How to cultivate green watercress

Propagation method: Branch cutting (branch cutting, leaf cutting) can be used for propagation.

Branching method: when the plant is full of pots, pour it out and plant it in several pots.

Cutting method: terminal bud cutting has the best effect. Generally, biennial branches with the length of 8- 10 cm are selected from May to June. There are 3 nodes, which are truncated at 0.5 cm below the nodes. There are 3-5 leaves on the upper part, and they are kept in a ventilated and cool place 1-2 hours. After the incision is slightly dry, cut it into semi-cultivated soil of humus soil and garden soil, pour enough water and place it in the shade. Keep the soil moist frequently, and it can take root after 20 days. When the roots grow to 3 cm, they can be maintained in pots.

Leaf inserting method: May is the best in East China every year. Take healthy and mature leaves from the middle and lower parts of the plant, and take off the whole leaves with petioles. After drying for half a day, insert the petiole into a shallow basin filled with frog stone or sand at a 45 angle and keep it moist. When the temperature is about 25℃, the root system can be produced in about 25 days, and when there are 3-4 leaves, it can be potted for maintenance. When inserting leaves, it is forbidden to cover the basin mouth with plastic film or glass for moisturizing, otherwise it will easily cause rot.
