How to keep Costus Erythrophyllus.
Light
Blood red spiral costus originates from habitats like forest understories or rocky areas, where it is naturally shaded. It prefers partial sun but can tolerate both full sun and full shade, showing its adaptable, hardy nature.
Water
Blood red spiral costus, native to humid environments, excels at absorbing and retaining moisture. It thrives in evenly moist soil and typically needs watering every 1-2 weeks.

It does not tolerate abrupt temperature changes and prefers a stable thermal environment, so avoiding temperature fluctuations indoors is important. It generally cannot endure cold and needs higher temperatures to grow. If the ambient temperature falls too low, the plant may stop growing or even die.
Fertilizer
