Time selection: Cuttings should be carried out in a warm environment, mostly in April and May, when the temperature is suitable and the branches take root fast.
Pick cuttings: use strong apical branches, about 5 cm in length, keep 1-2 leaves at the top, or use full leaves, dry and set aside.
Prepare potting soil: Choose a wide-mouthed pot with a loose, breathable substrate and disinfected.
Cutting: Insert the leaves obliquely into the soil, cutting 1/3 of the depth of the branches, and place them in a warm, cool place.
First, the choice of time
When watercress green is cutting, it should be selected in a warm environment, and the time suitable for its growth is spring, so cuttings are mostly carried out in April and May. In the spring, the temperature is relatively high, and the air also has a certain humidity, so the environment is more conducive to its rooting.
Second, select the cuttings
When cutting, you can choose to grow a more robust top branch, no need to be too long, the length is about 5cm, keep the top 1-2 leaves, and then put the cuttings in a ventilated shade to dry, when the wound is dry to carry out cuttings. You can also use leaf cuttings, to choose a full and rounded, and disease-free leaves, the leaves should have part of the petiole, only the growth capacity of the leaves is strong, and the roots can be taken faster after cuttings.
Third, prepare the potting soil
When preparing soil, you should use a relatively wide pot with a pot mouth, so as not to overcrowd the leaves or branches of the cuttings, the soil should be loose and breathable, you can use peat soil, vermiculite and river sand for preparation, mixed and prepared to disinfect, the common disinfection method is to soak with carbendazim, you can also put it in the sun.
Fourth, carry out cuttings
When cutting, the dried leaves are inserted obliquely into the soil, and a certain distance is retained between each leaf. If the branches are cuttings, insert 1/3 of the branches into the soil, fix the branches, put the pots into a cool environment after cuttings, keep the soil moist, almost 15-20 days, the cuttings will grow roots.
