it's not fertilizer that does it. It's light.
From October to Thanksgiving, you have to put the things in a closet with grow lights on a timer, so that they get EXACTLY 10 hours of light and 14 hours of TOTAL DARKNESS. That's the key.
The rest of the instructions are to start allowing the plant to grow gradually dry starting in April. (not bone dry, just dry-ish). Then store in 60 degree, airy location. Mid-May, prune plant to four inches above soil level. Re-pot. Place in very bright window, with temps between 65-75 degrees, and water when the soil surface is dry. After new growth appears, fertilize evert two weeks. In June take outdoors, in a lightly shaded location. Water and fertilize as before. Pinch one stem in early July. Allow 3-4 leaves to remian on each stem between mid August and September 1st. Bring indoors in September.
In October - begin the regimented Light and Dark procedure to get the brachts to change color.
It's more trouble than looking after a toddler, if you ask me.
Good Luck.

color is determined by the variety of poinsettia you have if you have a pink one it will always be pink a white one will always be white. you can't change the color with fertilizer. hope that helps a little. to make it "bloom" you flower the advice in the other posts.

sorry - it is not the fertiliser but the amount of light that does it.
