Long candles native to tropical West Africa. Hi warm, humid and sunny environments, not cold. Long candles growth temperature for 18 ~ 24 ℃, 2 ~ 10 month 18 ~ 30 ℃, 10 months to February next year for the 13 ~ 16 ℃. Winter temperature of not less than 8 ℃, 5 ℃ vulnerable to frost damage than leaf, the light caused by fallen leaves, while in young stems wither. Temperature can be higher vegetative growth, 30 ℃ over heat, just enough water, can grow normally. And reproductive growth, the flowering period the temperature should be lower, at about 17 ℃ or so. Long candles most sensitive to water. Stem and leaf growth stage to maintain the saline soil moist, but not excessive water, excessive water, resulting in not only the length of flowering vines, and even the leaves yellow and fall, root rot dead. Summer high temperature season, watering should be sufficient and appropriate shading. To reduce watering in winter, so sleep in order to secure the winter. Long candles to be light enough in winter, when hot summer weather should shade, otherwise the leaves yellow. Insufficient light will cause trailing growth, not flowers. Flower bud light cycle is not affected, but a strong light on bud differentiation and development are promoted. Should not be placed in the dark for too long, at a temperature above 21 ℃, more than 24 hours, it will shatter. Soil with a fertile, loose and well-drained sandy loam. Or peat pot with potting mixture of soil and coarse soil

Common stem, tiller and seed propagation. Propagation: often sticks _insert_ed, bud and root cuttings can be _insert_ed. Optional plug sticks on top of robust disease-free shoot branches, but also the lower part of the old branch can be cut 8 to 10 cm stem segment as cuttings. Is to take the budding branches of the lateral buds, with part of the xylem, as the cuttings. Root cuttings is the root-like rhizomes cut into 8 to 10 cm long for the cuttings. Slotting available peat, perlite, leaf mold, sand and vermiculite and other substrates, to spring and autumn, the best cutting, cutting optimum temperature is 21 ℃, slotting temperature is 26 ℃, is very beneficial for rooting. 3 weeks after _insert_ion can take root. Such as 0.5% to 0.8% IBA solution treated cuttings at the base 1 to 2 seconds, fast and multi-rooted. Division propagation: the flowers, the excavation of underground stolons on the germination of a new branch, with roots directly to pot, put half shade conservation. Seed propagation: 3 to 4 month. Seed large, with indoor sowing pots, maintained at room temperature under 24 ℃, 10 days after sowing have been germination, seedling height 10 centimeters into Xiaopen conservation, the second year will be able to blossom.

Long candles used pot 12 to 15 cm pots, pot can be planted 3. Growing need plenty of water, such as soil moisture is too large, will cause yellow leaves fall off, if the branches do not wither, stop watering, let it recover, sprouting new leaves. 1 per half fertilization, Long candles flowering season, Adding 1 or 2 times P and K, or "flowers" Friends of Four Seasons 20-8-20 fertilizer with high potassium. Winter, reduce watering and stop fertilizing. Long candles to create a beautiful plant type, cuttings or seedlings in the pot to 15 centimeters long after, 10 cm away from the pot cut-off branches to promote the germination of thick new branches. Growing season is necessary to strictly control the branch level, attention topping topping, in order to branch neat, dense flowering future. In the latter half of topping, the application of CCC than for a long time or to control plant height, to strains of short, leafy, flowers and more. Huanpen every spring when the branches on the shoot pruning stubs, so that plants round, shoot more, spend more.
