Pointsettia Care

Initial Care

When You First Bring Your Poinsettia Home

Light
Place near a sunny window. South, east or west are preferable to a north facing window. Poinsettias are tropical and will appreciate as much direct sunlight as you can provide.

Heat
To keep the poinsettia in bloom as long as possible, maintain a temperature of 65°F-75°F during the day. Dropping temperatures to 60°F at night will not hurt the plant. However, cold drafts or allowing leaves to touch a cold window can injure the leaves and cause premature leaf drop.

Water
Water the plant whenever the surface feels dry to the touch. Water until it drains out the bottom, but don’t let the plant sit in water.

Humidity
Lack of humidity during dry season, particularly in winter, is an ongoing houseplant problem. If your home tends to be dry and your poinsettia is in direct light, you will find yourself watering it frequently, possibly every day.

 

After Christmas Care

January through March
Keep watering whenever the surface is dry.

April
Starting April 1, gradually decrease water. Allow the soil to get dry between waterings. Be careful the stem does not begin to shrivel. In a week or two when the plant has acclimated to this drying process, move it to a cool spot like the basement or heated garage. Temperature around 60°F is ideal.

May
In mid-May, cut the stems back to about 4 inches and replant into a slightly larger container, with new soil. Water it well. Place the newly potted plant back into the brightest window you have and once again keep the temperature 65°F-75°F. Continue to water whenever the surface of the soil feels dry. Watch for new growth. Once new growth appears, begin fertilizing every two weeks with a complete fertilizer following label instructions.

June
Move the poinsettia outside keeping it in a partially shaded location and maintain watering and fertilizing routine.

July
In early July, pinch back each stem by about an inch.

August
By mid-August, the stems should have branched and leafed out. Once again, pinch or cut the new stems, leaving 3-4 leaves on each shoot. Bring the plant back indoors to the sunny spot. Continue
watering and fertilizing.

September
Continue watering and fertilizing. Make sure the temperatures stay above 65°F.

October
Poinsettias are short-day plants, meaning their bud set is affected by the length of light. To re-bloom, poinsettias need about 10 weeks with 12 hours or less of sunlight per day. Beginning October 1, keep your plant in complete darkness from 5pm to 8am. Any exposure to light will delay blooming. Move the plant back to the sunny window during the daytime and continue watering and fertilizing.

November
Around the last week of November you can stop the darkness treatment and allow the plant to remain in the window. You should see flower buds at this point.

December
Stop fertilizing about December 15. Keep watering and treat your plant the way you did when you first brought it home in bloom.
