Master 7 maintenance skills, bloom all year round;
1, Catharanthus roseus cultivation does not require much soil, and it is a potted plant that likes fertilizer. You can choose more fertile humus soil and add some river sand, which not only ensures soil nutrition, but also has good air permeability and drainage performance. If the soil is barren, the number of branches, leaves and flowers is small, and the leaves are easy to turn yellow, we must choose fertile soil to cultivate Catharanthus roseus.
2, Catharanthus roseus, spring and autumn are the growth period of Catharanthus roseus. At this time, we must let Catharanthus roseus get enough light, otherwise it will grow slowly, with few flowers and not good enough. It is best to put it on the balcony or outdoors for maintenance, so that the buds of Catharanthus roseus will always bloom, especially bright, and the leaves are oily and green, which is especially beautiful.
3, Catharanthus roseus is afraid of water accumulation, so pay attention to the amount of water when watering. Watering times should not be too much, otherwise it will not only affect the growth of Catharanthus roseus, but also lead to root rot. It is best to water the soil after it dries. Don't worry that Changchun flower will be short of water, because it is a tropical flower. If the temperature is too high in summer, you can water more, otherwise the leaves will curl.
Catharanthus roseus likes warmth and needs to be placed in a slightly dry and sunny environment. The suitable growth temperature is 18~24℃ from March to July, 13~ 18℃ from September to next year, and not lower than 10℃ in winter. Therefore, friends in the north should pay special attention to keep the Catharanthus roseus warm in winter!
5, Catharanthus roseus fertilization, you can alternately apply compound fertilizer and liquid fertilizer every ten days. In order to ensure sufficient nutrient content in the flowerpot soil, a layer of base fertilizer can be sprinkled on the bottom of the flowerpot soil. After all, the lovely Catharanthus roseus still needs nutrition!
Catharanthus plants are poisonous, so they are more resistant to pests and diseases. Seedling diseases mainly include gray mold and seedling blight. In addition, it is necessary to prevent the damage of fertilizers and chemicals to fertilizers at seedling stage. If this happens, you can wash the basin soil with clear water to reduce the accumulation of fertilizer, strengthen ventilation and reduce the harm.
Catharanthus roseus is most prone to stem and leaf rot in rainy season, which is caused by epidemic virus. Once the mortality rate of pests and diseases is high, it will seriously affect large-scale planting. Chemical control method: before rain, use 1% bordeaux mixture or 600 ~ 800 times 65% good organisms for protection. Spraying 600 ~ 800 times of 72% Kelu or 600 ~ 800 times of 25% Prixim once a week has a good control effect.
7. Catharanthus roseus is a kind of herb, which is suitable for potted plants. But be careful not to let the plants grow too high, which will affect the viewing. After the flowerpot is put away, pick red hearts many times to promote more flowers. After the flowers fail, the residual flowers should be cut off in time to avoid more nutrient loss.
