Fruit trees have special maintenance needs. They are subject to pest infestations that need to be controlled, the fruit has to be harvested on a schedule. The people who know how to do that kind of stuff are called farmers. Whether they contract it out or handle it in house, Apple is getting into the farming business.
this is far from true.
the building I'm currently working in here in arizona, is almost completely surrounded by various citrus trees, ranging from oranges, to grapefruits, to lemons, and so forth.
we have a company we contract who comes by weekly for general maintenance and then more often when the fruit is ready to be harvested.
but i would hardly call us here at the call center "farmers"
fruit trees are not that hard to maintain if your goal is NOT to sell the fruit. sure if you want the best, freshest and most beautiful apples or oranges, you need to be on top of it 100%. but if its more for decorative purposes, and not your lively hood, general maintenance is usually fine. and there are MANY companies both here and in CA that specialize in just this.
if anything having fruit trees to harvest can sometimes reduce the cost of the landscaping itself as a lot of local businesses will harvest the fruit and then sell it for a small profit.
IE: the company we have here, will harvest the fruit from various properties around the city, that they maintain, in return they charge a much lower fee during the time, or sometimes even offer to do the harvesting/general maintenance and landscaping that time of the year for free, and will then sell the good fruits harvested to local farmers markets and such.
sure, those who work at that company might be considered "farmers" but again, our company would hardly been considered a "farm"
its not a billion dollar industry but deffinetly not expensive for a company like apple to figure it all out.
**as a side note, might as well grab myself some overalls and a straw hat, as considering i have a modestly sized orange tree in my back yard(left over from the previous owners/builders of the house) and considering i go out and water the thing a few times a week, by your definition i am a true farmer i guess.
