A lot of young seedlings plants of edible leafy greens.
Microgreens are young seedlings of many edible leafy greens, herbs, and flowers. They are grown to be eaten within seven to 21 days of germinating. These miniature versions of vegies and herbs are packed with flavour and are said to have more health benefits than their mature counterparts. They’re perfect for salads, sandwiches, juicing, stir-fries, and garnishes.

What you need to know about microgreens

Name: microgreens, micro herbs, vegetable confetti.

Height: 5-7cm.

Plant type: seedlings of leafy vegetables, herbs, and some flowers.

Climate: all zones.

Soil: seed-raising mix.

Position: full sun.

Flowers: N/A

Foliage: varies depending on the seed type. 

Feeding: not required.

Watering: water regularly to keep the soil moist. 

Appearance and characteristics of microgreens

Microgreens are the young seedlings of many edible leafy vegetables, herbs, and some flowers. They are only grown from seed and are harvested once the seedling produces its first true leaves (the second set of leaves after germination). If allowed to continue growing, these seedlings grow into their mature counterparts.

Research has shown that these immature versions of edible plants have significantly more nutritional benefits than their mature forms. The flavour is more robust, too.

Microgreens have a short life. Once they are harvested, the seed-sowing process needs to be repeated for successive picking. It’s a good idea to sow a new batch once every couple of weeks to ensure a continuous supply. Popular microgreens include amaranth, basil, beetroot, kale, lettuce, mustard, peas, rocket, sorrel, sunflower, and watercress.

Uses for microgreens

Microgreens are so versatile. Harvest them to use in sandwiches, salads, smoothies, or any dish that calls for greens. They make a great garnish, too. Try a combination of different microgreens for a complex flavour hit. 

How to grow microgreens

Microgreens can only be grown from seed. As they don’t have a long lifespan, they don’t need much room to grow, so any shallow container is perfect – seedling trays, egg cartons or recycled plastic fruit punnets are ideal. Fill containers with seed-raising mix, scatter seeds over the top, and lightly cover. Mist thoroughly to moisten the soil and position in a warm, brightly lit spot, such as a windowsill. Water regularly to keep the seeds and mix moist.

You can also use a purpose-built microgreen growing tray, which doesn’t require seed-raising mix – simply add water. Another alternative is to grow microgreens on unbleached paper towels, but avoid cabbage and carrot seeds as paper towels don’t provide sufficient support for their roots.

Once harvest is over, repeat the seed-sowing process to ensure an ongoing supply of microgreens. If growing microgreens in seed-raising mix, you will need to use fresh mix as existing roots can restrict new growth.

Caring for microgreens

Microgreens need very little care except regular water to ensure they never dry out. Mist thoroughly or use a narrow-spouted watering can to gently water.

How often should you water and feed microgreens?

Water regularly to keep the seeds moist. There’s no need to feed microgreens.

How and when to harvest microgreens

Snip plants at the base of the stem once the first set of true leaves has formed (the second set of leaves after germination). This is usually within seven to 21 days of sowing seeds.

Diseases and pests that affect microgreens

Due to their short life span, microgreens are not affected by any pests or diseases.

How to propagate microgreens

Microgreens can only be propagated via seed. The seed-sowing process is repeated once harvest is done. Sow successive crops every few weeks to ensure a continual supply.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
