Q. Can poinsettia be put outside in the spring and summer? What temperature range suits it?
Yes, poinsettia, Euphorbia pulcherrima, can be put outside during the warm months. But it is a tender tropical plant, so wait until the temperature is consistently above 50°F at night before placing it outside.
You will need to acclimate it by taking it out gradually, not all at once. When the days start to warm up into the 50s and 60s you can put it out during the day and take it inside at night. Gradually you can leave it outside for longer periods of time. After a couple of weeks you can leave it out all night, provided the nights don't get too cold.
