Choosing Seeds for Microgreens 101: Everything You Need to Know

When it comes to choosing seeds for microgreens, you’ll want to ensure you pick quality seeds. In this article, you’re going to learn everything there is to know about microgreen seeds so you can start a healthy, thriving garden.

Look for Untreated Seeds

One of the differences between growing microgreens and larger plants is that microgreens need to start from untreated seeds. Gardening seeds are usually treated with fungicides and insecticides, which isn’t harmful since the seeds start small and grow into large plants. But microgreens are 1 to 2-inch plants and treated seeds pose a higher risk, which is why it’s essential to choose seeds of microgreens that are untreated.

When ordering seeds for microgreens, make sure that it explicitly states that the seeds are untreated, and if you aren’t sure, it’s best to clarify with the company before ordering.

Order From Reliable Sources

It’s better to order from garden seed companies than sprout seed sources when it comes to finding quality microgreen seeds. Garden seed companies are more transparent about their seeds and provide a plethora of information. While you can expect a slightly higher cost, you’ll be able to find the right amount of information to guide you in your microgreen journey.

What to Look for From a Seed Packet/Catalog Page

When you purchase microgreen seeds from reliable sources, you can expect to find the right kind of information from the seed packet. If your seed packet/catalog page has the following information on it, then you’ve purchased from a reliable source:

  • CULTIVAR Name ● When you can spot the cultivar name on a packet, you can identify the specific variety of plant. A cultivar is when there are specific varieties of a single species of a cultivated plant such as broccoli where there’s Purple broccoli, broccoflower, and more. Being able to see the cultivar name will help you continuously find your favorite seeds over and over again.

  • Date of Harvest ● If your packet includes the date of harvest, you will be able to forecast your seed’s lifespan. If your packet doesn’t include this, the rule of thumb is to use the seeds within five years of purchase.

  • Germination Rate ● If your seed has a germination rate lower than 90%, then it won’t be suitable for microgreen growing. This is because the errant 10% will rot. When it comes to growing microgreens, the faulty 10% seeds can cause the other seeds to rot since they’re close to each other.

  • Organic Certification ● Make sure your packet says “organically grown” or “naturally grown” for optimal results.

  • Botanical Names ● These are the scientific names of each plant and are usually italicized and written in Latin or Greek. Knowing the botanical names of your preferred seeds will help you always identify the seeds you’re wanting to buy.
