The plant of rose flower has the characteristic of dormancy, this is mainly because there are some inhibitors in the peel and seed coat, which lead to its dormancy.
Because the seeds of rose flower will be dormant, so the collected seeds can not germinate in time, they must be treated before sowing, so that they can germinate and can be stored in sand. Put the seeds into the wet sand, put them into the container, and then cover them with 3cm thick wet sand, keep the temperature at about 0 ℃ for 2-3 months, and then sow them.
Sowing is required at the temperature of 5 ℃ - 10 ℃. During sowing, the method of on-demand sowing, strip sowing or pot sowing can be adopted to keep the spacing of seeds at 3cm. After sowing, the seeds shall be covered with a layer of plain sand, and then be watered. Generally, about 40 days after sowing, seedlings can emerge.
Before sowing, the rose flower needs to take seeds first. In November, the mature fruits will be cut off, stored through sand storage, and seeded in January or February of the next year. Before sowing, it is necessary to speed up germination, and then it can be seeded. When sowing, use river sand as substrate. River sand should be disinfected. After disinfecting, sowing should be carried out. When watering after sowing, it is better to spray water with a kettle
When the seedlings of rose flowers keep growing, they can be transplanted when they grow to 3-5 leaves. Transplanting rose seedlings into small flowerpots, after which normal management can be carried out.
