Before going any further with creating your mix, we need you to note three fundamental things:

1. Your seed starting mix should be sterilised
2. It must be low in nutrients so as not to damage or kill your seedlings;
3. And its texture should be light and permeable.

A lot of seed starting recipes are sterilised in the oven for 30 minutes at 120 or 180° C. Others, on the other hand, put the potting mix in 800 watts for 10 minutes in the microwave.

Nevertheless, here are the main ingredients that should be present in your seed starting mix.

Main Ingredients

1. For high energy requirement seeds

• 40% – Peat moss or alternatives
• 30% – Compost
• 30% – Garden soil, sand and bark humus

2. For medium energy requirement seeds

• 55% – Peat moss, coco peat or wood fibre
• 20% – Compost
• 15% – Sand
• 10% – Bark humus

3. For low energy requirement seeds

• 50% – Peat moss or alternative
• 45% – Perlite or alternative
• 5% – Bark humus

Other basic seed starting mix:

1. Add 1/2 part of perlite, vermiculite or sand and 1/2 part of peat moss or coco peat;
2. Add 1/3 part coco peat or peat moss, 1/3 part compost and 1/3 part of vermiculite or perlite or sand.
