The best DIY seed starting mix has only 3 ingredients. Save money and get my no-fail recipe for organic seed starting mix you can easily make at home.
Materials – 1 part sphagnum peat moss (or coco coir) – 1 part perlite – 1 part vermiculite Tools – Clean tub or bucket
01.
Combine all the ingredients in a clean tub or bucket, and saturate the mix with water.
02.
Stir the mixture with your hands or a trowel until it's thoroughly moistened but not soggy (like a wrung-out sponge). Add as much water as the mixture will absorb.
03.
Fill your seedling pots with the homemade seed starting mix, add seeds, and sprinkle a thin layer of vermiculite over your seeds if they need darkness to germinate. (Your seed packets should give any special instructions.)
