The area of the kitchen garden sufficient for a family of 4 is 200 m².
The traditional kitchen garden is a space separate from the rest of the residential garden the ornamental plants and lawn areas. It is used for growing edible plants and often some medicinal plants.
The size of a kitchen garden depends upon the availability of land and the number of persons for whom vegetables are to be provided.
With succession cropping and intercropping, five cents of land would be adequate to supply vegetables for an average family of four to five persons.
