Can You Use Potting Soil to Start Seeds? + [What You Can Use Instead]

Naturally, a seed can grow anywhere it falls, provided the environment is suitable. Once it touches the ground, it effortlessly produces sprouts. However, if they fall on a medium that is not fertile or conducive, they might not germinate.

There are different growing mediums you can start your seeds on, but can you use potting soil to start seeds?

Yes, you can use potting soil to start seeds. However, this medium is not your best option because it does not provide an optimal environment to help your seeds germinate and survive. Potting soil is too coarse and heavy for germinating seeds.

So, if potting soil is not the best option to start seeds, what is the best alternative to potting soil?

The best medium you can use to start seeds is a seed starter mix.

Read on as we discuss the difference between seed starter mix and potting soil as well as the best seed starter mixes on the market.

Seed Starter Mix vs. Potting Soil – What is the Difference?

Seed starting mix is finer and lighter, while potting soil is coarser and heavier.

The finer texture of starter seed mix creates a soft environment for the plants to grow, especially the roots, unlike potting soil, which has a coarse texture.

It is made not to weigh down your seedlings as they thrive.

Potting soil is heavier because it consists of more materials, including fertilizers and maybe some sand (not always). Soilless potting soil is also called potting mix.

Seeding starter mix does not contain added nutrients, so it cannot sustain the seedlings beyond a certain stage. Potting soil on the other hand contains added nutrients.

The texture of potting soil, coupled with the added nutrients makes potting soil the best choice for growing potted plants as well as plants that have been transplanted and grown into containers.

Seed starters on the other hand are specifically made for seed germination into seedlings, which doesn’t require large amounts of nutrients.

Is Seed Starter Mix Necessary?

A seed starter mix may not be a must, but it is necessary because it creates an excellent environment for your seeds to start well at the sensitive stage and germinate successfully.

The main benefit of seed starters comes during cold climates because that’s when your seeds are at the risk of damping, which is disastrous and can ruin your gardening season.

Therefore, even though a seed starter mix is not a must, you should consider it because it provides the right environment for your seeds to germinate and thrive.
