Making Soil Blocks
Preparing the Mix
As a guide, 5 litres of mix makes 30 soil blocks when using the Ladbrooke Mini 4 soil blocker.
Mix dry ingredients together. Note: If you are mixing for the first time, set aside ~ 1/3 of the total mix. You will be able to add this back later if your accidentally add too much water and your mix becomes too wet.
In a container with a flat bottom (e.g. old baking tray or large tub), add 1 part water to 2 parts dry mix and mix well.
You are after a consistency of sticky mud or porridge. Add more water until the right consistency is obtained.
To check that your mix is of a good consistency for blocking simply squeeze a handful.
Making The Soil Blocks
Push the Soil Blocker down into the mix. This is known as 'charging' the blocker. A useful way to tell if you have enough mix in the blocker is to look for water seeping at the top of the tool. You may need to charge several times. We find that having the mix 7-8 cm deep results in efficient charging, such that we only need to charge once.
Twist the tool slightly (to remove any suction) and lift.
Scrape any excess mix from the bottom of the blocker.
Eject the soil blocks into your desired tray.
