1. Sow

Watercress that can be bought in vegetable market can be directly used for cutting, and the old stems are better. If there are adventitious roots, it is easier to survive. The stem of watercress is cut into small pieces of about 10 to 15 cm, and each piece has about 3 to 5 knots. The cuttings are inserted into the soil with a depth of about 3 to 5 cm, preferably half-lying, so that the stems are as close to the soil surface as possible and watered, and it is best to maintain the water level of about 1 cm. If you want to plant ramets, it should be done about one month after cutting, and the spacing is about 10 cm.

2. Daily management

Watercress is moist to avoid drought. It is often necessary to water the soil to keep it moist. When planting watercress, it is best to plant water, and the water level is relatively shallow.

More fertilizer is needed, but it is best to apply all-element fertilizer and decomposed organic fertilizer once every harvest. There are fewer pests and diseases in paddy fields, and manual elimination is one of the main reasons. If the pests are more serious, plants may be flooded, and water will be discharged after the pests are drowned.

Step 3 harvest

Cress can be harvested at about 20 cm.
