If you’ve never been served a salad or other dish garnished with microgreens, you may wonder if they are some strange new food. Quite the contrary. They’re the edible seedlings of many of our favourite vegetables, and they’re packed with nutrients – often more than fully mature vegetables!
They’re also easy to grow indoors and don’t require a lot of fancy lights or other equipment. You can grow microgreens in various containers under a basic shop light, providing a ready supply to add to salads, sandwiches, or any dish that needs a little garnish.
One caution: Once you start to grow microgreens, you won’t want to stop.

Step 1: Fill containers with soil
Wet the potting soil or seed starting mix. Straight out of the bag many will be dry, especially peat-based ones. Pour the soil into a clean bucket or plastic bin and add water.
Give it time to absorb the water. The soil should be moist like a wrung-out sponge.
Containers can be recycled plastic with drainage holes, or you can purchase microgreen containers, including flats with no drainage holes to hold individual inserts with drainage holes.
Fill the container with about an 20-30mm of moist soil.
Tamp down the soil to remove air pockets.
Step 2: Sow microgreen seeds
Scatter microgreen seeds across the surface of the soil. Don’t worry about spacing; smaller seeds can be fairly close together. Larger seeds, like peas, need more room.
Use seeds labelled specifically to be grown as microgreens. That way you’ll get more seeds in a packet and know those seedlings are edible.
Tamp down the seeds to ensure good contact with the soil.
Add a label to the container with the seed variety written on it.
This is especially helpful if you’re sowing several types of microgreens at the same time.
Cover the seeds lightly with soil, then gently mist with water from a spray bottle.
