Flowering Vinca
I. Soil
Flowering vinca has a strong adaptability and does not have strict soil requirements. It prefers fertile, loose, moist, humus-rich sandy loam. For potted plants, it is recommended to use a mixture of leaf mold soil, garden soil, and river sand as the growing medium.
II. Light
It enjoys light but can tolerate shade. In the hot summer, to prevent leaf burn, it needs to be shaded and protected from direct sunlight. A semi-shaded environment is ideal. In阴暗 places, the yellow spots on the leaves become lighter, so it is suitable to plant under sparse trees.
III. Temperature
It prefers warm conditions but can also tolerate cold, surviving temperatures as low as 0°C in winter.
IV. Watering
Water during dry spells and ensure drainage during the rainy season. The pot bottom should not have standing water. As it grows rapidly, watering should be adequate during the growing season, and the potting soil should be kept moist.
V. Propagation
1. Division
Division is best done in spring. Cut off the old branches from the previous year, dig up the plant, straighten the roots, and use a sharp knife to separate them, taking care to maintain the root system. Plant the divided plants in separate pots and water thoroughly.
2. Cutting
Cuttings can be taken throughout the year. The growing medium can be a mixture of pearl rock, vermiculite, sand, etc., with good water retention properties. In autumn and winter, cuttings should be taken in a greenhouse or on a balcony; in winter, to ensure root formation, greenhouse cuttings are recommended.
