In comparison with the common knowledge of flower cultivation for most people, what are the key points to master for the cultivation of Catharanthus roseus? Detailed content will be shared next.
The leaves of Catharanthus roseus are bright green and glossy, with 5 evenly spread petals resembling plum blossoms, hence the alias "Five-petal Plum." The flowers have a fresh color and a long blooming period. Catharanthus roseus is vigorous, prefers a warm and humid climate, loves sunlight, can tolerate semi-shade, dislikes humidity and flooding, and is somewhat drought-resistant. It requires fertile sandy loam with good drainage.
① When cultivated as an annual, seeds should be sown in open seedbeds in mid-to-late April. Transplant once when the seedlings are 4-5 cm tall, and plant them outdoors or in pots when they have 6-7 true leaves. During the initial planting period, it is necessary to pay attention to fertilization and watering. Pinching 1-2 times during the growing period can promote branching.
② Sufficient sunlight will result in vigorous growth and good flowering. Conversely, insufficient sunlight may cause the plants to elongate and reduce the number of flowers. Therefore, when potting, the plants should be placed in a sunny outdoor area during the growing season.
③ Due to the long blooming period, a compound liquid fertilizer should be applied every 20 days or so during the growing period, and it is necessary to keep the potting soil moist.
④ Move the plants indoors during winter, place them in a sunny location to overwinter, maintain the minimum temperature above 5°C, and control watering.
⑤ If the room temperature can be maintained above 15-20°C, the plants can bloom.
⑥ The seeds are prone to scattering after maturity, so they should be harvested in a timely manner.
