Although the seeded seedlings will blossom slowly, they will be healthy and robust, and look more reassured. However, where the sowing method is not easy to survive and the sowing conditions are not good, the flower friends can use the cutting method to reproduce. However, when there is no mother plant, we can only buy seeds to sow!
The seeds can be soaked in warm water for 12 hours before sowing. The plant row spacing is 3 × 5 cm, and the seedlings can be produced in 10 days under the environment of 20-25 ℃. 3-4 leaves were transplanted once, and when the height of seedlings was 10 cm, they were put into pots, 1-3 plants per pot, and they could bloom in the second year.
Sowing can be carried out in shallow pots from March to April of each year, the temperature is kept at 24 ° C, and seedlings can emerge in 10 days. When the height of seedlings is 10 cm, they can be transplanted in pots and blossom in the second year.
Cutting is generally carried out in spring and autumn, and can be branch cutting, leaf bud cutting and root cutting.
Branch cutting: the healthy annual branches can be cut into 2-3 sections, and the top leaves can be kept and cut off by 1 /2. The branches can be inserted into the plain sand, maintained in the shade, kept in the humidity, rooting can be done in 20 days, and potting can be done in 35 days.
Leaf bud cutting: take the lateral bud on the branch as the cutting spike, take a small branch when cutting, then cut it in the substrate, the bud is exposed outside the substrate, take root after 20-25 days of shade maintenance, and then put it in the basin after the germination of the leaf bud.
Rooting: it can be carried out in combination with basin changing. The rhizome of staphylon on the soil can be cut into 8-10cm segments as the cuttings. The matrix should be peat, vermiculite, perlite, saprophytic soil or sand with good permeability, but the acidity is better.
Cutting is generally carried out from May to June every year. The top twigs of healthy and disease-free branches can be selected, and the old branches at the bottom can be cut into 8-10cm segments as cuttings. Budding is to take the lateral buds on the branches with some xylem as the cuttings. Rooting is the cutting of the root like stolon into 8-10 cm long spikelets. The cutting bed can be made of peat, perlite, saprophytic soil, river sand and vermiculite. The best cutting materials are spring and autumn. The suitable cutting temperature is 21 ℃, and the cutting bed temperature is 26 ℃, which is very beneficial to rooting. It can take root 3 weeks later. If the cuttings were treated with 0.5% - 0.8% IBA solution for 1-2 seconds, the rooting rate would be faster and more.
