You have two options, the first is to follow the instructions below;
January - March: Keep
watering the poinsettia whenever the surface is dry.
April:
Starting April 1st, gradually decrease water, allowing the plant to get
dry between
waterings. Be careful the stem does not begin to shrivel. This is a
sign the plant is too stressed and is dying. In a week or two, when the
plant has acclimated to this drying process, move it to a cool spot like
the basement or a heated garage. You want to
keep it at about 60 degrees F.
May:
In mid-May, cut the stems back to about 4 inches and repot in a
slightly larger
container, with new potting soil. Water it well. Place the newly potted
plant back into the brightest window you have and once again keep it at
a temperature of 65 - 75 degrees F. Continue watering 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. Follow fertilizer label
recommendations.
June: More the poinsettia outside, pot and all. Keep it in a partially shaded location
and maintain your watering and fertilizing schedule.
July: In early July, pinch back each stem by about one inch. This is to encourage a stout,
well branched plant. If left unpinched, the poinsettia will grow tall and spindly.
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 and back into your brightest window. Continue watering and
fertilizing.
September: Continue regular watering and fertilizing. Make sure the temperature stays
above 65 degrees F.
October
Poinsettias are short-day plants, meaning their bud set is affected by
the length
of daylight. To re-bloom, poinsettias need about 10 weeks with 12 hours
or less of sunlight per day. You will have to artificially create these
conditions and it’s crucial that you be diligent.
Beginning
October 1st, keep your plant in complete darkness from 5 pm to 8 am.
Any exposure to light will delay blooming. Use an opaque box or material
to block out light. Many people
place their plants in a closest, but if light gets in through the
cracks or if you open and use the closet, it will affect the bud set.
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 15th. Keep watering and treat your plant the way you did
when you first brought it home in bloom. If all has gone well, it
should be back in bloom and ready to begin the process all over again.
The first is too much work for me, I will just cough up another $4 for a new one next year.
