For many, the rich color of poinsettias is a comforting symbol of the holidays. With proper care, the popular plant can last through the end of the year and beyond.

Poinsettias should be kept in a spot where daytime temperatures are 65 to 75 degrees F, and 60 to 65 at night. Temperatures above 75 will shorten the life of blooms, and below 60 degrees may cause root rot.

Place your poinsettia in a sunny window or the brightest areas of your room, but don’t let it touch cold window panes. Move plants away from drafty windows at night, or draw the drapes to avoid cold damage.

Poinsettias can be “finicky” when it comes to soil moisture. Avoid over-watering poinsettias because they do not like ‘wet feet'. On the other hand, if the plant is allowed to wilt (due to not getting enough water), it will drop some leaves.

To maintain proper moisture, stick a finger about ½ inch deep into the soil. If it’s dry to ½ inch, the plant needs water. When it becomes dry to the touch, water the plant with lukewarm water until some water runs out of the drainage hole, then discard the drainage water.

Are poinsettias poisonous?

Despite rumors to the contrary, poinsettia leaves are not poisonous to humans or animals.

The plant could cause an allergic reaction to the milky sap in the leaves, but there has never been a recorded case of poisoning due to a poinsettia.

Some members of the genus Euphorbia, to which the poinsettia belongs, have a toxin that can cause vomiting. The poinsettia, however, does not contain that toxin. It is still a good idea though to keep an eye on children and pets.
