Seed sowing and Seedling raising course of Catharanthus roseus

The seeds of Catharanthus roseus are collected from August to October every year, and the seeds should be collected along with the maturity, so as to avoid the seeds being scattered and lost everywhere. In spring, when the temperature reaches 20 ℃, we can take out the harvested seeds and sow them. Because this season, this temperature environment is very suitable for Catharanthus roseus sowing and seedling. Next, the editor will share with you the sowing course of Catharanthus roseus.

Operation methods / steps:

1. Prepare the seedling box, and then put the nutritious soil in the box, then put the right amount of water in the water plate, and the depth should be between 1 + 3-1 + 2 of the water plate. Finally, put the nutritious seedling box on the water plate.

2. Use a small stick to poke a small hole in the nutrient soil of each nursery box with a depth of 0.5 cm, then sprinkle 1-2 seeds of Catharanthus roseus in all the pits, and cover the pit with soil after sowing. The soil thickness is about 1 cm.

3. All the pits are covered with soil and watered thoroughly, then the lid of the seedling box is closed, and then wait for the seeds to germinate.

4. The germination of many seeds can only be realized in the environment of avoiding light, and so is the seeds of Catharanthus roseus. Therefore, after pouring water, we should cover the seedling box with an opaque shield in time to ensure that the seeds can germinate smoothly in the dark environment. Of course, you can also put the nursery box in a closed box, as long as it can be completely hidden from the light.

5. After the measures to avoid light are done, put the nursery box in a cool and well-ventilated environment. If nothing happens, it will sprout in about 1 week. After the seeds germinate, let the nursery box be taken out and maintained in an environment that can receive light. When the seedlings spit out 2-4 pairs of true leaves, we can plant them in pots.

6. Catharanthus roseus likes the sun and grows better in a warm environment, especially during the growing period, we should provide it with as much light as possible. At the same time, in order to improve the ornamental effect of potted plants, after Catharanthus roseus seedlings are potting, we also need to take management measures such as coring, topping, pruning and other management measures to promote the rapid growth of plants, but also sprout more lateral branches and make the plant shape more beautiful. more flowers of higher quality.
