I am in zone 8 Tucson, AZ. I would like to plant in west exposure morning sun 'til 10-10:30am. Can I do so if I heavily mulch root area when it fall below 50 degrees? The spot I want to use has an east wall and other wall faces south with 3 large trees, 1 mesquite east, 1 mesquite S/E and 1 very large pine on the S/SW end of bed. The light sounds OK to me but the temperature is the question. Can you send suggestions? Marylee

Mandevilla Vines are hardy in zones 9 - 11.
I know as gardeners, we like to try to push the growing zones, but in the case of a Mandevilla Vine you will not be able to winter over this plant
in zone 8.
