What plant is Sedum rubrotinctum? Characteristics, growing methods and precautions
Sedum rubrotinctum, also known as jelly bean plant or corn kernels (commonly called grape palm in the market), is a small succulent plant. Its leaves are fleshy, oblong-elliptical, about 1 cm long, and alternate. The flowers are yellow and star-shaped. In autumn and winter or under strong light, the leaves turn partly or entirely bright red. The leaf tips are slightly translucent, and at this time the leaves are a mix of red and green, with vivid colors, like a rainbow or jade, hence the name.
Growing methods for Sedum rubrotinctum
Sedum rubrotinctum prefers an environment with a clear temperature difference between day and night. It has strong adaptability to temperature and can grow well between 10°C and 28°C. In autumn and winter, as the temperature drops and light increases, the fleshy leaves gradually turn red, so artificially lowering the temperature during cultivation can increase its ornamental value.
Sedum rubrotinctum has high requirements for ventilation, and it is best to use a highly breathable pot such as red terracotta.
It prefers sunlight and does not need too much water. After sunlight hours increase, the whole plant turns red and grows upward. For old plants that have become woody after many years, be sure to pay attention to the amount of watering, as too much water will cause the branches to rot.
To grow Sedum rubrotinctum well, just master the following 5 key points:
1. Temperature:Sedum rubrotinctum prefers a warm environment and is afraid of cold. In winter it should be kept above 6°C. Since the color is most beautiful when the winter temperature is around 10°C and there is plenty of sunlight.
2. Light:Sedum rubrotinctum prefers light and is not shade-tolerant. A shaded environment easily causes leggy growth, and over time it will weaken and even die. In summer, attention should be paid to shading.
3. Watering:Sedum rubrotinctum is relatively drought-tolerant and afraid of waterlogging. Watering must alternate between dry and wet, and do not water when it is not dry!
4. Fertilizing: Sedum rubrotinctum is afraid of heavy, concentrated, or raw fertilizer, so it is best to apply a small amount together with watering.
5. Other:When caring for Sedum rubrotinctum indoors, rotate it 180 degrees about every 2 weeks to prevent uneven growth, and that is it.
Sedum rubrotinctum has few diseases, but leaf spot and stem rot occasionally occur.
Leaf spot is mainly caused by poor ventilation and high air humidity. Systemic fungicides can be used for prevention and control. Improving ventilation is the key to preventing leaf spot.
Stem rot is mostly caused by an overly humid environment in winter. Healthy upper stem segments of the plant should be cut for propagation, while avoiding excessive and frequent watering in winter and keeping the potting soil slightly dry.
