Making Your Own Organic Potting Mix

As it was a beautiful sunny day in Sydney, I decided to spend the day in the garden, re potting some pot plants.  Lately I have been making my own organic potting mix, which I learnt how to do from a free City of Sydney Council, Live Green Workshop.

My Aloe Vera plant's new home. Finished results.

To make good potting soil, you  need to include three elements; water, air and nutrients.  Here are my ingredients for making organic potting mix that has all three of these elements:

1) Water – Coconut fibre

2) Air – Sand

3) Nutrients  – Humus  (can be compost or castings from a worm farm or even EM Bokashi treated dog poo.  NOTE if using dog poo in the recipe, it is well advised not to use the potting mix for edible plants, like fruit, veggies and herbs).

Let me explain in more detail:

Purchase organic compressed coconut bricks from nurseries or hardware. Make sure they are organic!

Organic, compressed, coconut fibre

Soak the coconut bricks in water for at least 15 minutes, so the compressed brick will separate and expand.

Place organic, compressed coconut fibre into a bucket of water

If like me you do not have a wheelbarrow (for mixing the potting soil), lay a tarpaulin on the ground.  Add the bucket of separated and wet coconut fibre onto the tarp.

Use a tarp to mix your organic potting mix, if you do not own a wheelbarrow

Now add the sand (in the same quantity as the coconut fibre).

Sand is an important ingredient in creating your own organic potting mix as it provides air

Now add the nutrients.  As I am not re planting edible plants like fruit, veggies or herbs today, I will use my EM Bokashi treated dog poo.  Again in the same quantity as the sand and coconut fibre (all three parts equal in quantity).

Dog poo treated / coated with EM Bokashi powder makes good nutrients in organic potting mixture for non edible plants

Mix well together.

Mix the coconut fibre, sand and dog poo coated with EM bokashi powder together on a tarp

Now to pot your plant (just as normal).  Using one of my  garden pot ‘finds’ – I picked this garden pot up just recently from the side of the road.  Saved it from going to land fill.

As you can see this Aloe Vera plant is overgrown and needing a bigger garden pot.

And Walla……..the finished results.

Here is my mint that I replanted a month ago.  As mint is an edible plant, I used worm castings as the nutrients in my organic potting mixture.  The mint has doubled in sized since I planted it!

Mint re planted one month ago has now doubled in size.

Bokashi Bin Working Together With Our Worm Farm

I have been working on this video for awhile now.  Any free moment I would do a little bit more to finish it (I have been really busy at work).

This is a very basic and simple illustraion on how we use our Bokashi bin, together with our worm farm to recycle our kicthen organic waste.

The only improvement I could suggest to our system is that we should have two Bokashi bins.  When one is full, we let it sit until the next one is full.  This will give the first bin a longer time to brake down the waste (ie giving the EM powder more time to work).  Then we would simply rotate the bins around.

EM Bokashi update & dog poo

On the 12th of July 2008 I wrote a post titled ‘What to do with dog poo?’.

This post was about how we were going to recycle our dog poo (and with two dogs, believe me when I say we have a dog poo factory at our house).

Now moving ahead to the 19th of October 2008,  I  bought some new plants back home from the nursery.  These plants were replanted in larger pots with potting mix and the dog poo that had EM Bokashi sprinkled on it (again read the post ‘What to do with dog poo’ for more info).

 

Here are photographs I took on that day:

Today over four months along, I took another photograph of that same plant:

Wow our garden pot plants love the dog poo.  As the soil level of pot plants need to be replenished, we top up with a mixture of potting mix and dog poo (sprikled with EM Bokashi powder).
