What is Seed Starting Mix?

Seed starting mix is a growing medium that is specially designed to help seeds germinate. It’s a soilless mix of natural ingredients like coconut coir, perlite, vermiculite, sphagnum peat moss, pumice, rice hulls, and others.

There may be organic material like worm castings added as a fertilizer, but you typically won’t find chemical fertilizers in the best vegetable seed starting mixes.

Is Seed Starting Mix the Same as Potting Mix?

No, seed starting mix and potting mix are two different things.

Seed starting mix is designed to help seeds sprout but it isn’t designed to feed plants long term. Potting mix, on the other hand doesn’t provide an ideal environment for seeds to sprout but it is designed to feed plants for weeks or months at a time.

Seed starting mix has nutrients to help seedlings germinate, encourage root development, and provide basic nutrition for very young seedlings.

A seed has all the nutrients it needs to germinate contained within the seed itself so it doesn’t need a lot of fertilizer. Too much fertilizer is actually detrimental to delicate seedlings, which is one of the reasons why a good seed starting mix for vegetables is a better choice for starting seeds.

Plants started in a seed mix need to be moved into a different growing medium once they’ve developed their first set of true leaves. Larger plants benefit from the additional organic matter and added fertilizer in potting mixes and garden soil.

Potting Mix

Similar to seed starting mixes, potting mix is often made with sphagnum peat moss, vermiculite, perlite, or other similar ingredients. These ingredients improve water retention and create an environment that helps plants thrive in containers.

Potting soil also contains additional ingredients not found in soilless seed starting mixes like actual soil, bulky compost, manure, or chemical fertilizer.

The texture of potting mix is thick and dense. It’s a lot heavier than seed starting mix. It often has large chunks of bark or small sticks. Since it has more organic matter and fertilizer, potting mix is suitable for growing plants in containers for several weeks or months at a time.

Why Use Seed Starting Mix?

Since it’s specially designed to help seeds sprout, seed starting mix is the ideal growing medium for starting seeds indoors.

Good seed starting mixes for vegetables are loose, fluffy, and fine. The lightweight texture makes it easy for seeds to sprout and grow up out of the mix. There aren’t big chunks of mulch or sticks in the way to block their growth like you often find in potting soil.

Roots are also free to grow and stretch down through a good vegetable seed starting mix. Because the mix is loose and light, oxygen can easily reach the roots, helping them grow and develop.

The best seed starting mixes for vegetables have excellent moisture retention. Seeds need to stay moist while they’re germinating and seed starting mix helps you do that.

You can use a potting mix to start seeds but you’ll have better and more consistent results with a high-quality seed starting mix.
