What kind of soil do you recommend? Im limited to what's available in my local area
I start with:
Step 1 : cotton wool seed germination
Step 2 : then into polystyrene coffee cups
Step 3 : then into 4.5 litre / 1 gallon black planter bags
Step 4 : then into final pots - I am using 25 litre / 6 gallon pots
So for soil ... another hard lesson from personal experience ...
Step 2
- make damn sure the soil is sterile
- I buy nursery potting soil
Step 3
- make damn sure the soil is sterile
- I buy nursery potting soil and mix 50/50 with nursery compost
I used a handful of garden soil ... and I found out later that I had picked up cutworm eggs. Those hatch and live inside the soil, and truly phuq with everything. They eat live plant roots. They cut around a plant stem and kill it.
I only found out when I gave up on the last 5 of my seedlings because they refused to grow. Those 5 were little runts that demanded attention and went nowhere compared to the rest. When I emptied out the black planter bags, I found between 1 and 5 cutworms in each. Some as big as the top 2 joints of my little finger.
Nursery potting soil and Nursery compost are both sterilised during production.
High heat.
Kills all bugs.
Kills all eggs.
Kills all weeds.
Kills all seeds.
Step 4
You can scrounge up some natural soil, at less risk than the smaller plant stage.
Not zero risk ... but significantly less..
Try to get some soil that is healthy 'forest soil' ... or in other words ... diverse in nature.
Somewhere that there is rotting vegetation and leaves. A bonus is to look for places with mushrooms or mycelium.
Darker soil is usually the most nutrient rich.
If you are "gathering soil from the wild" then scoop up the top foot into a separate container
- this is the topsoil ... keep it aside
Then scoop up the deeper soil into its own container
When you prepare your pots or your garden bed ... opposite order
Deeper soil in first to the bottom
Top soil back on top
The reason for this is the topsoil has a different microbial life profile to the deeper soil. A lot of good stuff happens on the soil surface layers. Don't kill that off.
For
Step 4 amend the soil with your own compost, or buy compost.
Start a worm bin if you can.
Worms will compost stuff in 6 weeks compared to 6 months on a compost heap
Worms are also cold composters
- a compost heap typically goes to 135° F or 70° C due to thermophilic bacterial activity
- worms do not raise the temperature much
- worms do not break down the compost material all they way down into 'raw elements'
... they leave a lot of nutrition behind in the form of higher order compounds

Edit addition
Some people recommend pushing any natural gathered soil through a screen.
To screen out pests and pest eggs.
To screen out seeds.
A builders screen works well ... the one they throw sand through when mixing cement to screen out debris crap.
