Growing Basil Microgreens: How to Grow Them At Home

Growing basil microgreens is a fun and rewarding project to do at home. They’re easy to grow and make a lovely, delicious addition to meals. Here’s everything you need to know to learn about growing basil microgreens.

Growing Basil Microgreens: Getting Started

Basil microgreens are quite an easy type of microgreen to learn to grow. They’re easy to germinate and sprout and tend to readily produce nice tasty green leaves with adequate light. All in all they’re a nice way to get comfortable growing microgreens while growing a familiar herb that you already may know how to use in your cooking.

First, collect the supplies for growing basil microgreens (or purchase a little indoor basil gardening kit). You’ll need a container, potting mix, and basil seeds, as well as clean water and sunlight. Let’s look at the supplies required to grow basil microgreens.

Supplies for Growing Basil Microgreens

• Basil Seeds: your favourite variety
• Container: Tray, preferably with drain holes
• Potting Soil: Well-draining organic potting soil
• Water: Filtered or non-chlorinated, if possible
• Sunlight: Sunny window and perhaps an LED

Basil Seeds for Growing Microgreens

Buy basil seeds or grow your own from fully-grown basil plants. Basil seeds sold specifically for microgreens (where you need lots of seeds) are usually in packages over 1 oz, and generally contain more than 1000 seeds. You can also grow microgreens from clean basil seed for the garden. Here are some basil microgreen seeds to try:

• Ciao Bella Organic Basil Blend Microgreens Seeds
• Italian Genovese Basil Seeds (Organic, Heirloom) – large size packet
• Certified Organic Basil Seeds – Choose Variety (small packets only)
• Heirloom Thai Basil Seeds (Large Pack)
• Sweet Basil Microgreens Seeds

Containers and Trays for Your Basil Microgreen Garden

Basil microgreens can be grow in a baking tin, old takeout tray, or a specialized microgreens tray. Check that the tray/container you’ve selected has drain holes to allow excess water to escape. It’s also nice to have a second tray (without holes) under the growing tray, just to catch and hold the water after it drains so it doesn’t end up all over the countertop.

• Plain Black Plastic 10″x10″ Microgreen Tray Pack
• Extra Strength Plastic Colorful 5″x5″ Microgreen Trays
• Hamama Microgreens Starter Kit with Ceramic Growing Tray
• FatPlants Cedar Microgreens/Wheatgrass Planter with Kit

Basil plants will “drown” if their roots become waterlogged. Plants require air in the soil as well as water. If you do grow them in a baking tin or something without drainage, take great care not to overwater them (and watch for signs of excess moisture).

Saturating the soil for an extended period will suffocate the plants. There is not much room for air in the soil if it is saturated with water. The only time basil seeds will put up with a little extra water is during the initial germination phase of growing basil from seed. Once roots are established, let them dry out a bit between waterings.

Potting Soil for Growing Basil Microgreens

For your potting soil, choose a well-draining variety. Some high-quality potting soils are specially formulated for growing plants from seeds. These “seed-starting mixes” are perfect for growing basil from seed, as are high-quality all-purpose potting mixes.

• Burpee Natural Organic Premium Growing Mix
• Dr. Earth Pot of Gold Organic All Purpose Potting Soil

Kits for Growing Basil Microgreens at Home

There are also handy-dandy kits for growing small amounts of basil microgreens at home. You can harvest the basil plants when they’re small, as microgreens, and also leave a couple shoots to grow into bigger plants if you like.

How to Grow Basil Microgreens from Seeds into Sprouts

1. Fill the tray container with the potting soil.
2. Moisten the potting soil so it is damp, but not wet (muddy). After moistening, the soil should reach approximately 1″ from the top of the container.
3. Place basil seeds on the soil about 10 cm (4″) apart. I used to try to soak my basil seeds before planting (like other microgreens), but they are too small!
4. Lightly sprinkle 1 cm (less than 1/2″) of soil on top of the tiny basil seeds.
5. Gently water the soil until top layer of soil is saturated.
6. Place the container in a warm sunny area or under a plant light. Light helps the basil sprouts grow :)
7. Keep the soil moist and warm while the seeds germinate and sprout into basil seedlings. You’ll have germination problems if the environment is too dry to support growing basil from seed.
8. Wait! Basil takes a long time to germinate in comparison to other seeds. Grow some peas or another quick microgreen crop alongside your basil if you’re looking for a quick win.
9. Water the sprouted seedlings regularly.
10. Once the basil sprouts have become established, watering can be reduced. At this point, wait until the soil becomes dry before watering the plants again.
11. Basil can be harvested as a microgreen once the sprouts have grown several inches high. Yum! Basil microgreens make a lovely garnish on pasta or a perfect addition to a tomato salad.
12. If you have too many basil seedlings, save a few to allow to grow into large plants!

Considerations for Growing Microgreens in an Indoor Environment

Can you grow basil microgreens indoors? Yes! you can certainly grow basil microgreens indoors with a few tricks that mimic nature. Growing basil microgreens indoors rather than outdoors does require some special considerations to make sure your basil sprouts are healthy. Read on to learn about growing the healthiest greens.

Light is Key for Growing Basil Microgreens Indoors

The most important consideration is providing enough light. If you have a bright sunny window, place your basil greens tray where it will get lots of light throughout the day.  Keep in mind that basil plants love 12 hours of light each day, and need at least 4-6 hours of direct sunlight to thrive, so ensure you’re selecting your window carefully.

If you’re at all doubting that your basil is getting enough light, get yourself a plant light. You can either buy a fancy plant light set-up, or just a regular fluorescent light. Lately some indoor gardeners have been moving towards inexpensive and compact LED plant lights. Place the basil plant right under the light so it can soak up all the rays.

Growing Basil Microgreens Indoors? Yes! – With The Right Climate

You may also want to consider other environmental factors such as heat and humidity. If your micro green tray is very close to a drafty window, it could be negatively affected by the cold.

Basil also may be affected by indoor humidity. The dry winter air in heated homes can desiccate the soil and dry out the plant. Consider using a humidifier if the air in your house is particularly dry.

Air Movement for Indoor-Grown Basil Microgreens

Lastly, basil sprouts benefit from some sort of air movement. If your house doesn’t have an active air movement system, a fan may help to simulate the outdoor environment. Air movement will help your basil sprouts grow strong and also discourage pests and disease.
