Fruit farming at home with organic manure gives bumper crop

People living in Indian villages grow fruit trees in homes. They only use food waste and organic items as fertilizer and obtain  a bumper crop.

For example see this lemon tree.

It is fed with peals of banana and other vegetables.
It has plenty of sun light and water.
The size, color and taste of fruit is excellent.
As it is grown without any synthetic fertilizers there are no other poisonous chemicals in fruit.

I think any body who have good soil, light, water and time can do it and enjoy the fruits of nature.
