Improved Farms are much more efficient for food production than Basic Farms with twice the production speed, and 1.5 times the number harvests before requiring fertilization, while being only slightly more costly.
As long as light is available to them, they can even grow crops in Caves. Any light source will do, even the light from multiple Fireflies.
Since the crops do not spoil before harvesting, Farms can be used for player's advantage to have a ready food supply for later, when food supplies may be rarer, such as during Winter. However, in Reign of Giants and Shipwrecked grown crops can be wilted during Summer and Dry Season, when not protected by an Ice Flingomatic.
