Watercress packs some nutritional value making it a healthy edible. It is rich in Iron, Calcium, folic acid, and some essential vitamins. Naturally, it grows along streams and waterways but most importantly, it also needs a little sunlight to thrive luxuriantly.
Watercress is a household grocery leaf used for salads and sandwiches so it will be common in grocery stores. Head down to one of the stores and buy a substantial amount of the stems.
When you’ve gotten the stems, you need to strip off the leaves so you can know you are making progress when the new ones start to germinate. Stems are propagated bare or planted bare like cash crops.
It doesn’t need to be waterlogged, it can be flowing water, the background should just be made of water. This doesn’t mean the environment should be flooded or you should use an ocean. What you will be doing, in essence, is replicating the natural habitat for watercress in your home.
3. Provide the Enabling Environment for Growth (Pot or Container)
Let’s say you are using a container. Pick a container that has some drainage outlets and is at least 6 inches deep. Include a layer of landscaper’s cloth at the base of the container.
You don’t need earthen soil here, however, you can use a soilless mixture that drains very well. The soilless mixture should contain peat moss and vermiculite or perlite.
