I bought a large, beautiful poinsettia for the holiday that I’d like to keep as long as possible. How long will it last? I’d like to keep it growing until spring and plant it outdoors when the weather is warmer.
To keep a poinsettia looking its best through the holidays, here are the basics: Place it in a spot in the house that gets indirect light in a room that’s not too warm – 68 to 70 degrees is best. Make sure it’s not near heating vents or in a place where there’s a cold draft. Keep the soil moist, but don’t let the pot sit in water. In fact, if there is a foil wrapper around the plastic pot, remove the wrapper when you water to let it drain. When a poinsettia wilts, that may be an indication that it’s staying too wet.
If you take care of it, the poinsettia should last through the holidays and well beyond.
Poinsettia is a tropical plant, native to Mexico, so don’t be in a rush to get it outside. As spring approaches, cut it back to about eight inches tall and fertilize with an all-purpose plant food. After there is no longer any danger of frost, re-pot the poinsettia and set it outdoors, or plant it in the ground where it will grow into a nice, interesting green plant that will last until the first frost.
What we think of as poinsettia flowers are technically bracts, or modified leaves. The yellow flowers are in the center of the bracts. Some gardeners are able to “re-bloom” a poinsettia plant, but it takes patience and impeccable timing to provide the right conditions of light and dark needed to produce the colorful bracts.
