How to raise Catharanthus roseus in winter

Catharanthus roseus is a perennial plant, which can bloom for many years and inoculate for many years, but many friends raise it as an annual herb, leave it alone in winter, let it perish, and re-sow and raise seedlings in the coming year. In fact, the ornamental value of Catharanthus roseus will be better, so that after overwintering, it can produce more beautiful flowers in the coming year, so how to raise Catharanthus roseus in winter? Let's take a look.

1. Indoor maintenance

In general, Catharanthus roseus is maintained outdoors so that it can better absorb the public and maintain good ventilation, but in late autumn and winter, when the temperature drops, it is placed outdoors for maintenance, which is extremely vulnerable to low temperature freezing. Therefore, it is necessary to move the period to indoor maintenance in winter, and control the room temperature above 10 degrees at the same time, so that it can survive the winter safely.

2. Increase the illumination

When breeding indoors, it should also be placed in a place where it can be illuminated by the sun, so that it can receive sufficient light, so that it can better carry out photosynthesis. And sunlight can also increase the ambient temperature to make it grow better. If there is no light in cloudy days, the light can be used to replenish the light of Catharanthus roseus artificially.

3. Fertilizer and water management

The demand for fertilizer and water of Catharanthus roseus in winter will be greatly reduced, so we should pay attention to control the application of fertilizer and water during maintenance, generally choose to water it once a week, and need to irrigate the water whose temperature is close to room temperature at noon when the temperature is high, so as to avoid the decrease of soil temperature caused by too low water temperature, which is very disadvantageous to plant growth. A long-acting base fertilizer can be applied before the beginning of winter, and then an appropriate amount of phosphorus and potassium fertilizer can be applied to make it have sufficient nutrients to survive the winter.

4. Pruning branches and leaves

The branches and leaves of Catharanthus roseus are very dense, so it is necessary to prune the branches and leaves of Catharanthus roseus in winter, mainly to cut off the thin branches, disease and insect branches at the top of the plant, and cut off the over-long branches above, so as to avoid excessive consumption of nutrients and save nutrients. Make it safe to survive the winter.

5. Bagging to increase temperature

In winter, you can put a plastic bag on the flowerpot for heat preservation, so as to avoid cold wind and temperature drop, so that it can grow normally, or it can be covered with plastic film to form a small greenhouse to protect it from freezing damage.
