In a previous post, I explained the basic differences between coconut coir and peat moss based potting soils. Now I am going to show you how to make your own potting soil using a peat moss base.
Here’s what you need to make your own organic potting soil:
Sphagnum peat moss – holds water and air; provides little nutriton
Vermiculite – provides minerals (potassium, calcium and magnesium)
Garden lime – provides minerals (calcium) and balances acidity of peat moss
Compost – provides the lion share of the nutrition to the plants
Large bin to mix it all in. Watch the video and you’ll know why you’ll need to use a large bin.
To mix it:
Add the mixture at a close 1:1:1 ratio of the peat moss: vermiculite: garden lime. You definitely want peat moss to be the dominant ingredient. Mix well.
Now that you have the peat moss mixture, add an equal part of compost. Mix well.
Add some water to dampen the mixture. Don’t want to saturate it. Mix well.
