1、 Rhizome cutting propagation:

1. The first thing we need to do is to dig out the underground stem blocks of the plant, then clean the sludge on the rhizome with clean water, and then cut the stem blocks into blocks with a knife, about 3 to 4 buds per block

2. Prepare the soil for sprouting. This plant likes fertile, slightly acidic, loose and sandy soil with good drainage. We'd better prepare this kind of culture soil for it

3. This plant is very afraid of drought, and it can grow by the water. It is not afraid of water logging, but very fond of humid environment. Therefore, we should water the soil, and it is best to diffuse the excavated surface

4. Then bury the tubers. The spacing of each tuber should be up to 40 cm long, because this plant can grow very tall

2、 Cutting propagation:

1. If this method is adopted, it can generally be carried out at the end of August or early September. Use scissors or insert the branches into the water immediately after cutting them off. Because you can't leave the water in this way, you must cut it at any time and insert it at any time

2. Generally, the water level on the cutting seedbed is three to five centimeters high. After about 20 days, it can grow roots

3. If it is planted out of the ground, you can choose to dig a hole at the edge of the pond or next to the fake rocks where there are some low-lying places prone to ponding; If you want to plant it in a basin, you can choose a container with an inner diameter of about 50 to 60 cm, preferably one that will not leak. After planting, you should often water it, and be sure to keep the soil moist and the water level of shallow water

3、 Precautions

1. After it grows, raise the water temperature in time, because it likes warmth and is afraid of cold

2. Timely remove the surrounding weeds so that the plants can absorb nutrients

3. If the light is too strong, shade appropriately
