Orange Astana

Oranges are sensitive to frost, and a common treatment to prevent frost damage when sub-freezing temperatures are expected, is to spray the trees with water, since as long as unfrozen water is turning to ice on the trees' branches, the ice that has formed stays just at the freezing point, giving protection even if air temperatures have dropped far lower.
Oranges can be grown, outdoors in warmer climates, and indoors in cooler climates. Oranges, like most citrus plants will not do well unless kept between 15.5°C - 29°C (60°F - 85°F).
Orange trees grown from the seeds of a store bought fruit may not produce fruit, and any fruit that is produced may be different than the parent fruit, due to modern techniques of hybridization.
