Sow

Although the seeded seedlings will bloom slowly, the seeded seedlings will be healthy and strong, and look more assured. However, the sowing method is not easy to survive. Where the sowing conditions are not very good, flower friends can use cutting propagation. However, when there is no mother plant, you can only buy seeds to sow

Most seeds are sown in spring. The seeds of longtuzhu are large. They can be soaked in warm water for 12 hours before sowing. The on-demand sowing method is adopted, and the plant row spacing is 3 × 5 cm. Seedlings can emerge in 10 days at 20-25 ℃. 3-4 leaves are transplanted once, and when the seedling height is 10 cm, it is put into the pot, with 1-3 plants in each pot, and it can bloom in the second year

Sowing can be sown in shallow pots from March to April every year, the temperature is maintained at 24 ° C, the seedlings can emerge in 10 days, the pots can be changed when the seedlings are 10 cm high, and the flowers can bloom in the second year

Cutting

Cutting is generally carried out in spring and autumn. Cutting can adopt branch cutting, leaf bud cutting and root cutting

Branch insertion: the robust annual branches can be selected and cut into 2-3 sections. The top leaves can be retained and cut off 1 / 2. They can be inserted into plain sandy soil, maintained in the shade and kept wet. They can take root in 20 days and be planted in pots after 35 days

Leaf bud cutting: take the lateral buds on the branches as cuttings, take a small section of branches when cutting, and then cut them in the matrix. The buds are exposed outside the matrix, and can take root after shading and curing for 20-25 days. After the leaf buds germinate, they can be put into the pot

Root cutting: it can be carried out in combination with changing pots. Cut the root grape stolon on the soil into 8-10 cm segments as cuttings. Peat, vermiculite, perlite, rotten leaf soil or sand with good permeability shall be selected as the matrix, but it is better to be acidic

Cutting is generally carried out from May to June every year. The top shoots of healthy and disease-free branches can be selected, and the old branches at the bottom can also be cut into 8 ~ 10 cm stems as cuttings. Budding is to take the lateral buds on the branches and take part of the xylem as cuttings. Root cuttings are rootlike stolons cut into 8 ~ 10 cm long for cuttings. The cuttings can be made of peat, perlite, saprophytic soil, river sand, vermiculite and other substrates. The best cuttings are in spring and autumn. The suitable temperature for cuttings is 21 ℃ and the temperature of the cuttings is 26 ℃, which is very favorable for rooting. It can take root 3 weeks after transplanting. If the base of cuttings is treated with 0.5% ~ 0.8% indole butyric acid solution for 1 ~ 2 seconds, it can root faster and more
