have two poinsettias that I put in my garden this year. They are
doing very well and have really gotten big in the last two weeks. I
want to take them in for the winter and make them rebloom. How is the
best way to do that?
is a popular plant around the holidays. It's prized for its bright
red colorful bracts. Although red is the most popular color of
poinsettia, there are also white, pink, and spotted or marbled types.
You can make poinsettia rebloom yearly and here is how to care for a
poinsettia starting this autumn.
Believe it or not, it's now time to start thinking about Christmas,
even though it's over three months away. To make a poinsettia rebloom
in time for the holidays, begin a dark treatment in late September.
Place the plant in complete, uninterrupted darkness for 14 hours a
day, for example from 6 p.m. to 8 a.m. The plant cannot be exposed to
any light during this time, even streetlights or lamps. Place the
plant in either a dark closet or put a box over the plant. During the
day, move the plant to a sunny location. Continue the dark treatment
until bracts begin to show color, usually in about eight weeks. Color
should be visible by late November.
After Christmas, when the colored bracts have faded and fallen off,
cut the plant back by two thirds. Reduce watering so that the soil is
almost, but never completely, dry. Keep the dormant plant at normal
room temperature in bright, filtered light.
Begin regular watering again in April. New growth should begin to
show when watering resumes. Pinch back new growth to keep the plant bushy.
Repot the poinsettia when new growth starts. Choose a pot the same
size as the original one. Shake off all the old potting soil and
replace with fresh, soil-based potting soil. Begin fertilizing once
every two weeks with a liquid fertilizer once the plant is repotted.
Continue feeding until September. When night temperatures are above
60 degrees, place the plant outside in a partially shaded area. Be
sure to bring it back inside in September before frosty weather and
repeat the process.
