Plant your poinsettia in an area that receives full sun most of the day. However, keep in mind that to put out flower buds, poinsettias require 14 hours of complete darkness each day for 6 to 8 weeks before flowering. Any interruption to this dark period can delay or prevent the plant from flowering. Watering & Soil. Keep the soil moderately moist at all times. Poinsettias grow best in moist, well drained, fertile soils. As long as the soil is well drained, they will grow satisfactorily in a wide range of soils, including sand, muck, marl and clay.
Conical taper is the change in the diameter of a circular solid along its length. It can be expressed in linear units such as inches per foot or as an angle.
