out. I have high hopes that the calendar will continue to be supported in the same way and have increased the print run slightly to 3,000. It's not a lot in the big scheme of things, but challenging enough to produce, market and sell. I feel that this project is worthwhile on many different levels.

The main purpose of the calendar is to help people learn the design principles. It does this through the familiarisation with the principles using the name, icon, an image and short story - one featured each month. Enough time to absorb some of what each one is about and how it might be applied.

Each of the photo descriptions brings to light and important project or observations that could easily get swept away during our high paced lifestyles. They illustrate how the featured principle has been applied, that may inspire the reader to think about applying them in their own project or lifestyle.

The principles are the building blocks of permaculture. To this is added a basic moon planting guide which I've found valuable in motivating me to plant certain types of seeds and get active in the garden. Our family uses the calendar every day to plan ahead and see what's coming up.

If the calendar sounds like something that you'd like to check out then visit the website.
