Making your own seed starting mix is a great way to ensure that your seeds get the right balance of nutrients and moisture. Here’s how to make a basic homemade seed starting mix:
Ingredients
1 part vermiculite
1 part perlite
1 part peat moss or coconut coir
(Optional) 1/2 to 1 cup of organic fertilizer per 3-4 gallons of mix
Instructions
In a large container, mix equal parts vermiculite, perlite, and peat moss or coconut coir. Use a large container that will hold enough mix for your seed-starting project. Mix the three ingredients thoroughly to distribute them evenly. If desired, add a small amount of organic fertilizer to the mix. Use 1/2 to 1 cup of organic fertilizer per 3-4 gallons of mix. Mix the fertilizer in thoroughly with the other ingredients.
Once you have mixed all the ingredients together, your seed starting mix is ready to use. Fill your seed-starting trays or pots with the mix and plant your seeds according to the instructions on the seed packet.
It’s important to keep your seed-starting mix moist but not waterlogged, as too much water can lead to damping off and other problems with seedlings. You can also add a layer of sterile potting soil on top of your seed starting mix to help prevent fungal growth and provide additional nutrients to your seedlings.
