Description

Watercress has been around for a long time, and it was first commercially cultivated in 1808 in the UK. Today it’s grown in many parts of the world and used as a culinary addition with its delicious and peppery flavor.

In supermarkets, watercress is typically being sold in sealed plastic bags with added moisture. As they thrive in water, they are unsuitable for distribution in dried form. So they will not hold for long after harvest. 

General Nutrition & Benefits

Watercress is very high in antioxidants, and as well packed with vitamins such as A, C, and K. It’s also rich in calcium and manganese. It’s considered to be one of the more nutrient-dense food compared to other microgreens. The reason is that they are very low in calories and hold a very high amount of nutrients.

How to Grow Cress Microgreens

Watercress is easy to grow and ready to be harvested already after 10-12 days. The seeds are small, and they are mucilaginous, same as chia seeds. It means that they create a jelly substance as they swell in water, producing a gel-like mass. 

You don’t have to presoak the seeds, but you should keep them well moist. They are best planted in soilless mediums such as coconut coir. Consider watering your watercress twice a day, in the morning and evening. You can both give them mist from above and water from underneath your tray.

The results are a crop of wonderful nutritious microgreens!
