How to Plant长春花 (Catharanthus roseus)
Today's article introduces how to plant and cultivate Catharanthus roseus, as well as related experience on timing and methods. Let's dive into the details.
Planting Time for Catharanthus roseus
Catharanthus roseus is best planted in spring and autumn. Specifically, in spring from March to May, and in autumn from September to October. It is also possible to plant early in a greenhouse in spring, but not in autumn, as high temperatures can be detrimental to the growth and germination of the plants.
Planting Methods for Catharanthus roseus
1. Soil Selection: When planting Catharanthus roseus, choose a loose, well-draining sandy soil. A mixture of leaf mold, peat, and perlite in a ratio of 5:4:1 is recommended.
2. Sowing: Before sowing, spray the soil with a carbendazim solution to disinfect it. Then sprinkle the seeds, cover them with a thin layer of fine soil, and water moderately. The seeds should germinate within half a month.
3. Post-Planting Management: After planting, ensure proper shading and water every three days. Apply organic fertilizer every 20 days to help the seedlings grow.
How to Plant Catharanthus roseus After Purchase
1. Soil: It is essential to use a loose and breathable soil mix for Catharanthus roseus. If the soil that comes with the plant is good, there is no need to change it, as weak plants are more prone to death.
2. Light: Ensure the plant gets plenty of sunlight after purchase. Otherwise, once it adapts to the environment, it may grow too quickly and become leggy.
3. Watering: Do not rush to water the newly purchased plant. However, once it has adapted to the environment, it should not be allowed to dry out. Water thoroughly when the soil is almost dry.
4. Fertilizing: There is no need to fertilize the plant immediately after purchase. When it starts to grow, apply a multi-element compound fertilizer two to three times a month.
5. Pruning: After purchasing the plant, continuously pinch the tips to encourage the growth of more side shoots.
How to Make Catharanthus roseus Grow Faster
1. Sunlight Requirements: Catharanthus roseus is a sun-loving plant that thrives in sunlight. Ensuring adequate light will make the leaves glossy and the flowers more vibrant.
2. Soil Requirements: Catharanthus roseus is adaptable and can tolerate poor soil but cannot grow in alkaline or compacted, poorly ventilated soil, which can cause yellowing leaves and difficulty in flowering.
3. Temperature Adjustment: Different growth stages of Catharanthus roseus require different temperatures. From March to July, keep the temperature at 18-24°C, and in winter, it should not drop below 10°C.
4. Water Supply: When caring for Catharanthus roseus, water moderately. Excessive moisture can lead to waterlogging in the pot, causing root rot.
5. Fertilizer Application: To keep Catharanthus roseus vigorous, apply a layer of base fertilizer before planting and then a compound fertilizer every 10 days during growth.
Key Points for Growing Catharanthus roseus in Pots
1. Catharanthus roseus is easy to cultivate, but the temperature during care should not be below 10°C. It can freeze when the temperature drops below 5°C, so it must be kept in a warm environment during winter.
2. Catharanthus roseus prefers high humidity, so it should be sprayed with water frequently. However, the soil should be kept moist but not wet, especially in summer and winter. Follow the principle of watering when the soil is almost dry and watering thoroughly.
