| Poinsettia Care | ![]() |
Location and Temperature - The poinsettia thrives on indirect, natural
daylight. Exposure to at least six hours daily is recommended. If direct sun
cannot be avoided, diffuse with a light shade or sheer curtain. To prolong the
bright color of the poinsettia bracts, daytime temperatures should not exceed
70º F. The color of your poinsettia will last the longest with temperatures
between 60° F and 65° F. Avoid placing the plants near drafts, excess heat or the dry air from
appliances, fireplaces, radiators or ventilating ducts.
Water and Fertilizer - Poinsettias require moderately moist soil. Water
the plants thoroughly when the soil surface feels dry to the touch. Remove the
plant from decorative pots or covers, and water enough to completely saturate
the soil. Do not allow the poinsettia to sit in any standing water; root rot
could result which could kill the plant. It is not necessary to fertilize the
poinsettia when it is in bloom.
Outside Placement - Since poinsettias are sensitive to cold weather,
frost and rain, outside placement during the winter months should be avoided.
However, in mild climates, an enclosed patio or entryway may be suitable
provided the night temperatures do not drop below 55º F. Make certain the
delicate bracts are well-protected from wind and cold rain.
If these tips are followed your poinsettia should stay beautiful through the
holidays and beyond.
After the Holidays - When the bracts age and lose their aesthetic appeal,
usually by late March or early April, cut the poinsettia back to about 8 inches
in height. By the end of May you should see vigorous new growth. Pruning may be
required during the summer to keep plants bushy and compact, but do not prune
after September 1. Keep the plants in indirect sun and water regularly.
Place your plants outdoors, where they can bask in the warmth of spring and
summer, after outside night temperatures average 55º F or above. Continue
regular watering during the growth period. Fertilize every 2 to 3 weeks
throughout the spring, summer and fall months with a well-balanced, complete
fertilizer. Around June 1, you may transplant your poinsettias into larger pots.
Select pots no more than 4 inches larger than the original inner pot. A soil mix
with a considerable amount of organic matter, such as peat moss or leaf mold, is
highly recommended. If you wish, you may transplant the poinsettias into a
well-prepared garden bed. Be sure the planting bed is rich in organic matter and
has good drainage.
Re-flowering - The poinsettia is a photoperiodic plant, meaning that it
sets bud and produces flowers as the Autumn nights lengthen. The plants will
naturally come into full bloom during November or December, depending upon the
flowering response time of the individual cultivar. Timing the bloom to coincide
closely with the Christmas holiday can be difficult without the controlled
environment of a greenhouse. Stray light of any kind, such as from outside
street lights or household lamps, could delay or entirely halt the re-flowering
process. Starting October 1, the plants must be kept in complete darkness for 14
continuous hours each night. Accomplish this by moving the plants to a totally
dark room, or by covering them with a large box overnight. During October,
November and early December, the plants require 6 - 8 hours of bright sunlight
daily, with nighttime temperatures between 60 - 70º F. Temperatures outside this
range may delay flowering. Continue the normal watering and fertilizer program.
Following this regime for 8 to 10 weeks should result in a colorful display of
blooms for the holiday season.
