Ruellia tuberosa, commonly known as Minnie Root or Fever Root, is a tuberous geophyte native to tropical regions of Central and South America. It is known for its attractive purple flowers and its ability to thrive in seasonally dry climates. The plant has a dormancy period during the dry season.
Ruellia tuberosa requires bright, direct sunlight for optimal growth. It thrives in moderate temperatures and prefers a humid environment. Water the plant sparingly, allowing the soil to dry out almost completely between waterings. Ensure good air circulation to prevent fungal issues.
土壌
Ruellia tuberosa prefers well-draining loamy soil. The soil should be kept relatively dry, especially during its dormancy period. A mix of loam with some sand can help improve drainage and prevent waterlogging.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks. Avoid fertilizing during the dormancy period.
植え替え
Repot Ruellia tuberosa every 2-3 years or when the plant outgrows its container. Choose a slightly larger pot with good drainage. Repot during the growing season, and be gentle with the tuberous roots to avoid damage.
伝搬
Ruellia tuberosa can be propagated through seeds or by dividing the tubers. Propagate during the growing season. For tuber division, carefully separate the tubers and plant them in individual pots with well-draining soil.
剪定
Prune Ruellia tuberosa to maintain its shape and encourage bushier growth. Remove dead or damaged leaves and stems. Pruning is best done during the growing season.
毒性
Ruellia tuberosa is not known to be toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to prevent any accidental ingestion.
追加
Ruellia tuberosa is relatively easy to care for but requires attention to its watering needs, especially during its dormancy period. It can be grown both indoors and outdoors, making it a versatile addition to any plant collection.
