You can also start new poinsettias using the cuttings and some rooting hormone. Dip the cuttings in the hormone powder and place in moist quality potting soil. Make sure the new plants are well watered. The poinsettia can be placed outdoors after all danger of frost is over and the night temperature is above 60 degrees. If you put your plant outside, choose a shady place at first until the plant is acclimated to the sun.
Plants get sunburn just as humans can.
If you choose, you may sink the pot directly into a flower bed turning it about a quarter turn each week to prevent rooting through the bottom and promote even exposure to the sun. During the summer, fertilizer can be increased to once every two weeks. To encourage a bushy plant with lots of flowers, pinch or cut growing shoots to promote branching off every 3-4 weeks. Make sure you leave two or three large fully expanded leaves below the pinch. Continue this practice until mid-August.
