How to Grow Watercress Step by Step: Everything You Need to Know

Before we get into how to grow watercress, let’s see what we are talking about when we talk about watercress.

Its scientific name is Nasturtium officinale but it is also commonly known as watercress, water cress or water cress. It belongs to the Brassicaceae family.

Watercress is a plant that grows spontaneously near streams, places with stagnant water or marshes (it is therefore said that watercress is an aquatic or semi-aquatic plant), so in ancient times it was considered a weed.

As mentioned above, watercress are plants that need to grow in places where there is water. That is, they constantly need the presence of water. However, we must be careful that animals such as cows or sheep do not drink from this water, as they can transmit diseases.

Therefore, we have 2 possibilities when deciding where to sow watercress:

Sow watercress in the wettest places in the vegetable garden.
Sowing watercress in pots: placing a bowl of water under the pot.

Another possibility is to buy fresh watercress and put it in a plastic bag (perforated) with soil. Put that bag in a pot and under the pot put a bowl with water.

  1. Watercress care

For the cultivation of watercress are recommended clay soils, rich in humus. With a depth of about 15 centimeters.

The best are shady places so that they do not get too much light.

As mentioned above, watercress needs a lot of water, so watering should be abundant, always keeping the area very moist.

In addition, if the plants bloom you should cut the flowers before harvesting.

  1. Harvesting watercress

Watercress should be harvested after about 2 months. When the plants are about 15 centimeters long. When harvesting, the side shoots should be removed.

To avoid damaging the roots, the cut should be made at about 5 centimeters.

Once we have harvested the watercress, it is recommended to wash them with cold water and consume them at the time. On the contrary, if we want to use them later, we wait for them to dry and put them in the refrigerator.
