Periwinkle is also called Four Seasons Plum. When it blooms, the color is very bright, and the flowering period is very long. As long as the temperature is suitable and the sun is sufficient, it can bloom all year round. Therefore, many flower lovers like to breed. At the end of autumn and the beginning of winter, we raise a pot of periwinkle, which will bloom from spring to winter in the coming year. The flowering period can last for four seasons. This is also the origin of the name Four Seasons Plum. So how do we maintain it? Winter management
1. Warm environment
Periwinkle likes a warm environment. The suitable temperature during the growth period is 20 to 33 degrees. Low temperatures in winter are not conducive to the growth of periwinkle, so When growing periwinkles in winter, you need to pay some attention. So how do we grow periwinkles in winter?
Temperature management: The beginning of November has already reached the end of autumn and the beginning of winter. In this case, we need to do a good job in keeping warm, which will help the periwinkles survive the winter smoothly. Otherwise, if the temperature is too low, the periwinkles will Frostbite and freezing will occur, which is not conducive to the growth of periwinkles next year. Therefore, when we grow periwinkles in winter, the indoor temperature needs to be above 10 degrees. If we want periwinkles to bloom in winter, the temperature needs to be above 15 degrees, and they need to be grown in sufficient sunlight, so that periwinkles can bloom in winter.
2. Sufficient sunshine
Periwinkle likes sufficient sunshine. In summer, the sun is strong and it is not afraid of exposure. If Catharanthus roseus is kept in a shady place for a long time, the leaves of Catharanthus roseus will appear yellow and leggy. Therefore, when raising Catharanthus roseus, no matter it is spring, summer, autumn and winter, it needs to be grown in sufficient sunshine. Only then will they grow vigorously and bloom abundantly and brightly.
3. Watering is different in different seasons
Periwinkle is relatively drought-tolerant and is afraid of long-term water accumulation in the soil, which is prone to root rot. Therefore, you need to pay some attention when watering periwinkles.
Watering management: Watering of periwinkles is different in different seasons. When watering periwinkles in winter, it is necessary to water at high temperatures at noon, and the water temperature needs to be consistent with the indoor temperature to prevent the temperature difference from being too large. Resulting in unfavorable root growth of periwinkle. When watering periwinkles in spring and autumn, you can wait until the soil dries out and then water thoroughly. To water periwinkle in summer, you need to water periwinkle in the morning or evening. We can wait for 1/2 of the soil to dry and then water it once. When the weather is dry, spray water around the flowerpot frequently. During the rainy season, the frequency of watering can be reduced. And once there is too much rain in the flower pot, it needs to be drained out in time to prevent water accumulation and root rot. Management for the coming year
In the following spring, when the periwinkles begin to grow, we can move the periwinkles outdoors for maintenance later. Because of the severe cold in spring, if you move it outdoors too early, once the late spring cold occurs, the periwinkles will be frostbitten. We have already mentioned winter sunlight and watering above, so we won’t talk about it here anymore. We only talk about how to fertilize periwinkles and prune them.
〔1〕Appropriate fertilization
Periwinkle has a long growth period and large blooms, so it requires more fertilizer. But when fertilizing periwinkles, if you apply too much fertilizer at one time or use raw fertilizer, periwinkles are prone to root burn due to fertilizer damage. So how do you fertilize periwinkles? When we fertilize the periwinkle, we can apply it after the periwinkle grows vigorously. To fertilize periwinkles in spring, you can use nitrogen, phosphorus and potassium ternary fertilizer, or thin decomposed cake fertilizer and water, and fertilize once every 15 to 20 days. When the periwinkle grows buds, we can give the periwinkle a thin layer of phosphorus and potassium fertilizer every 7 to 10 days, or use Huaduoduo No. 2, or apply potassium dihydrogen phosphate water-soluble fertilizer, all of which can make the periwinkle better. The flowers bloom abundantly and brightly.
〔2〕Proper pruning
When periwinkle grows, it needs to be properly pruned. This can make the plant shape of periwinkle more beautiful. So how do we prune periwinkle? ? Usually we can promptly prune the remaining flowers after the periwinkle blooms, which can reduce nutrient loss and help the periwinkle bloom again! In winter or early spring, we can cut off the leggy, dry, and diseased branches to make the periwinkle plant more beautiful and provide ventilation and light transmission.
Grow a pot of periwinkle in late autumn and early winter. As long as you manage it correctly in winter and the coming year, you can make the periwinkle seedlings grow stronger and bloom more. The flowering period lasts from spring to winter. However, periwinkles are slightly poisonous, so you need to be careful when growing them at home. If you have children, you can keep them out of reach of children.
