Geographic conditions have major impacts on the growing season for any given area. The elevation, or the height above sea level, and temperature of a region are two of the main factors that affect the growing season.
In deserts growing season can last longer than any other on my presentation because its in a hotter climate and can grow longer with irrigation. Sometimes you can plant all year long.
Tropics are very similar to deserts because they both last longer than any other region. But the tropics don’t need irrigation because the weather usually brings rain often. Sometimes they can plant all year-round.
