Fruit straight from the farm is better than from the market
At the grocery store, the way they keep the fruit, it all looks very clean, one thing to keep in mind is that the fruit is picked slightly before it is perfectly ripe and the fruit is not able to go bad on the way to the store so it gets packed, travels some way and then sits on some shelves, so that can affect the taste of the fruit which can also be weak. For an example, take a mango, a mango can be very yellow on the outside, but when you cut it, it does not have a strong smell and it is not very juicy. Sure, you can still eat a mango, it'll fill you up but the flavor is just not that great.
Farm fruit is way better, because they pick the fruit when it is ripe, and it does not get to sit around for a long time like in a store. If you buy a pineapple from the store that was cut that day, it will have a strong smell, a lot of juice and the taste will be really sharp and sweet at the time. Even a small orange from a farm can be much juicier than one from the market.
The outside of the fruit is different as well. It looks different at the market because the workers sort them. They make them look the same size and the same color. On farms, they do not do this. Some are small, some have marks and some are not as smooth. But that does not mean they are not good. Guavas that look rough on the outside could be the best ones.
The fruit from the market can be really soft. Sometimes it can be hard on the inside because it was picked too early. Bananas bought near a farm are soft, sweet, and have no black spots. Bananas from the market are soft on the outside but the inside is hard.
The location of the fruit determine how much it costs. Fruit from the farm is cheaper. Fruit that is the same but in town is more because of the cost of getting it and storing it.
You have more options when buying fruit from a farm than buying fruit from a store or farmers market. The farmers market has a set variety and quantity of items. You can grab a fruit from a tree or a fruit from the ground at a farm. Many people choose fruit by smell and by squeezing the fruit, and they do this before grabbing the fruit.
