Question: I see poinsettias in stores already. If I buy one now, will it last through until New Year’s? Answer: Nowadays, poinsettias with proper care will continue to be colorful for two months or longer. The poinsettia has been the favorite Christmas flower for many years.
Where it grows native in the tropics it blooms naturally shortly before Christmas in response to the shortening day length. Poinsettias are grown in greenhouses where they can be forced into bloom much earlier than normal. Growers shorten the normal day length by covering the plants with black cloth.
Not only are poinsettias lasting longer, but they are available in an increasing variety of types and colors. To see the full range of what is available, I would recommend that you visit a nursery or greenhouse that actually grows its own plants. You will also be able to make sure that the plants have not been mishandled on the way from the greenhouse to the store.
The two main causes of premature leaf and flower bract drops on poinsettias are cold shock and over-watering. Poinsettias can be damaged by temperatures below 50 degrees. They can be damaged when moving from truck to store.
When purchased in a store when temperatures are below 50 degrees, they should be covered on the way between store and car. They should not be left in a car for long periods while you do other shopping. Poinsettias are grown in pots with holes for drainage.
Then they are usually wrapped with colored foil around the pot. If wate.
