When to Harvest Microgreen
Your Microgreen has been growing for two weeks. Their height has reached 7~8cm.
Yes, this is a good time for you to enjoy Microgreen harvest!
But hold on, different variety of Microgreen has different growth rate. Although most Microgreen are ready for harvest within two weeks, there are exception. For example, Red Amaranth or Swiss Chard usually require two weeks from seed sow to germination, so their harvest will surely be later.
Microgreen of Kale KA01 has beautiful purple vein and pungent spiciness. You may harvest them during this stage, or wait for the first set of true leaf to harvest
Apart from time and height, you want to know the variety well to make a decision on when to harvest. Here are some clues:
- Harvest during its cotelydon stage：Radish, Swiss Chard
- Harvest when the first set of true leaf just emerge：Cress, Broccoli, Kale, Amaranth, Sunflower
- Harvest after the first set of true leaf is grown fully: Herbs such as Lemon Basil, Sweet Basil, Coriander, or Dill. Some leafy greens, particularly Fringed Mustard, Sorrel, or Pea
All Microgreen varieties can be harvested at cotelydon stage, but some varieties are more flavourful after their first set of true leaf emerged.
Coriander (or Cilantro) will be more flavourful if harvested after the first set of true leaf is fully grown
How to Harvest and How to Eat Microgreen
Consider harvesting Microgreen with a pair of scissors or knife. Harvest the delicate greens 1.5~2cm on top of soil. You may harvest them all at once, or cut the amount according to your need in a few days, but not too many days or the texture and flavour may decrease.
We want to consume the cotelydon and first set of true leaf of Microgreen, therefore Microgreen usually provides only one-time harvest. Having said that, some Microgreen varieties are suitable for growing into mature vegetables. Some growers may save the strongest Microgreen as seedlings and transplant to continue the growth.
To maximise the absorption of nutrients from Microgreen, it is best to eat them raw. However, you may also steam, or cook them in water that is 60~80℃, which can still retain eighty percent of their nutrients.
Most Microgreens are very tangy, especially Brassica Microgreen such as Rocket, Kale, or Radish. By adding nuts and oil, the tanginess can be balanced out, so eating Microgreens with sesame oil or dressing is a good choice!
Sunflower Microgreen is sweeter than other Microgreens, with a nutty flavour. They can also balance out the tanginess of Microgreen Radish when eaten together. Add sesame oil or dressing and Bon Appetite!
What to Do with Growing Medium After Harvest
The roots of Microgreens will cover the whole growing medium
In the first episode of this series, we talked about materials that are suitable for growing Microgreen. No matter if you are using soil potting mix, coco coir, or hemp, you will find that the growing medium is covered by Microgreen's root structure.
Growing medium cannot be reuse immediately, but you can integrate them as part of your compost. That's why if you are already growing a garden, you can grow Microgreen in the most eco-friendly way!
