How to Grow Microgreens
Ask This Old House landscape designer Jenn Nawada learns how to grow and harvest microgreens.
- Some seeds require you to pre-soak a handful of seeds to promote early germination (follow directions on the seed packet). If you’re worried about bacteria spreading from one seed to the rest, you can add a little hydrogen peroxide to the water.
- After the presoaking is complete, rinse and drain the seeds in a colander.
- Pour organic soil into plastic container and fill it up half way.
- Push soil down evenly with the bottom of a second plastic container.
- Water the soil thoroughly.
- Spread the seed densely over the top of the soil.
- Use a spray bottle (rather than your fingers) to help spread the seeds evenly.
- Cover the seed with a plastic container and place it in a warm space away from sunlight to germinate.
- In 3-4 days once the seeds have sprouted, remove the cover and bring them to a sunny area.
- By 7-10 days, the microgreens should be ready to harvest.
- Sterilize a pair of scissors with hydrogen peroxide and cut the microgreen close to the soil, but do not pull up any soil in the process.
- Compost the excess soil and recycle or reuse the plastic container.
- Microgreens can be stored for up to a week in the refrigerator.
