Answer:
Orange Groves are affected by the climate of the region. In the US, states such as Florida and Georgia are the biggest orange producers because of their climate. Also, oranges need good soil to grow, so dry soils are not suitable for growing oranges.
Nurseries are more "human controlled" than orange groves. A big human factor that plays a role in growing the food properly is temperature. If the temperature is too hot or cold, the plants may not grow properly and might even die. Also, many nurseries can control the humidity inside the nursery. Some plants require specific humidities to grow- and are vulnerable to a change in humidity.
Coffee plants require moist soil to be grown well. Thus, if the soil is too dry, the coffee plant may die. In other words, a coffee plant would grow much better in a farm, than a desert. Also, Coffee Plants require a high temperature, and that is why most of the world's coffee is grown in places like Africa and South America as they have hotter temperatures.
