How to grow periwinkles in winter

There is a heating maintenance method: it is not the seedlings that are born in that year that need to be cut off the long branches and diseased branches in time after November. Change the soil once a year to ensure sufficient nutrients in the soil. There is no heating maintenance method: the temperature should be kept at about 10 ℃, and attention should be paid to heat preservation when the temperature is low at night. In the daytime, it can be put in the place with sunshine, and after flower withering, it can be applied with P and K fertilizer at noon on a sunny day.

Maintenance method with heating

sowing

Changchun flower generally matures from August to October, and can be picked and sown in the year of mature monkey. When the seed matures, it is very simple to scatter the seed in its own flowerpot, press the seed into the soil, and slowly grow a young seedling. When the young seedling grows to 3-4 leaves, it can be transplanted into a flowerpot with fertile soil, and water once every 3-5 days.

Basin soil requirements

It's better to choose the soil rich in humus, so that after the seedlings survive, they can bloom from May to November of the next year, with flowers every day. If the soil is not very rich, it can be properly applied with phosphorus and potassium fertilizer to promote the flowering of plants, but in winter, as long as the temperature is appropriate, the seedlings will grow well.

Maintenance in winter

If it is not the young seedling that was born in that year, after the flower withered in November, because the nutrients were exhausted, the branches will be gradually thin, and the leaves will move upward from the root. At this time, trim in time, and cut off the long branches and diseased branches.

It is necessary to change the soil. Usually, Changchun flower needs to change the soil once a year to ensure sufficient nutrients in the soil. If the soil is changed in time, there is no need to apply fertilizer, and the nutrients in the soil are enough for the recovery of Catharanthus roseus.

How does the family that there is central heating in winter raise periwinkle?

Maintenance method without heating

heat preservation

There is no heating at home, the temperature is about 10 ℃, relatively good, but the temperature is low at night, we should pay attention to heat preservation, you can cover the plastic film, or put it in a transparent box. In short, it is necessary to ensure a certain temperature difference in winter, but do not freeze the plants.

Sunny

During the day, as long as it is sunny, you can put Changchun flowers in a sunny place, more sun, which is conducive to the accumulation of nutrients.

fertilization

In winter, Changchun flower needs proper nutrition. The growth of the plant will slow down after flower withering, so we can apply P and K fertilizer properly, choose a sunny noon, and water properly after fertilization.
