What are the breeding methods of five-petal plum?

Five-petal plum, also known as Catharanthus roseus, resembles plum blossom and has a long flowering period. it is a common flower in the south of the Yangtze River. It is mostly used for potted plants, so what are its breeding methods? How to maintain it?

What are the breeding methods of five-petal plum?

Five-petal plum can be propagated by sowing or cutting, but it is generally used to sow and propagate. Because the seedling growth of cutting propagation is not as strong as that of sowing seedlings.

How to maintain the five-petal plum?

1. Light and temperature

Five-petal plum likes high temperature, high humidity, tolerance to semi-shade, not resistant to cold, the most suitable temperature is 20 ℃-33 ℃, like sunshine. Therefore, during maintenance, the sun should be sufficient, the temperature should be between 20 and 32 ℃, and the overwintering should be kept above 12 ℃.

two。 Water and fertilizer management

In the high temperature and rainy season, a large number of plants often die because of the epidemic disease induced by high temperature and humidity, so the leaves should be kept dry as far as possible in the process of cultivation, and the cultivation medium should not be watered up. 20-10-20 and 14-0-14 water-soluble fertilizers should be used for fertilization, and the concentration of 200-250ppm should be applied alternately every 7-10 days. When the temperature is low in winter, the use of 20-10-20 fertilizer should be reduced. If the ordinary soil is used as the medium, the compound fertilizer can be mixed as the base fertilizer before the medium is put into the basin. When the fertility is insufficient, then apply water-soluble fertilizer.

3. Pruning

In general, coring begins when 4-6 true leaves (8-10 cm), and when 4-6 leaves grow from new shoots (15-20 days after the first coring), the second coring should be carried out no more than 3 times (more than 3 times will affect the quality of flowering). The last coring of Catharanthus roseus has a direct impact on the flowering period. generally, the last coring in autumn (National Day flowers) is 25 days from the early flowering stage, and the last coring in summer is 3-5 days earlier than that in autumn.

As the five-petal plum plant itself is poisonous, so the occurrence of diseases and insect pests is less, but we should still pay attention to the control of red spiders, aphids, base rot, black spot and so on.
