Frequently Asked Questions (FAQ)

What is the best seed starting mix?

The best seed starting mix, also known as seeding soil, is one that’s not only nutritious for your seed or seedling but retains moisture longer than traditional top soils so it can help protect those first delicate root systems. Remember that seedlings and young plants need to be fed regularly with fertilizer and moisture. Once they have established their root systems and are growing strong, you won’t need to worry so much about increasing soil nutrients. Besides, regular garden soil will suffice for mature foliage.

Here are my picks for the best seed starting soil mixes that use coconut coir as their main ingredient.

Which seeds will grow quickly?

If you want to have an abundant garden full of life, the right mix for you is going to depend on two things. First, how much hassle you’re willing to put up with…and Second, how fast you want your plants to grow. You might be looking for something that you can just dump in a container and then forget about, forgetting about it for months. Or maybe you want faster growth and so would rather pay more for a product that comes pre-fertilized, maybe one that has even been cultivated with micro-organisms? Well here are your options.

What is the best soil for seedlings?

There are various soil mixes that can be used for starting plants. You just need to remember that you have to provide your seedlings with the right balance of air, water, and nutrition to ensure fast and healthy growth. Otherwise even a great soil mix will not make a difference and your seedlings may produce a bunch of underwhelming and straggly-looking plants.

Is seed starting mix necessary?

If you are starting your own seeds in containers, you need a seed starting mix to give your plants a healthy start. They may look like small seeds, but they are actually dormant babies with very little food and water reserves to support their initial growth. The seed starting mix I like best is a combination of organic soil and perlite, as this is the type I usually use at home. It’s a great soil to use for regular garden beds, but you need to add a fertilizer to it to get the best results when starting plants from seed.

Seed starting mixes vary in small ways like texture and design, but the overall primary ingredients are the same. Here are 5 of the best seed starting mixes:
