Candlestick plants grow best in full sun locations with at least six hours of direct sunlight. This plant also likes temperatures above 65 degrees Fahrenheit, so place it in the warmest micro-climate in the garden. Suitable soil ranges from average to poor quality, but it must drain well. Wet soil causes the roots to start to rot. This plant enjoys dry conditions.
During the first summer, the candlestick plant needs regular watering while developing strong roots. This plant is very drought-tolerant once it is established and mainly lives off rainfall. If the weather is hot and dry, water deeply in the middle of summer.
The branch tip of new growth is pinched back on young plants to encourage the development of branches and flower spikes. In the early spring each year, cut the plant back to the desired size to maintain a compact shape. Remove any dead branches after new growth begins.
Seed from the candlestick plant is harvested in the fall. Save the seeds in case of a winter freeze, which will kill this tropical plant. To germinate the seeds, start them indoors in February or March. Soak the seeds overnight in warm water. Refreshing the water every few hours increases the success of the germination process. Plant the seed in trays of damp peat moss. Once the date of the late spring frost is passed, plant the evergreen seedlings outside in their permanent locations.
