Water: The house plant should be watered weekly during the growing season. Take care to provide well-drained soil and plenty of drainage holes in the container to avoid root rot. Cut back to monthly watering during the cooler months.
Temperature: Although this plant can tolerate temperatures from 25º-100º degrees Fahrenheit, it prefers temperatures ranging from 50º – 70º degrees Fahrenheit. Ideal firesticks plant temperature range is 65º – 70º degrees Fahrenheit, so it does well year-round indoors at normal household temperatures.
Soil: Use a high quality, well-drained cactus or succulent potting soil with a pH of about 6.0.
Fertilizer: You may feed your finger plant seasonally with a controlled-release fertilizer or use a weak liquid houseplant food on a weekly basis. Mature plants do well with a 20-20-20 fertilizer. Younger plants do better with a lower nitrogen rating. Some people do not fertilize the pencil plant at all.
