Euphorbia pulcherima - Poinsettia
Euphorbia pulcherima - Poinsettia
Poinsettia is most popular at Christmas but may stay ornamental until March or April. A growing area with full sun is needed. Water when the soil surface feels dry and use a house plant fertilizer according to label instructions. Ideal temperatures are 70 to 75 degrees during the day and 62 to 65 degrees at night. The plant is cut back after blooming. Cuttings may be grown into blooming plants or the old plant may be reflowered. To bloom for Christmas, the plant must be given 14 hour nights beginning in early September. Over- or underwatering, or hot or cold drafts cause leaf drop.
Propagation is by cuttings.
