How to Grow Kale Microgreens?
Kale microgreens are simple and quick to grow. It is not necessary to soak the seeds before planting them. Kale thrives in both soil and hydroponic environments.
Here are easy steps to grow kale microgreens:
- Fill the tray halfway with the media of your choice and evenly distribute these seeds on the soil surface.
- Then, place your trays in a dark place for a few days or cover them with another tray. Add some weight, such as a stone of around 7-10lbs.
- If you do this, your kale will grow more uniformly by seedlings being pushed into the growth media due to pressure.
- Keep this tray in the dark for three days or until you notice signs of seed germination.
- Later on, remove the weight and cover and place the seeds in the light once they have sprouted.
- Keep watering them during the growth period (sunlight stage) to nourish the roots.
- After a week, you should be able to start harvesting your Kale microgreens.
What is the Best Way to Store Kale Microgreens?
It is advisable to harvest the amount you need and use them fresh. If you need to store them, ensure they are dry before storing them. Microgreens that are wet will quickly turn to mush. Therefore, store them in a plastic bag or container to extend their shelf life.
Before harvesting, you’ll need to stop watering them for 8-12 hours. To dry, place them on a paper towel and cover them with another paper towel. To remove extra water without harming the plants, dab gently. They should last for at least a year if placed in the container.
