How to plant vinca roseus? Planting time and method

Vinca roseus planting time

It is best to plant Catharanthus roseus in spring and autumn, specifically March to May in spring and September to October in autumn. It can also be sown in advance in the greenhouse in spring, but not in autumn because the temperature is too high, which is not conducive to the growth and germination of the plant.

Vinca roseus planting method

1. Soil selection: When planting Catharanthus roseus, you need to choose sandy soil with loose soil and good water permeability. You can use leaf mold, peat and perlite in a ratio of 5:4:1.

2. Start sowing: When planting Catharanthus roseus, you need to spray the soil with carbendazim liquid for sterilization and disinfection, then sprinkle some seeds, cover with a layer of fine soil, and water it appropriately. After half a month, the seeds will take root and sprout.

3. Planting management: After planting Catharanthus roseus, you need to provide it with shade, water it every 3 days, and apply organic fertilizer every 20 days to help the young shoots grow.

How to plant the newly bought periwinkle

1. Soil: When growing Catharanthus grandiflora, you must prepare loose and breathable soil. If the soil is of good quality when you first buy it, there is no need to change the soil, otherwise the plant will grow weakly and easily die.

2. Light: When you first buy vinca roseus, you must give it plenty of sunlight, otherwise it will grow very quickly after adapting to the environment and become too tall.

3. Watering: Don’t rush to water the newly purchased vinca, but it must not lack water after it adapts to the environment. Generally, water it thoroughly when the soil in the pot is almost dry.

4. Fertilization: Don’t rush to fertilize Catharanthus roseus when you just buy it. When Catharanthus roseus blooms and grows, add fertilizer two to three times a month. You can use multi-element compound fertilizer.

5. Pruning: After buying vinca, you should constantly top the plant when it starts to grow. If you don’t top it, it will not produce more side buds.

How to grow vinca roseus fast

1. Sunlight requirements: Catharanthus roseus is a light-loving plant and likes to grow in the sun. Sufficient light must be ensured during the growth period so that the leaves become shiny and the flowers become brightly colored.

2. Soil requirements: Catharanthus roseus has strong adaptability and can tolerate barrenness, but it cannot grow in alkaline soil or in compacted, airtight soil, which can easily cause the leaves to turn yellow and make it difficult to bloom normally.

3. Temperature adjustment: The suitable temperature for Catharanthus roseus is different in different growth periods. It should be kept at 18-24℃ from March to July, and should not be lower than 10℃ in winter.

4. Water replenishment: When caring for Catharanthus roseus, you do not need to replenish too much water. If it is too wet, water will accumulate in the pot, causing the roots to rot.

5. Fertilizer supplement: If you want to maintain Catharanthus roseus more vigorously, you can cover it with a layer of base fertilizer before potting it, and then apply compound fertilizer every 10 days during its growth.

Precautions for potted cultivation of Catharanthus roseus

1. Catharanthus roseus is a relatively easy flower to cultivate. The temperature during maintenance should not be lower than 10 degrees. If it is lower than 5 degrees, it will be frozen, so it must be kept in a warm environment in winter.

2. Catharanthus roseus likes high humidity, so you need to spray more water when maintaining it, but the soil should not be wet, especially in summer and winter. Just maintain the principle of watering when dry and watering thoroughly when watering.
