What are good temperature ranges for Poinsettias?

Answer 1

Semi-tropical and tropical climates are the climates to which poinsettias (Euphorbia pulcherrima) are native.

Specifically, poinsettias are native to southwestern Mexico and Central America. Nowadays they can be grown outside their native range. But success depends upon the meeting of the plant's specific needs. For example, poinsettias cannot be grown in cold climates since the plant is susceptible to fatal injury from the bruising, drying winds of temperatures below their comfort zone of 60-80 degrees F/15.56- 26.67 degrees C.

Answer 2

Ideal growing conditions for poinsettias (Euphorbia pulcherrima) are the following:

1. Avoidance of bruising of leaves by adequate spacingbetween plants and plant containers inside and out;

2. Control of disease by avoiding under- and over-watering* and by preventing exposure to splashing or standing water and to such pesticides as weed killers;

3. Exposure to intense light, but from a protective position of light shade;

4. Fertile, moist, well-aerated soil with good drainage and low level of total soluble salts;

5. Good sanitation;

6. Humid climate with temperatures ranging in the 60-80 degrees F/15.56-26.67 degrees C range;

7. Regular watering schedule* to avoid drying out, but without waterlogging the soil;

8. Room for the development of fibrous roots: Poinsettias do not like a tight fit in containers or in the ground!

9. Soil pH in the acidic range of 4.5-6.5 that in its upward limits is heading into the neutral zone.

*Generally, plants can be watered every 7-10 days. But the soil regularly can be monitored by look and by touch. A simple, physical check involves sticking a sharp object into the soil. The soil is too dry if the object comes out clean of any particles, too wet if the particles look muddy and just right if tiny soil particles form a freckled, speckled pattern over the object's surface.

Answer 3

Good temperature ranges for Poinsettias are 65-75 degrees.
