Five-petal plum: also known as Four Seasons plum, also known as Ririchun, Ririxin, Rishun, Catharanthus roseus, Four Seasons Spring, Five-petal plum, Yanlaihong and Tiantiankai.
Five-petal plum is easy to raise because it is a drought-resistant flowering variety among all flowers.
Plums can be kept at home, not in the living room. As the old saying goes, plums have four virtues of Five Blessingg, which is in line with the five elements of geomantic omen, and it is more meaningful to plant them in the courtyard.
Plum blossoms are mostly kept in the study or living room, with bright red plums and noble Bai Mei, which have high ornamental value. So, how can five-petal plums grow well at home?
First, protect the environment:
Catharanthus roseus likes sunshine, tends to high temperature environment and has good adaptability to the environment, so it is planted in both north and south, and it is very easy to survive.
The curing time is very random, except that it is below zero in winter and above 38 degrees Celsius in summer, and it can be cured in sunny environment.
It should be noted here that the ultimate tolerance of potted plants and ground plants is different. The optimum curing temperature is between 10 and 35 degrees Celsius.
It is easy to feed Catharanthus roseus, but if you want to bloom more, you must keep the ambient temperature above 22 degrees Celsius and the illumination time above 8 hours.
Second, planting soil:
Catharanthus roseus root system is semi-fleshy, but it is very developed and has high adaptability to soil. It can grow well in slightly acidic soil and neutral soil, but potted Catharanthus roseus is limited by less flower soil and less flowerpot space.
In order to give soil the best physical properties, it is suggested that Catharanthus roseus can be planted with mixed soil, 1/3 of pastoral soil+humus soil+river sand.
Third, reasonable watering:
Catharanthus roseus is also very drought tolerant. When planting, as long as the drainage problem of flower soil is well handled, watering is extremely simple, as long as it is "watered thoroughly without watering".
Catharanthus roseus has great flexibility in watering. These plants are often wet, tall and have big leaves. Dry plants are short and have short branches, but they can bloom more. In summer, it is no problem to wait until the leaves droop slightly before watering.
Fourth, fertilization:
Catharanthus roseus is barren, but if it is given the right amount of fertilizer and water, it can grow very luxuriantly and bloom a lot of flowers.
As long as the temperature is not higher than 32 degrees Celsius and not lower than 10 degrees Celsius, fertilization can be carried out. A small amount of organic fertilizer can be buried in the flower soil every month.
One month before flowering or half a month after flowering. The composition of fertilization can be biased towards "phosphorus and potassium" elements.
You can also follow the daily fertilization method, and then use "potassium dihydrogen phosphate" for foliar spraying. Fertilizers with partial phosphorus and partial potassium can promote root growth, promote flowering and add beauty to flowers.
